[0013] The present invention has the following beneficial effects: 1. The present invention cooperates with each other through symmetrical positioning guides and positioning foot-cutting mechanisms. The track flat grooves formed between the symmetrical positioning guides can support multiple LED lamps in a row and allow the pins to be inserted into the waste box. Then, the piston rod of the foot-cutting cylinder extends out, which will first push the positioning slide plate to slide and cooperate with the positioning strip to clamp and position the pins of the multiple LED lamps between the positioning gaps, thereby avoiding the loosening and displacement of the row of LED lamps when the foot-cutting blade punches the LEDs, thereby causing the phenomenon of dimensional deviation during punching. Then, the piston rod of the foot-cutting cylinder continues to extend to drive the foot-cutting blade to synchronously and quickly and accurately cut the pins of the multiple clamped and positioned pins. Since the positioning slide plate and the movable block are relatively slidably connected by the connecting spring and the positioning guide rod, when the movable block continues to push the foot-cutting blade to slide, the clamped and positioned positioning slide plate will not interfere with the foot-cutting blade, so that the positioning and foot-cutting mechanism can first clamp and position the pins of the row of LED lamps, and then perform fast and accurate foot-cutting processing.
[0014] 2. In the present invention, through the mutual cooperation of symmetrical positioning guide rails and clamping patch mechanisms, the piston rod of the pressurized cylinder can drive the balancing strip and the pressurized iron block to descend vertically, so that the buffer rubber strip can contact the LED lamp pushed into the track flat groove. As the piston rod of the pressurized cylinder continues to extend, the buffer rubber strip will push the row of LED lamps to move downward, so that the lamp body will be pressed and fit tightly to the plane of the track flat groove. At this time, the buffer spring will play a buffering and balancing role for the pressurized iron block, and the anti-deflection guide rod will slide on the balancing strip, thereby preventing the instantaneous pressure of the pressurized iron block from being too large and causing damage to the row of LED lamps. The role of the buffer rubber strip is to prevent the lamp body of the LED lamp from being damaged when the pressurized iron block applies pressure to the LED, thereby facilitating the correction of the deformed semi-finished product of the LED lamp to be pressed on a horizontal line, thereby realizing precise foot cutting processing of the LED lamp pins, so that the LED lamp pins after foot cutting can meet the customer's specification requirements of ±0.1mm.

The positioning strip 57 is fixed to the upper surface of the front box wall of the waste box 3, and the positioning strip 57 is aligned with the positioning slide plate 55. A recessed oblique groove 551 is formed on the upper surface of the end of the positioning strip 57 and the positioning slide plate 55 aligned with each other, and a positioning gap 552 is formed between the two recessed oblique grooves 551, and the positioning gap 552 is aligned with the track flat groove 41; In the scheme designed by the present invention, when the row of multiple LED lamps is pushed between the symmetrical positioning guide rails 4 and pressed and fitted to the plane of the track flat groove 41 by the pressing patch mechanism 7, the operator then steps on the pedal, and then through the solenoid valve group 92, the air inlet pipe 93, the air outlet pipe 91 and the adjustable joint 9 and other structures, the piston rod of the foot cutting cylinder 51 is extended, and then the movable block 53 will first drive the positioning slide plate 55 to slide in the sliding guide groove 31 toward the positioning strip 57 through the connecting spring 54 and the positioning guide rod 56, so that the recessed inclined groove 551 of the positioning slide plate 55 and the positioning strip 57 are close to each other to form a positioning gap 552 to clamp and position the pins of the row of multiple LED lamps that are deep into the waste box 3, and then the piston rod of the foot cutting cylinder 51 continues to extend, and the positioning guide rail 4 will be in the movable The movable block 53 slides out, and the connecting spring 54 is compressed, and then the movable block 53 will push the cutting blade 58 to perform precise cutting processing on the multiple pins clamped and positioned, and the cooperation of the sliding positioning slide plate 55 and the fixed positioning strip 57 is to add clamping force to the pins of the LED lamp in the horizontal direction to prevent the row of LED lamps from loosening and displacement when the cutting blade 58 punches the LED, which causes the phenomenon of dimensional deviation during punching; when the pins of the LED lamp are cut, the piston rod of the cutting cylinder 51 contracts, and the movable block 53 drives the cutting blade 58 and the positioning slide plate 55 to return to the initial position, and then the pressing patch mechanism 7 moves vertically upward to disengage and press the LED lamp after the cutting, so as to facilitate the LED lamp after the cutting to be pushed out from between the symmetrical positioning guide rails 4.
[0023] As an embodiment of the present invention, the adjustment support mechanism 6 includes a guide cylinder 61, a bracket guide rod 62, an adjustment screw 63, a fastening nut 64, a support strip 65 and a scale 66. Two groups of guide cylinders 61 are vertically fixed on the upper surface of the loading platform 1 and located on both sides of the waste box 3, and a bracket guide rod 62 is slidably inserted in each guide cylinder 61. The upper end surfaces of each group of two bracket guide rods 62 are respectively fixed to two symmetrical positioning guide rails 4, and the bottom end surfaces of each group of two bracket guide rods 62 extend downward to the bottom of the loading platform 1 and are connected to the support strip 65. An adjustment screw 63 is vertically arranged directly on the two bracket guide rods 62, and the top end surface of the adjustment screw 63 is connected to the loading platform 1 by a fastening nut 64. The bottom end of the adjustment screw 63 is connected to the support strip 65 by upper and lower fastening nuts 64. At least two groups of scales 66 are installed on the loading platform 1, and each scale 66 extends downward to be connected to the support strip 65. In the scheme designed by the present invention, the pin cutting equipment of the present invention can perform pin cutting processing of pins of different lengths according to customer requirements. Therefore, when it is necessary to adjust the height of the symmetrical positioning guide rail 4, first loosen the two fastening nuts 64 on the upper and lower surfaces of the support strip 65, and then push the support strip 65 upward or downward, so that the bracket guide rod 62 can push the symmetrical positioning guide rail 4 to move upward or downward synchronously. At this time, the operator can observe the scale line of the moving scale 66 at any time, and then can accurately adjust the distance between the positioning guide rail 4 and the positioning slide plate 55, so as to facilitate the pin cutting processing of pins of different lengths, and then fix the upper and lower fastening nuts 64 to the upper and lower surfaces of the support strip 65, so as to facilitate the support and fixation of the adjusted positioning guide rail 4.
[0024] As an embodiment of the present invention, the pressing patch mechanism 7 includes a fixed block 71, a positioning column 72, a positioning plate 73, a pressurized cylinder 74, a guide slide rod 75, a guide sleeve 76, a balancing strip 77, a buffer spring 78, an anti-deflection guide rod 79, a pressurized iron block 791 and a buffer rubber strip 792. The fixed block 71 is installed above the rear box wall of the waste box 3, and at least two positioning columns 72 are vertically fixed to the upper surface of the fixed block 71. The upper ends of at least two of the positioning columns 72 are fixed to the positioning plate 73 by nuts. A pressurized cylinder 74 is vertically fixed to the positioning plate 73, and the lower end surface of the piston rod of the pressurized cylinder 74 is connected to the A balancing strip 77 is connected, and at least two guide slide bars 75 are vertically connected to the upper surface of the balancing strip 77, and each guide slide bar 75 is slidably inserted into a guide sleeve 76 fixed on the positioning plate 73. The lower surface of the balancing strip 77 is connected to a pressurized iron block 791 through a symmetrical buffer spring 78. At least two anti-deflection guide rods 79 are vertically fixed to the upper surface of the pressurized iron block 791, and the two anti-deflection guide rods 79 respectively pass upward through the buffer spring 78 and are slidably connected to the balancing strip 77. A buffer rubber strip 792 is fixed to the lower surface of the pressurized iron block 791, and the buffer rubber strip 792 is aligned with the track flat groove 41. In the scheme designed by the present invention, when the pins of the row of LED lamps are pushed into the track flat groove 41 and in the appropriate position, the piston rod of the pressurized cylinder 74 is extended through the structures such as the solenoid valve group 92, the air inlet pipe 93, the air outlet pipe 91 and the adjustable joint 9, and then the balance strip 77 and the pressurized iron block 791 connected by the anti-deflection guide rod 79 are driven to move vertically downward, so that the buffer rubber strip 792 will contact the lamp body of the LED lamp. Therefore, as the piston rod of the pressurized cylinder 74 continues to extend, the buffer rubber strip 792 will push the row of LED lamps to move downward, so that the lamp bodies will be pressed and fit on the plane of the track flat groove 41, so that the deformed semi-finished product of the LED lamp can be corrected and pressed on a horizontal line, and the pins of the LED lamps can be accurately cut. When the pressure iron block 791 and the buffer rubber strip 792 push the LED lamps to quickly press and fit, the buffer spring 78 will play a buffering and balancing role for the pressure iron block 791, and the anti-deflection guide rod 79 will slide on the balance strip 77, thereby preventing the pressure iron block 791 from sliding. The instantaneous excessive pressure of block 791 may damage the row of LED lamps, and the buffer rubber strip 792 is used to prevent the LED lamp body from being damaged when the pressure iron block 791 applies pressure to the LED. When the row of LED lamps is cut, the piston rod of the cutting cylinder 51 drives the positioning slide plate 55 and the cutting blade 58 to return to their initial positions, and the piston rod of the pressurizing cylinder 74 contracts, which drives the pressure iron block 791 and the buffer rubber strip 792 to separate and pressurize the LED lamps through the balance strip 77 and the anti-deflection guide rod 79. This makes it easy to remove the LED lamp from the symmetrical positioning guide rail 4 after the feet are cut, and the symmetrical guide slide bar 75 slides up and down in the symmetrical guide sleeve 76, which can play a vertical guiding role for the lifting balance strip 77, preventing the pressure iron block 791 from being eccentric when pressed down, which will affect the precise cutting of the row of LED lamps. The cooperation of the positioning column 72 and the positioning plate 73 can vertically install the pressurized cylinder 74 between the symmetrical positioning guide rails 4, thereby realizing the vertical lifting and lowering of the balance strip 77 and the pressure iron block 791.
[0025] As an embodiment of the present invention, the fixing block 71 is fixed to the two side walls of the sliding guide groove 31 by screws, and the fixing block 71 is used to guide and limit the fitted cutting blade 58 and the positioning slide plate 55, and the left and right side walls of the waste box 3 are vertically provided with notch grooves 32, and the notch grooves 32 are aligned with the track flat groove 41; In the scheme designed by the present invention, the fixing block 71 is fixed to the sliding guide groove 31 by screws, which can not only provide suspended support for the positioning plate 73, but also guide and limit the sliding cutting blade 58 and the positioning slide plate 55, to prevent the sliding positioning strip 57 and the positioning slide plate 55 from detaching from or tilting on the waste box 3, thereby affecting the precise cutting processing of the pins by the cutting blade 58. The opening of the notch groove 32 on the waste box 3 makes it easy for the LED lamp to be cut to be pushed into the notch of the track flat groove 41, thereby achieving precise cutting processing of the pins of the LED lamp.
[0026] As an embodiment of the present invention, the symmetrical side of the positioning guide rail 4 is provided with an air-avoiding guide groove 42, and the air-avoiding guide groove 42 is located above the track flat groove 41, and the width of the air-avoiding guide groove 42 is greater than the width of the pressure iron block 791; In the scheme designed in the present invention, the design of the air-avoiding guide groove 42 makes it easy for the vertically descending pressurized iron block 791 and the buffer rubber strip 792 to accurately press the LED lamp down to fit it onto the plane of the track flat groove 41, thereby preventing the symmetrical positioning guide rails 4 from having a narrow distance, which causes the pressurized iron block 791 to be unable to push the row of LED lamps to be accurately pressed and fitted onto the plane of the track flat groove 41, thereby causing the row of LED lamps to be unable to be accurately cut.
[0027] As an embodiment of the present invention, the left end portion of the symmetrical positioning guide rail 4 is detachably installed with an inclined material guide ramp 8, and the end of the material guide ramp 8 that fits with the positioning guide rail 4 is lower than the notch of the track flat groove 41; and the setting of the inclined material guide ramp 8, when the LED lamp with the cut feet is pushed to the left and pushed out of the positioning guide rail 4, the pushed out LED lamp will fall smoothly into the collection frame placed on the left side of the stage 1, so that the LED lamp with the cut feet can be collected.
