Description

Technical Field

[0001] The utility model belongs to the field of strip tantalum capacitor lead cutting equipment, and particularly relates to an automatic lead cutting equipment for strip tantalum capacitors. Background Art

[0002] With the continuous development of electronic information equipment, the market demand for chip tantalum capacitors is increasing day by day. Improving production capacity while ensuring quality has become one of the most urgent matters in the current electronic component industry. In addition to improving production capacity by purchasing equipment, etc., it is also possible to increase the production capacity by increasing the number of products loaded on each lead frame.

[0003] However, once the product density of each lead frame is increased, it will cause the plastic overflow between products to be relatively short and firm, resulting in difficulty in completely removing the overflow during the sandblasting process. The remaining overflow will affect the pin forming of products in subsequent processes. Therefore, before pin forming, each lead frame needs to be subjected to lead cutting treatment; currently, the lead cutting on the market requires manual operation, which reduces the production and processing efficiency on the one hand and increases the labor cost on the other hand, and needs to be further improved.

Specific embodiments

[0032] The present utility model will be further described below through specific embodiments.

[0033] Referring to Figures 1 to 10 As shown, an automatic lead cutting device for strip tantalum capacitors includes a loading device 1, a feeding device 2, a traction device 3, a lead cutting device 4 and a material collecting device 5.

[0034] The strip tantalum capacitor 6 includes a frame 61, a plurality of tantalum capacitor units 62 arranged at intervals on the frame 61, and a plurality of positioning holes 63 arranged at intervals along the length direction of the frame 61.

[0035] The feeding device 1 is used to discharge strip tantalum capacitors and send the discharged strip tantalum capacitors into the feeding device 2 one by one. It includes a feeding table 11, a feeding component 12 rotatably arranged on the feeding table 11, and an air-sending nozzle 13 arranged on one side of the feeding table 11 opposite to the feeding device 2. Specifically, the feeding component 12 includes a feeding conveyor belt 14, a plurality of feeding plates 15 arranged at intervals around the feeding conveyor belt 14, and a driving component 16 arranged on the feeding table 11 to connect and drive the feeding conveyor belt 14 to rotate. A placing cavity 17 for placing strip tantalum capacitors is formed between two adjacent feeding plates 15. When the front feeding plate rotates downward to be flush with the feeding device 2, the strip tantalum capacitor 6 will be placed flat on the feeding plate 15 under the action of gravity. At this time, the air-sending nozzle 13 works to send the strip tantalum capacitor 6 placed flat on the feeding plate 15 into the feeding device 2.

[0036] The feeding device 2 is used to receive the strip tantalum capacitors conveyed by the feeding device 1. It includes a feeding table 21, a feeding track 22 movably arranged up and down on the feeding table 21 for receiving strip tantalum capacitors, a lifting mechanism 23 connecting and driving the feeding track 22 to move up and down, a pressing mechanism 24 movably arranged above the feeding track 22 to limit the position of the strip tantalum capacitors, a limiting block 25 located at the rear end of the feeding track 22, and a driving motor 26 arranged on the feeding table 21 to connect and drive the feeding track 22 to work. During operation, the lifting mechanism 23 can drive the feeding track 22 to move down to the lower predetermined position to be flush with the feeding plate 15 to receive the strip tantalum capacitors conveyed by the air-sending nozzle 13, and then reset and move up to the upper predetermined position to connect the strip tantalum capacitors with the traction device 3. The limiting block 25 is arranged at the rear end of the feeding track 22 to limit the position of the strip tantalum capacitors on the feeding track 22 to ensure that the strip tantalum capacitors moving up with the feeding track 22 are connected with the traction device 3. Specifically, the lifting mechanism 23 includes a lifting cylinder arranged on the feeding table 21 and connected to the feeding track 22.

[0037] The pressing mechanism 24 includes a pressing plate 241 movably arranged above the feeding track 22, a pressing rod 242 arranged at the lower end of the pressing plate 241 and capable of contacting the strip tantalum capacitors, and a pressing cylinder 243 connecting and driving the pressing plate 241 to move up and down. By arranging the pressing mechanism 24, the strip tantalum capacitors during the upward movement process are fixed, so that the strip tantalum capacitors can stably rise to the predetermined position to prevent the strip tantalum capacitors from slipping and affecting their connection with the traction device 3.

[0038] The traction device 3 moves the strip tantalum capacitors on the feeding track 22 to the lead cutting device 4 for lead cutting treatment. It includes a traction plate 31 that can move back and forth relative to the feeding device 2, a positioning block 32 provided at the front end of the traction plate 31, a positioning post 33 provided on the positioning block 32 that can be embedded in the positioning hole 63, a pusher plate 34 provided on the traction plate 31 behind the positioning block 32, and a traction mechanism 35 that connects and drives the traction plate 31 to move back and forth. When the strip tantalum capacitor 6 is connected to the traction device 3, the lifting mechanism 23 drives the feeding track 22 carrying the strip tantalum capacitor to move upward to a predetermined upper position so that the positioning post 33 on the traction plate 31 is embedded in the relative positioning hole 63, completing the connection between the strip tantalum capacitor 6 and the traction plate 31. Specifically, the pusher plate 34 includes a connecting portion 341 connected to the traction plate 31 and an inverted L-shaped pusher portion 342 connected to the connecting portion 341, and the positioning post 33 is located directly in front of the pusher portion 342. During operation, when the pusher portion 342 can pull a strip tantalum capacitor into the lead cutting device 4 under the traction of the traction plate 31, it will push the strip tantalum capacitor that has completed the lead cutting treatment outwards into the collecting device 5. Further, the traction mechanism 35 includes a traction cylinder 351 and a connecting plate 352 connected between the traction cylinder 351 and the traction plate 31.

[0039] The lead cutting device 4 performs lead cutting treatment on the incoming strip tantalum capacitors. It includes a lead cutting table 41, a lead cutting lower die 42 that can move up and down and is provided on the lead cutting table 41 for placing strip tantalum capacitors, a lead cutting mechanism 43 that can move up and down above the lead cutting lower die 42 to perform lead cutting treatment on the strip tantalum capacitors, and a plurality of compression springs 44 connected between the lead cutting lower die 42 and the lead cutting table 41. Among them, when the lead cutting mechanism 43 moves downward to perform lead cutting treatment on the strip tantalum capacitors, under the action of the plurality of compression springs 44, the strip tantalum capacitor will move downward with the lead cutting lower die 42 to disengage the positioning hole 63 from the positioning post 33. At this time, the traction plate 31 can move in the direction close to the feeding device 2 under the action of the traction mechanism 35 to connect with the next strip tantalum capacitor. When the strip tantalum capacitor has completed the lead cutting treatment, the lead cutting mechanism 43 moves upward to reset, and the lead cutting lower die 42 also moves upward to reset under the action of the plurality of compression springs 44. At this time, the traction plate 31 can pull the next strip tantalum capacitor into the lead cutting lower die 42, and at the same time cooperate with the pusher plate 34 to push the strip tantalum capacitor that has completed the lead cutting treatment outwards into the collecting device 5.

[0040] The lead cutting lower die 42 includes a placement groove 421 for placing strip tantalum capacitors and a moving groove 422 provided on one side of the placement groove 421 and extending downward for the pusher plate 34 to move. Through the setting of the moving groove 422, it is ensured that during the lead cutting process of the strip tantalum capacitor, the traction plate 41 can drive the positioning block 32 and the pusher plate 34 to move forward without affecting each other's work.

[0041] The lead cutting mechanism 43 includes a lead cutting upper die 431 disposed above the lead cutting lower die 42, a plurality of elastic positioning columns 432 connected between the lead cutting upper die 431 and the lead cutting table 41, a cutting knife assembly 433 disposed on the lead cutting upper die 431 opposite to the placement groove 421, a lead cutting cylinder 434 capable of pressing down the lead cutting upper die 431, and a mounting bracket 435 disposed on the lead cutting table 431 for mounting the lead cutting cylinder 434; specifically, the cutting knife assembly 433 includes a mounting seat 436 disposed on the lead cutting upper die 431, a plurality of cutting knives 437 spaced apart and disposed opposite to the plurality of tantalum capacitor units 62 one by one on the mounting seat 436, a guide plate 438 disposed below the mounting seat 436, and a plurality of connecting springs 439 connecting the guide plate 438 and the mounting seat 436. The lead cutting cylinder 434 can press down the mounting seat 436 to move the plurality of cutting knives 437 downward to perform lead cutting on the strip-shaped tantalum capacitors in the placement groove 421; further, the guide plate 438 includes a guide plate body 4381, a plurality of moving holes 4382 spaced apart on the guide plate body 4381 for the plurality of cutting knives 437 to move up and down respectively, and a positioning portion 4383 disposed at the lower end of the guide plate body 4381 and in abutting contact with the top of the chip tantalum capacitor. And the positioning portion 4383 is formed with a relief groove 4384 extending upward from the bottom surface and opposite to the plurality of tantalum capacitor units 62, so that the positioning portion 4383 is in abutting contact with the frame 61 portions on both sides of the tantalum capacitor unit 62.

[0042] The material receiving device 5 includes a material receiving box disposed obliquely downward behind the lead cutting device 4.

[0043] The working principle of the present application specifically includes the following steps:

[0044] Step 1, manually place the strip-shaped tantalum capacitors of the whole batch into the placement cavity 17 one by one. When controlling the feeding conveyor belt 14 to work, the feeding plate 15 moves forward to drive the strip-shaped tantalum capacitors forward. At the same time, the lifting mechanism 23 controls the feeding track 22 to move down to the lower predetermined position. When the front end feeding plate 15 rotates downward to be flush with the feeding track 22, the air supply nozzle 13 works to blow the chip tantalum capacitors lying flat on the front end feeding plate 15 due to gravity onto the feeding track 22;

[0045] Step 2, the feeding track 22 works to convey the received chip tantalum capacitors to the front end of the strip-shaped tantalum capacitors and abut against the limiting block 25. The lifting mechanism 23 simultaneously controls the feeding track 22 to move up to the upper predetermined position, so that the positioning columns 33 are inserted into the corresponding positioning holes 63 to complete the connection between the traction plate 31 and the strip-shaped tantalum capacitors;

[0046] Step 3: The traction cylinder 351 operates to drive the traction plate 31 to move away from the feeding track 22, enabling the chip tantalum capacitor to enter the placement groove 421 of the under die 42 for lead cutting. The lead cutting cylinder 434 operates to press down the mounting seat 436, causing multiple cutting blades 437 to move downward to perform lead cutting on the strip-shaped tantalum capacitors in the placement groove 421. At this time, the strip-shaped tantalum capacitors will move downward with the under die 42 for lead cutting, causing the positioning holes 63 to disengage from the positioning posts 33. The traction plate 31 can move in the direction close to the feeding track 22 under the action of the traction cylinder 351 to connect with the next strip-shaped tantalum capacitor.

[0047] Step 4: After the lead cutting operation is completed, the lead cutting cylinder 434 resets. The upper die 431 for lead cutting drives the multiple cutting blades 437 to move upward and reset under the action of multiple elastic positioning posts 432. The under die 42 for lead cutting also moves upward and resets under the action of multiple compression springs 44. Then, the traction cylinder 351 operates to pull the next strip-shaped tantalum capacitor into the under die 42 for lead cutting. During the process of the next strip-shaped tantalum capacitor entering, the traction plate 31 cooperates with the pusher plate 34 to push the strip-shaped tantalum capacitors that have completed the lead cutting process outwards into the receiving device 5, completing the lead cutting and collection work of the strip-shaped tantalum capacitors.

[0048] The automatic lead cutting equipment defined in this application is composed of a feeding device 1, a feeding device 2, a lead cutting device 4, a traction device 3, and a receiving device 5 that cooperate with each other to perform automatic feeding, positioning, waste removal, and receiving operations on strip-shaped tantalum capacitors. Compared with manual lead cutting or lead cutting by a single-strip conveyor mechanism, it can not only perform lead cutting on the entire strip simultaneously but also ensure the consistency of lead cutting dimensions. Among them, manual lead cutting can only be performed on a single piece, and the dimensions cannot be guaranteed to be consistent. The lead cutting by a single-strip conveyor mechanism also relies on manual continuous feeding and performs lead cutting on a single piece in sequence, resulting in low efficiency and inability to meet the requirements of large-batch product operations. This application relies on the mutual cooperation between various devices to solve the problems existing in manual lead cutting and lead cutting by a single-strip conveyor mechanism. The lead cutting efficiency is increased by 800% compared with manual cutting and 300% compared with lead cutting by a single-strip conveyor mechanism, effectively reducing production costs. It can be used for continuous lead cutting of the entire strip of tantalum capacitors in large batches, and at the same time, it can ensure that the product quality and appearance requirements are met, and the dimensions of the product after lead cutting are within the qualified range, thus achieving the goal of saving labor costs and improving production efficiency.

[0049] The above description is only a preferred embodiment of the present utility model, and thus cannot be used to limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the present utility model application and the content of the specification should still fall within the scope covered by the present utility model application.
