Description

Technical Field

[0001] The utility model relates to a diode lead shearing tool structure, belonging to the technical field of diode production equipment. Background Art

[0002] There is a production process called lead shearing in the diode production process. This process is to use a tool to cut off a part of the diode lead so that the diode lead reaches the specified height. The common diode shearing tool currently has two flat-plate structure upper and lower tools on both sides of the feeding track groove. There are several problems in the use of this structure of tool:

[0003] 1. The lower cutter of the shearing equipment is fixed, and the upper cutter opens and closes for shearing. Under the squeezing effect of the upper cutter, the diode lead is easily skewed to one side.

[0004] 2. The cut is uneven and the burrs are large when the lead is cut.

[0005] 3. The cutting accuracy can only be controlled within ±1mm (the customer requires ±0.5mm), and manual adjustment is required when adjusting different lead heights. Summary of the invention

[0006] The purpose of the utility model is to provide a diode lead cutting tool structure. The utility model adopts a V-shaped knife structure to ensure the flushness and precision of the cutting lead. The cutting precision can be controlled within ±0.2mm. The upper and lower knives are closed to the middle position at the same time, and the diode lead is evenly stressed to ensure that the diode lead is not skewed.

[0007] The technical solution of the utility model is as follows: a diode lead shearing tool structure comprises a guide plate located above a feeding tray, a guide rail is arranged on the side of the guide plate, the guide rail is slidably engaged with two sliding blocks, a tool mounting plate is fixedly connected to the bottom of each sliding block, an upper tool and a lower tool of a V-shaped structure are respectively fixed to adjacent ends of the two tool mounting plates, the openings of the upper tool and the lower tool are arranged facing each other, a cylinder mounting plate is respectively fixed to both ends of the guide plate, a tool driving cylinder is installed on each cylinder mounting plate, and push rods of the two tool driving cylinders are respectively connected to the two sliding blocks.

[0013] 1. Upper and lower knives with V-shaped structures are arranged facing each other. Both the upper and lower knives are driven by corresponding starting cylinders, so that the upper and lower knives are closed to the middle position at the same time. During the lead cutting process, the diode lead is evenly stressed to ensure that the diode lead will not be skewed.

[0015] 3.

[0016] 4. The diode limiting device is provided to press the diode socket during the cutting process to prevent the diode from shaking during the lead cutting process, thereby ensuring the cutting accuracy.

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0024] Embodiment of the utility model: a diode lead cutting tool structure, such as Figure 1-4 As shown, it includes a guide plate 2 located above the feed tray 1, and two guide rails 3 are arranged on the side of the guide plate 2. The guide rails 3 are slidably engaged with two sliding blocks 4. A horizontal tool mounting plate 5 is fixedly connected to the bottom of each sliding block 4, and the adjacent ends of the two tool mounting plates 5 are respectively fixed with an upper tool 6 and a lower tool 7 of a V-shaped structure, that is, one tool mounting plate 5 is installed with an upper tool 6, and the other tool mounting plate 5 is installed with a lower tool 7, and the openings of the upper tool 6 and the lower tool 7 are arranged opposite to each other, and a cylinder mounting plate 8 is fixed to each of the two end ends of the guide plate 2, and a tool driving cylinder 9 is installed on each cylinder mounting plate 8, and the push rods of the two tool driving cylinders 9 are respectively connected to the two sliding blocks 4.

[0025] During the lead cutting process, the diode to be cut is sent by the conveying device to the diode fixed position on the feeding tray 1. The feeding tray 1 rotates to turn the diode to be cut to the cutting position and then stops rotating. At this time, the push rods of the two tool driving cylinders 9 are pushed out, driving the sliding block 4 to move in a straight line along the guide rail 3. The upper tool 6 and the lower tool 7 move towards each other, so that the lead of the diode to be cut is inserted into the V-shaped mouth of the tool. The lead cutting work can be completed through the interaction between the upper tool 6 and the lower tool 7, and then the tool driving cylinder 9 is recovered, the upper tool 6 and the lower tool 7 are separated, and the feeding tray 1 continues to rotate for the next cutting work.

[0026] A lead screw lift 10 is vertically arranged beside the guide plate 2, and the slider of the lead screw lift 10 is fixedly connected to the vertical plate 11, and the bottom of the vertical plate 11 is fixedly connected to the other side of the guide plate 2. During the operation of the lead screw lift 10, its motor drives the lead screw to rotate, thereby driving the slider to move up and down along the lead screw straight line, and the slider can drive the vertical plate 11 to move synchronously during the up and down movement, and the vertical plate 11 will drive the guide plate 2 to move synchronously, thereby driving the upper tool 6 and the lower tool 7 to move up and down, and the upper tool 6 and the lower tool 7 move downward to correspond to the height of the lead wire shearing, and after the upper tool 6 and the lower tool 7 move downward to the shearing height, the upper tool 6 and the lower tool 7 move toward each other again to achieve the shearing of the lead wire.

[0027] Two sets of upper cutters 6 and lower cutters 7 are respectively arranged on the two cutter mounting plates 5. There are two sets of upper cutters 6 and lower cutters 7. Because each station of the feeding tray 1 conveys two diodes at a time, two sets of upper cutters 6 and lower cutters 7 are correspondingly arranged. The leads of two diodes can be cut at one time, thereby improving the processing efficiency of diode lead cutting. The current equipment can only cut the leads of one diode at a time. In comparison, the processing efficiency of the utility model is increased by 1 times.

[0028] The upper tool 6 is arranged on the outside of the feeding tray 1, and a diode limit device is arranged on the top surface of the frame below the upper tool 6. The diode limit device includes a limit cylinder mounting plate 12, and a limit device mounting plate 13 is arranged on the limit cylinder mounting plate 12. The limit device mounting plate 13 is fixedly connected to the push rod of the limit cylinder 14 on the back of the limit cylinder mounting plate 12, and a diode limit block is arranged at the front end of the limit device mounting plate 13. A U-shaped limit card 15 is arranged at the front end of the diode limit block. The limit card 15 is located directly below the upper tool 6, and the bottom of the limit cylinder mounting plate 12 is fixedly connected to the push rod of the upward cylinder 16.

[0029] During the process of cutting the diode lead, a diode limit device is provided to prevent the diode from shaking. During the lead cutting process, the limit cylinder 14 is first extended to push the limit device mounting plate 13 forward, so that the diode lead is clamped into the limit card 15, and then the upward cylinder 16 is recovered, driving the limit cylinder mounting plate 12, the limit device mounting plate 13 and other structures to move downward together, so that the limit card 15 is pressed on the top surface of the diode socket, thereby pressing and fixing the diode to prevent the diode from shaking, and then the upper cutter 6 and the lower cutter 7 complete the lead cutting work. After the lead cutting is completed, each component can be reset by reverse action.

[0030] The limit cards 15 are provided with two, because each station of the feeding tray 1 delivers two diodes each time, so two limit cards 15 are provided accordingly.
