Description

Technical Field

[0001] This invention relates to the field of assembly, and more specifically to a carrier structure for a pin insertion 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 generally made of plastic, while the pins are made of conductive metals or alloys such as copper, silver, or gold. Currently, the methods for installing pins onto connectors include at least injection molding to cover the pins or pressing the pins into the mounting holes on the connector. In the method of pressing the pins into the mounting holes on the connector, the pins need to be precisely inserted into the mounting holes of the connector, requiring the connector to be placed in a fixed position so that the mounting holes correspond to the pins. Therefore, during assembly, the connector placed on the carrier needs to be adjusted to a fixed position. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] In the accompanying drawings, shapes and dimensions may be enlarged for clarity, and the same reference numerals will be used in all figures to indicate the same or similar parts.

[0048] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains. The terms “first,” “second,” and similar terms used in this patent application specification do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an,” “a,” or “the,” and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms “comprising,” “including,” and similar terms mean that the elements or objects preceding “comprising” or “including” encompass the elements or objects listed following “comprising” or “including” and their equivalents, but do not exclude other elements or objects. The terms “upper,” “lower,” “left,” and “right,” etc., are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0049] In the following description, terms such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, and lower are defined relative to the structure shown in the accompanying drawings. In particular, "height" corresponds to the dimension from top to bottom, "width" corresponds to the dimension from left to right, and "depth" corresponds to the dimension from front to back. These are relative concepts and may vary depending on their location and usage. Therefore, these or other orientations should not be interpreted as restrictive terms.

[0050] 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.

[0051] According to one embodiment of the present invention, Figure 1-8 As can be seen from the diagram, a carrier structure for a pin insertion device includes a carrier 33 and a drive unit 32. In this embodiment, the carrier 33 includes a receiving unit 331 and a positioning unit 332. 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 joined together to form a material receiving position. The drive unit 32 is used to drive the receiving unit 331 and / or the positioning unit 332.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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 pins are pulled out 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 connector is unloaded from the pin groove 33121 by the pins, so that the connector is separated from the carrier structure and the receiving relationship is facilitated.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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. 1. During the closing process of the positioning unit 332, the connector is pushed by the guide bevel to move 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 carrier structure.

[0064] 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.

[0065] 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.

[0066] In a preferred embodiment, the carrier structure further includes a base plate 31, with a gear 312 connected to the base plate 31. The base plate 31 is also equipped with a guide portion 34, which 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 has 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 installed on the base plate 31. The guide rod 311 is slidably connected to the push plate 3323, and the sliding direction of the push plate 3323 is limited by the guide rod 311, thereby limiting the sliding direction of the entire positioning unit 332.

[0067] 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.
