Description

Technical Field

[0001] This utility model relates to the field of semiconductor testing and packaging equipment technology, and in particular to a turret-type robotic arm for controlling the excess amount of the carrier tape. Background Technology

[0002] In the field of automated production and packaging of electronic components, carrier tape reeling equipment is the core equipment for packaging precision components such as IC chips. Its operating efficiency and stability directly affect production benefits and cost control. The Mi 20 turret robot, as a key component of the reeling equipment, uses a carrier tape conveyor module that precisely controls motor movements through a driver to automate the transport of carrier tape from the carrier reel to the conveyor belt, providing continuous and stable process assurance for the precise embedding of IC chips into carrier tape pockets. However, traditional Mi 20 reeling equipment has a significant technical shortcoming in carrier tape margin management—it lacks real-time carrier tape margin monitoring and control functions.

[0003] Specifically, existing equipment, during continuous tape and reel packaging, cannot dynamically sense whether the remaining amount of carrier tape in the reel is sufficient to complete the full packaging of the current roll. This deficiency leads to a high reliance on manual inspection and experience-based judgment on the production floor. Operators must frequently interrupt equipment operation to confirm the carrier tape remaining amount, increasing labor costs. Furthermore, human negligence or delayed response can cause the carrier tape to run out before the roll is full, resulting in a large amount of loose, unfinished tape. Such scraps require additional manpower for rewinding, significantly extending product delivery cycles and increasing material loss and equipment downtime due to secondary processing. Ultimately, this leads to increased production costs, decreased customer satisfaction, and severely restricts the factory's lean management and market competitiveness.

[0004] Therefore, this application develops a turret-type robotic hand to control the load margin, in order to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this invention is to provide a turret-type robotic arm for controlling the carrier tape allowance, so as to solve the problem that the carrier tape allowance cannot be detected in the existing technology.

[0006] The technical solution of this utility model is: a turret-type robotic arm for controlling the carrying capacity, comprising:

[0007] A turret, wherein one side of the turret is wound with a carrier belt around the center of the turret;

[0008] A fixed bracket is attached to the other side of the turret opposite to the carrier belt to support the turret.

[0009] The remaining amount detection component includes an adjustment bracket, a detection window, and a detection module. The detection window is opened on the surface of the turret to expose a local area of ​​the carrier tape. One end of the adjustment bracket is fixed to the fixed bracket, and the other end extends towards the detection window, so that the output end of the detection module installed on the adjustment bracket corresponds to the position of the detection window, for detecting the remaining amount of carrier tape.

[0010] Preferably, the adjusting bracket includes a clamping part and a connecting rod. The clamping part is detachably clamped onto the fixed bracket. The connecting rod has a limiting end and an arbitrary end. The limiting ends of the two connecting rods are coaxially connected by a knob, so that the two connecting rods can only rotate relative to each other in one direction. The arbitrary ends of the two connecting rods are respectively connected to the clamping part and the detection module by a universal ball, so that the arbitrary ends swing relative to the clamping part and the detection module in any direction.

[0011] Preferably, on the mating surfaces of the two adjacent limiting ends, a plurality of limiting teeth are evenly distributed along the edge contour, and the limiting teeth of the two limiting ends are distributed in an alternating manner.

[0012] Preferably, the detection window is located close to the center of the turret, and the remaining amount of carrier tape between the center of the turret and the center of the detection window is greater than the amount required for a single product.

[0013] Preferably, the height of the detection window is greater than the length of one of the connecting rods, but less than the sum of the lengths of the two connecting rods.

[0014] Preferably, the knob has threaded sections with different thread directions on its rotating rod. Push rods are installed in the two limiting ends via threaded connections. Each of the two push rods has a first abutting surface inclined towards the corresponding limiting end on its adjacent side. An abutting rod is provided along the length of the connecting rod to abut the push rod. One end of the abutting rod abuts against the corresponding universal ball joint, and the other end has a second abutting surface that fits against the first abutting surface, allowing the push rod and the abutting rod to move in two mutually perpendicular directions.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] (1) The detection window is opened on the surface of the turret, exposing a local area of ​​the carrier tape, providing a direct detection channel for the detection module, enabling the detection module to obtain real-time status information of the carrier tape, avoiding the problem of inaccurate detection of the remaining amount due to the carrier tape being completely wrapped, and greatly improving the detection accuracy.

[0017] (2) The detection window is close to the center of the turret, and the remaining amount of carrier tape between the center of the turret and the center of the detection window is greater than the amount required for a single product. Even if the detection module indicates that the remaining amount is insufficient, the remaining amount can still complete the manufacturing of a product, thus avoiding waste of resources.

[0018] (3) The connecting rod has a limiting end and an arbitrary end. The limiting end is coaxially connected by a knob to limit the relative rotation direction and achieve preliminary constraint and control. The arbitrary end is connected to the clamping part and the detection module through a universal ball, so that the arbitrary end can swing in any direction. The detection module can flexibly adjust the position and angle according to the actual situation and different turrets to ensure that it is in the best detection position and ensure the accuracy and reliability of the detection.

[0027] The present invention will be further described in detail below with reference to specific embodiments:

[0028] like Figures 1-3As shown, a turret-type robotic arm for controlling the remaining amount of carrier tape includes a turret 1, a fixed bracket 2, and a remaining amount detection component 3. One side of the turret 1 is wound with carrier tape, serving as the raw material for the product, centered on its own center. The fixed bracket 2 is installed on the opposite side of the turret 1, supporting the turret 1. The remaining amount detection component 3 includes an adjusting bracket 31, a detection window 32, and a detection module 33. The detection window 32 is located on the surface of the turret 1, exposing a local area of ​​the carrier tape and providing a direct detection channel for the detection module 33. This allows the detection module 33 to directly acquire real-time status information of the carrier tape, avoiding the problem of inaccurate remaining amount detection when the carrier tape is completely wrapped, thus greatly improving detection accuracy. The detection module 33 is supported by the adjusting bracket 31, one end of which is fixed to the fixed bracket 2, and the other end extends towards the detection window 32. This ensures that the output end of the detection module 33 on the adjusting bracket 31 corresponds to the position of the detection window 32, thereby enabling the detection of the remaining amount of carrier tape.

[0029] Specifically, the detection module 33 uses a photoelectric sensor, which is mounted on the adjustment bracket 31. Its output precisely corresponds to the detection window 32 on the surface of the turret 1. When the device is running, the photoelectric sensor works continuously, emitting a specific signal to the detection window 32. If there is carrier tape at the detection window 32, the surface of the carrier tape will reflect the signal emitted by the photoelectric sensor. After receiving the reflected signal, the photoelectric sensor processes it through its internal circuitry to determine that the carrier tape is present, and the system maintains normal operation without any notification. If there is no carrier tape at the detection window 32, the photoelectric sensor cannot receive the reflected signal because there is no object to reflect it. In this case, the photoelectric sensor will feed back the situation to the device's control system, which will then trigger an alert mechanism to promptly remind the staff that the carrier tape is insufficient, so that the staff can take appropriate measures as soon as possible, such as replacing the carrier tape, to ensure the normal operation of the device.

[0030] In this embodiment, the detection window 32 is located near the center of the turret 1, and the remaining amount of carrier tape between the center of the turret 1 and the center of the detection window 32 is greater than the amount of carrier tape required during the production or use of a single product. This ensures that even if the detection module 33 provides a prompt, the remaining amount is still sufficient to complete the manufacturing of a product. If the remaining amount is insufficient to meet the needs of a single product, it will lead to the scrapping of a single product, resulting in a significant waste of resources.

[0031] like Figures 2-3As shown, the adjusting bracket 31 includes a clamping part 311 and a connecting rod 312. The clamping part 311 is detachably fixed to the fixed bracket 2. This allows the adjusting bracket 31 to be flexibly installed or removed from the fixed bracket 2 according to actual needs, facilitating maintenance, replacement, or position adjustment. The connecting rod 312 has a limiting end 313 and an arbitrary end 314. The limiting ends 313 of the two connecting rods 312 are coaxially connected by a knob 4, which restricts the relative rotation direction of the two connecting rods 312, allowing them to rotate relative to each other only in a specific direction, thus achieving preliminary constraint and control in the rotation direction. The arbitrary ends 314 of the two connecting rods 312 are respectively connected to the clamping part 311 and the detection module 33 via a universal ball joint. The omnidirectional ball connection gives the arbitrary end 314 a great degree of freedom of movement, allowing it to swing in any direction relative to the clamping part 311 and the detection module 33. This enables the detection module 33 to flexibly adjust its position and angle according to the actual situation such as the carrier tape position and detection angle, ensuring that the detection module 33 is always in the optimal detection position, thereby guaranteeing the accuracy and reliability of the detection of the carrier tape allowance.

[0032] To better adapt to different turret 1 and different detection window 32 positions, the length of the connecting rod 312 was designed so that the height of the detection window 32 is greater than the length of one connecting rod 312 but less than the sum of the lengths of the two connecting rods 312. By adjusting the position of the two connecting rods 312, the detection can be adapted to different detection conditions, ensuring that the output end of the detection module 33 corresponds to the position of the detection window 32. This ensures that the detection module 33 is always in the optimal detection position and is not affected by the rotation of the turret 1 or other factors, thereby guaranteeing the reliability and stability of the carrier tape allowance detection results.

[0033] Specifically, such as Figure 4 As shown, the knob 4 has threaded sections with different thread directions on its rotating rod. Inside the limiting ends 313 of the two connecting rods 312, push rods 5 are installed by threaded connection. On the adjacent end faces of the two push rods 5, there are first abutting surfaces 51 that are inclined toward the corresponding limiting ends 313. Along the length of the connecting rod 312, there is an abutting rod 6 that abuts against the push rod 5. One end of the abutting rod 6 abuts against the corresponding universal ball, and the other end is provided with a second abutting surface 61 that fits against the first abutting surface 51 of the push rod 5.

[0034] When the knob 4 is rotated, due to the action of the threaded sections with different thread directions on the rotating rod, the two push rods 5 will move along the axial direction of the rotating rod. Because the first abutting surface 51 of the push rod 5 and the second abutting surface 61 of the abutting rod 6 are in contact with each other and are inclined, the axial movement of the push rod 5 will push the abutting rod 6, causing the abutting rod 6 to move in a direction perpendicular to the moving direction of the push rod 5, thereby abutting against the universal ball and fixing the universal ball, so that the entire clearance detection is in a stable state and will not deviate.

[0035] Furthermore, such as Figures 5-6 As shown, on the adjacent mating surfaces of the two limiting ends 313, multiple limiting teeth 315 are evenly distributed along the edge contour. The limiting teeth 315 of the two limiting ends 313 are distributed in an interlaced manner. When the two limiting ends 313 are mated together, the limiting tooth 315 of one limiting end 313 will be embedded into the gap between the adjacent limiting teeth 315 of the other limiting end 313, forming a mutually interlocking state. This makes the two limiting ends 313 more tightly and stably mated, restricting their relative movement in the direction perpendicular to the mating surface and enhancing the stability of the connection structure.

They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
