A batch feeding equipment for parts

Abstract

This utility model discloses a batch feeding device for parts, belonging to the technical field of feeding equipment. The device uses a hydraulically driven tilting assembly to move a pushing block to deliver terminal carrier tape, replacing the traditional roller feeding method. When the pushing block tilts with the support block, it forms a unidirectional progressive contact with the terminal carrier tape, eliminating the reverse friction force generated by the reciprocating movement of the rollers. Furthermore, the feeding power is transmitted by the hydraulic cylinder through the push rod and support bar, avoiding transmission gaps between the rollers and the carrier tape. Simultaneously, the extension and retraction of the hydraulic cylinder is smooth, without the inertial force affecting motor start-up and shutdown, fundamentally eliminating the pull-back phenomenon of the terminal carrier tape. In addition, the V-shaped pushing block, in conjunction with the spring inside the support block, can elastically buffer and prevent damage to the terminals caused by hard contact, ensuring uniform force on the terminal carrier tape during delivery. This effectively prevents thinner terminals from deforming or breaking due to tensile force, improving overall processing quality and product quality.

Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically to a batch feeding equipment for parts. Background Technology

[0002] As a key component for achieving electrical connections, terminal blocks have extremely high requirements for efficiency and precision in their mass production process. During production, terminals arranged in rolls or strips need to be separated one by one according to the specified length by a cutting device to facilitate subsequent crimping, assembly and other processes. In this process, the batch feeding equipment for parts plays a crucial role. Among them, the roller feeding structure on the cutting device is widely used in the continuous feeding process of terminal blocks due to its simple structure and strong applicability.

[0003] However, existing feeding equipment using roller-type feeding structures has significant defects in actual operation: During continuous feeding, when the roller reciprocates and returns to its original position after completing the feeding action, the transmission gap between the roller and the terminal carrier tape, and the lack of effective control over the driving force during the roller's retraction, easily leads to reverse friction between the roller and the terminal carrier tape. This reverse friction causes the terminal carrier tape to be pulled back. On the other hand, if the acceleration and deceleration control of the drive motor is improper at the moment the roller starts and stops, the resulting inertial force will also exacerbate the pull-back phenomenon of the terminal carrier tape. Since the terminals are usually made of thin materials and have delicate structures, they are very easy to deform or even break under tensile force. This not only leads to damage to individual terminals, affecting the appearance and dimensional accuracy of the product, but also damages the electrical performance of the terminals, such as reducing contact reliability, thereby affecting the overall processing quality and significantly reducing product quality.

[0004] Based on this, the present invention designs a batch feeding device for parts to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a batch feeding device for parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A batch feeding device for parts includes a worktable, a feeding plate, a baffle, a cutting blade holder, and a cutting opening. The feeding plate is fixedly connected to the top surface of the worktable, the baffles are symmetrically fixedly connected to the top surface of the feeding plate, the cutting blade holder is fixed to the top surface of the worktable at one end of the feeding plate, and the cutting opening is opened on the surface of the cutting blade holder. It also includes a hydraulic cylinder, a pushing assembly, and a flipping assembly. The feeding plate is located above the hydraulic cylinder, and a fixing block is fixedly connected to the top surface of one of the baffles.

[0008] The pushing assembly includes a pushing block, which is symmetrically distributed on the top surface of the feeding plate and located between two baffles. A support block is sleeved on one end of the pushing block, and a flipping assembly is connected between the support block, the fixing block and the hydraulic cylinder.

[0009] Furthermore, an adjustment groove is provided at one end of the support block, and a spring is fixedly connected to one end of the inner wall of the adjustment groove. A protrusion is fixedly connected to the end of the push block near the support block, and the end of the protrusion away from the push block is fixedly connected to the end of the spring.

[0010] Furthermore, the push block is V-shaped.

[0011] Furthermore, an installation block is fixedly connected to the end of the support block away from the adjustment groove.

[0012] Furthermore, the flipping assembly includes a timing pulley, and the surface of the fixed block is rotatably connected to two shafts via bearings. One end of the shaft is fixedly connected to the surface of the mounting block, and the other end of the shaft passes through the fixed block and is fixedly connected to the timing pulley. The outer surfaces of the two timing pulleys are connected to a timing belt for transmission.

[0013] Furthermore, a support bar is fixedly connected to the outer surface of one of the rotating shafts, and the side wall of the support bar is opposite to the synchronous wheel. A pin is rotatably connected to the other end of the support bar. A push rod is rotatably connected to the end of the pin away from the support bar.

[0015] Furthermore, a pad is fixedly connected to the end of the feeding plate away from the cutting blade holder.

[0016] Compared with the prior art, the advantages of this utility model are as follows: This device uses a tilting component driven by a hydraulic cylinder to drive the pushing block to deliver the terminal carrier tape, replacing the traditional roller feeding method. When the pushing block tilts with the support block, it forms a one-way progressive contact with the terminal carrier tape, eliminating the reverse friction force generated by the reciprocating movement of the roller. Moreover, the feeding power is transmitted by the hydraulic cylinder through the push rod and support bar, avoiding the transmission gap between the roller and the carrier tape. At the same time, the extension and retraction of the hydraulic cylinder is smooth, without the influence of inertial force when the motor starts and stops, thus eliminating the pullback phenomenon of the terminal carrier tape from the root. In addition, the V-shaped pushing block, together with the spring in the support block, can avoid terminal damage caused by hard contact through elastic buffering, ensuring that the terminal carrier tape is subjected to uniform force during delivery, effectively preventing the thin terminal from deforming or breaking due to tensile force, thus improving the overall processing quality and product quality.

Detailed Implementation

[0026] 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. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] In some embodiments, please refer to the accompanying drawings. Figures 1-6A batch feeding device for parts includes a workbench 1, a feeding plate 2, a baffle 3, a cutting blade holder 4, and a cutting opening 5. The feeding plate 2 is fixedly connected to the top surface of the workbench 1, the baffle 3 is symmetrically fixedly connected to the top surface of the feeding plate 2, the cutting blade holder 4 is fixed to the top surface of the workbench 1 at one end of the feeding plate 2, and the cutting opening 5 is opened on the surface of the cutting blade holder 4. The device also includes a hydraulic cylinder 7, a pushing assembly, and a flipping assembly. The feeding plate 2 is located above the hydraulic cylinder 7, and a fixing block 8 is fixedly connected to the top surface of one of the baffles 3. The pushing assembly includes V-shaped pushing blocks 14, which are symmetrically distributed on the top surface of the feeding plate 2 and located between the two baffles 3. A support block 9 is sleeved on one end of the pushing block 14. A flipping assembly is connected between the support block 9, the fixing block 8, and the hydraulic cylinder 7. A pad 6 is fixedly connected to the end of the feeding plate 2 away from the cutting blade holder 4. The end of the pad 6 away from the feeding plate 2 has an arc-shaped surface, which can prevent the delivered terminal carrier tape from being worn.

[0028] In some embodiments, such as Figures 1-6 As shown in a preferred embodiment of the present invention, one end of the support block 9 is provided with an adjustment groove 10, and one end of the inner wall of the adjustment groove 10 is fixedly connected to a spring 12. The end of the push block 14 near the support block 9 is fixedly connected to a protrusion 13, and the end of the protrusion 13 away from the push block 14 is fixedly connected to the end of the spring 12. Normally, the end of the push block 14 away from the spring 12 is placed upward. When the opening of the support block 9 is downward, the surface of the push block 14 contacts the terminal carrier tape and delivers the terminal carrier tape to the cutting opening 5. During the process, the spring 12 is squeezed to avoid the push block 14 from hard contacting the terminal carrier tape and causing wear. Moreover, the push block 14 has a V-shaped structure, which can provide progressive stability when flipping and pushing the terminal carrier tape.

[0029] In some embodiments, such as Figures 1-6As shown in a preferred embodiment of this utility model, the end of the support block 9 away from the adjustment groove 10 is fixedly connected to the mounting block 15. The flipping assembly includes a synchronous wheel 17. The surface of the fixed block 8 is rotatably connected to two rotating shafts 16 via bearings. One end of the rotating shaft 16 is fixedly connected to the surface of the mounting block 15, and the other end of the rotating shaft 16 passes through the fixed block 8 and is fixedly connected to the synchronous wheel 17. The outer surfaces of the two synchronous wheels 17 are connected to a synchronous belt 18. The outer surface of one of the rotating shafts 16 is fixedly connected to a support bar 19, and the sidewall of the support bar 19 is opposite to but not in contact with the synchronous wheel 17. The other end of the support bar 19 is rotatably connected to a pin 21. The end of the pin 21 away from the support bar 19 is rotatably connected to a push rod 20. The end of the push rod 20 away from the pin 21 is rotatably connected to a rotating bolt 22. One end of the push rod 20 is fixedly connected to the telescopic end of the hydraulic cylinder 7. The support bar 19 and the push rod 20 are normally V-shaped. The end of the push rod 20 away from the shaft pin 21 is located at a high position. The hydraulic cylinder 7 is not fully extended in normal conditions. A support frame 23 is fixedly connected between the outer surface of the hydraulic cylinder 7 and the worktable 1. When the hydraulic cylinder 7 extends, the push rod 20 is pushed by the hydraulic cylinder 7. Then, the end of the push rod 20 near the support bar 19 pushes the support bar 19 downward. At this time, the end of the support bar 19 away from the shaft pin 21 rotates around the rotating shaft 16. Since the support bar 19 and the rotating shaft 16 are fixedly connected, the rotating shaft 16 can be rotated. Subsequently, the two rotating shafts 16 rotate synchronously through the transmission connection of the synchronous pulley 17 and the synchronous belt 18, so that the support block 9 at the other end of the rotating shaft 16 can continuously rotate to deliver the terminal carrier tape.

[0030] Before using the device, firstly, place the terminal carrier tape on the top surface of the feeding plate 2 and between two symmetrically distributed baffles 3. After the starting end of the terminal carrier tape is transitioned by the pad plate 6, it extends towards the cutting blade holder 4, so that the part of the terminal carrier tape to be cut is aligned with the cutting opening 5 on the surface of the cutting blade holder 4. At this time, the push block 14 is in normal state, with the end away from the spring 12 placed upward. The opening direction of the support block 9 is adapted to the state of the push block 14. The support bar 19 and push rod 20 in the flipping assembly are V-shaped. The end of the push rod 20 away from the shaft pin 21 is located at a high position, and the hydraulic cylinder 7 is in the initial state of not fully extended.

[0031] When the cutting operation begins, the hydraulic cylinder 7 extends, and its telescopic end pushes the push rod 20 through the rotating bolt 22. The end of the push rod 20 away from the rotating bolt 22 pushes the support bar 19 downward with the shaft pin 21 as the fulcrum. This causes the support bar 19 to drive the rotating shaft 16, which is fixedly connected to it, to rotate around the bearing on the fixed block 8. Since the two rotating shafts 16 are connected by the synchronous pulley 17 and the synchronous belt 18, they will rotate synchronously, thereby causing the support block 9 at the other end of the rotating shaft 16 to flip. When the opening of the support block 9 faces downward, the push block 14 flips with the support block 9 to the surface to contact the terminal carrier tape, forming a V-shape. During the flipping process, the push block 14 of the structure delivers the terminal carrier tape to the cutting opening 5 in a progressive and stable manner. During the delivery process, the terminal carrier tape exerts a reverse force on the push block 14, causing the protrusion 13 at one end of the push block 14 to move into the adjustment groove 10 of the support block 9, compressing the spring 12. The elastic deformation of the spring 12 avoids hard contact between the push block 14 and the terminal carrier tape, preventing wear of the carrier tape. As the hydraulic cylinder 7 continues to push, the push block 14 accurately delivers the terminal carrier tape to the cutting opening 5. At this time, the cutting mechanism in the cutting blade holder 4 cuts the terminal carrier tape through the cutting opening 5.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
