Description

Technical Field

[0001] This application relates to the field of electronic component manufacturing equipment technology, and in particular to a fully automatic pin insertion device. Background Technology

[0002] In the manufacturing process of consumer electronics and communication devices, pins need to be inserted into injection molded parts. Some pins are small in size, for example, 0.5mm. 0.5mm, this type of small pin is formed by cutting the unwound pin filament roll. In the existing technology, the injection molded part is placed in the positioning fixture manually. Because the pin filament roll is relatively soft, it needs to be cut into segments of pins by a cutting mechanism first. Then, the pins are inserted into the injection molded part placed in the positioning fixture manually using tools such as tweezers. The production efficiency is low. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a fully automatic pin insertion device capable of automating pin insertion.

[0004] The fully automatic needle insertion device according to an embodiment of this application includes: an unwinding mechanism, a cutting mechanism, a positioning mechanism, and a first translation mechanism.

[0005] Unwinding mechanism, used for unwinding the filament; A cutting mechanism, disposed on one side of the unwinding mechanism, includes a cutting drive assembly, a first cutting assembly, and a second cutting assembly. The first cutting assembly includes a first movable seat, a first punching block, and a mating block. The first punching block is disposed on the first movable seat and movably disposed on the mating block on the side opposite to the unwinding mechanism. The mating block is fixedly disposed and has a mating hole for passing filaments. The mating hole has an inlet and an outlet along the filament conveying direction. The second cutting assembly includes a second movable seat and a second punching block. The second punching block is movably disposed on the side of the mating block away from the unwinding mechanism and opposite to the first punching block, located on the second movable seat. The cutting drive assembly drives the first movable seat and the second movable seat to move sequentially toward each other. The first punching block moves to the side of the discharge port first, and the second punching block moves to the discharge port to cooperate with the discharge port to cut the end of the filament and form a pressure needle. The second punching block then clamps the pressure needle with the first punching block. A positioning mechanism for positioning injection molded parts is provided on the side of the mating block away from the cutting mechanism. The pressure pin held by the first punching block and the second punching block can be inserted into the injection molded parts positioned by the positioning mechanism.

The cutting drive assembly drives the first movable seat to move closer to the second movable seat; the first movable seat drives the first punching block to move closer to the second punching block and to the side of the outlet, ensuring the first punching block does not obstruct the outlet. Subsequently, the cutting drive assembly drives the second movable seat to move closer to the first movable seat; the second movable seat drives the second punching block to move closer to the first punching block; the second punching block passes through the outlet and, in conjunction with the outlet, cuts the end of the filament, causing the portion of the filament exiting the outlet to separate from the filament and form a needle.

[0024] The following is combined with Figures 1 to 10 This application describes a fully automated needle insertion device according to embodiments thereof.

[0025] Reference Figures 1 to 5 The fully automatic needle insertion device according to an embodiment of this application includes: an unwinding mechanism 100, a cutting mechanism 200, a positioning mechanism 300, and a first translation mechanism 400.

[0026] Unwinding mechanism 100, used for unwinding the filament 10; The cutting mechanism 200 is disposed on one side of the unwinding mechanism 100 and includes a cutting drive assembly 210, a first cutting assembly 220 and a second cutting assembly 230; The first cutting assembly 220 includes a first movable seat 221, a first punching block 222, and a mating block 225. The first punching block 222 is disposed on the first movable seat 221. The first punching block 222 is movably disposed on the mating block 225 on the side opposite to the unwinding mechanism 100. The mating block 225 is fixedly disposed. The mating block 225 has a mating hole for the passage of the wire 10. The mating hole has an inlet 225a and an outlet 225b along the conveying direction of the wire 10. The second cutting assembly 230 includes a second movable seat 231 and a second punching block 232. The second punching block 232 is disposed on the second movable seat 231 and is movably disposed on the side of the mating block 225 away from the unwinding mechanism 100, and is disposed opposite to the first punching block 222. The cutting drive assembly 210 drives the first movable seat 221 and the second movable seat 231 to move in a direction closer to each other. The first punching block 222 moves to the side of the discharge port 225b first, and the second punching block 232 moves to the discharge port 225b to cooperate with the discharge port 225b to cut the end of the wire 10 to form a pressure needle. The second punching block 232 then clamps the pressure needle with the first punching block 222. The positioning mechanism 300 is used to position the injection molded part. It is set on the side of the mating block 225 away from the cutting mechanism 200. The pressure needle held by the first punching block 222 and the second punching block 232 can be inserted into the injection molded part positioned by the positioning mechanism 300. The first translation mechanism 400 drives the cutting mechanism 200 and / or the positioning mechanism 300 to move the cutting mechanism 200 and the positioning mechanism 300 closer to each other so that the pressure needles held by the first punching block 222 and the second punching block 232 are inserted into the injection molded part positioned by the positioning mechanism 300.

[0027] An injection molded part is placed inside the positioning mechanism 300. The unwinding mechanism 100 unwinds the filament 10 to the cutting mechanism 200. The filament 10 first passes through the inlet 225a of the mating block 225 into the mating hole, and then exits through the outlet 225b of the mating block 225. The portion of the filament 10 that exits through the outlet 225b passes between the first punching block 222 and the second punching block 232. (Refer to...) Figure 3 and Figure 4 The cutting drive assembly 210 drives the first movable seat 221 to move closer to the second movable seat 231. The first movable seat 221 drives the first punching block 222 to move closer to the second punching block 232 and to the side of the discharge port 225b. The first punching block 222 will not block the discharge port 225b. Subsequently, referring to... Figure 5 and Figure 6The cutting drive assembly 210 drives the second movable seat 231 to move closer to the first movable seat 221. The second movable seat 231 drives the second punching block 232 to move closer to the first punching block 222. The second punching block 232 passes through the discharge port 225b and cuts the end of the filament 10 with the discharge port 225b, so that the part of the filament 10 that passes through the discharge port 225b separates from the filament 10 to form a pressure needle. Since the first punching block 222 is located beside the discharge port 225b, the second punching block 232 will cooperate with the first punching block 222 to clamp the pressure needle. Then, the first translation mechanism 400 drives the cutting mechanism 200 and the positioning mechanism 300 to move closer to each other. The pressure needle held by the first punching block 222 and the second punching block 232 moves closer to the injection molded part at the positioning mechanism 300, so that the pressure needle is inserted into the injection molded part, thereby realizing automated pressure needle insertion.

[0028] It is also understandable that after the current injection molding process of inserting the pins is completed, the first punching block 222 and the second punching block 232 are reset, and the unwinding mechanism 100 unwinds the filament 10 so that the end of the filament 10 re-exits from the discharge port 225b, so as to facilitate the next punching.

[0029] It is also understandable that the filament 10 is relatively small and flexible. Therefore, the second cutting block 232, in conjunction with the outlet 225b, first cuts the filament 10 to form a pressure needle, and then the first cutting block 222 clamps the pressure needle, making it less likely to bend and fail to insert during the injection molding process. Specifically, the portion of the pressure needle held by the first cutting block 222 and the second cutting block 232 is greater than half the length of the pressure needle to ensure support for the pressure needle.

[0030] Specifically, material 10 is a pin filament roll, and the pressing needle is a pin needle.

[0031] Reference Figure 7According to some embodiments of this application, the cutting drive assembly 210 includes a cutting driver 211 and a mating frame 212, the mating frame 212 having a first mating surface 212a and a second mating surface 212b; the first cutting assembly 220 further includes a first mating wheel 223, the first mating wheel 223 being disposed on a first movable seat 221, the first mating wheel 223 being slidably mated with the first mating surface 212a to drive the first movable seat 221 to move toward the second movable seat 231; the second cutting assembly 230 further includes a second mating wheel 233, the first... Two mating wheels 233 are disposed on the second movable seat 231. The second mating wheels 233 can slide and engage with the second mating surface 212b to drive the second movable seat 231 to move toward the first movable seat 221. The cutting driver 211 drives the connecting mating frame 212 to move relative to the first mating wheel 223 and the second mating wheel 233. Along the moving direction of the mating frame 212, the distance between the first mating surface 212a and the first mating wheel 223 is less than the distance between the second mating surface 212b and the second mating wheel 233.

[0032] It is understandable that the mating frame 212 has a fork-shaped structure, with the first mating wheel 223 and the second mating wheel 233 located inside the mating frame 212. The mating frame 212 forms a first mating surface 212a and a second mating surface 212b. This arrangement ensures that the mating frame 212 slides with the first mating wheel 223 and the second mating wheel 233, while also ensuring that the wire 10 can pass through the inside of the mating frame 212 to penetrate between the first punching block 222 and the second punching block 232. The cutting driver 211 drives the mating frame 212 to rise. Since the distance between the first mating surface 212a and the first mating wheel 223 is less than the distance between the second mating surface 212b and the second mating wheel 233, the first mating wheel 223 will first slide and engage with the first mating surface 212a. The first mating wheel 223 drives the first movable seat 221 to move closer to the second movable seat 231. As the mating frame 212 continues to rise, the second mating surface 212b slides and engages with the second mating wheel 233. The second sliding wheel drives the second movable seat 231 to move closer to the first movable seat 221, thereby enabling the first movable seat 221 and the second movable seat 231 to move sequentially.

[0033] Specifically, both the first mating surface 212a and the second mating surface 212b include an inclined surface and a straight surface. When the inclined surface slides with the first mating wheel 223 / second mating wheel 233, it can push the first mating wheel 223 / second mating wheel 233 to move. When the straight surface slides with the first mating wheel 223 / second mating wheel 233, it can limit the first mating wheel 223 / second mating wheel 233 to the current position, so that the first punching block 222 / second punching block 232 is kept in the current position.

[0034] According to some embodiments of this application, the cutting mechanism 200 further includes an elastic component (not shown in the figure), which connects the first movable seat 221 and the second movable seat 231 and provides an elastic force that moves the first movable seat 221 and the second movable seat 231 away from each other.

[0035] Understandably, the elastic component compresses when the first movable seat 221 and the second movable seat 231 approach each other. After the pressure needle is inserted into the injection molded part, the cutting driver 211 drives the mating frame 212 to descend, and the elastic component extends to push the first movable seat 221 and the second movable seat 231 away from each other, so that the first movable seat 221 and the second movable seat 231 can be reset.

[0036] In some other embodiments, a cylinder may be added to push the first movable seat 221 and the second movable seat 231 away from each other in order to achieve resetting.

[0037] Reference Figures 4 to 6 According to some embodiments of this application, the first cutting component 220 further includes a first embossing block 224, which is disposed on the first movable seat 221 and located on the side of the first punching block 222 near the unwinding mechanism 100; the second cutting component 230 includes a second embossing block 234, which is disposed on the second movable seat 231 and located on the side of the second punching block 232 near the unwinding mechanism 100; when the first movable seat 221 and the second movable seat 231 approach each other, the first embossing block 224 and the second embossing block 234 cooperate to punch the wire 10, so that the wire 10 forms a groove 11a.

[0038] It is understandable that when the wire 10 passes between the first punching block 222 and the second punching block 232, it will first pass between the first embossing block 224 and the second embossing block 234. When the first movable seat 221 and the second movable seat 231 approach each other, the first embossing block 224 and the second embossing block 234 approach each other to form a groove 11a on the wire 10. As a result, a groove 11a will also be formed on the pressure needle. The pressure needle will pass through the mounting hole of the injection molded part. A locking block can be formed in the mounting hole. After the pressure needle is inserted into the mounting hole, the locking block can cooperate with the groove 11a to make the connection between the pressure needle inserted into the mounting hole and the injection molded part stable, and to ensure that the insertion depth of the pressure needle relative to the injection molded part is stable each time.

[0039] Reference Figure 4 and Figure 6According to some embodiments of this application, the first embossing block 224 has a first limiting tooth 2241 and a first embossing tooth 2242. The first limiting tooth 2241 has a first limiting groove 2241a. The second embossing block 234 has a second embossing tooth 2342, which is disposed opposite to the first embossing tooth 2242. During the process of the first movable seat 221 and the second movable seat 231 moving toward each other, the wire 10 is first inserted into the first limiting groove 2241a, and then the first embossing tooth 2242 and the second embossing tooth 2342 cooperate to punch the wire 10, so that the wire 10 forms a slot 11a.

[0040] Understandably, referring to Figure 4 When the first movable seat 221 and the second movable seat 231 approach each other, the first movable seat 221 will move towards the second movable seat 231 first. The first movable seat 221 will first drive the first embossing block 224 towards the second embossing block 234. The first limiting tooth 2241 is closer to the wire 10 than the first embossing tooth 2242. The first limiting groove 2241a passes through the first limiting tooth 2241 along the conveying direction of the wire 10, and the opening of the first limiting groove 2241a faces the direction of the second embossing block 234. Thus, as the first embossing block 224 approaches the second embossing block 234, the wire 10 first enters and passes through the first limiting groove 2241a. The first limiting groove 2241a plays a limiting role on the wire 10. Then, the first embossing tooth 2242 will abut against the wire 10. After the first movable seat 221 moves into place, refer to Figure 6 The second movable seat 231 moves closer to the first movable seat 221. The second movable seat 231 then drives the second embossing block 234 to move closer to the first embossing block 224. The second embossing block 234 abuts against the wire 10. As the second movable seat 231 continues to move closer to the first movable seat 221, the second embossing block 234 cooperates with the first embossing block 224 to punch the upper end face of the wire 10 in the horizontal direction, so as to punch the groove 11a out of the upper end face of the wire 10.

[0041] It is also understandable that the first embossing block 224 and the second embossing block 234 are arranged opposite each other. During the process of the first embossing block 224 and the second embossing block 234 working together to punch the wire 10, the first embossing block 224 and the second embossing block 234 abut against the opposite sides of the wire 10, and play a supporting role in the process of punching the wire 10.

[0042] Reference Figure 4 and Figure 6 According to some embodiments of this application, the second embossing tooth 2342 further includes a second limiting tooth 2341, which is offset from the first limiting tooth 2241. The second limiting tooth 2341 has a second limiting groove 2341a, which is used to limit the material wire 10.

[0043] Understandably, the second limiting tooth 2341 is closer to the filament 10 than the second embossing tooth 2342. The second limiting groove 2341a extends through the second limiting tooth 2341 along the conveying direction of the filament 10, and the opening of the second limiting groove 2341a faces the first embossing block 224. Therefore, as the second embossing block 234 approaches the first embossing block 224, the filament 10 first enters and passes through the second limiting groove 2341a, and the second limiting groove 2341a acts on the filament 10. The second limiting groove 2341a, with its opening facing the first embossing block 224 and the first limiting groove 2241a, faces the second embossing block 234. The second limiting groove 2341a, in conjunction with the first limiting groove 2241a, restricts the swaying of the wire 10, ensuring stable and precise punching of the subsequent first embossing tooth 2242 and second embossing tooth 2342. Furthermore, the first limiting tooth 2241 and the second limiting tooth 2341 are staggered to avoid interference. After the wire 10 enters the second limiting groove 2341a, the second embossing tooth 2342 will abut against the wire 10.

[0044] Specifically, along the conveying direction of the filament 10, there are multiple first embossing teeth 2242 and second embossing teeth 2342, and they are arranged one to one opposite each other.

[0045] Specifically, along the conveying direction of the filament 10, there are two first limit blocks and two second limit blocks, multiple first embossing teeth 2242 are arranged between the two first limit blocks, and multiple second embossing teeth 2342 are arranged between the two second limit blocks.

[0046] Reference Figure 2 and Figure 8 According to some embodiments of this application, a wire pressing mechanism 500 is also included. The wire pressing mechanism 500 is disposed between the cutting mechanism 200 and the unwinding mechanism 100. The wire pressing mechanism 500 includes a wire pressing driver 510, a fixed pressure plate 520 and a movable pressure plate 530. The movable pressure plate 530 is located on one side of the fixed pressure plate 520. A guide groove 521 is provided on the side of the fixed pressure plate 520 near the movable pressure plate 530. The guide groove 521 is used for the passage of the wire 10. The wire pressing driver 510 drives the movable pressure plate 530 to move closer to the fixed pressure plate 520.

[0047] Understandably, the wire 10 will pass through the wire pressing mechanism 500 before entering the cutting mechanism 200. The guide groove 521 of the fixed pressure plate 520 passes through the pressure plate along the transmission direction of the wire 10. The guide groove 521 is located on the transmission path of the wire 10, and the wire 10 will continue to pass through the guide groove 521. The opening of the guide groove 521 faces the movable pressure plate 530. Before the cutting drive assembly 210 drives the first movable seat 221 and the second movable seat 231 to approach each other, the wire pressing driver 510 drives the movable pressure plate 530 to rise. The movable pressure plate 530 is located on the lower side of the fixed pressure plate 520, and the upper side of the movable pressure plate 530 abuts against the lower side of the fixed pressure plate 520. The movable pressure plate 530 covers the opening of the guide groove 521. The movable pressure plate 530 clamps the wire 10 with the groove wall of the guide groove 521. With this configuration, in the subsequent process of the first embossing block 224 and the second embossing block 234 punching the wire 10, and in the process of the second punching block 232 cutting the wire 10 with the discharge port 225b, the wire 10 can be prevented from swaying, so as to ensure the stability of the punching or cutting process of the wire 10.

[0048] Specifically, the first translation mechanism 400 drives the cutting mechanism 200. With this configuration, since the fixed pressure plate 520 and the movable pressure plate 530 hold the wire 10, as the cutting mechanism 200 approaches the positioning mechanism 300, the fixed pressure plate 520 and the movable pressure plate 530 will pull the wire 10 toward the positioning mechanism 300, so that the winding mechanism automatically unwinds the wire 10. After the insertion of the pressure needle is completed, the fixed pressure plate 520 and the movable pressure plate 530 move away from each other to cancel the fixing of the wire 10. As the cutting mechanism 200 retracts away from the positioning mechanism 300, the cutting mechanism 200 will retract relative to the wire 10, and the wire 10 will be stretched forward relative to the cutting mechanism 200. The mating block 225 will retract relative to the wire 10, and the end of the wire 10 will re-exit the outlet 225b.

[0049] Reference Figure 9 According to some embodiments of this application, it also includes a second translation mechanism 600 and a lifting mechanism 700, which respectively drive the positioning mechanism 300, and the driving directions of the second translation mechanism 600 and the first translation mechanism 400 are perpendicular to each other.

[0050] It is understandable that the injection molded part has multiple mounting holes with parallel extension directions. Through the cooperation of the second translation mechanism 600 and the lifting mechanism 700, the cutting mechanism 200 can be aligned with any one of the mounting holes of the injection molded part, thereby realizing the insertion of pressure pins into the multiple mounting holes of the injection molded part.

[0051] Specifically, the first translation mechanism 400, the second translation mechanism 600, and the lifting mechanism 700 all include a lead screw module.

[0052] Reference Figure 10 According to some embodiments of this application, the positioning mechanism 300 includes a positioning seat 310, a first positioning block 320, a first positioning driver 330, a second positioning block 340, and a second positioning driver 350. The positioning seat 310 is provided with a first fixing block 311, a second fixing block 312, a third fixing block 313, and a fourth fixing block 314. The first fixing block 311 and the second fixing block 312 cooperate to limit the front and rear sides of the lower end of the injection molded part. The third fixing block 313 is disposed opposite to the first positioning block 320. The first positioning driver 330 drives and connects to the first positioning block 320 to drive the first positioning block 320 closer to the third fixing block 313 to cooperate to limit the front and rear sides of the upper end of the injection molded part. The fourth fixing block 314 is disposed opposite to the second positioning block 340. The second positioning driver 350 drives and connects to the second positioning block 340 to drive the second positioning block 340 closer to the fourth fixing block 314 to cooperate to limit the left and right sides of the injection molded part.

[0053] Understandably, the injection molded part is placed on the positioning seat 310, with its lower end positioned between the first fixing block 311 and the second fixing block 312. The injection molded part is pre-positioned by the first fixing block 311 and the second fixing block 312. Furthermore, the third fixing block 313 abuts against the front side of the upper end of the injection molded part, and the fourth fixing block 314 abuts against the left side of the upper end of the injection molded part. The third fixing block 313 and the fourth fixing block 314 provide auxiliary support for the injection molded part. Subsequently, the first positioning driver 330 drives the first positioning block 320 closer to the third fixing block 313, and the first positioning block 320, in conjunction with the third fixing block 313, limits the front and rear sides of the upper end of the injection molded part. The second positioning driver 350 drives the second positioning block 340 closer to the fourth fixing block 314, and the second positioning block 340, in conjunction with the fourth fixing block 314, limits the left and right sides of the injection molded part.

[0054] Reference Figure 1 According to some embodiments of this application, a handling mechanism 800 is also included, which is used to transfer injection molded parts relative to the positioning mechanism 300.

[0055] Understandably, the conveying mechanism 800 can load the injection molded part with the needle to be inserted to the positioning mechanism 300, and can unload the injection molded part with the needle already inserted from the positioning mechanism 300.

[0056] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
