In the transmission and installation process of the pins, specific tools or devices need to be used to carry and guide the pins. However, the conventional pin conveying device mostly relies on the conveying groove of fixed size to convey the pins. Due to the size variation in the manufacturing process of the pins, in order to ensure that all the pins within the allowable tolerance range can be smoothly put into the conveying groove, the design size of the groove is usually slightly larger than the maximum tolerance size of the pins. Although this design can accommodate the size difference, it also causes the pins to be loose during conveying; in the extreme case, the pins may fall off from the conveying groove, thereby interfering with the normal assembly process.

[0040] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0041] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0042] like Figures 1 to 7 As shown, a conveying device for inserting needles according to the present invention includes: a conveying track 1, a slide 2, and an adsorption element 3.
[0043] Specifically, the conveying track 1 preferably uses a linear vibrator. A linear vibrator is a mechanical device that can generate periodic vibration in a linear direction. It is suitable for conveying pins 21, which are arranged on the conveying track 1. A slide table 2 is movably arranged on the side of the conveying track 1. The slide table 2 has a receiving position and a feeding position. When it is in the receiving position, the slide table 2 is located at the discharge end of the conveying track 1 and is used to receive a single pin 21. When it is in the feeding position, the slide table 2 drives the pins 21 on it to separate from the pins 21 on the conveying track 1. The suction member 3 has a fixing part arranged on the slide table 2. The fixing part is used to fix the pins 21 on the slide table 2 to the slide table 2.
[0044] During operation, the pins 21 are closely arranged on the conveyor track 1. The slide 2 is located at the discharge end of the conveyor track 1. When the slide 2 receives the pin 21, the suction member 3 provides power to the fixing part, so that the pin 21 is firmly fixed on the slide 2. Then, the slide 2 moves from the receiving position to the feeding position, separating the single pin 21 from the other closely arranged pins 21 on the conveyor track 1. During the process of the slide 2 conveying the pin 21, the fixing part always keeps the pin 21 fixed on the slide 2, ensuring the stability of the pin 21, thereby ensuring that the pin 21 can be assembled normally.
[0045] In order to realize the positioning of the pin 21 on the sliding table 2, in the present scheme, a positioning groove 4 is arranged on the sliding table 2, which is matched with the shape of the pin 21. The depth of the positioning groove 4 on the side of the sliding table 2 facing the conveying track 1 is not greater than the thickness of the pin 21, so as to accommodate one pin 21 when the conveying track 1 conveys the pin 21, and to prevent the pin 21 adjacent to the positioning groove 4 from being separated from the conveying track 1, thereby ensuring the stability of the subsequent pin 21 on the conveying track 1.
[0046] In one embodiment, the suction accessory 3 can be an electromagnet, and the suction end thereof serves as the fixing part. When the electromagnet is powered on, it generates a suction force on the pin 21, so that the pin 21 can be firmly adsorbed on the sliding table 2.
[0047] In another embodiment, the suction accessory 3 comprises a gas channel 5, a gas joint 6 and a vacuum generator 7. The present scheme further comprises a workbench 20 for supporting the conveying track 1 and the suction accessory 3. The vacuum generator 7 is installed on the workbench 20, and the gas channel 5 is arranged on the sliding table 2 and communicates with the positioning groove 4 at one end, thereby constituting the fixing part. The gas joint 6 is connected to the other end of the gas channel 5 and is connected to the vacuum generator 7 through a pipeline.
[0048] In operation, when the pin 21 is conveyed to the positioning groove 4, the vacuum generator 7 is started to extract air in the gas channel 5, so as to form a negative pressure in the gas channel 5. At this time, the fixing part has the ability to fix the pin 21 on the sliding table 2, thereby ensuring the stability of the pin 21 during the movement of the sliding table 2.
[0049] In the present scheme, in order to enable the sliding table 2 to move relative to the conveying track 1, a driving member 8 is further included. The driving member 8 can be a combination of a motor and a lead screw, a linear guide rail or an air cylinder, etc. The driving member 8 is arranged on one side of the conveying track 1, and functions to drive the sliding table 2 to move to a feeding position after the pin 21 on the sliding table 2 is firmly fixed in the positioning groove 4 by the fixing part, and to drive the sliding table 2 to return to a receiving position after the pin 21 on the sliding table 2 is taken away by a subsequent assembly process, thereby preparing for the next conveying of the pin 21.
[0050] In order to realize the automatic linkage between the driving member 8 and the conveying track 1, a first sensor 9 is further included in the present scheme. The first sensor 9 is installed on the sliding table 2 and is electrically connected to the driving member 8. When the conveying track 1 conveys a single pin 21 to the positioning groove 4, the first sensor 9 senses the presence of the pin 21 in the positioning groove 4, and triggers the action of the driving member 8, thereby driving the sliding table 2 to move from the receiving position to the feeding position. The first sensor 9 functions to ensure the automatic operation of the entire conveying system, and to ensure the accuracy and efficiency of the conveying process of the pin 21.
[0051] Reference Figure 4The sliding table 2 in the scheme comprises a sliding seat 10, a material conveying block 11, a mounting seat 12, a first limiting block 13, and a second limiting block 14.
[0052] The sliding seat 10 is connected to the output end of the driving member 8, and is used to drive the whole sliding table 2 to move through the sliding seat 10 when the driving member 8 is in action; the material conveying block 11 is connected to the sliding seat 10, and the positioning groove 4 is arranged on the material conveying block 11, and is used to realize the accurate positioning of the pin 21 on the sliding table 2; the mounting seat 12 is connected to the material conveying block 11; the first limiting block 13 is connected to the upper end of the sliding seat 10 and the material conveying block 11; and the second limiting block 14 is connected to the material conveying block 11 and is arranged opposite to the first limiting block 13. A limiting space is formed between the first limiting block 13, the second limiting block 14, and the mounting seat 12, and is used to provide the limiting for the first sensor 9.
[0053] The connection between the material conveying block 11 and the sliding seat 10, the first limiting block 13 and the sliding seat 10 and the material conveying block 11, the first limiting block 13 and the material conveying block 11, the mounting seat 12 and the material conveying block 11, and the second limiting block 14 and the material conveying block 11 is preferably detachable connection achieved through bolt connection. Through this connection mode, when the size of the pin 21 is different due to the different models of the transformer to which the pin 21 needs to be installed, the material conveying block 11 can be quickly replaced according to the size of the pin 21. The mounting seat 12 is used to fix the position of the first sensor 9 on the sliding table 2, and the limiting space formed by the mounting seat 12, the first limiting block 13, and the second limiting block 14 ensures the stability of the first sensor 9 on the sliding table 2.
[0054] Referring to Figure 2 The scheme further comprises a blocking block 15, which is arranged on one side of the conveying track 1, and when the sliding table 2 moves to the feeding position, the blocking block 15 blocks at the opening of the positioning groove 4, and is used to fix the pin 21 between the sliding table 2 and the blocking block 15.
[0055] After the sliding table 2 conveys a single pin 21 to the feeding position, but before the pin 21 on the sliding table 2 is taken away in the subsequent process, the fixing part needs to release the fixation of the pin 21. At this time, the blocking block 15 will block at the opening of the positioning groove 4, so that the pin 21 can be kept on the sliding table 2, thereby maximizing the stability of the pin 21.
[0056] Referring to Figure 1The solution also includes: a vibratory feeder 16, the discharge end of which is connected to the feed end of the conveying track 1, for conveying the pins 21 to the conveying track 1; a support frame 17, which is disposed on one side of the discharge end of the conveying track 1, and the slide table 2 is movably disposed on the support frame 17; a guide plate 18, which is disposed on the support frame 17 and parallel to the conveying track 1, for providing guidance for the pins 21 on the conveying track 1; and a second sensor 19, which is disposed on one side of the conveying track 1 and electrically connected to the vibratory feeder 16, for controlling the vibratory feeder 16 to intermittently feed the conveying track 1.
[0057] The support frame 17 supports the slide table 2. During operation, the vibratory feeder 16 arranges the pins 21 in a predetermined direction and transports them to the conveyor track. In this design, since the feeding speed of the vibratory feeder 16 is higher than that of the slide table 2, to prevent excessive accumulation of pins 21 on the conveyor track, a second sensor 19 electrically connected to the vibratory feeder 16 is installed on one side of the conveyor track. When the pins 21 on the conveyor track accumulate to a level that the second sensor 19 can detect, the sensor triggers the control system, causing the vibratory feeder 16 to pause feeding.
[0058] It is worth noting that the second sensor 19 is designed to only start working after a certain number of pins 21 have been collected on the conveyor track. This avoids the second sensor 19 mistakenly triggering the control system when it detects a small number of pins 21 passing by as the vibratory feeder 16 begins to transport pins 21 onto the conveyor track, thus preventing the vibratory feeder 16 from unnecessarily stopping.
[0059] The structure of the vibratory feeder 16 in this solution is common knowledge to those skilled in the art, and therefore is not described in detail here.
[0060] Preferably, the positioning groove 4 is two semi-cylindrical grooves spaced apart on the slide table 2.
[0061] More preferably, the moving direction of the slide table 2 is perpendicular to the feeding direction of the conveying track 1.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. The terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two elements or the interaction between two elements, unless otherwise explicitly specified.
