[0033] See also Figure 1 to Figure 2 , Figure 1 is a schematic cross-sectional view of the magnetic circuit system of the present application, Figure 2 yes Figure 1 Schematic diagram of the exploded magnetic circuit system shown.

[0034] The magnetic circuit system 5 is an important component of the bone conduction earphone, and its function is to provide a constant magnetic field. The constant magnetic field further cooperates with the changing magnetic field generated by the voice coil in the energized state to convert the electrical signal into mechanical vibration, which is directly transmitted to the auditory nerve through the bones and human tissues, so that the user can produce an auditory response.

[0035] like Figure 1As shown, the magnetic circuit system 5 includes a magnetic shield 51, a bottom magnetic plate 52, a magnetic shield 53, a top magnetic plate 54 and a plastic part 55. The magnetic shield 51 includes a bottom wall 512 and an annular peripheral wall 514 connected to the bottom wall 512, thereby forming a receiving cavity 516. The bottom magnetic plate 52, the magnetic shield 53, the top magnetic plate 54 and the plastic part 55 are received in the receiving cavity 516 and are sequentially stacked on the bottom wall 512, wherein the adjacent end faces of the bottom magnetic plate 52 and the top magnetic plate 54 have the same polarity.

[0036] In the above-mentioned magnetic circuit system 5, since the bottom magnetic plate 52, the magnetic conductive plate 53, the top magnetic plate 54 and the plastic part 55 need to be stacked in a relatively small accommodating cavity 516, and the adjacent end faces of the bottom magnetic plate 52 and the top magnetic plate 54 have the same polarity, the difficulty of assembling the magnetic circuit system 5 is increased. Therefore, in the present application, the magnetic circuit system 5 is assembled in steps through various assembly jigs and assembly equipment described below to reduce the difficulty of assembly.

[0037] like Figure 2 As shown, during the assembly process of the magnetic circuit system 5, the plastic part 55 and the top magnetic plate 54 are first stacked and assembled into the first semi-finished product 550, and the bottom magnetic plate 52 and the magnetic conductive cover 51 are assembled into the second semi-finished product 510, and then the magnetic conductive plate 53 and the first semi-finished product 550 are stacked on the bottom magnetic plate 52 in sequence, and the first semi-finished product 550, the magnetic conductive plate 53 and the second semi-finished product 510 are fastened to form the magnetic circuit system 5.

[0038] Specifically, the first semi-finished product 550 includes a top magnetic plate 54 and a plastic part 55 which are stacked and fixed to each other, and the second semi-finished product 510 includes a magnetic cover 51 and a bottom magnetic plate 52 which is accommodated in the accommodating cavity 516 and fixed to the bottom wall 512 .

[0039] See also Figure 3 , Figure 3 1 is a schematic diagram of the structure of an embodiment of an automatic assembly system provided by the present application. The automatic assembly system 100 includes an assembly jig and an automatic assembly device, the assembly jig includes a first assembly jig 12, a second assembly jig 14 and a third assembly jig 16, and the automatic assembly device includes a first assembly device 2, a second assembly device 3 and a third assembly device 4.

[0040] Among them, the first assembly equipment 2 is used to stack and fix the top magnetic plate 54 and the plastic part 55 through the first assembly jig 12 to form a first semi-finished product 550; the second assembly equipment 3 is used to place the bottom magnetic plate 52 into the accommodating cavity 516 through the second assembly jig 14 and stack and fix it with the bottom wall 512 of the magnetic cover 51 to form a second semi-finished product 510; the third assembly equipment 4 is used to stack and fix the first semi-finished product 550 and the magnetic plate 53 on the bottom magnetic plate 52 through the third assembly jig 16.

[0041] See also Figure 4 and Figure 5 The first assembly jig 12 includes a first carrier 120 and a magnetic member 122. The first carrier 120 is provided with a first positioning groove 1210, a second positioning groove 1211 and a receiving groove 1212 which are sequentially connected from the surface of the first carrier 120 to the inside. The second positioning groove 1211 is provided at the bottom of the first positioning groove 1210, the receiving groove 1212 is provided at the bottom of the second positioning groove 1211, and the magnetic member 122 is provided in the receiving groove 1212. Among them, the first positioning groove 1210 is used to position the top magnetic plate 54, the second positioning groove 1211 is used to position the plastic part 55, and the magnetic member 122 is used to magnetically absorb the top magnetic plate 54 and prevent the magnetic pole of the top magnetic plate 54 from being reversed.

[0042] When assembling the first semi-finished product 550, the plastic part 55 and the top magnetic plate 54 are sequentially arranged in the second positioning groove 1211 and the first positioning groove 1210, and the top magnetic plate 54 arranged in the first positioning groove 1210 is stacked and bonded to the plastic part 55 to form the first semi-finished product 550. In other embodiments, the plastic part 55 and the top magnetic plate 54 can be fixed by hot melting or other fixing methods.

[0043] The first carrier 120 is made of a non-magnetic material, which is neither magnetic nor magnetizable, for example, the first carrier 120 is made of stainless steel or copper, etc. The edge of the opening end of the first positioning groove 1210 may also be chamfered to facilitate the assembly of the top magnetic plate 54.

[0044] A first vent hole 1213 is also provided at the bottom of the first positioning groove 1210, and a second vent hole 1214 is provided at the bottom of the second positioning groove 1211. The aperture of the first vent hole 1213 is larger than that of the second vent hole 1214, so as to avoid the local positive pressure that may be formed when the plastic part 55 and the top magnetic plate 54 are assembled with the corresponding positioning groove, and avoid the positioning effect being adversely affected by the local positive pressure, thereby ensuring that the plastic part 55 and the top magnetic plate 54 are stacked and assembled through the first carrier 120. Further, the first vent hole 1213 and the second vent hole 1214 can also be connected to the corresponding negative pressure device, thereby providing negative pressure in the corresponding positioning groove to accelerate the positioning process of the plastic part 55 and the top magnetic plate 54.

[0045] The receiving groove 1212 includes a first cavity 1216 and two second cavities 1217 disposed on both sides of the first cavity 1216 . The first cavity 1216 and the two second cavities 1217 are connected. The first cavity 1216 receives the magnetic element 122 , and the second cavity 1217 is used to avoid the plastic element 55 .

[0046] A positioning portion 1215 is provided on the side of the first carrier 120, and the positioning portion 1215 is used to coordinately position the first carrier 120 on the first assembly device 2. The positioning portion 1215 may be a positioning groove, a positioning hole, or the like.

[0047] See also Figure 6 and Figure 7 The second assembly fixture 14 includes a second carrier 140 and a third carrier 142. The second carrier 140 is provided with a magnetic cover positioning groove 1402 for positioning the annular circumferential wall 514 of the magnetic cover 51; the third carrier 142 is provided with a guide channel 1422. The third carrier 142 is assembled with the second carrier 140, and then the third carrier 142 is inserted into the accommodating cavity 516 of the magnetic cover 51 located in the magnetic cover positioning groove 1402, so that the guide channel 1422 locates an assembly area on the bottom wall 512 that is assembled with the bottom magnetic plate 52. The bottom magnetic plate 52 is placed in the accommodating cavity 516 through the guide channel 1422, and then can be assembled and fixed with the assembly area on the bottom wall 512, and is spaced from the annular circumferential wall 514.

[0048] The bottom magnetic plate 52 is aligned with the assembly area through the guide channel 1422, and the bottom magnetic plate 52 is fixed to the bottom wall 512, so that the magnetic cover 51 and the bottom magnetic plate 52 are stacked and fixed to form the second semi-finished product 510. The bottom magnetic plate 52 and the bottom wall 512 can also be fixed by adhesive or other fixing methods.

[0049] Specifically, the second carrier 140 is first used to locate the assembly area on the bottom wall 512, and then the bottom magnetic plate 52 is superimposed on the assembly area to achieve stacking and fixing of the bottom magnetic plate 52 and the bottom wall 512 at a specific position to form a required gap between the bottom magnetic plate 52 and the annular circumferential wall 514, thereby effectively improving the assembly accuracy of the magnetic cover 51 and the bottom magnetic plate 52 and reducing the difficulty of assembly.

[0050] In this embodiment, the third carrier 142 includes a first sleeve 1421 and a second sleeve 1423 arranged on one side of the first sleeve 1421, the guide channel 1422 passes through the first sleeve 1421 and the second sleeve 1423, the second sleeve 1423 is inserted into the accommodating cavity 516, and the first sleeve 1421 is superimposed on the second carrier 140 and assembled in alignment with the second carrier 140.

[0051] By using the magnetic cover positioning groove 1402 to position the annular circumferential wall 514 and using the first sleeve 1421 to align and assemble with the second carrier 140, it is possible to avoid excessive friction or collision between the second sleeve 1423 and the inner side of the annular circumferential wall 514 due to alignment deviation during the insertion of the second sleeve 1423 into the accommodating cavity 516, which is beneficial to reducing damage to the magnetic cover 51 and improving positioning accuracy.

[0052] The height of the second sleeve 1423 along the extending direction of the guide channel 1422 is smaller than the depth of the accommodating cavity 516 in the extending direction to prevent the second sleeve 1423 from abutting against the bottom wall 512 and causing deformation of the bottom wall 512 .

[0053] The second carrier 140 is further provided with an alignment post 144, and the first sleeve 1421 is provided with an alignment hole 1424, so that when the first sleeve 1421 and the second carrier 140 are aligned and assembled, the alignment post 144 is correspondingly penetrated into the alignment hole 1424, so that the second carrier 140 and the third carrier 142 are aligned and assembled through the alignment post 144 and the alignment hole 1424. In other embodiments, the alignment hole can be provided on the second carrier 140, and the alignment post can be provided on the first sleeve 1421.

[0054] In this embodiment, the magnetic cover 51 is provided with a first through hole 511, the bottom magnetic plate 52 is provided with a second through hole 520, and the bottom of the magnetic cover positioning groove 1402 is provided with an avoidance hole 1406 corresponding to the first through hole 511 and the second through hole 520. The first through hole 511 and the second through hole 520 can be used for fasteners to pass through during the subsequent assembly of the finished product.

[0055] The bottom of the magnetic cover positioning groove 1402 is provided with an avoidance hole 1406 to avoid that when the bottom magnetic plate 52 is bonded to the bottom wall 512 by gluing, the adhesive used for bonding has a high probability of covering the first through hole 511 and the second through hole 520, and prevents the adhesive from solidifying and blocking the first through hole 511 and the second through hole 520, so that the magnetic circuit system 5 cannot be fixed by fasteners when it is subsequently assembled. At the same time, if the adhesive solidifies and blocks, the first through hole 511 and the second through hole 520 can be dredged by using a rod through the avoidance hole 1406.

[0056] A vent hole 1407 is also provided at the bottom of the magnetic cover positioning groove 1402 to prevent the magnetic cover 51 from being placed in the magnetic cover positioning groove 1402 and causing local positive pressure to affect assembly.

[0057] The side wall of the second stage 140 is provided with a positioning portion 1404, and the positioning portion 1404 is used to define the position of the second stage 140 on the second assembly device 3. The positioning portion 1404 can be a positioning groove, a positioning hole, etc.

[0058] See also Figures 8 to 9 The third assembly jig 16 includes a fourth carrier 160 and a fifth carrier 162. The fourth carrier 160 is provided with a first semi-finished product positioning groove 1602 for simultaneously positioning the magnetic conductive plate 53 and the first semi-finished product 550. The bottom of the first semi-finished product positioning groove 1602 is provided with an avoidance hole 1601 for avoiding the first fastener; the fifth carrier 162 is provided with a second semi-finished product positioning groove 1622 for positioning the second semi-finished product 510. The bottom of the second semi-finished product positioning groove 1622 is provided with a positioning hole 1621 for accommodating the second fastener.

[0059] Among them, the fourth carrier 160 is used to align and snap fit with the fifth carrier 162, so as to stack the first semi-finished product 550 and the magnetic conductive plate 53 carried by the fourth carrier 160 and the second semi-finished product 510 carried by the fifth carrier 162 on each other, and the first fastener is sequentially passed through the plastic part 55, the top magnetic plate 54, the magnetic conductive plate 53, the bottom magnetic plate 52 and the magnetic conductive cover 51 and is fixedly connected with the second fastener located on the side of the magnetic conductive cover 51 away from the plastic part 55.

[0060] In this embodiment, the first fastener may be a screw, and the second fastener may be a nut; or, the first fastener may be a latch, and the second fastener may be a buckle, and the latch and the buckle are fixed by being snap-connected.

[0061] In other embodiments, the second fastener and the positioning hole 1621 may be eliminated, and only the first fastener is used to sequentially penetrate and fix the first semi-finished product 550, the magnetic conductive plate 53, and the second semi-finished product 510 through the avoidance hole 1601 to form the magnetic circuit system 5. In this case, the first fastener is, for example, a pin, which can independently penetrate and fix the first semi-finished product 550, the magnetic conductive plate 53, and the second semi-finished product 510 to form the magnetic circuit system 5. Alternatively, the first through hole 511 of the magnetic conductive cover 51 is a threaded hole, and the first fastener is a screw, and the first fastener is screwed and fixed to the magnetic conductive cover 51 to form the magnetic circuit system 5.

[0062] The fourth carrier 160 is further provided with a magnetic attraction member 1603, which magnetically attracts the first semi-finished product 550 and the magnetic conductive plate 53 located in the first semi-finished product positioning groove 1602, thereby preventing the magnetic conductive plate 53 and the first semi-finished product 550 from falling off when the fourth carrier 160 is buckled relative to the fifth carrier 162.

[0063] The fifth carrier 162 is provided with an avoidance notch 1627 , and the avoidance notch 1627 is used to avoid the clamping mechanism clamping the fourth carrier 160 , so that the fourth carrier 160 and the fifth carrier 162 can be relatively locked.

[0064] An avoidance hole 1604 is also provided at the bottom of the first semi-finished product positioning groove 1602, and the avoidance hole 1604 is connected to the first semi-finished product positioning groove 1602. After the magnetic circuit system 5 is formed, the plastic part 55 can be pressed against by the avoidance hole 1604 to separate the fourth carrier 160 and the magnetic circuit system 5, and ensure that the magnetic circuit system 5 after assembly is located in the fifth carrier 162.

[0065] In this embodiment, the magnetic member 1603 is disposed on the side of the fourth stage 160 away from the first semi-finished product positioning groove 1602, and the avoidance hole 1604 runs through the magnetic member 1603. The avoidance hole 1604 is used for the push rod to be inserted and push against the first semi-finished product 550 when the fourth stage 160 and the fifth stage 162 are separated. Optionally, the magnetic member 1603 can be staggered with the avoidance hole 1604.

[0066] The fifth carrier 162 is further provided with a guide post 1626, and the fourth carrier 160 is provided with a guide hole 1608, and the guide hole 1608 is used for alignment and guidance with the guide post 1626. The fourth carrier 160 and the fifth carrier 162 are aligned and fastened through the guide hole 1608 and the guide post 1626, thereby being able to solve the problem that the fourth carrier 160 and the fifth carrier 162 are difficult to align and fit, or even easy to be misaligned, because the adjacent end faces of the bottom magnetic plate 52 and the top magnetic plate 54 have the same polarity, and the first semi-finished product 550 and the second semi-finished product 510 repel each other magnetically. Therefore, after the fourth carrier 160 and the fifth carrier 162 are aligned and fastened, the guide hole 1608 is penetrated in the guide post 1626, which is convenient for alignment and fastening, and can avoid mutual misalignment.

[0067] The fourth carrier 160 is further provided with an annular positioning rib 1607, which is arranged around the first semi-finished product positioning groove 1602. The annular positioning rib 1607 is inserted into the accommodating cavity 516 as the fourth carrier 160 and the fifth carrier 162 are aligned and snapped together to locate the position of the bottom magnetic plate 52 in the accommodating cavity 516, and enable the first semi-finished product 550 and the magnetic conductive plate 53 to be stacked on the bottom magnetic plate 52.

[0068] The fourth carrier 160 is further provided with an alignment groove 1606, which is arranged around the annular positioning rib 1607. The fifth carrier 162 is provided with an alignment protrusion 1624, which is arranged around the second semi-finished product positioning groove 1622. The alignment groove 1606 is aligned and snapped with the alignment protrusion 1624.

[0069] In this embodiment, a positioning groove 1606 is set on the fourth carrier 160 to form an annular positioning rib 1607 between the positioning groove 1606 and the first semi-finished product positioning groove 1602. When the positioning protrusion 1624 is aligned and engaged with the positioning groove 1606, the annular positioning rib 1607 is inserted into the accommodating cavity 516 through the area surrounded by the positioning protrusion 1624.

[0070] Among them, the guide column 1626 and the guide hole 1608 are guided with relatively low precision, while the alignment groove 1606 and the alignment protrusion 1624 are positioned and assembled with relatively high precision, so that the annular positioning rib 1607 can more accurately position the position of the bottom magnetic plate 52 in the accommodating cavity 516.

[0071] Further reading Fig.10The third assembly fixture 16 also includes a positioning platform 164, and the positioning platform 164 is provided with a first positioning cavity 1642 and a second positioning cavity 1644. The first positioning cavity 1642 is used to carry and position the fourth platform 160, and the second positioning cavity 1644 is used to carry and position the fifth platform 162, so as to facilitate the synchronous transportation of the paired fourth platform 160 and the fifth platform 162 through the positioning platform 164, thereby facilitating the use of the paired fourth platform 160 and the fifth platform 162 to assemble the magnetic circuit system 5.

[0072] The positioning platform 164 is further provided with an avoidance gap 1643 communicating with the first positioning cavity 1642 and an avoidance gap 1645 communicating with the second positioning cavity 1644 . The avoidance gap 1643 and the avoidance gap 1645 are both used for avoiding the clamping mechanism that clamps the fourth platform 160 .

[0073] See also Fig.11 In this embodiment, the first assembly equipment 2 generally includes a first assembly jig conveyor line 21, a plastic parts assembly station 22, a glue dispensing station 23, a top magnetic plate assembly station 24, a pressing station 25, a glue blowing station 26, a material unloading station 27, an empty load detection station 28 and a purge station 29.

The upstream flipping device 420 is used to flip the fourth carrier 160 so as to align and engage with the fifth carrier 162, and the downstream flipping device 420 is used to separate the fourth carrier 160 and the fifth carrier 162 that are engaged with each other.

[0099] In other embodiments, the number of the flipping device 420 can also be one, and the flipping device 420 can reciprocate upstream and downstream of the guide pressing member 422 to take into account the alignment, buckling and separation of the fourth carrier 160 and the fifth carrier 162.

[0100] See also Fig.14 The flip device 420 includes a telescopic mechanism 4201, a lifting mechanism 4203, a rotating mechanism 4205 and a clamping mechanism 4207. The clamping mechanism 4207 is used to clamp the fourth carrier 160.

[0101] When separating the engaged fourth platform 160 and the fifth platform 162, the telescopic mechanism 4201 is used to drive the clamping mechanism 4207 to move toward the notch on the third assembly jig conveyor line 410, so that one clamping end of the clamping mechanism 4207 is located on the side facing the fourth platform 160 and the fifth platform 162 by avoiding the notch 1627, and the other clamping end is located on the other side opposite to the fourth platform 160 and the fifth platform 162, thereby clamping the fourth platform 160 from both sides of the fourth platform 160.

[0102] After the flipping device 420 aligns and fastens the fourth carrier 160 and the fifth carrier 162 , the fastened fourth carrier 160 and the fifth carrier 162 will pass through the guide pressing member 422 , which is used to press the first semi-finished product 550 and the second semi-finished product 510 which repel each other.

[0103] See also Fig.15 The guide and holding member 422 is provided with a guide slope 4221 and a holding plane 4223. The third assembly jig conveyor line 410 conveys the fourth carrier 160 and the fifth carrier 162 which are interlocked with each other through the guide slope 4221 and the holding plane 4223 in sequence. The fourth carrier 160 and the fifth carrier 162 which are interlocked with each other are gradually interlocked and tightly fitted with each other under the action of the guide slope 4221. The holding plane 4223 is used to keep the fourth carrier 160 and the fifth carrier 162 in a tightly fitted state.

[0104] The assembly opening 4220 is located on the holding plane 4223. After the assembly opening 4220 and the avoidance hole 1601 are aligned, the assembly mechanism 424 inserts fasteners through the assembly opening 4220 and the avoidance hole 1601 to the first semi-finished product 550, the magnetic conductive plate 53 and the second semi-finished product 510 to fix the magnetic circuit system 5 into a whole.

[0105] The assembly mechanism 424 includes a fastener feeder 4241 and an electric screwdriver 4243 . The electric screwdriver 4243 loads the first fastener from the fastener feeder 4241 , and inserts the first fastener into the assembly port 4220 and the avoidance hole 1601 to assemble the magnetic circuit system 5 .

[0106] The electric screwdriver device 4243 includes a driving mechanism and an electric screwdriver. The driving mechanism drives the electric screwdriver to load the first fastener from the fastener feeder 4241 and aligns the electric screwdriver with the assembly port 4220 to insert the first fastener into the magnetic circuit system 5.

[0107] In this embodiment, the first fastener is a screw, which is fixedly connected to the second fastener (nut) located in the positioning hole 1621 so that the magnetic circuit system 5 forms a whole.

[0108] Therefore, before the second semi-finished product assembly station 414 loads the second semi-finished product 510 into the second semi-finished product positioning groove 1622 , the second fastener assembly station 432 loads the second fastener into the positioning hole 1621 .

The second fastener loading device 4321 is used to provide the second fasteners in sequence, and the second fastener picking device 4323 is used to load the second fasteners provided in sequence into the positioning holes 1621 .

[0110] After forming the magnetic circuit system 5, the fourth carrier 160 and the fifth carrier 162 need to be separated to facilitate the removal of the magnetic circuit system 5. However, during the removal of the fourth carrier 160, the magnetic circuit system 5 may move synchronously with the fourth carrier 160, thus causing difficulty in subsequent material removal.

[0111] See also Fig.16 The push rod mechanism 426 includes a push rod 4261 and a push rod driving mechanism 4263. The push rod driving mechanism 4263 drives the push rod 4261 to penetrate into the avoidance hole 1604 and press against the magnetic circuit system 5, and drives the push rod 4261 to be pulled out of the avoidance hole 1604 after the fourth carrier 160 is separated from the magnetic circuit system 5. The flipping device 420 is also used to lift the fourth carrier 160 along the push rod 4261 when the push rod 4261 is inserted into the avoidance hole 1604, flip the fourth carrier 160 after the push rod 4261 is pulled out of the avoidance hole 1604, and place the fourth carrier 160 on the carrier conveying line 410, so that the fourth carrier 160 and the corresponding fifth carrier 162 are arranged side by side.

[0112] The present application sets a push rod mechanism 426 to push against the magnetic circuit system 5 when separating the interlocking fourth platform 160 and the fifth platform 162, so as to ensure that the formed magnetic circuit system 5 is located on the fifth platform 162, which is convenient for subsequent detection and sorting of the magnetic circuit system 5.

[0113] The detection device 428 includes an image acquisition device, which is used to acquire an image of the magnetic circuit system 5, and then identify whether the magnetic circuit system 5 has defects such as cracks or dislocations based on the acquired image. If no defects are detected, the quality of the magnetic circuit system 5 is qualified, and if defects are detected, the quality of the magnetic circuit system 5 is unqualified. For example, when the first semi-finished product 550, the magnetic conductive plate 53, and the second semi-finished product 510 are fixed by screws, cracks are generated on the top magnetic plate 54 due to excessive force, which will cause the magnetic circuit system 5 to be scrapped, so the unqualified magnetic circuit system 5 can be identified by the detection device 428.

[0114] The detection device 428 feeds back the detection result to the sorting station 430, and the sorting station 430 is used to sort the magnetic circuit system 5 detected by the detection device 428, and put the magnetic circuit system 5 with qualified quality on a tray, and sort the magnetic circuit system 5 with unqualified quality into a recycling box.

[0115] The present application also provides a jig conveyor line 600, which can be used as a conveyor line for the various assembly jigs described above. Figures 17 to 19 , Fig.17 is a structural schematic diagram of an embodiment of a fixture conveyor line provided by the present application, Fig.18 yes Fig.17 The schematic diagram of the partial cross-section structure of the fixture conveyor line shown in the figure. Fig.19 It is a structural schematic diagram of a specific application scenario of the fixture conveyor line provided in this application.

[0116] The fixture conveying line 600 generally includes a conveying assembly 610 and a power source 620 . The power source 620 is used to drive the conveying assembly 610 to reciprocate so as to convey the fixture 630 located at the conveying assembly 610 .

[0117] Among them, the conveying assembly 610 includes a conveying rod 612, a plurality of push blocks 614 and a plurality of rebound members 616. The conveying rod 612 is used to support a plurality of jigs 630 arranged at intervals. The conveying rod 612 is further provided with a plurality of avoidance grooves 611. The plurality of push blocks 614 are arranged in the corresponding avoidance grooves 611 and can extend and retract from the avoidance grooves 611. The rebound member 616 is elastically supported between the push blocks 614 and the conveying rod 612 to realize the extension and retraction of the push blocks 614 relative to the avoidance grooves 611. The power source 620 is used to drive the conveying rod 612 to reciprocate.

[0118] The power source 620 may be a cylinder, or a motor and a transmission mechanism, which can drive the conveying rod 612 to reciprocate.

[0119] When the power source 620 drives the conveying rod 612 to move forward, the push block 614 in the extended state pushes the corresponding fixture 630 to move forward. When the power source 620 drives the conveying rod 612 to retreat, the push block 614 is blocked by the fixture 630 on the retreat path and overcomes the elastic force of the rebound member 616 to retract. After passing the fixture 630, the push block 614 returns to the extended state under the action of the rebound member 616.

[0120] In this embodiment, the push block 614 is rotatably connected to the conveying rod 612 via a connecting shaft, and the resilient member 616 is a torsion spring, which is sleeved on the connecting shaft and elastically supported between the push block 614 and the conveying rod 612 .

[0121] Among them, the push block 614 is provided with a push surface 6141, a rest surface 6143 and an inclined guide surface 6145, the inclined guide surface 6145 connects the push surface 6141 and the rest surface 6143, the push surface 6143 is used to push the jig 630 forward, and the rest surface 6143 is used to rest against the groove wall of the avoidance groove 611 under the action of the rebound member 616 to limit the extension distance of the push block 614, and the push surface 6141 and the rest surface 6143 are arranged back to back; wherein, when the push block 614 is in an extended state, the distance between the inclined guide surface 6145 and the conveying rod 612 gradually decreases along the direction from one side of the push surface 6141 to the rest surface 6143.

[0122] When the conveying rod 612 moves forward, the push block 614 in the extended state pushes the corresponding jig 630 to move forward because the abutment surface 6143 abuts against the groove wall of the avoidance groove 611 under the action of the rebound member 616; when the conveying rod 612 retreats, the push surface 6141 does not abut against the groove wall of the avoidance groove 611, and the jig 630 abuts against the abutment surface 6143 or the inclined guide surface 6145, so that the push block 614 compresses the rebound member 616 and retracts into the avoidance groove 611, so that the conveying rod 612 pushes the jig 630 forward one step length in one reciprocating motion, and the jig 630 can be conveyed more accurately.

[0123] Optionally, the resilient member 616 may also be a tension spring, which is elastically supported between the push block 614 and the conveying rod 612 so that the abutting surface 6143 abuts against the groove wall of the avoidance groove 611 .

[0124] In other embodiments, the push block 614 is slidably disposed in the avoidance groove 611 , and the push block 614 extends relative to the avoidance groove 611 under the elastic action of the rebound member 616 , and when the conveying rod 612 retracts, the push block 614 overcomes the elastic force of the rebound member 616 and retracts due to the obstruction of the fixture 630 .

[0125] like Fig.19 As shown, the conveying assembly 610 also includes a guide plate 617 clamped on both sides of the conveying rod 612, and the conveying rod 612 moves along the direction defined by the two guide plates 617. The jig 630 is provided with a positioning groove 632 on the side facing the guide plate 617, and a plurality of elastic positioning columns 618 are arranged at intervals on the guide plate 617 on at least one side. The elastic positioning columns 618 are used to align with the positioning groove 632. The jig 630 can release the positioning cooperation with the current elastic positioning column 618 when pushed forward by the push block 614, and move to the next adjacent elastic positioning column 618 for positioning cooperation, and when the conveying rod 612 is withdrawn, the jig 630 maintains alignment with the elastic positioning column 618 to cause the push block 614 to retract.

[0126] The conveying assembly 610 further includes a cover plate 619 , and at least one side of the guide plate 617 is connected to the cover plate 619 . The cover plate 619 covers the side of the fixture 630 away from the conveying rod 612 to prevent the fixture 630 from falling off the conveying rod 612 due to vibration.

[0127] In some embodiments, the guide plate 617 is further provided with a notch for the clamping mechanism 4207 to clamp the fixture 630 .

[0130] In this embodiment, the jig conveyor line 600 includes four sets of paired conveyor assemblies 610 and a power source 620, wherein the conveyor rods 612 of three sets of conveyor assemblies 610 are provided with a row of avoidance grooves 611 arranged along the conveying direction, and the conveyor rods 612 of another set of conveyor assemblies 610 are provided with multiple rows of avoidance grooves 611 arranged along the conveying direction.

The conveying mechanism 710 is provided with a conveying channel 712, and the conveying channel 712 is used to convey multiple workpieces arranged in sequence; the turntable mechanism 720 includes a turntable 722 and a power source 724. The turntable 722 is provided with a transfer groove 723. The power source 724 is connected to the turntable 722 and is used to drive the turntable 722 to rotate.

[0137] Among them, the power source 724 drives the turntable 722 to rotate. When the turntable 722 is in the first position, the transfer slot 723 is docked with the conveying channel 712, so that the workpiece output by the conveying channel 712 is transferred to the transfer slot 723. When the turntable 722 is in the second position, the transfer slot 723 carrying the workpiece is offset from the conveying channel 712, and the workpiece in the transfer slot 723 is in a pick-up state.

[0138] By setting up the turntable mechanism 720, the workpiece located in the transfer groove 723 can be staggered with the workpiece in the conveying channel 712 and can be in a pick-up state, thereby avoiding the situation where the remaining unpicked workpieces in the conveying channel 712 are driven when the workpiece is picked up, causing the workpieces in the conveying channel 712 to be disordered or disturbed and fall off from the conveying channel 712.

[0139] Among them, at least one transfer slot 723 is provided on the turntable 722. When a plurality of transfer slots 723 are provided, the plurality of transfer slots 723 are evenly distributed on the turntable 722, thereby increasing the material loading rate.
