Description

Technical Field

[0001] The utility model relates to a calibration detection structure, in particular to a calibration detection structure of a ball planting fixture, and belongs to the technical field of chip ball planting equipment. Background Art

[0002] During the chip implantation process, a implantation fixture is required to operate the chip. Figure 1 and Figure 2 As shown, before ball implantation, it is necessary to first place the carrier plate 1 horizontally on the carrier 2, and then place multiple chips 3 into multiple cavities on the carrier plate 1, and then proceed to the next step of ball implantation for the chips 3. Among them, when the carrier plate 1 is placed on the carrier 2, the carrier plate 1 is placed on the carrier 2 using a ball implantation fixture 4. During the placement process, the carrier plate 1 and the carrier 2 are both in a horizontal state. The ball implantation fixture 4 is in an inverted U-shape, including a top plate 411 and side plates 412 arranged on both sides of the top plate 411, and a feed groove 413 for placing the carrier plate 1 is arranged on the inner side of each of the side plates 412. As shown Figure 3 and Figure 4 As shown, when placing the carrier plate 1, first place the two side edges of the carrier plate 1 into the feed grooves 413 on both sides of the ball planting fixture 4 respectively. Since the thickness H1 of the carrier plate 1 is less than the groove height H2 of the feed groove 413, after the two side edges of the carrier plate 1 are placed into the feed groove 413, the lower surface of the carrier plate 1 contacts an inner side of the feed groove 413, and a spacing L1 is left between the upper surface of the carrier plate 1 and the other inner side of the feed groove 413. After placing the two side edges of the carrier plate 1 into the feed groove 413, the ball planting fixture 4 is controlled to move downward, thereby driving the carrier plate 1 to move downward and place it on the carrier 2. In order to position the carrier plate 1 after it is placed on the carrier 2, as shown in FIG. Figure 1 and Figure 3 As shown, a plurality of positioning holes 111 are opened on the carrier plate 1, and a plurality of positioning PIN needles 211 are arranged on the carrier 2 at positions corresponding to the positioning holes 111. When the carrier plate 1 is moved down and placed on the carrier 2, the positioning PIN needles 211 are passed through the positioning holes 111 so that the position of the carrier plate 1 on the carrier 2 can be positioned.

[0003] However, if Figure 5As shown, in the prior art, due to the manufacturing process, some positioning holes 111 of the carrier plate 1 have defects such as burrs, so when the ball planting fixture 4 drives the carrier plate 1 to move downward, some positioning PIN needles 211 can be inserted into the positioning holes of the carrier plate 1 (such as the positioning PIN needle 211 on the left side of the figure), while some positioning PIN needles 211 are blocked by the defects such as burrs in the positioning holes 111 and cannot be inserted into the positioning holes of the carrier plate 1 (such as the positioning PIN needle 211 on the right side of the figure). As a result, during the downward movement of the ball planting fixture 4, the carrier plate 1 will appear in a tilted state with a certain tilt angle. In this way, if the ball planting fixture 4 continues to be pressed downward, the carrier plate 1 and the ball planting fixture 4 will be damaged.

[0004] After searching, no identical or similar patent documents have been found.

[0005] In summary, how to design a calibration detection structure for a bulb planting fixture so that it can detect the horizontal state of the carrier plate during the placement process to avoid the carrier plate from tilting during the placement process, thereby causing damage to the equipment, improving production efficiency, and reducing production costs are technical problems that need to be solved urgently.

DETAILED DESCRIPTION

[0032] The technical solution of the utility model is further elaborated in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Embodiment 1: Figures 6 to 9 As shown, a calibration detection structure of a bulb planting fixture includes a plurality of telescopic probe mechanisms 5 arranged on the inner bottom surface of the top plate 411 of the carrier plate 1, the lower end of the telescopic probe 511 of each telescopic probe mechanism 5 is exposed from the inner bottom surface of the top plate 411 and extends into the spacing L1, and the end position of the lower end of each telescopic probe 511 is on the same horizontal plane B, and a spacing L2 is left between the horizontal plane B and the upper surface of the carrier plate 1 located in the feed groove 413, and a sensor 6 is further arranged in the top plate 411 and above the upper end of each telescopic probe 511, when the telescopic probe 511 moves upward, the upper end of each telescopic probe 511 can extend into the sensor 6 and cooperate with the sensor 6 to trigger an alarm signal, thereby performing calibration detection.

[0034] The calibration test process is as follows: Fig.10 As shown in FIG. 1 , after the two sides of the carrier plate 1 are placed in the feed grooves 413 on both sides of the ball planting fixture 4, a gap L2 is left between the lower end of the telescopic probe 511 and the upper surface of the carrier plate 1 located in the feed groove 413. At this time, the ball planting fixture 4 is controlled to move downward, thereby driving the carrier plate 1 to move downward together, and the carrier plate 1 is placed on the carrier 2, as shown in FIG. Fig.11As shown, when the positioning PIN needles 211 on some carriers 2 are blocked by defects such as burrs in the positioning holes 111 of the carrier plate 1, the carrier plate 1 is tilted, so that the side of the carrier plate 1 tilted upward contacts the lower end of the telescopic probe 511, thereby pushing the telescopic probe 511 upward, causing the upper end of the telescopic probe 511 to move upward and extend into the sensor 6, so that the telescopic probe 511 cooperates with the sensor 6 to perform calibration detection and send out an alarm signal. After the operator finds the alarm signal, the machine is stopped immediately, and the defects such as burrs in the positioning holes 111 of the carrier plate 1 are handled, and then the work is continued. In this way, the horizontal state of the carrier plate 1 can be detected in real time, and the tilt of the carrier plate during the placement process is avoided, thereby avoiding the occurrence of equipment damage problems, improving production efficiency, and reducing production costs.

[0035] like Fig. 9 and Fig.12 As shown, the telescopic probe mechanism 5 includes a mounting block 512 in addition to the telescopic probe 511. The telescopic probe 511 passes through the mounting block 512 and can move up and down along the mounting block 512. An upper limit stopper 513 is provided on the telescopic probe 511 passing through the mounting block 512 and located at the upper end of the telescopic probe 511. A lower limit stopper 514 is provided on the telescopic probe 511 passing through the mounting block 512 and located at the lower end of the telescopic probe 511. A return spring 515 is also provided between the lower limit stopper 514 and the mounting block 512. The return spring 515 can be a compression spring. A mounting groove 414 is provided on the inner bottom surface of the top plate 411 of the carrier plate 1. By installing the mounting block 512 of the telescopic probe mechanism 5 into the mounting groove 414, the telescopic probe mechanism 5 is provided on the inner bottom surface of the top plate 411. Here, the size of the mounting groove 414 can be set to match the mounting block 512, so that the mounting block 512 is pressed tightly in the mounting groove 414 by interference; the mounting block 512 can also be installed in the mounting groove 414 by a connector. The sensor 6 is arranged on the inner bottom surface of the mounting groove 414. The sensor 6 can be a U-shaped photoelectric sensor.

[0036] like Figure 6 As shown, in the present embodiment, a total of four telescopic probe mechanisms 5 are provided, and the four telescopic probe mechanisms 5 are respectively provided at the four corner positions of the inner bottom surface of the top plate 411. With this arrangement, no matter which positioning hole has defects such as burrs that cause the carrier plate to tilt, it can be detected in time and in real time, further avoiding the occurrence of equipment damage problems.

[0037] Embodiment 2: Fig.13 and Fig.14As shown, compared with the first embodiment, the difference is that: a metal sheet 7 is also provided in the top plate 411 and above the upper end of each telescopic probe 511, and the metal sheet 7 and the carrier 2 are respectively connected to the positive and negative poles of the power supply; in the process of placing the carrier plate 1 on the carrier 2, when the carrier plate 1 is tilted so that the telescopic probe 511 moves up and contacts the metal sheet 7, an electrical circuit is formed between the carrier 2, the carrier plate 1, the telescopic probe 511, the metal sheet 7 and the power supply, and the calibration detection structure of the ball planting fixture also includes an electrical signal detection device for detecting the electrical circuit. In this embodiment, the metal sheet 7 is connected to one of the positive and negative poles of the power supply through the wire 8.

[0038] During the process of placing the carrier plate 1 on the carrier 2, when the carrier plate 1 is tilted, the side of the carrier plate 1 tilted upward contacts the lower end of the telescopic probe 511, thereby pushing the telescopic probe 511 upward, causing the upper end of the telescopic probe 511 to move upward and contact the metal sheet 7. At this time, the carrier 2 also contacts the carrier plate 1, thereby forming an electrical circuit between the carrier 2, the carrier plate 1, the telescopic probe 511, the metal sheet 7 and the power supply, and the electrical signal detection device detects the electrical signal of the electrical circuit and sends an alarm signal. The operator immediately stops the machine after discovering the alarm signal, and continues to work after dealing with defects such as burrs in the positioning holes of the carrier plate.

[0039] In summary, the utility model can detect the horizontal state of the carrier plate in real time through structural design, avoid the tilt of the carrier plate during the placement process, thereby avoiding the occurrence of equipment damage problems, improving production efficiency, and reducing production costs. By designing a telescopic probe and a U-shaped photoelectric sensor, the telescopic probe is used in conjunction with the U-shaped photoelectric sensor to send out an alarm signal for calibration detection, so that the horizontal state of the carrier plate can be detected in real time. By designing a telescopic probe and a metal sheet, an electrical circuit is formed between the carrier, the carrier plate, the telescopic probe, the metal sheet and the power supply, so that the horizontal state of the carrier plate can be detected in real time.

Those skilled in the relevant technical field can make various changes or modifications without departing from the spirit and scope of the utility model.
