Description

Technical Field

[0001] This utility model relates to the field of ceramic cleaver detection technology, and in particular to a feeding device for detecting the holes in ceramic cleavers. Background Technology

[0002] Ceramic cleavers, also known as ceramic tips or capillary tubes, are used as welding needles in bonding machines. They are suitable for welding LEDs, IC chips, diodes, transistors, thyristors, surface acoustic waves, and other circuits. Using ceramic as a cleaver results in high hardness, high specific gravity, and fine grains, leading to high surface finish and high dimensional accuracy of the products.

[0003] Ceramic wedges have vertical holes inside to guide bonding wires (such as gold or copper wires) for bonding. During production, these holes need to be inspected to prevent defects. For example, Chinese Patent Publication No. CN214292577U discloses a feeding mechanism for grinding the outer diameter of ceramic wedges. This mechanism includes a feeding base, a moving component, and a feeding cylinder connected in sequence. The feeding base is a frame structure. The moving component drives the feeding cylinder to move. The feeding cylinder is equipped with a suction device for convenient feeding of the ceramic wedges. The feeding base is equipped with a feeding component for feeding the ceramic wedges. The feeding component feeds the ceramic wedges to the receiving position, and the moving component moves the suction device to the receiving position to pick up the ceramic wedges for feeding. This provides a feeding mechanism for grinding the outer diameter of ceramic wedges, facilitating the feeding of ceramic wedges.

[0004] In practice, the ceramic chopping knife is fed by a suction cylinder. However, considering that light sources and detection lenses need to be set at both ends during the feeding process, this feeding method may result in the end of the ceramic chopping knife being blocked, which makes it difficult for the detection device to detect the internal shaft hole of the ceramic chopping knife. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the shaft hole may be obstructed during the feeding process of ceramic cleavers, making shaft hole detection difficult. Therefore, this invention proposes a feeding device for detecting the shaft hole of ceramic cleavers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a feeding device for detecting the hole of a ceramic cleaver, including a detection platform. A feeding unit and a fixing frame are provided on the top of the detection platform. The fixing frame is provided with a detection unit, a conveying unit and a feeding unit on the side. The feeding unit includes a feeding component and a blocking component.

[0008] The material blocking component is located at the discharge end of the feeding unit and is used to intermittently supply material to the feeding component, so as to cooperate with the feeding component and the conveying unit to convey the ceramic chopping knife.

[0009] Furthermore, the feeding assembly includes a bracket, which is fixedly connected to the side of the fixed frame. A receiving seat is fixedly connected to the top of the bracket, and a movable component is provided. The movable component has a U-shaped structure and is fitted around the receiving seat through clearance grooves on both sides.

[0010] Furthermore, it also includes a driving component, which is fixedly connected to the side of the fixed frame. The two sides of the movable component are rotatably connected to the bracket through a pair of eccentric shafts. The shaft end of the driving component passes through the fixed frame and the bracket and is fixedly connected to the end of one of the eccentric shafts.

[0011] Furthermore, both the receiving seat and the top of the movable part are evenly distributed with several corresponding receiving grooves along the length direction. The receiving grooves are used to accommodate ceramic chopping knives. The receiving seat is fixedly connected to a guide plate on the discharge side above the conveying unit.

[0012] Furthermore, the material blocking assembly includes a baffle, and the feeding unit is rotatably connected to the baffle at the discharge port via a shaft and a torsion spring. The bottom of the baffle has an extension, and the movable part abuts against and moves the extension by circumferential rotation.

[0013] Furthermore, the detection lens of the detection unit is located on one side of the receiving seat.

[0014] The present invention provides a feeding device for detecting the holes of ceramic cleavers. The advantages of this device are as follows: the eccentric shaft driven by the driving component can rotate the movable component in a circular motion. The movable component can, on the one hand, move the extension part to make the baffle a receiving seat for intermittent feeding, and on the other hand, the movable component can rotate towards the discharge side of the receiving seat to cooperate with the receiving seat to intermittently convey the ceramic cleavers, so that the detection lens has enough time to react. In addition, the ceramic cleavers are horizontally housed in the receiving groove, and with both ends open, it can prevent the accumulation of ceramic cleavers and the shaft hole from being blocked, which would make it difficult to detect. The structure is simple and highly practical. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A feeding device for detecting ceramic cleaver holes includes a detection platform 1. A feeding unit 2 and a fixing frame 3 are provided on the top of the detection platform 1. A detection unit 4, a conveying unit 5 and a feeding unit are provided on the side of the fixing frame 3. The feeding unit includes a feeding component 6 and a blocking component 7.

[0023] The material blocking component 7 is located at the discharge end of the feeding unit 2 and is used to intermittently supply material to the feeding component 6, so as to cooperate with the feeding component 6 and the conveying unit 5 to convey the ceramic chopping knife.

[0024] In some embodiments, the feeding unit 2 is a vibratory feeder, and the conveying unit 5 includes a conveyor belt sleeved around a pair of rollers. The pair of rollers are rotatably connected to the fixed frame 3, and one of the rollers is connected to the shaft end of the drive motor.

[0025] Among them, the detection unit 4 is a detection lens, which is electrically connected to the detection terminal and is used to detect whether there are defects in the shaft hole of the ceramic chopping knife;

[0026] Furthermore, the specific structure of the feeding component 6 can be referenced from the step feeding mechanism in the prior art.

[0027] Furthermore, the feeding assembly 6 includes a bracket 61, which is fixedly connected to the side of the fixed frame 3. A receiving seat 62 is fixedly connected to the top of the bracket 61, and a movable part 63 is provided. The movable part 63 has a U-shaped structure and is fitted around the receiving seat 62 through two side clearance grooves 631.

[0028] It should be added that the bracket 61, the support seat 62 and the movable part 63 are all U-shaped. The bracket 61 is U-shaped to support the support seat 62 and the movable part 63 on one hand, and the eccentric shaft 65 is rotatably connected to the opposite surfaces at both ends of the bracket 61 on the other hand.

[0029] Specifically, under the action of the driving component 64 and the two eccentric shafts 65, the movable component 63 rotates circumferentially toward the receiving seat 62. On the one hand, the clearance groove 631 is provided to avoid jamming with the receiving seat 62. On the other hand, during the circumferential rotation, the ceramic cutting tool is intermittently conveyed through the receiving groove 66.

[0030] This means that the length of the ceramic cutting tool is greater than that of the receiving seat 62. Under the intermittent conveying action of the moving part 63, it is conveyed one by one along the receiving seat 62 to the next receiving groove 66. This prevents the shaft hole from being blocked, and at the same time, it can also use the gap time for the detection unit 4 to perform detection.

[0031] Furthermore, it also includes a drive component 64, which is fixedly connected to the side of the fixed frame 3. The two sides of the movable component 63 are rotatably connected to the bracket 61 through a pair of eccentric shafts 65. The shaft end of the drive component 64 passes through the fixed frame 3 and the bracket 61 and is fixedly connected to the end of one of the eccentric shafts 65. The drive component 64 is a motor.

[0032] More specifically, the top of both the receiving seat 62 and the movable part 63 has several corresponding receiving grooves 66 evenly distributed along the length direction. The receiving grooves 66 are used to accommodate ceramic chopping knives. The receiving seat 62 has a guide plate 67 fixedly connected to the material receiving unit 5 on the discharge side.

[0033] In general, the material blocking assembly 7 includes a baffle 71. The material feeding unit 2 is located at the discharge port and is rotatably connected to the baffle 71 via a shaft 72 and a torsion spring 73. The bottom of the baffle 71 has an extension 74. The movable member 63 abuts against and moves the extension 74 by circumferential rotation.

[0034] Specifically, the feeding unit 2 is a vibratory feeder. The vibratory feeder uses its internal spiral conveying groove to convey ceramic chopping knives under vibration. The ceramic chopping knives are conveyed along the discharge end of the vibratory feeder and are stopped by the baffle 71.

[0035] The movable part 63 rotates in a circle and moves the extension part 74. The extension part 74 drives the baffle 71 to rotate half a circle, and then the ceramic cutting blades feed the material one by one to prevent the material from piling up and blocking.

[0036] Finally, the detection lens of the detection unit 4 is located on one side of the receiving seat 62. The detection unit 4 also includes a light source, which further improves the detection effect of the detection lens through side illumination.

[0037] Working method: During operation, the ceramic chopping knife is placed in the vibratory feeder. Under the action of vibration, the ceramic chopping knife is conveyed along the discharge end of the vibratory feeder and stopped by the baffle 71.

[0038] The driving component 64 drives one of the eccentric shafts 65 to rotate. This eccentric shaft 65, in conjunction with another eccentric shaft 65, drives the movable component 63 to rotate. When the movable component 63 rotates, it actuates the extension 74, causing the extension 74 to drive the half-shaft of the baffle 71 to rotate, so that the ceramic chopping knives are fed into the receiving groove 66 one by one. In addition, when the movable component 63 rotates, it also intermittently conveys the ceramic chopping knives in the receiving groove 66 one by one. During the conveying process, the detection unit 4 detects the shaft hole of the ceramic chopping knives.

[0039] Then, the ceramic cutting tool is fed along the guide plate 67 and conveyed by the conveying unit 5.
