Description

Technical Field

[0001] The utility model relates to the technical field of electronic component processing, in particular to a fixing fixture of a wire cutting machine used for pin needle processing. Background Art

[0002] PIN is a metal material used in connectors to conduct electricity (signals). It is usually made of "tungsten carbide", that is, hard alloy. PIN blanks usually need to be cut into small PIN segments of the required length using a wire cutting machine. The PIN blanks fed into the wire cutting machine are usually in a strip-shaped structure, such as Figure 6 shown.

[0003] A Chinese utility model patent discloses a fixed-distance feeding and cutting pin needle device (Announcement No.: CN213530602U). After the pin needle belt is compressed by the pusher claw and the pressing pad, the feeding cylinder needs to be moved to complete the feeding. This requires the provision of a linear guide rail and a slider for smooth feeding. The design of the linear guide rail increases the occupied volume of the entire device. In addition, when the feeding cylinder feeds the material, its feeding frequency is periodic, and the linear guide rail needs to reciprocate once to complete one feeding. Therefore, the feeding is not continuous enough, which will affect production efficiency when used on the production line. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 A wire cutting machine fixing fixture for pin needle processing includes a fixing plate 1, and side plates 2 are symmetrically arranged on both sides of the fixing plate 1. The fixing plate 1 is a cubic structure, and grooves and fixing ports for connecting with the side plates 2 are opened at symmetrical positions on both sides. It is fixed above the side plates 2. By setting the grooves and fixing ports, it can better match the side plates, which is conducive to saving space, and by setting the fixing plate 1, the two side plates 2 can maintain a certain distance from each other, thereby providing a certain space for the transportation of the PIN square blank strip 10.

[0026] In the embodiment of the present utility model, a clamping cylinder 3 is provided through the side panel 2, and the side panel 2 is an "L"-shaped plate body, with a hole position 1 for connecting with the fixed plate 1 on the top, a hole position 2 for installing the clamping cylinder 3 in the middle, and a plurality of hole positions 3 for fixing with the wire cutting machine at the bottom. By setting the side panel 2 as an "L"-shaped structure, not only can the clamping wheel 7 be provided with movement space, but also the installation is convenient.

[0027] In the embodiment of the present utility model, a bracket 4 is fixed to the output shaft of the clamping cylinder 3. The bracket 4 can move axially along the output shaft of the clamping cylinder 3. The bracket 4 is of a "C" - shaped structure, and through - holes for fixing bearings 5 are provided in both the upper and lower parts thereof. A rotating shaft 6 is fitted inside the bearing 5. The lower end of the rotating shaft 6 is fixed to a clamping wheel 7. A plurality of threaded holes are provided in the lower part of the bracket 4 for fixing a motor bracket 8. The clamping wheel 7 is rotatably installed on the bracket 4. The clamping wheel 7 is driven to rotate by a motor 9. Through this arrangement, certain power can be provided for the clamping wheel 7, thereby realizing the feeding of the PIN - guide billet strip 10.

[0028] In the embodiment of the present utility model, the clamping wheel 7 includes two flange parts 701 arranged up and down. An annular recessed part 703 is provided between the two flange parts 701. The flange part 701 is of a disc - shaped structure. A connecting part 702 is provided at the center position of the circular end face of the flange part 701. The connecting part 702 located above is mutually matched with the rotating shaft 6, and the connecting part 702 located below is mutually matched with the output shaft of the motor 9. The two arranged flange parts 701 can hold the PIN - guide on the PIN - guide billet strip 10. The arranged recessed part 703 can make space for the fixing frame in the middle of the PIN - guide billet strip 10, so as to match the outer contour of the PIN - guide billet strip 10. The connecting part 702 above and the connecting part 702 below are respectively in a mutually - matching manner with the rotating shaft 6 and the output shaft of the motor 9, which is convenient for disassembling the clamping wheel 7, thus facilitating the later maintenance work.

[0029] In the embodiment of the present utility model, the motor 9 is fixed inside the motor bracket 8. The motor bracket 8 is fixed to the lower part of the bracket 4. The motor bracket 8 is of a "C" - shaped structure, and a protrusion is provided on its upper part. A plurality of through - holes are provided through the protrusion for fixing the motor bracket 8 and the bracket 4 by bolts. This design is for adaptive adjustment.

[0030] In the embodiment of the present utility model, an infrared counting device 12 is fixedly installed on the inner wall of the bracket 4. The infrared counting device 12 is close to the trough of the recessed part 703 in the front - view angle of the bracket 4. Figure 5 As shown, an infrared counting device 12 is fixedly installed on the inner wall of the bracket 4. The infrared counting device 12 emits infrared rays perpendicular to the inner wall of the bracket 4. When the PIN - pins on the strip pass through the infrared path of the infrared counting device 12, the infrared rays are blocked. Each blockage forms a signal, thereby performing counting. Since the straight - line distance between the inner wall of the bracket 4 and the PIN - pin strip is close enough, the measurement result is more accurate, reducing the interference of foreign objects.

[0031] As Figure 5As shown, the infrared counting device 12 is close to the trough of the recessed portion 703 in the front view of the bracket 4, and the state of the clamping wheel 7 can be monitored at the same time through the infrared counting device 12. When the clamping wheel 7 is offset, it will lead to poor transmission and clamping conditions, affecting production quality. When the clamping wheel 7 is offset, it will block the infrared counting device 12, causing the infrared path of the infrared counting device 12 to be in a blocked state. By detecting the working state of the infrared counting device 12, the state of the clamping wheel 7 can be monitored. The advantage of being set at the trough is that the clamping wheel 7 can block the infrared counting device 12 regardless of whether it is tilted upward or tilted downward.

[0032] When the utility model is in use, the fixed furniture is fixed to the pin needle thread cutting machine by means of bolts passing through the hole three below the two side panels 2, and the clamping cylinder 3 is connected to the pneumatic control system of the pin needle thread cutting machine, and the motor 9 is connected to the electronic control system of the pin needle thread cutting machine. Then the utility model starts to be used, and the two clamping wheels 7 can be moved toward each other through the action of the clamping cylinder 3, thereby clamping the PIN material strip 10. After the clamping wheels 7 clamp the PIN material strip 10, the speed of the motor 9 is controlled by the electronic control system to drive the rotation of the clamping wheels 7. The feeding speed of the PIN material strip 10 can be adjusted by the speed of the motor 9. Since the clamping wheels 7 are used for clamping and feeding, continuous feeding can be achieved. At the same time, since the clamping wheels 7 are in a rotating state when clamping and feeding, no displacement will occur, thereby saving a certain amount of space.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
