Description

Technical Field

[0001] This invention relates to the field of automated assembly, and more specifically to a pin assembly device. Background Technology

[0002] Pins, also called pins, are metallic materials used in connectors to transmit electrical signals. During use, pins are assembled on the connector, and electrical connections are established through pin insertion to transmit electrical signals.

[0003] When installing pins onto connectors, the connectors are typically made of plastic, while the pins are made of conductive metals or alloys such as copper, silver, or gold. Currently, methods for installing pins onto connectors include injection molding to encapsulate the pins or pressing the pins into the mounting holes on the connector. In the pressing-in method, to ensure accurate insertion, the connector needs to be positioned after receiving the material so that the mounting hole aligns with the pin. However, existing carriers require manual removal of the connector from the carrier and placement into a feeding device, or manual collection of the assembled connector, leading to increased labor costs and low efficiency. Therefore, a pin assembly device is needed to automatically complete the assembly and then deliver the connector. Summary of the Invention

The carrier is provided with a receiving position. The connector on the first feeding component is fed into the receiving position.

[0009] The assembly unit includes a displacement drive unit and a nozzle unit. Driven by the displacement drive unit, the nozzle unit moves between the receiving position and the second feeding assembly, so that the nozzle unit grabs the pin on the second feeding assembly and transfers it above the receiving position, and finally inserts the pin into the connector.

[0010] The vehicle includes a receiving unit and a positioning unit. Driven by a drive unit, the receiving unit and / or the positioning unit perform closing or unfolding actions. When the receiving unit and the positioning unit close, the receiving unit and the positioning unit are spliced ​​together to form a receiving position.

[0011] The assembly assembly also includes a blanking section located below the receiving position. When the receiving unit and the positioning unit are unfolded, the connector with the pins inserted falls into the blanking section.

[0012] Preferably, the second feeding assembly includes a feeding unit and a picking unit, and the feeding unit is provided with a unloading station; the feeding unit is driven by a vibration drive unit, which causes the pins in the feeding unit to be fed from the unloading station into the picking unit.

[0017] Preferably, a material receiving groove is provided on the top surface of the receiving unit, and a positioning block is provided on the first pushing block; when the receiving unit and the positioning unit are closed, the positioning block extends into the material receiving groove, so that the positioning block and the material receiving groove form a material receiving position.

[0018] Preferably, the receiving unit has a feeding mounting groove located directly below it; when the receiving unit and the positioning unit are closed, the feeding mounting groove and the positioning unit form the mounting opening of the feeding part; and when the receiving unit and the positioning unit are unfolded, the receiving unit and the positioning unit move away from the feeding part, causing the connector to fall into the feeding part.

[0019] Preferably, the feeding part includes a first feeding channel and a second feeding channel, one end of the first feeding channel extends into the mounting opening, and the other end of the first feeding channel is connected to the second feeding channel.

[0020] Preferably, the unloading section is provided with a gradually downward sloping ramp, and the connector slides out of the pin assembly device from the unloading section along the ramp.

[0066] Terms involving attachment, connection, etc. (e.g., “connection” and “attachment”) refer to the relationship in which these structures are directly or indirectly fixed or attached to each other through an intermediate structure, and to the relationship of movable or rigid attachment, unless otherwise explicitly stated.

[0067] According to one embodiment of the present invention, Figure 1-15 As can be seen from the diagram, a pin assembly device includes a first feeding assembly 1, a second feeding assembly 2, and an assembly assembly 3. The first feeding assembly 1 is used to transport connectors, the second feeding assembly 2 is used to transport pins, and the assembly assembly 3 is used to assemble the pins onto the connectors. The first feeding assembly 1 and the second feeding assembly 2 are located on opposite sides of the assembly assembly 3. The assembly assembly 3 includes a carrier 33 and an assembly part 35. The carrier 33 has a receiving position, and the connectors from the first feeding assembly 1 are fed into the receiving position.

[0068] The assembly unit 35 includes a displacement drive unit 351 and a suction unit 354. Driven by the displacement drive unit 351, the suction unit 354 moves between the receiving position and the second feeding assembly 2, so that the suction unit 354 grabs the pin on the second feeding assembly 2 and transfers it above the receiving position, and finally inserts the pin into the connector.

[0069] The carrier 33 includes a receiving unit 331 and a positioning unit 332. Driven by a drive unit 32, the receiving unit 331 and / or the positioning unit 332 perform closing or unfolding actions. The receiving unit 331 and the positioning unit 332 are provided with slots. When the receiving unit 331 and the positioning unit 332 are closed, the slots on the receiving unit 331 and the positioning unit 332 are spliced ​​to form a material receiving position. The drive unit 32 is used to drive the receiving unit 331 and / or the positioning unit 332.

[0070] In a preferred embodiment, the driving unit 32 drives either or both of the receiving unit 331 and the positioning unit 332, causing the receiving unit 331 and the positioning unit 332 to close or open. When the receiving unit 331 and the positioning unit 332 close, the workpiece is placed on the receiving position formed by the receiving unit 331 and the positioning unit 332, wherein the workpiece is a connector and the pins are assembled on the connector on the receiving position.

[0071] Specifically, the receiving unit 331 and the positioning unit 332 are connected by a gear 312 and a rack and pinion drive. The racks are respectively mounted on the receiving unit 331 and the positioning unit 332, and the receiving unit 331 and the positioning unit 332 are located on both sides of the gear 312, so that the racks on the receiving unit 331 and the positioning unit 332 are respectively located on both sides of the gear 312. Any component of the receiving unit 331 and the positioning unit 332 is driven by the driving unit 32 and, under the transmission of the gear 312, causes the receiving unit 331 and the positioning unit 332 to perform closing or unfolding actions in opposite directions. In this solution, when the receiving unit 331 is driven by the driving unit 32 to move linearly, the first rack 3315 on the receiving unit 331 drives the gear 312 to rotate, so that the second rack 3325 on the positioning unit 332 moves in the opposite direction to the movement of the first rack 3315 under the drive of the gear 312, so as to realize the closing or unfolding of the receiving unit 331 and the positioning unit 332.

[0072] The pins and connectors are automatically assembled on the carrier 33 of the assembly component 3. The carrier 33 is designed as a half-piece, which separates the receiving unit 331 and the positioning unit 332 on the carrier 33. The assembled connector falls into the unloading part 36 through the gap created by the separation of the receiving unit 331 and the positioning unit 332 by its own weight, thus completing the automated assembly. By automatically unloading the connector, the gripping structure is simplified, the manufacturing cost is saved, and the footprint of the pin assembly device is reduced, making the whole structure more compact.

[0073] Furthermore, the positioning unit 332 includes a first push block 3321 and a second push block 3322. A slide rod 33212 is installed on the side of the first push block 3321. The second push block 3322 is slidably connected to the slide rod 33212. One end of the slide rod 33212 is connected to the first push block 3321, and the other end of the slide rod 33212 extends outward to form a stop, which restricts the positional relationship between the first push block 3321 and the second push block 3322. The positioning unit 332 also includes a push plate 3323. The second push block 3322 is installed on the push plate 3323, and the slide rod 33212 is slidably connected to the push plate 3323.

[0074] The second rack 3325 is mounted on the first push block 3321, so that there is a time difference between the movement of the first push block 3321 and the second push block 3322. Specifically, the time difference between the movement of the first push block 3321 and the second push block 3322 is the time required for the first push block 3321 to slide along the slide bar 33212. The first push block 3321 and the second push block 3322 are provided with partial structures that constitute the material receiving position. Thus, under the drive of the drive unit 32, the first push block 3321 and the second push block 3322 successively close or unfold with the receiving unit 331.

[0075] More specifically, the first push block 3321 and the receiving unit 331 are spliced ​​together to form the main structure of the carrier; a material receiving groove 3312 is provided on the top surface of the receiving unit 331, and the material receiving groove 3312 extends to one side of the receiving unit 331 to form an opening. The first push block 3321 is close to the side of the opening on the receiving unit 331, and the material receiving groove 3312 forms a closed workpiece receiving groove by attaching the first push block 3321 to the opening.

[0076] The first push block 3321 has a first clearance groove 33213, and the receiving unit 331 has a second clearance groove 3311. The first clearance groove 33213 and the second clearance groove 3311 are connected in a cooperative manner. When the first push block 3321 and the receiving unit 331 are closed, the first clearance groove 33213 and the second clearance groove 3311 are connected in a cooperative manner, thereby making the first push block 3321 and the receiving unit 331 form a rectangular structure.

[0077] The first push block 3321 is provided with a positioning block 33211. When the receiving unit 331 and the positioning unit 332 are closed, the positioning block 33211 extends into the receiving groove 3312, so that the positioning block 33211 and the receiving groove 3312 form the side wall of the receiving position. At the same time, the second push block 3322 is located above the positioning block 33211, so that when closed, the second push block 3322 is pressed on the receiving position. The positioning block 33211 and the receiving groove 3312 restrict the horizontal position of the workpiece, and the second push block 3322 restricts the vertical position of the workpiece to ensure that the workpiece is confined within the receiving position. This avoids the workpiece from shifting its position after being subjected to force during the assembly process, so that the pin is accurately inserted into the mounting hole of the connector to improve the assembly accuracy.

[0078] Meanwhile, a pin groove 33121 is provided on the receiving groove 3312, which extends through the upper and lower surfaces. The pin groove 33121 extends along the movement direction of the receiving unit 331 to one side of the receiving unit 331 and forms an opening. When the receiving unit 331 and the positioning unit 332 are unfolded, the PIN pins are released from the opening along the pin groove 33121. As the receiving unit 331 and the positioning unit 332 move away from each other, a gap is formed between them so that the connector to be assembled can be unloaded from the gap. The PIN pins are released from the pin groove 33121 so that the connector is separated from the pin assembly device, which facilitates the unloading of the connector.

[0079] The top surface of the receiving unit 331 is provided with a protruding stop block 3314, which is used to block the second push block 3322. The stop block 3314 is located on the outside of the material receiving groove 3312; and the stop block 3314 is located on the other side opposite to the opening on the material receiving groove 3312.

[0080] During the closing action of the receiving unit 331 and the positioning unit 332, the first push block 3321 drives the second push block 3322 to move. When the second push block 3322 abuts against the stop block 3314, the second push block 3322 slides relative to the first push block 3321, so that the second push block 3322 moves to the top of the receiving groove 3312 to first restrict the vertical position of the connector. Then the positioning block 33211 extends into the receiving groove 3312 to adjust the horizontal position of the connector, thus completing the adjustment action of the connector position.

[0081] In a preferred embodiment, a limiting block 3313 is provided on the periphery of the receiving groove 3312. The limiting block 3313 includes at least a positioning section 33131 and a stop section 33132. The positioning block 33211, the positioning section 33131, and the stop section 33132 cooperate to form a limiting sidewall of the receiving position. Specifically, the positioning section 33131 and the stop section 33132 are integrally formed, and the positioning section 33131 and the stop section 33132 form an L-shape, so that when the connector is fed into the receiving groove 3312, the positioning section 33131 and the stop section 33132 perform preliminary positioning of the connector, and then the positioning block 33211 is used to further position the connector.

[0082] The positioning block 33211 extends outward to form a retaining end 332111. The side of the positioning block 33211 and the retaining end 332111 are correspondingly arranged with the positioning section 33131 and the stop section 33132. The four sides of the connector are limited by the side of the positioning block 332111, the retaining end 332111, the positioning section 33131, and the stop section 33132. A guide bevel is provided at the end of the retaining end 332111 away from the positioning block 33211. During the closing process of the positioning unit 332, the connector is pushed by the guide bevel, pushing the connector that is not in place toward the stop section 33132; specifically, during the feeding process, the connector is fed into the receiving groove 3312 from the extension direction of the positioning section 33131. It is difficult to ensure the position of the connector in the receiving groove 3312, which makes it difficult for the connector to contact the stop section 33132. The connector is pushed by the stop end 332111 to ensure the accuracy of the connector in the pin assembly device.

[0083] Furthermore, the positioning block 33211 has a slot 332112 relative to the material stop end 332111. When the receiving unit 331 and the positioning unit 332 are closed, the stop section 33132 extends into the slot 332112. A friction block 3316 is provided on the upper surface of the limiting block 3313. The second push block 3322 is in contact with the friction block 3316. When the receiving unit 331 and the positioning unit 332 perform the unfolding action, the friction between the second push block 3322 and the friction block 3316 causes the positioning block 33211 to slide relative to the second push block 3322 and be pushed out of the material receiving groove 3312. Then, the first push block 3321 pulls the second push block 3322 away from the receiving unit 331.

[0084] Furthermore, the second push block 3322 includes an extension block 33221 and a clearance mounting hole 33222 formed on the extension block 33221. Part of the extension block 33221 covers the friction block 3316 to increase friction. When the receiving unit 331 and the positioning unit 332 are closed, the clearance mounting hole 33222 is located directly above the receiving position so that the pin can pass through the clearance mounting hole 33222 and be inserted into the connector. More specifically, the clearance mounting hole 33222 extends to one side of the extension block 33221 so that when the receiving unit 331 and the positioning unit 332 are unfolded, the pin can be ejected from the clearance mounting hole 33222 and discharged.

[0085] In a preferred embodiment, the pin assembly device further includes a base plate 31, a gear 312 connected to the base plate 31, and a guide portion 34 mounted on the base plate 31. The guide portion 34 is used to limit the movement direction of the carrier 33. Specifically, the guide portion 34 is disposed on both sides of the carrier 33. The outer side walls of the receiving unit 331 and the first push block 3321 are provided with slide rails that cooperate with the guide portion 34. The guide portion 34 is provided with a sliding groove, so that the slide rails on the receiving unit 331 and the first push block 3321 respectively extend into the sliding grooves of the corresponding guide portions 34 on both sides, so that the sliding direction of the receiving unit 331 and the first push block 3321 is limited by the guide portions 34 on both sides and their mutual abutment. At the same time, a guide rod 311 is also mounted on the base plate 31. The guide rod 311 is slidably connected to the push plate 3323. The guide rod 311 limits the sliding direction of the push plate 3323, thereby limiting the sliding direction of the entire positioning unit 332.

[0086] The receiving unit 331 and the positioning unit 332 are connected by a gear 312 and a rack and pinion drive. The rack and pinion are respectively installed on the receiving unit 331 and the positioning unit 332. The receiving unit 331 and the positioning unit 332 are located on both sides of the gear 312. Any component of the receiving unit 331 and the positioning unit 332 is driven by the driving unit 32 and under the transmission of the gear 312, so that the receiving unit 331 and the positioning unit 332 perform closing or unfolding actions in opposite directions.

[0087] Assembly component 3 also includes a feeding section 36, which is located below the receiving position. After assembly is completed, the receiving unit 331 and the positioning unit 332 unfold, causing the receiving unit 331 to move relative to the connector, thereby exposing the feeding section 36 below the receiving unit 331 and the positioning unit 332. Then, the connector that was originally placed on the receiving unit 331 falls onto the feeding section 36 and is sent out from the pin assembly device along the feeding section 36, completing the automatic assembly.

[0088] The second feeding assembly 2 includes a feeding unit 21 and a picking unit 22. The feeding unit 21 is provided with a unloading station. Under the action of a vibration drive unit 212, the pins in the feeding unit 21 are fed from the unloading station into the picking unit 22.

[0089] The second feeding assembly 2 is provided with a feeding station, and the suction unit 354 moves back and forth between the feeding station and the receiving station under the drive of the displacement driving unit 351.

[0090] The material handling unit 22 includes a material receiving block 222 and a cylinder 221 that drives the material receiving block 222. Under the drive of the cylinder 221, the material receiving block 222 moves back and forth between the loading station and the unloading station of the loading unit 21.

[0091] The material receiving block 222 is provided with a positioning groove, which includes a first positioning groove 2221 and a second positioning groove 2222. The first positioning groove 2221 and the second positioning groove 2222 are connected to form a positioning groove. The part of the pin is inserted into the positioning groove, thereby limiting the pin in the material receiving block 222.

[0092] The assembly part 35 also includes a base 352, which is mounted on the power output end of the displacement drive unit 351. A vertical drive unit 353 is mounted on the base 352, and a suction unit 354 is mounted on the power output end of the vertical drive unit 353. The vertical drive unit 353 drives the suction unit 354 to grab the pin and move it vertically upward from the positioning groove.

[0093] A material receiving groove 3312 is provided on the top surface of the receiving unit 331, and a positioning block 33211 is provided on the first push block 3321; when the receiving unit 331 and the positioning unit 332 are closed, the positioning block 33211 extends into the material receiving groove 3312, so that the positioning block 33211 and the material receiving groove 3312 form a material receiving position.

[0094] The receiving unit 331 has a feeding mounting groove 3317 located directly below it. When the receiving unit 331 and the positioning unit 332 are closed, the feeding mounting groove 3317 and the positioning unit 332 form the mounting opening of the feeding part 36, that is, part of the structure of the feeding part 36 extends into the feeding mounting groove 3317. When the receiving unit 331 and the positioning unit 332 are unfolded, the receiving unit 331 and the positioning unit 332 move relative to the feeding part 36, causing the receiving unit 331 and the positioning unit 332 to move away from the feeding part 36. At the same time, the connector and the feeding part 36 remain relatively stationary. After the receiving unit 331 is disconnected from the connector, the connector falls onto the feeding part 36 due to its own weight.

[0095] The unloading section 36 includes a first unloading channel 361 and a second unloading channel 362. One end of the first unloading channel 361 extends into the mounting port, and the other end of the first unloading channel 361 is connected to the second unloading channel 362. A guide plate 363 is provided between the first unloading channel 361 and the second unloading channel 362, so that the connector can be smoothly guided from the first unloading channel 361 to the second unloading channel 362.

[0096] The unloading section 36 is provided with a gradually downward sloping ramp. The connector slides out of the pin assembly device from the unloading section 36 along the ramp. The ramp guides the connector to the external transmission structure and then smoothly transmits the connector to the subsequent processing station.

[0097] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details.
