[0030] The current technology of the insertion machine feeding station is not stable enough in the process of conveying electronic components on the material belt one by one. It has low feeding accuracy, poor stability and is prone to failure and error.

[0031] The following is a preferred embodiment of a precise material feeding station device provided by this utility model that can solve the above-mentioned technical problems.

[0032] Please refer to Figures 1, 2, and 3. In the figures, units with similar structures are represented by the same labels.

[0033] This embodiment provides a station device for precise control of material feeding, used to feed electronic components 21 connected by a material strip 22 one by one. The structure of the electronic components 21 and the material strip 22 can be seen in Figure 4.

[0034] The precise control station device for material feeding in this embodiment includes: station body plate 11, feeding track block 12, main drive rod 13, gear cutter 17, block cutter 18, and feeding spring 19.

[0035] Two feeding track blocks 12 are set on one side of the station body plate 11. The two feeding track blocks 12 are provided with guide grooves 121 on the side that are close to each other. Electronic components 21 are guided and transported between the two guide grooves 121. The guide grooves 121 penetrate the top surface of the feeding track blocks 12 to form an inlet, and the guide grooves 121 penetrate the bottom surface of the feeding track blocks 12 to form an outlet.

[0036] The main drive rod 13 is rotatably connected to the station body plate 11, and the main drive rod 13 is located below the outlet. It should be noted that end plates 111 for rotatably setting the main drive rod 13 can be provided at both ends of one side of the station body plate 11.

[0037] The gear cutter 17 is fixedly connected to the main drive rod 13, and the block cutter 18 is fixedly connected to the station body plate 11. Each guide groove 121 is provided with a gear cutter 17 and a block cutter 18 on its extension trajectory. The gear cutter 17 and the block cutter 18 intersect in the axial direction of the main drive rod 13. When the pins of the electronic component 21 are conveyed to the intersection of the gear cutter 17 and the block cutter 18, the gear cutter 17 rotates and cooperates with the block cutter 18 to cut the pins of the electronic component 21, so that the electronic component 21 is separated from the material belt 22. Then the electronic component 21 can fall onto the corresponding chain clamp for conveying and feeding.

[0038] The feeding spring 19 is located between two feeding track blocks 12. One end of the feeding spring 19 is fixedly connected to the station body, and the other end of the feeding spring 19 extends between two guide slots 121. The feeding spring 19 can form a certain obstruction for the electronic components 21, preventing the electronic components that have passed through the feeding spring 19 from flowing back, and at the same time preventing the electronic components that have not passed through the feeding spring 19 from being over-fed (over-fed components are likely to be fed simultaneously in the next feeding stroke), thus enabling precise and stable control of the feeding of electronic components.

[0039] Referring to Figures 2 and 3, in this embodiment, the feeding spring 19 has a U-shaped structure. The middle part of the feeding spring 19 is fixedly connected to the station body, and both ends of the feeding spring 19 extend between the two guide grooves 121. This can form a certain obstruction on the pins of the electronic component 21, preventing abnormal feeding of the electronic component 21.

[0040] In this embodiment, the precise control of the feeding station also includes a rubber wheel 141, which is sleeved on the outer periphery of the main drive rod 13. The two ends of the feeding spring 19 are baffle ends 191, which contact the rubber wheel 141 to form a curved structure. The curved and protruding side of the baffle end 191 faces the inlet, which facilitates the output of the pins of the electronic component 21 by overcoming the resistance of the feeding spring 19 along the circumference of the rubber wheel 141, while preventing the pins from flowing back towards the inlet.

[0041] Specifically, the guide groove 121 includes an arc-shaped groove segment, which allows the electronic component 21 to be conveyed along the circumferential trajectory of the gear cutter 17. The center of the arc-shaped groove segment is located on the central axis of the main drive rod 13, and the circumferential surface of the rubber wheel 141 is located within the axial extension region of the arc-shaped groove segment.

[0042] A rubber wheel 141 is provided at each position corresponding to the stop end 191, and the stop end 191 is in elastic contact with the circumferential surface of the rubber wheel 141. When the gear cutter 17 and the block cutter 18 cut the leads of the electronic component 21, the leads of the electronic component 21 are simultaneously located between the stop end 191 and the rubber wheel 141, which can improve the stability of the gear cutter 17 and the block cutter 18 in cutting the leads of the electronic component.

[0043] In this embodiment, the precise control of the feeding station device also includes a fixing spring 142. The fixing spring 142 is sleeved on the outer periphery of the main drive rod 13. The fixing spring 142 is compressed between the two rubber wheels 141, and the position of the two rubber wheels 141 is restricted by the fixing spring 142.

[0044] Furthermore, the gear cutter 17 includes circumferentially located teeth, with the inner end of the teeth located within the axial extension region of the arc-shaped groove segment, and the outer end of the teeth (the end of the teeth furthest from the gear cutter 17 is the outer end) located outside the axial extension region of the arc-shaped groove segment. This ensures that the leads of the electronic component 21 are stably confined between the tooth grooves and the inner wall of the arc-shaped groove segment, allowing for stable transport of the electronic component 21. Simultaneously, the leads of the electronic component 21 are stably sheared by the gear cutter 17 and the block cutter 18.

[0045] In this embodiment, a notch 122 is provided at the bottom of the feeding track block 12. The guide groove 121 is connected to the notch 122. The gear cutter 17 and the block cutter 18 are located in the notch 122, so that the gear cutter 17 and the block cutter 18 can be set on the extension trajectory of the guide groove 121, so that the electronic component 21 can be cut by the gear cutter 17 and the block cutter 18 during the process of conveying along the guide groove 121.

[0046] Referring to Figure 2, the precise control feeding station device in this embodiment also includes a baffle plate 1A. One end of the baffle plate 1A extends into the notch 122, and the gear cutter 17 and the block cutter 18 are located on the side of the baffle plate 1A near the notch 122. Due to the notch 122, the arc-shaped groove segment of the guide groove 121 is continuous along the axial direction. The baffle plate 1A can restrict the electronic component 21 and the material strip 22, so that the gear cutter 17 and the block cutter 18 can perform more stable and precise cutting on the pins of the electronic component 21.

[0047] In this embodiment, the baffle plate 1A includes a first plate 1A1 and a second plate 1A2. The first plate 1A1 and the second plate 1A2 are connected in an L-shaped structure. The extension plane of the first plate 1A1 and the extension plane of the second plate 1A2 are perpendicular. The first plate 1A1 is connected to the side of the unloading track block 12 away from the station body plate 11. The second plate 1A2 extends into the notch 122.

[0048] Alternatively, an elongated hole extending axially along the main drive rod 13 can be provided on the first plate 1A1, and a screw can pass through the elongated hole to connect with a threaded hole on the feed track block 12. The elongated hole allows the second plate 1A2 to adjust the limiting position of the electronic component 21 and the feed strip 22, so as to adjust the second plate 1A2 to the optimal limiting guide position.

[0049] In addition, the precise control of the feeding station device in this embodiment also includes a paper baffle block 16. The paper baffle block 16 is connected to the side of the feeding track block 12 away from the station body plate 11. The paper baffle block 16 extends on the side of the notch 122 away from the station body plate 11. The paper baffle block 16 can make the separated material strip 22 better guided to both sides of the station device.

[0050] Referring to Figures 1 and 2, in this embodiment, the precise control station device for feeding also includes a brake gear 151, a brake pulley 154, a brake body 152, and a brake spring 153.

[0051] Brake gear 151 is fixedly connected to main drive rod 13, and brake body 152 is rotatably connected to station body plate 11. The rotation axis of brake body 152 is parallel to the axial direction of main drive rod 13. Brake pulley 154 is rotatably mounted on brake body 152, and brake gear 151 is located on the trajectory of brake pulley 154 as brake body 152 rotates. Brake spring 153 is compressed and disposed between brake body 152 and station body plate 11. A mounting block 112 may be provided on station body plate 11 to mount brake spring 153 between brake body 152 and mounting block 112.

[0052] The spring force of the brake spring 153 drives the brake body 152 to rotate closer to the brake gear 151, so that the brake pulley 154 engages with the brake gear 151. This ensures that the main drive rod 13 rotates precisely one stroke each time, while the electronic components move and convey one unit stroke accordingly, achieving precise and stable control of the electronic component feeding.

[0053] Additionally, a manually operated rotary handle can be provided at one end of the main drive rod 13 to facilitate manual control of the rotation of the main drive rod 13, thereby facilitating the installation of electronic components 21 and material strip 22 into the guide groove 121, and also aiding in the debugging of the stationing device. One end of the main drive rod 13 is connected in transmission with a corresponding rotary drive mechanism.

[0054] The working principle of this utility model is as follows: First, the material strip 22 connected with electronic components 21 enters from the inlet of the guide groove 121 and reaches the intersection of the gear cutter 17 and the block cutter 18. The main drive rod 13 can be rotated by manually operating the rotating handle, so that a certain number of electronic components 21 are successively cut by the gear cutter 17 and the block cutter 18 to achieve the purpose of debugging. After the cut-off lead of the electronic components is qualified, the main drive rod 13 can be controlled by the corresponding rotation drive mechanism to rotate for automatic cyclic operation.

[0055] During the lead-cutting and conveying process of electronic component 21, the leads of electronic component 21 reach the tooth groove of gear cutter 17. The teeth of gear cutter 17 squeeze the leads of electronic component 21 and drive electronic component 21 to move along guide groove 121 at a certain stroke cycle. When electronic component 21 approaches the intersection of gear cutter 17 and block cutter 18, the leads of electronic component 21 are conveyed along the circumference of rubber wheel 141, overcoming the resistance of feed spring 19. Feed spring 19 makes it easier for electronic component 21 to be conveyed in the direction of guide outlet, and less likely to flow back in the direction of guide inlet.

[0056] Then, the gear cutter 17 and the block cutter 18 complete the cutting operation on the pins of the electronic component 21. The cut electronic component 21 falls into the corresponding chain clamp for conveying and feeding, and the cut material strip 22 is blocked and guided by the paper guide block 16 to be discharged to both sides of the station device.

[0057] This completes the process of the shearing foot conveying of the station device for precise control of material feeding in this preferred embodiment.

[0058] The station device in this preferred embodiment improves the stability of cutting the leads of electronic components by setting a feeding spring, and also prevents the return of electronic components that have passed through the feeding spring, while preventing the over-feeding of electronic components that have not passed through the feeding spring, thus enabling precise and stable control of electronic component feeding.

[0059] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
