Description

Technical Field

[0001] This invention relates to the field of semiconductor bead cutting technology, and more specifically, to a bead connection detection device and bead cutting equipment. Background Technology

[0002] Currently, with the development of the semiconductor industry and the advancement of technology, people have increasingly higher requirements for the production efficiency and product quality of semiconductor products. After the semiconductor lead cutting process is completed, the product needs to be inspected for quality to determine whether there are any lead cutting defects. If there are residual leads in the product, it indicates that the lead cutting is incomplete and the product quality is poor, thus indicating that the lead cutting punch has broken teeth or the lead cutting die has abnormal cutting. If there are no leads in the product, it indicates that the lead cutting is complete and the product quality is good.

[0003] Currently, the common method for detecting ribs in products is to add a vision inspection camera after the rib cutting mold. However, vision inspection cameras are expensive, resulting in high inspection costs. Furthermore, since they determine whether there are residual ribs in the product by capturing images, false detections can occur even with small plastic burrs, leading to low detection accuracy and poor inspection results.

[0004] In view of this, designing and manufacturing a rib-connecting detection device and rib-cutting equipment with high detection accuracy and low detection cost is particularly important in semiconductor production. Summary of the Invention

[0033] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0034] Please refer to the reference. Figures 1 to 4 This invention provides a lead-cutting device (not shown) for performing lead-cutting operations on semiconductors. Its lead-connection detection device 100 can accurately detect lead-cutting defects in the product 200, with high detection accuracy, good detection effect, and can effectively reduce detection costs, making it practical and reliable.

[0035] The lead-cutting equipment includes a lead-cutting device (not shown) and a lead-connection detection device 100. The lead-cutting device is positioned in front of the lead-connection detection device 100, and the lead-cutting device and the lead-connection detection device 100 are arranged sequentially along the semiconductor feeding direction. The lead-cutting device is used to cut leads in the semiconductor to form a product 200 with lead-cutting grooves 210. The lead-connection detection device 100 is used to detect whether there are residual leads in the product 200 to determine whether the product 200 has lead-cutting defects, thereby determining whether the quality of the product 200 is qualified. Furthermore, when the lead-connection detection device 100 detects residual leads in the product 200, it also indicates that the lead-cutting punch in the lead-cutting device has broken teeth or that the lead-cutting device is malfunctioning. In this case, the lead-cutting device needs to be repaired to ensure the production quality of subsequent products 200.

[0036] The rib-connecting detection device 100 includes a frame 110, a drive mechanism 120, a detection rod 130, a transmission mechanism 140, and a sensor 150. The transmission mechanism 140 is movably mounted on the frame 110. One end of the transmission mechanism 140 is connected to the detection rod 130, and the other end cooperates with the sensor 150. The transmission mechanism 140 can move relative to the frame 110 under the drive of the detection rod 130 to transmit signals to the sensor 150. The drive mechanism 120 is mounted on the frame 110 and is used to feed the product 200 towards the detection rod 130, causing the product 200 to shift relative to the detection rod 130. The detection rod 130 is used to extend into the rib cutting groove 210 of the product 200 and slides with the rib cutting groove 210. When there are connecting ribs remaining in the rib cutting groove 210, the detection rod 130 can drive the transmission mechanism 140 to move under the resistance of the connecting ribs, so that the sensor 150 can detect that the product 200 has a rib cutting defect. The detection accuracy is high, the detection effect is good, and the detection cost can be effectively reduced. It is practical and reliable.

[0037] Specifically, when the drive mechanism 120 drives the product 200 to move relative to the detection rod 130, the free end of the detection rod 130 extends into the rib cutting groove 210 and slides within the rib cutting groove 210. The rib cutting groove 210 can limit and guide the free end of the detection rod 130. During this process, if there are connecting ribs remaining in the rib cutting groove 210, the connecting ribs will block the sliding of the free end of the detection rod 130 and push the free end of the detection rod 130 towards the direction of exiting the rib cutting groove 210, so that the detection rod 130 drives the transmission mechanism 140 to move, thereby causing the sensor 150 to detect that the product 200 has a rib cutting defect. During this process, if there are no connecting ribs in the rib cutting groove 210, the free end of the detection rod 130 will slide smoothly within the rib cutting groove 210, the transmission mechanism 140 will not move, and the sensor 150 will not detect that the product 200 has a rib cutting defect.

[0038] It should be noted that the product 200 has multiple cutting grooves 210 and multiple detection rods 130. These multiple detection rods 130 are arranged parallel and spaced apart on the transmission mechanism 140, with each detection rod 130 slidingly engaging with one cutting groove 210. The multiple detection rods 130 work together to simultaneously detect whether any remaining connecting ribs are present in the multiple cutting grooves 210, thereby improving detection efficiency and enhancing the detection effect.

[0039] The transmission mechanism 140 includes a mounting plate 141 and a transmission rod 142. A detection rod 130 is connected to one side of the mounting plate 141, and the transmission rod 142 is connected to the other side of the mounting plate 141. The transmission rod 142 cooperates with a sensor 150. The detection rod 130 can drive the transmission rod 142 to move via the mounting plate 141, so that the transmission rod 142 transmits a signal to the sensor 150, causing the sensor 150 to detect a cutting defect in the product 200. Specifically, the mounting plate 141 is disposed on a horizontal plane, the detection rod 130 extends downwards from the mounting plate 141, and the transmission rod 142 extends upwards from the mounting plate 141. Both the detection rod 130 and the transmission rod 142 are arranged in a vertical direction.

[0040] In this embodiment, sensor 150 is a photosensitive sensor with a photosensitive port 151. The position of transmission rod 142 corresponds to the position of photosensitive port 151. Detection rod 130 is used to drive transmission rod 142 to move via mounting plate 141, thereby blocking or opening photosensitive port 151. Specifically, when there are connecting ribs remaining in the cutting groove 210 of product 200, the connecting ribs will push detection rod 130 upward during the sliding process of detection rod 130, thereby driving transmission rod 142 upward via mounting plate 141. During this process, transmission rod 142 blocks photosensitive port 151, allowing sensor 150 to determine that there are connecting ribs remaining in cutting groove 210, thus determining that product 200 has a cutting defect and that the cutting device is abnormal. At this time, sensor 150 will issue an alarm and control the entire cutting equipment to pause, prompting personnel to inspect the cutting device and rework the current product 200.

[0041] However, this is not the only option. In other embodiments, sensor 150 can also be a pressure sensor. The pressure sensor is equipped with a contact, and a transmission rod 142 abuts against the contact. A detection rod 130 is used to drive the transmission rod 142 to move via the mounting plate 141 to apply pressure to the contact. Specifically, when there are connecting ribs remaining in the cutting groove 210 of product 200, the connecting ribs will push the detection rod 130 upward during the sliding process of the detection rod 130, thereby driving the transmission rod 142 to move upward via the mounting plate 141. During this process, the transmission rod 142 applies pressure to the contact, so that the pressure sensor can determine that there are connecting ribs remaining in the cutting groove 210, thereby determining that product 200 has a cutting defect and that the cutting device is malfunctioning.

[0042] Mounting plate 141 includes a fixed plate 143 and a pad 144 that are overlapped and interconnected. The fixed plate 143 is connected to the pad 144 by screws. The fixed plate 143 has a stepped hole 145. A boss 131 is provided at the end of the detection rod 130. The boss 131 is located within the stepped hole 145 and abuts against the pad 144. The boss 131 is clamped between the fixed plate 143 and the pad 144. The fixed plate 143 and the pad 144 work together to fix the position of the boss 131, thereby fixing the position of the detection rod 130. A transmission rod 142 is connected to the side of the pad 144 away from the fixed plate 143. The detection rod 130 can drive the pad 144 upward via the boss 131, thereby driving the transmission rod 142 upward.

[0043] In this embodiment, the frame 110 is provided with a positioning plate 111, which is parallel to the mounting plate 141. The positioning plate 111 has an interconnected mounting groove 112 and a limiting hole 113. The sensor 150 is installed in the mounting groove 112, and the transmission rod 142 is slidably engaged with the limiting hole 113. The transmission rod 142 can slide within the limiting hole 113, and the limiting hole 113 can guide and limit the transmission rod 142. Specifically, when there are residual connecting ribs in the rib cutting groove 210 of the product 200, the detection rod 130 drives the transmission rod 142 to extend into the mounting groove 112 through the mounting plate 141, and blocks the photosensitive port 151 of the sensor 150.

[0044] It is worth noting that the connecting rod detection device 100 also includes a first return spring 160, a pin 170, a second return spring 180, a guide post 190, and a guide sleeve 191. A limiting ring 146 is provided around the circumference of the transmission rod 142. The first return spring 160 is sleeved on the outside of the transmission rod 142. One end of the first return spring 160 abuts against the limiting ring 146, and the other end abuts against the bottom wall of the mounting groove 112. The first return spring 160 can apply elastic force to the limiting ring 146, so that the limiting ring 146 moves downward, thereby driving the transmission rod 142, the mounting plate 141, and the detection rod 130 to move downward synchronously, thereby realizing the reset function of the transmission mechanism 140.

[0045] Specifically, the first return spring 160 is always in a compressed state, and the first return spring 160 always applies a downward elastic force to the limiting ring 146, so that the transmission rod 142 has a downward tendency to move. When there are connecting ribs remaining in the rib cutting groove 210 of the product 200, the detection rod 130 overcomes the elastic force of the first return spring 160 and drives the transmission rod 142 to move upward; when there are no more connecting ribs in the rib cutting groove 210 of the product 200, the detection rod 130, the mounting plate 141 and the transmission rod 142 are reset under the action of the elastic force of the first return spring 160.

[0046] Furthermore, the pin 170 is fixedly installed on the mounting plate 141 and connected to the positioning plate 111 via the second return spring 180. The second return spring 180 can apply a spring force to the mounting plate 141, causing the mounting plate 141 to move downwards, thereby driving the transmission rod 142 and the detection rod 130 to move downwards synchronously, thus realizing the reset function of the transmission mechanism 140. The second return spring 180 and the first return spring 160 work together to improve the reset efficiency and ensure the reset effect.

[0047] Similarly, the second return spring 180 is always in a compressed state, and it always applies a downward elastic force to the mounting plate 141, so that the mounting plate 141 tends to move downward. When there are connecting ribs remaining in the rib cutting groove 210 of the product 200, the detection rod 130 overcomes the elastic force of the second return spring 180 and drives the mounting plate 141 to move upward; when there are no more connecting ribs in the rib cutting groove 210 of the product 200, the detection rod 130, the mounting plate 141, and the transmission rod 142 are reset under the action of the elastic force of the second return spring 180.

[0048] In this embodiment, there are four pins 170 and four second return springs 180. The four pins 170 are arranged in a rectangular array on the mounting plate 141. Each pin 170 is connected to the positioning plate 111 through a second return spring 180. The four second return springs 180 work together to further improve the reset effect. However, this is not the only embodiment. In other embodiments, the number of pins 170 and two return springs 180 can be two or six. The number of pins 170 and two return springs 180 is not specifically limited.

[0049] It should be noted that the guide sleeve 191 is fixedly installed inside the positioning plate 111, and the guide post 190 is fixedly connected to the mounting plate 141 and slidably engages with the guide sleeve 191. The guide post 190 can slide relative to the guide sleeve 191, and the guide sleeve 191 can limit and guide the guide post 190 to ensure the stability of the mounting plate 141 during the lifting process. Specifically, both the guide post 190 and the guide sleeve 191 extend vertically to ensure that the mounting plate 141, the detection rod 130, and the transmission rod 142 all move upward or downward vertically.

[0050] In this embodiment, there are four guide posts 190 and four guide sleeves 191. The four guide posts 190 are arranged in a rectangular array on the mounting plate 141. Each guide post 190 is slidably engaged with one guide sleeve 191. The four guide posts 190 and four guide sleeves 191 work together to further improve the guiding effect. However, this is not the only embodiment. In other embodiments, the number of guide posts 190 and guide sleeves 191 can be two or six. The number of guide posts 190 and guide sleeves 191 is not specifically limited.

[0051] Please refer to the reference. Figure 1 and Figure 5 The drive mechanism 120 includes a drive motor 121, a drive wheel 122, and a driven wheel 123. The drive motor 121 is mounted on the frame 110 and is connected to the drive wheel 122, enabling the drive motor 121 to rotate. The driven wheel 123 is rotatably mounted on the frame 110. The drive wheel 122 and driven wheel 123 are used to clamp the side strip 220 of the product 200. Specifically, during the rotation of the drive wheel 122 by the drive motor 121, the drive wheel 122 drives the side strip 220 of the product 200 forward through friction, thereby driving the entire product 200 forward to achieve the feeding function of the product 200. During this process, the side strip 220 of the product 200 drives the driven wheel 123 to rotate through friction. The drive wheel 122 and driven wheel 123 work together to ensure the stability of the product 200 feeding process.

[0052] In this embodiment, there are two drive mechanisms 120. The two drive mechanisms 120 are arranged opposite to each other on both sides of the detection rod 130. Both drive mechanisms 120 are used to drive the product 200 forward. The detection rod 130 is used to slide relative to the cutting groove 210 of the product 200 during the feeding process, so as to realize the detection function of cutting defects of the product 200.

[0053] The rib-connecting detection device 100 provided in this embodiment of the invention has a transmission mechanism 140 movably mounted on a frame 110. One end of the transmission mechanism 140 is connected to a detection rod 130, and the other end cooperates with a sensor 150. A drive mechanism 120 is mounted on the frame 110 and is used to drive the product 200 to feed towards the detection rod 130. The detection rod 130 is used to extend into the rib-cutting groove 210 of the product 200 and slides with the rib-cutting groove 210. When there are ribs remaining in the rib-cutting groove 210, the detection rod 130 can drive the transmission mechanism 140 to move under the resistance of the ribs, so that the sensor 150 can detect that the product 200 has a rib-cutting defect. Compared with existing technologies, the rib-cutting detection device 100 provided by the present invention, due to the use of a detection rod 130 for extending into the rib-cutting groove 210 of the product 200 and a transmission mechanism 140 cooperating with the sensor 150, can accurately detect rib-cutting defects in the product 200, with high detection accuracy, good detection effect, and can effectively reduce detection costs, making it practical and reliable. This results in low detection costs and a high yield rate for rib-cutting equipment.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
