Description

Technical Field

[0001] The utility model belongs to the technical field of chip sorting equipment, and in particular relates to a device for selecting chips with irreversible pins. Background Art

[0002] The chip packaging process includes processes such as pin cutting, bending, and inspection. The inspection process includes the process of detecting pin deformation. Pin deformation is divided into recoverable pin deformation and irreversible pin deformation. Existing detection devices can only detect deformed pins but cannot distinguish between the two. After chips with deformed pins are detected, most of them need to be manually sorted for a second time. The chip pins that can be restored are sent to the correction device for correction to make them qualified, thereby reducing waste and saving costs.

[0003] However, manual selection in this process is time-consuming and labor-intensive, and has low efficiency. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a device for selecting chips with irreversible pin deformation, which can automatically select chips with irreversible pin deformation, has a simple structure and high efficiency.

[0005] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0006] A pin-unrecoverable chip selection device is provided on both sides of a conveyor belt and is spaced apart from a visual inspection mechanism on one side of the conveyor belt, comprising:

[0007] The material stopper is located on one side of the conveyor belt and is telescopically arranged perpendicular to the conveying direction of the conveyor belt to intercept chips with deformed pins;

[0008] The ejection member is located on the other side of the conveyor belt and is arranged opposite to the material blocking member. The ejection member includes a movable plate arranged to move perpendicular to the conveying direction of the conveyor belt. The movable plate is L-shaped. The vertical part of the movable plate is provided with a first cylinder, and ejection rods are arranged in an array along the length direction of the horizontal part of the movable plate. The ejection rods are arranged vertically, and the number of ejection rods is one more than the number of chip pins. When the material blocking member intercepts the chip with deformed pins, the pins of the chip are staggered with the ejection rods, which are used to eject the chip with irreversible pins.

[0009] Furthermore, the material blocking member includes a U-shaped blocking rod, the internal opening distance of the U-shaped blocking rod is greater than the width in the chip conveying direction, and the length of the arm on one side of the U-shaped blocking rod facing the visual inspection mechanism is greater than the length of the arm on the other side. The two arms of the U-shaped blocking rod form a selection area, and the horizontal part of the U-shaped blocking rod is connected to the second cylinder, and the second cylinder is installed on the first bracket.

[0010] Furthermore, an inclined surface is provided at one end of the inner side of one side arm of the U-shaped barrier rod.

[0011] Furthermore, adjustment plates are provided parallel and at intervals on the movable plate, the ejection rod is arranged along the array of adjustment plates, the lower end of the ejection rod is passed through the movable plate, and a limit plate is provided at the lower end of the ejection rod, a spring is passed through the ejection rod, one end of the spring abuts against the movable plate, and the other end abuts against the adjustment plate, the first cylinder is installed on the second bracket, a support rod is provided on the second bracket, a triangular plate is provided at one end of the support rod, the oblique side of the triangular plate faces the adjustment plate, and the triangular plate is located below the conveyor belt.

[0012] Furthermore, a roller is provided on one side of the adjustment plate.

[0013] The beneficial effects of the present invention are:

[0014] A blocking piece is used to intercept chips with deformed pins, and then an ejection rod is used to move from one end of the chip pins to the other end along both sides of the chip pins. If the deformation of the chip pins reaches an irreversible state, the ejection rod is blocked by the chip pins, and under the continuous push of the ejection rod, the chip with irreversible pins is pushed out of the conveyor belt. If the pins can be restored, the ejection rod passes from both sides of the pins, and the chip remains motionless in the selection area, thereby automatically picking out the chip with irreversible pins. The structure is simple and the efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] like Figures 1-9 As shown, this embodiment provides a device for selecting a chip with irreversible pins, comprising a blocking member 10 and a pushing member 20 respectively arranged on both sides of a conveyor belt 1, for Figure 10 The irreversible chip 3 is picked out. The device is located on one side of the visual inspection mechanism 2. When the visual inspection mechanism 2 detects a chip 3 with a deformed pin, it starts the device to intercept the chip 3 with a deformed pin and pick out the irreversible chip 3.

[0029] Specifically, such as Figure 1 、 Figure 4 As shown, the material stopper 10 is located on one side of the conveyor belt 1 and is telescopically arranged along the conveying direction perpendicular to the conveyor belt 1 to intercept the chip 3 with deformed pins and prevent the next chip 3 from continuing to be conveyed forward.

[0030] like Figure 1-Figure 3 、 Figure 5-Figure 7As shown, the ejector 20 is located on the other side of the conveyor belt 1 and is arranged opposite to the material stopper 10. The ejector 20 includes a movable plate 21. The movable plate 21 has an L-shaped structure. An ejector rod 212 is arranged in an array along the length direction of the movable plate 21. The ejector rod 212 is vertically arranged and perpendicularly connected to the horizontal portion of the movable plate 21. The number of ejector rods 212 is one more than the number of pins of the chip 3. When in use, the ejector rod 212 is staggered with the pins of the chip 3, and the pins of the chip 3 are located between two adjacent ejector rods 212, which is used to eject the chip 3 whose pins cannot be restored from the conveyor belt 1. The horizontal portion of the movable plate 21 faces the conveyor belt 1, and the vertical portion of the movable plate 21 is away from the conveyor belt 1. A first cylinder 211 is provided on the side, and the output end of the first cylinder 211 is connected to the vertical portion of the movable plate 21, which is used to control the movable plate 21 to move in a direction perpendicular to the conveyor belt 1.

[0031] The specific operation process is as follows:

[0032] The chips 3 are arranged and conveyed in sequence along the length direction of the conveyor belt 1, and the pins of the chip 3 are perpendicular to the length direction of the conveyor belt 1 and extend out of the conveyor belt 1. A pressure plate is set on the top of the conveyor belt 1 so that the packaging part of the chip 3 is located between the pressure plate and the conveyor belt 1 to prevent the chip 3 from flipping out of the conveyor belt 1 during transportation.

[0033] The visual inspection mechanism 2 is located on the side where the pins of the chip 3 extend out of the conveyor belt 1, and is used to detect the pins of the chip 3. When a chip 3 with deformed pins is detected, the obtained information is reported to the upper machine position, and the upper machine position controls the blocking member 10 and the ejection member 20 in sequence, so that the blocking member 10 moves toward the direction of the conveyor belt 1, thereby intercepting the chip 3 with deformed pins, and then the first cylinder 211 pushes the movable plate 21 to move toward the conveyor belt 1, so that the ejection rod 212 is inserted along both sides of the pins of the chip 3. When the deformation of the chip pins is greater than the distance between the pins of the chip 3 and the ejection rod 212, it is an irreversible chip 3. The ejection rod 212 pushes the chip 3 out of the conveyor belt 1 under the obstruction of the deformed pins of the chip 3, thereby picking out the irreversible chip 3.

[0034] Specifically, such as Figure 1 、 Figure 4As shown, the material blocking member 10 includes a U-shaped blocking rod 11, a second cylinder, and a first bracket 13. The U-shaped blocking rod 11 is horizontally arranged, and the arms on both sides thereof are perpendicular to the length direction of the conveyor belt 1 and pass through the conveyor belt 1. The internal opening distance of the U-shaped blocking rod 11 is greater than the width of the chip 3 in the conveying direction, so that the two arms of the U-shaped blocking rod 11 form a picking area. The length of the arm of the U-shaped blocking rod 11 on one side facing the visual inspection mechanism 2 is greater than the length of the arm on the other side. The horizontal part of the U-shaped blocking rod 11 is located on the outside of the conveyor belt 1, and the output end of the second cylinder 12 is connected to the outside of the U-shaped blocking rod 11. When intercepting, the second cylinder 12 is used to push the U The horizontal part of the U-shaped baffle 11 moves toward the conveyor belt 1, so that the longer arm on one side of the U-shaped baffle 11 enters the conveyor belt 1 first, so that the chip 3 with deformed pins enters the selection area, and intercepts the chip 3 that has not entered the selection area. The arm on the other side of the U-shaped baffle 11 then enters the conveyor belt 1, and intercepts the chip 3 with deformed pins entering the selection area, and limits the chip 3 with deformed pins, so that the ejection rod 212 is aligned with the pins of the chip 3 corresponding to the two adjacent ejection rods 212. The first bracket 13 is installed on one side of the conveyor belt 1, and the second cylinder 12 is installed on the first bracket 13.

[0035] Preferably, in order to prevent the U-shaped baffle 11 from entering the conveyor belt 1 and the arm of the U-shaped baffle 11 facing the visual inspection mechanism 2 from interfering with the chip 3 with deformed pins entering the selection area, a slope 111 is provided at one end of the inner side of the arm of one side of the U-shaped baffle 11.

[0036] Specifically, such as Figure 3 、 Figure 5-Figure 6As shown, in order to increase the service life of the ejection rod 212 and prevent the ejection rod 212 from being deformed due to the impact force between the ejection rod 212 and the conveyor belt 1 after multiple uses, an adjustment plate 22 is provided on the movable plate 21 in parallel and at intervals, so that the ejection rod 212 is arranged in an array along the length direction of the adjustment plate 22, so that the adjustment plate 22 and the ejection rod 212 thereon become one body, and the lower end of the ejection rod 212 is passed through the movable plate 21, so that the lower end of the ejection rod 212 and the movable plate 21 are vertically slidably arranged, and a limit plate 213 is provided at the lower end of the ejection rod 212 extending out of the movable plate 21 to control the ejection The lower end of the rod 212 is limited, and a spring 214 is provided on the push rod 212. The lower end of the spring 214 abuts against the top surface of the movable plate 21, and the upper end abuts against the bottom surface of the adjustment plate 22. The first cylinder 211 is mounted on the second bracket 215. The second bracket 215 is provided on the other side of the conveyor belt 1. A support rod 216 is mounted on the second bracket 215. One end of the support rod 216 extends toward the other side of the conveyor belt 1 and is located at the bottom of the conveyor belt 1. A group of spaced triangle plates 217 are provided at one end of the support rod 216, and the hypotenuse of the three-ply plate 217 is directed toward the adjustment plate 22. When the first cylinder 211 pushes the movable plate 21 toward the conveyor belt 1, the corresponding push rod 212 moves toward the chip 3 along the two sides corresponding to the pins of the chip 3, thereby pushing the irreversible chip 3 out of the conveyor belt 1, as shown in FIG. Figure 7-Figure 9 As shown, before the ejection rod 212 approaches the outside of the conveyor belt 1, the adjustment plate 22 moves downward along the inclined surface of the triangular plate 217 under the obstruction of the triangular plate 217, so that the adjustment plate 22 drives the ejection rod 212 to move vertically downward and move to the bottom of the conveyor belt 1. At this time, the spring 214 is compressed. After the irreversible chip 3 is pushed out, the first cylinder 211 enters the return stroke, thereby resetting the ejection rod 212 and moving the U-shaped blocking rod 11 out of the conveyor belt 1.

[0037] When the ejection rod 212 passes along both sides of the pins corresponding to the chip 3 with deformed pins, the chip 3 is a recoverable chip. At this time, the chip 3 will not be pushed out of the conveyor belt 1. The ejection rod 212 moves vertically downward with the adjustment plate 22 to the bottom of the conveyor belt 1 to avoid the chip 3 with deformed pins. At this time, the U-shaped blocking bar 11 moves out of the conveyor belt 1 to allow the chip 3 with deformed pins to enter the next process. After the next chip 3 with deformed pins enters the selection area, the first cylinder 211 enters the return stroke, so that the ejection rod 212 is vertically upward under the restoring force of the spring 214, and under the action of the first cylinder 211, the ejection rod 212 moves along both sides of the pin in the direction away from the conveyor belt 1. If it is an irreversible chip 3, the chip 3 will be pulled out of the conveyor belt 1. If it is a recoverable chip 3, the ejection rod 212 passes along both sides of the pin.

[0038] Preferably, Figure 6As shown, in order to make the adjustment plate 22 move smoothly under the obstruction of the triangular plate 217, a roller 221 is provided on the side of the adjustment plate 22 facing the inclined surface of the triangular plate 217, so that the sliding friction between the adjustment plate 22 and the triangular plate 217 is changed to rolling friction.

It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
