[0038] At present, in the production process of this type of electronic components, the accessories are usually manually inserted into the mounting shell to achieve assembly, so as to improve the plug-in accuracy of the accessories. However, the efficiency of manual pin insertion is low and the cost investment is high. There are also a small number of mechanical pin insertion operations. However, the mechanical pin insertion in the prior art only realizes the pin insertion through a simple driving mechanism and a clamping claw and other structures. The alignment rate between the accessories and the mounting shell is poor, the plug-in efficiency is low, and due to the insufficient alignment accuracy, the accessories are easily damaged during the plug-in process, which reduces the product yield.
[0039] In order to solve the above problems, the present invention provides an automatic inserting machine 100 .
[0040] It should be noted that the accessory in the present invention is a terminal 31 , and in other embodiments, it can also be other structural products to complete the assembly with the mounting shell 30 .
[0041] Please combine Figure 1 , Figure 3 , Figure 4 and Figure 5In one embodiment of the present invention, the automatic inserting machine 100 is used to insert the terminal 31 into the mounting hole 32 of the mounting shell 30. The automatic inserting machine 100 includes a feeding module 1 and a cutting pin module 2. The feeding module 1 includes a feeding track 11 and a feeding drive assembly 12. A feeding cavity 111 extending in a horizontal direction is formed in the feeding track 11. A positioning hole 112 connected to the feeding cavity 111 is opened on the top of the feeding track 11. The feeding drive assembly 12 is used to drive the mounting shell 30 to move along the extension direction of the feeding cavity 111; the cutting pin module 2 includes a cutting module 21, a pin module 22 and a feeding module 23. The cutting module 21 includes a cutting assembly 211 and a first horizontal driving member 212. The feeding module 23 is used to send a material strip 33 carrying the terminal 31 to the cutting assembly 211. The cutting assembly 211 is used to In order to cut the terminal 31 from the material strip 33 and fix the cut terminal 31, the pin module 22 includes a pin pressure rod 221 and a first lifting drive member 222. The pin pressure rod 221 is correspondingly arranged above the positioning hole 112 and is spaced apart from the positioning hole 112 to form a pin space 223; when the mounting shell 30 moves along the extension direction of the feed cavity 111 until its mounting hole 32 corresponds to the positioning hole 112, the first horizontal drive member 212 drives the cutting component 211 to move horizontally to move the cutting component 211 and the terminal 31 fixed on the cutting component 211 into the pin space 223, and the first lifting drive member 222 drives the pin pressure rod 221 to descend vertically, and the terminal 31 located in the pin space 223 is pressed down by the pin pressure rod 221, so that the terminal 31 passes through the positioning hole 112 and is inserted into the mounting hole 32.
[0042] When in use, first put the installation shell 30 into the feeding cavity 111, and the feeding drive component 12 drives the installation shell 30 to move in the feeding cavity 111 to a position where its installation hole 32 is aligned with the positioning hole 112, and then the installation shell 30 stops moving, and the feeding module 23 sends the material strip 33 to the cutting component 211, and the cutting component 211 cuts the terminal 31 from the material strip 33 and fixes the terminal 31, and the first horizontal driving member 212 drives the cutting component 211 to move the terminal 31 to the pin space 223, aligning the terminal 31 with the positioning hole 112, and then the first lifting driving member 222 drives the pin pressing rod 221 to press down, and the terminal on the cutting component 211 The pin 31 is pressed down to pass through the positioning hole 112 and inserted into the mounting hole 32, thereby completing the pin insertion operation, and then the terminal 31 and the mounting shell 30 with the pin inserted are continuously conveyed through the feed cavity 111 until they are conveyed to the discharge end of the feed cavity 111 to complete the discharge. It should be noted that the operation of the feeding module 23 and the cutting assembly 211 can be performed after the mounting hole 32 of the mounting shell 30 is aligned with the positioning hole 112, or the terminal 31 can be cut off in advance and moved to the pin insertion space 223, and the terminal 31 can be directly pressed down and inserted into the mounting hole 32 when the mounting hole 32 of the mounting shell 30 is aligned with the positioning hole 112, thereby improving the plug-in efficiency.
[0043] The technical solution of the present invention adopts the above technical features, and forms a closed feeding cavity 111 in the feeding channel. The mounting shell 30 moves in the feeding channel along the extension direction of the feeding cavity 111, so that the mounting shell 30 is not affected by the external environment, and the positioning accuracy is guaranteed. The feeding cavity 111 has a limiting effect on the mounting shell 30 to prevent the mounting shell 30 from being offset. The position where the positioning hole 112 is opened on the feeding channel is correspondingly provided with a pin module 22, and the pin pressure rod 221 is correspondingly provided above the positioning hole 112. The cutting component 211 cuts the terminal 31 from After the material strip 33 is cut, the terminal 31 is fixed and moved to the pin space 223 below the pin pressure rod 221 under the drive of the first horizontal driving member 212, and the terminal 31 is aligned with the positioning hole 112, and the mounting hole 32 of the mounting shell 30 is also aligned with the positioning hole 112. At this time, the pin pressure rod 221 is driven downward by the first lifting driving member 222 to push the terminal 31 out of the cutting component 211, and pass through the positioning hole 112 all the way down and insert it into the mounting hole 32, so as to realize the connection between the terminal 31 and the mounting hole 32, thereby realizing a fully automatic pin insertion process.
[0044] The present invention fixes the terminal 31 through the cutting component 211, so that the terminal 31 will not be offset after being cut from the material strip 33. At the same time, after the terminal 31 is moved into the pin insertion space 223, it only needs to pass through a positioning hole 112 to achieve the pin insertion operation, thereby reducing the number of processes that the terminal 31 needs to go through. The fewer the processes, the less errors will be generated and the higher the accuracy. At the same time, the mounting shell 30 is also limited by the feed cavity 111, which improves the positioning accuracy of the mounting shell 30. The positioning accuracy of the mounting shell 30 and the terminal 31 are both improved, thereby improving the alignment rate and alignment accuracy of the terminal 31, improving the plug-in efficiency, reducing the damage to the terminal 31, and improving the yield rate. At the same time, the above structure can achieve full-automatic pin insertion, improve the pin insertion efficiency, and reduce the cost.
[0045] Please combine Figures 3 to 6In one embodiment, the cutting assembly 211 includes a fixed knife 213, a movable knife 214 and a second horizontal driving member 215. The fixed knife 213 is provided with a limiting groove 216. The movable knife 214 is spaced apart from the fixed knife 213 to form a cutting gap 217. The feeding module 23 is used to vertically deliver the material strip 33 into the cutting gap 217 so that the terminal 31 carried on the material strip 33 is limited in the limiting groove 216. The second horizontal driving member 215 drives the movable knife 214 to move horizontally toward the fixed knife 213 and abut against the fixed knife 213 to cut the terminal 31 from the material strip 33. A limiting groove 216 is provided on the fixed knife 213. When the terminal 31 on the material strip 33 moves to the cutting assembly 211, a portion of the terminal 31 extends into the limiting groove 216, thereby limiting the terminal 31 in the horizontal direction to prevent the position of the terminal 31 from shifting. However, there is no restriction on the movement of the terminal 31 in the vertical direction, thereby ensuring that the terminal 31 will not shift when fixed on the fixed knife 213, thereby improving the positioning accuracy of the terminal 31.
[0046] Specifically, the second horizontal driving member 215 can be a driving member such as a spring or a motor that can drive the movable knife 214 to move toward or away from the movable knife 214 in the horizontal direction. The movable knife 214 and the fixed knife 213 are normally arranged at an interval. Only when the material belt 33 corresponds to the fixed knife 213, the movable knife 214 moves toward the fixed knife 213.
[0047] Please combine Figure 6 and Fig.10 In one embodiment, the terminal 31 is formed with bent portions 311 on both sides along the horizontal direction, and the limiting groove 216 is adapted to the bent portions 311. In the horizontal direction, the bent portions 311 are pressed against the limiting groove 216 to limit the terminal 31. The bent portions 311 at both ends of the terminal 31 are used to extend into the limiting groove 216, and the side walls of the bent portions 311 along the horizontal direction are pressed against the limiting groove 216, so that the bent portions 311 are embedded in the limiting groove 216, and the bent portions 311 can only move vertically but not horizontally, thereby further limiting and fixing the terminal 31, preventing the terminal 31 from deflecting during the downward movement, and further improving the positioning accuracy of the terminal 31.
[0048] Please combine Figure 4 and Figure 5Furthermore, a bending section 224 adapted to the limiting groove 216 is formed on the side of the pin pressure rod 221 facing the fixed knife 213, and a positioning portion 225 adapted to the top shape of the terminal 31 is provided at the bottom of the pin pressure rod 221. The positioning portion 225 is used to press against the top of the terminal 31 located in the limiting groove 216. The first lifting drive member 222 drives the pin pressure rod 221 to descend so that the bending section 224 extends into the limiting groove 216 and is plugged into the limiting groove 216, so that the pin pressure rod 221 presses the terminal 31 located in the limiting groove 216 down to pass through the positioning hole 112 and be inserted into the mounting hole 32. The bent section 224 of the pin pressure rod 221 is adapted to the limiting groove 216, so that the bent section 224 of the pin pressure rod 221 can extend into the limiting groove 216 and abut against the bent portion 311 of the terminal 31 in the limiting groove 216, so that the terminal 31 is subjected to uniform force at various locations to avoid tilting due to uneven force. At the same time, the positioning portion 225 is adapted to the top of the terminal 31, so that the top of the terminal 31 and the bottom of the pin pressure rod 221 are tightly fitted everywhere, and the force is uniform everywhere, which further avoids the terminal 31 from tilting during the pressing process and further improves the positioning accuracy of the terminal 31.
[0049] Please combine Figure 5 and Figure 6 Furthermore, the shape of the positioning hole 112 is adapted to the shape of the terminal 31, and in the horizontal direction, the terminal 31 is pressed against the hole wall of the positioning hole 112 to limit the terminal 31, the mounting hole 32, the positioning hole 112 and the limiting groove 216 are connected in sequence to form a guide channel for the terminal 31 to move, and the shape of the cross section of the feed cavity 111 is adapted to the shape of the cross section of the mounting shell 30, so that the outer wall of the mounting shell 30 and the inner wall of the feed cavity 111 are in sliding contact and fit.
[0050] The shape of the positioning hole 112 is adapted to the shape of the terminal 31, and the terminal 31 can be further limited when the terminal 31 passes through the positioning hole 112. If the terminal 31 is slightly tilted, the terminal 31 can also be corrected. The guide channel formed by the triple limiting and correction of the mounting hole 32, the positioning hole 112 and the limiting groove 216 can avoid the influence of external factors on the angle of the terminal 31 to the greatest extent during the process of the terminal 31 moving downward from the fixed knife 213, thereby improving the positioning precision and positioning accuracy of the terminal 31, thereby improving the plug-in efficiency of the terminal 31 and the overall product yield.
[0051] In one embodiment, a suction hole 218 is provided on one side of the fixed blade 213 facing the terminal 31, and the cutting module 21 further includes a suction member 219, which is used to evacuate the suction hole 218 to form a negative pressure to absorb the terminal 31 into the limiting groove 216. The suction member 219 evacuates the suction hole 218 to form a negative pressure, and absorbs the terminal 31 onto the fixed blade 213, so that the terminal 31 will not fall or deviate during the process of moving to the pin space 223, thereby improving the positioning accuracy of the terminal 31.
[0052] Please combine Figure 3 , Figure 4 and Fig.10 Specifically, the feed module 23 includes a feed member 231 and a second lifting drive member 232. A plurality of terminals 31 are arranged vertically at intervals on the material belt 33. The second lifting drive member 232 is used to drive the material belt 33 to descend vertically along the feed member 231. The bottom of the feed member 231 forms a cutting space 233 arranged horizontally at intervals with the pin space 223. The first horizontal drive member 212 is used to drive the cutting assembly 211 to move horizontally between the cutting space 233 and the pin space 223. A plurality of terminals 31 are arranged at intervals on the material belt 33. The second lifting drive member 232 drives the material belt 33 to descend step by step, so that each terminal 31 corresponds to the cutting space 233 in sequence. After one terminal 31 is cut off and removed by the fixed knife 213, the material belt 33 only needs to be sent down to cut the next terminal 31, thereby improving the feeding efficiency of the terminal 31.
[0053] Furthermore, the feed module 23 also includes a material belt conveying assembly 234, which is located above the feed piece 231 and is used to convey the material belt 33 to the feed piece 231 to continuously provide the material belt 33, thereby improving the supply efficiency of the terminal 31.
[0054] See also Fig.10 Furthermore, the material strip 33 includes a plurality of accommodating members 331, each accommodating member 331 includes a carrying ring 332 and a connecting portion 333, the carrying ring 332 is annular and encloses a accommodating space for accommodating the terminal 31, the terminal 31 is connected to the carrying member through the connecting portion 333, and is correspondingly arranged in the accommodating space, the movable knife 214 abuts against the fixed knife 213 to cut off the connecting portion 333 to cut the terminal 31 from the material strip 33, and at the same time, the corresponding carrying ring 332 needs to be cut off and discarded to avoid the carrying ring 332 that has cut off the terminal 31 affecting other components, so a waste collection member is provided below the cutting space 233, because a plurality of terminals 31 are provided on the material strip 33, after the corresponding terminal 31 is cut off, the useless part of the material strip 33 for fixing the terminal 31 needs to be cut off, and the cut waste is collected by the waste collection member to prevent the waste from affecting other components.
[0055] Please combine Figure 1 and Figure 7 In one embodiment, the feed track 11 includes an upper shell 113 and a lower shell 114, which are buckled together to form a feed cavity 111. The feed drive assembly 12 is arranged on the side of the feed track 11 away from the cutting pin module 2. A gap 115 connected to the feed cavity 111 is formed between the upper shell 113 and the lower shell 114. The gap 115 extends in the horizontal direction and is located on the side of the feed track 11 facing the cutting pin module 2; the feed drive assembly 12 includes a third horizontal drive member 121, a fourth horizontal drive member 122 and a shift fork 123, and the third horizontal drive member 124 is provided. The fourth horizontal driving member 122 is used to drive the fork 123 to move horizontally in a direction close to the feed track 11, so as to insert the fork 123 into the gap 115 and make the fork 123 abut against the end of the mounting shell 30; the fourth horizontal driving member 122 is also used to drive the fork 123 to move horizontally in a direction away from the feed track 11 to pull the fork 123 out of the gap 115, and the third horizontal driving member 121 is used to drive the fork 123 to move along the extension direction of the feed track 11, so as to drive the mounting shell 30 abutting against the fork 123 to move along the extension direction of the feed cavity 111.
[0056] When the installation shell 30 needs to be moved, the fourth horizontal driving member 122 is used to drive the fork 123 to move in the direction close to the feeding track 11, so that the fork 123 extends into the feeding cavity 111 through the gap 115 and abuts against the end of the installation shell 30, and then the third horizontal driving member 121 drives the fork 123 to move along the extension direction of the feeding cavity 111, so as to drive the installation shell 30 abutting against the fork 123 to move along the extension direction of the feeding cavity 111, thereby realizing the transportation of the installation shell 30. After the transportation is completed, The fork 123 moves in a direction away from the feed track 11 to disengage from the feed cavity 111, and then returns to the starting point to transport the next installation shell 30. For this structure that requires continuous feeding, a rotary conveyor belt is usually used for transportation, but the conveyor belt cannot limit the installation shell 30. Therefore, the above structure can ensure uninterrupted transportation of the installation shell 30 while limiting the installation shell 30 through the upper shell 113 and the lower shell 114, thereby improving the positioning accuracy of the installation shell 30.
[0057] Furthermore, an elastic fixing member 116 is provided at a position corresponding to the positioning hole 112 on the lower shell 114. The elastic fixing member 116 is horizontally arranged, and the extension direction of the elastic fixing member 116 is perpendicular to the extension direction of the feeding channel. The elastic fixing member 116 passes through the lower shell 114 and is used to abut against the mounting shell 30 located at the positioning hole 112. When the mounting hole 32 of the mounting shell 30 corresponds to the positioning hole 112, the elastic fixing member 116 abuts against the outer wall of the mounting shell 30, thereby providing an elastic force perpendicular to the extension direction of the feeding channel to the mounting shell 30. The elastic force pushes the mounting shell 30 against the inner wall of the feeding cavity 111 to prevent the mounting shell 30 from moving, thereby ensuring that the mounting hole 32 is always aligned with the positioning hole 112, and improving the positioning accuracy of the mounting hole 32. When the shift fork 123 pushes the mounting shell 30 to move, the driving force on the mounting shell 30 is greater than the elastic force, and the mounting shell 30 continues to move along the extension direction of the feeding cavity.
[0058] See also Figure 8 In one embodiment, the input end and the output end of the feed track 11 are both provided with a material shifting module 13 and a transfer module 14. The transfer module 14 includes a fifth horizontal driving member 141 and a storage rack 142. A plurality of storage cavities 143 for accommodating the mounting shell 30 are formed at intervals in the storage rack 142. The extension direction of each storage cavity 143 is the same as the extension direction of the feed cavity 111. The fifth horizontal driving member 141 drives the storage rack 142 to move in the horizontal direction so that each storage cavity 143 corresponds to and communicates with the feed cavity 111 respectively. The material shifting module 13 includes a material shifting fork 131. The material shifting fork 131 is used to extend into the storage cavity 143 and shift the mounting shell 30 from the storage cavity 143 to the feed cavity 111. The material shifting fork 131 is also used to extend into the feed cavity 111 and shift the mounting shell 30 from the feed cavity 111 to the storage cavity 143.
[0059] It should be noted that, since the material shifting module 13 located at the output end is used to extend into the material delivery cavity 111 and shift the mounting shell 30 from the material delivery cavity 111 to the storage cavity 143, an escape opening is opened at the top of the material shifting module 13 corresponding to the output end of the material delivery track, and the escape opening is connected to the material delivery cavity so that the material shifting fork 131 of the material shifting module 13 located at the output end can extend into the material delivery cavity and abut against the mounting shell.
[0060] There are multiple storage cavities 143, so that the fifth horizontal driving member 141 can drive multiple mounting shells 30 to the feeding cavity 111 at one time, thereby improving the feeding efficiency, and further improving the plug-in efficiency of the terminal 31 and the mounting shell 30. The multiple storage cavities 143 are arranged at intervals in a direction perpendicular to the extension direction of the feeding cavity 111, so that after the mounting shell 30 in a storage cavity 143 is moved into the feeding cavity 111, it is only necessary to push the storage rack 142 for a distance through the fifth horizontal driving member 141 to move the next mounting shell 30 to the corresponding feeding cavity 111, without the need for re-loading, thereby improving the loading efficiency. At the other end of the feeding track 11, the mounting shell 30 is moved from the feeding cavity 111 to the storage cavity 143. Similarly, the setting of multiple storage cavities 143 can improve the unloading efficiency.
[0061] It should be noted that the above-mentioned first horizontal driving member 212, first horizontal driving member 212, first horizontal driving member 212, first horizontal driving member 212, first horizontal driving member 212, first lifting driving member 222 and second lifting driving member 232 can all adopt conveying members such as cylinders, electric cylinders or ratchet structures in the prior art.
[0062] Please combine Figure 1 , Figure 8 and Fig. 9 In one embodiment, the material shifting module 13 arranged at the input end 117 of the feed track 11 corresponds to the transfer module 14, and the material shifting module 13 arranged at the output end 118 of the feed track 11 corresponds to the feed track 11. The output end 118 of the feed track 11 is also provided with a discharging module 15, and the discharging module 15 includes a clamp 151 and a discharging drive assembly 152. The discharging drive assembly 152 drives the clamp 151 to move in the horizontal direction or to rise and fall in the vertical direction. The clamp 151 is used to clamp the mounting shell 30 stored in the storage cavity 143.
[0063] The material shifting module 13 at the input end 117 is arranged corresponding to the transfer module 14, so that the material shifting fork 131 can shift the installation shell 30 in the storage cavity to the feed cavity 111. The material shifting module 13 at the output end 118 is arranged corresponding to the feed track 11, so that the material shifting fork 131 can shift the installation shell 30 in the feed cavity 111 to the storage cavity 143. The clamping claw 151 directly clamps and removes multiple installation shells in multiple storage cavities 143 in the storage rack 142, so that multiple terminals 31 and installation shells 30 that have been plugged in can be taken out at one time, thereby improving the discharge efficiency.
