Description

Technical Field

[0001] This utility model relates to the technical field of feeding mechanisms, specifically to a terminal feeding mechanism. Background Technology

[0002] Currently, the terminal feeding mechanism mainly uses rollers and needle rollers for conveying, as shown in the instruction manual. Figure 3 As shown, the terminal has a slot 27. When the roller rotates, the needle on the roller will enter the slot and push the terminal forward as the roller rotates. However, in this structure, the terminal at the tail end of the terminal block cannot be conveyed because it cannot contact the needle, resulting in waste of the terminal block tail material. In view of this, this application proposes a terminal feeding mechanism to reduce the waste of tail terminal material. Utility Model Content

[0003] The purpose of this utility model is to provide a terminal feeding mechanism in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figures 1-4As shown, an embodiment of this utility model discloses a terminal feeding mechanism, including a track 1 for accommodating terminals, terminal blocks laid flat within the track 1, and terminals having circular holes 26. A mounting block 4 is slidably mounted on the track 1 along the terminal travel direction. The mounting block 4 reciprocates within a certain distance. A linkage block 5 is hinged to the mounting block 4. A rod 9 is vertically slidably mounted on the mounting block 4. A bracket 13 is mounted on the mounting block 4, and the rod 9 slides with the bracket 13. The rod 9 is inserted into the circular hole 26. A first through hole 10 is constructed on the linkage block 5. A first column 11 is mounted on the rod 9, passing through and tangential to the first through hole 10. A driving mechanism for driving the linkage block 5 to rotate around the hinge point is mounted on the mounting block 4. Based on the above disclosure, this utility model uses the movement of the rod 9 to push the terminal, driving the terminal movement. The overall design of the moving device in this application should be compact. Furthermore, it is installed near the terminal unloading position. Unlike roller rotation, which requires a large working space and the distance between the two needle rollers should be consistent with the distance between the two adjacent terminals through the slot 27, it is subject to many limitations. In this application, the position of the insertion rod 9 is changed by the movement of the mounting block 4. When the linkage block 5 rotates, the first column rod 11 is forced to move through the first through hole 10, which drives the insertion rod 9 to be inserted into the round hole 26. Thus, when the insertion rod 9 moves, it can move the terminal. The movement distance of the insertion rod 9 is limited by the mounting block 4, and the movement distance of the mounting block 4 is the distance between the two round holes 26. Thus, through the continuous reciprocating movement of the mounting block 4 and the continuous reciprocating movement of the insertion rod 9, the indirect delivery of the terminal is achieved. Compared with the existing roller needle roller delivery, this feeding mechanism can be installed near the unloading position and the movement trajectory is short. Therefore, the amount of tail material that cannot be delivered will be less than that of the existing roller needle roller structure, reducing tail material waste.

[0022] like Figures 1-4 As shown, to ensure the stability of terminal conveying, a conveying groove is constructed on the track 1, and the terminal is located in the conveying groove. The thickness of the terminal is equal to the depth of the conveying groove. A pressure plate 2 covering the conveying groove is installed on the track 1. The pressure plate 2 is constructed with an operating hole 25. After the pressure plate 2 covers the conveying groove, it forms a limit on the terminal, so that the terminal will only move in a straight line during the conveying process in the track 1.

[0023] like Figure 1 As shown, in some embodiments, an observation channel 3 for observation terminals is reserved between the pressure plate 2 and the track 1, through which the movement of the terminals in the track 1 can be observed.

[0024] like Figures 1-4As shown, to achieve the rotation of the linkage block 5, the driving mechanism includes a first cylinder 6 mounted on the mounting block 4. The piston rod of the first cylinder 6 is connected to a driving block 7. A push rod 8 is mounted on the driving block 7. The linkage block 5 has a second through hole 12. The push rod 8 passes through the push rod 8 and is tangential to it. The first cylinder 6 drives the driving block 7 and the push rod 8 to move linearly. During the movement of the push rod 8 in the second through hole 12, it drives the linkage block 5 to rotate around the hinge point, thereby realizing the movement of the insertion rod 9. With the extension and retraction of the piston rod, the insertion rod 9 is lowered and raised. During the movement of the mounting block 4, the insertion rod 9 remains stationary.

[0025] like Figures 1-4 As shown, in order to realize the movement of the mounting block 4, a linear guide rail 14 is installed on the track 1, and a linear slider 15 is slidably installed on the linear guide rail 14. The mounting block 4 is installed on the linear slider 15. It also includes a second cylinder 16 connected to the piston rod of the mounting block 4. The mounting block 4 can be pushed to slide back and forth directly by the second cylinder 16. The linear guide rail 14 and the linear slider 15 cooperate to play a guiding role.

[0026] like Figures 1-4 As shown, to improve the stability of the terminal block and prevent misalignment when the insertion rod 9 separates from the terminal, in some embodiments, a linkage rod 17 is hinged to the pressure plate 2, the linkage rod 17 has a third through hole 18, a locking rod 20 is slidably mounted on the pressure plate 2, a sliding sleeve 19 is mounted on the pressure plate 2, the locking rod 20 and the sliding sleeve 19 are slidably engaged, a second column rod 21 is mounted on the locking rod 20, the second column rod 21 passes through and is tangent to the third through hole 18, a connecting rod 22 is hinged to the end of the linkage rod 17, a sliding seat 23 is hinged to the end of the connecting rod 22, and a third cylinder 24 is mounted on the pressure plate 2, the piston rod of the third cylinder 24 is connected to the sliding seat 23. When the insertion rod 9 is inserted into the round hole 26 and drives the terminal to move, the locking rod 20 is not inserted into the round hole 26. This technical solution is illustrated by an embodiment. According to the instruction manual, assuming there are first and second circular holes spaced apart, with a first position, a second position, and a third position set. Initially, the first and second circular holes are located at the first and second positions, respectively. When the insertion rod 9 is inserted into the first circular hole and moves the first circular hole from the first position to the second position, the second circular hole moves from the second position to the third position. When the first circular hole reaches the second position, the third cylinder 24 works, pushing the slide 23 to move. Driven by the connecting rod 22, the linkage rod 17 rotates and presses the locking rod 20 to move into the second circular hole, completing the locking of the terminal. At this time, the insertion rod 9 separates from the first circular hole and is reset under the action of the mounting block 4, thus being inserted into the next circular hole for terminal delivery. During this process, the locking rod 20 separates from the second circular hole and does not interfere with the delivery of the terminal.
