Description

Technical Field

[0001] This utility model relates to the field of resistor stacking, and in particular to a chip resistor stacking machine. Background Technology

[0002] Surface mount resistor stacking machines are automated devices specifically designed to neatly stack surface mount resistors according to a specific pattern. They are widely used in component sorting, packaging, and quality inspection in the electronics manufacturing industry. Their core function is to orderly stack randomly or continuously fed surface mount resistors, facilitating subsequent counting, packaging, storage, or further processing.

[0003] Traditional stacking machines typically combine robotic arms and vacuum adsorption. The robotic arm moves a vacuum suction cup to the picking position, where the suction cup contacts the resistor surface. The vacuum system then activates, creating negative pressure to attract the resistor. The robotic arm then moves the resistor along a preset trajectory to the stacking platform, finally releasing it from the suction cup and placing it on the stacking reference position. However, this stacking method has a long adsorption, movement, and release cycle, making it difficult to match with high-speed production lines and resulting in low stacking efficiency. Furthermore, vacuum adsorption relies on the sealing of the surface of the surface-mount resistor, making it unsuitable for different resistor types.

[0004] Therefore, this utility model proposes a chip resistor stacking machine. Utility Model Content

[0015] Preferably, the receiving plate has a through groove; the through groove is located on the side of the receiving plate away from the conveyor belt.

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0021] like Figure 1-3 As shown in the figure, an embodiment of the present invention provides a chip resistor stacking machine, including a base 1, a conveyor belt 2, and a stacking assembly 3. The conveyor belt 2 is disposed on one side of the base 1 for conveying chip resistors. The stacking assembly 3 is disposed on the other side of the base 1; the stacking assembly 3 includes a receiving plate 311, a descending member, and an aligning member; the receiving plate 311 is connected to the conveyor belt 2; the descending member is disposed on both sides of the receiving plate 311 for controlling the intermittent descent of the receiving plate 311; the aligning member is disposed on the side of the receiving plate 311 away from the conveyor belt 2, and arranges the chip resistors neatly by pushing them.

[0022] Further explanation: The descending component includes two opposing mounting brackets 31; both mounting brackets 31 are fixedly mounted on the upper end of the base 1; a lead screw 32 is rotatably mounted on one mounting bracket 31, and a sliding rod 310 is mounted on the other mounting bracket 31; a receiving plate 311 is disposed between the lead screw 32 and the sliding rod 310. One side of the receiving plate 311 is threadedly connected to the lead screw 32, and the other side is slidably connected to the sliding rod 310. A grooved wheel 33 is fixedly mounted on the upper end of the lead screw 32; multiple radial grooves 34 are evenly distributed on the grooved wheel 33; an arc-shaped groove 35 is formed between each pair of adjacent radial grooves 34. A dial 36 is provided on one side of the grooved wheel 33; the dial 36 is rotatably connected to the mounting frame 31; the upper end of the dial 36 is provided with an arc-shaped plate 37 and a round pin 38; the arc-shaped plate 37 engages with the arc-shaped groove 35; the round pin 38 engages with the radial groove 34; the mounting frame 31 is also provided with a motor 39; the drive end of the motor 39 is connected to the lower end of the dial 36. The convex surface of the arc-shaped plate 37 matches the arc-shaped groove 35, and the concave surface is opposite to the radial groove 34. By starting the motor 39, the dial 36, the arc-shaped plate 37 and the round pin 38 can be driven to rotate. When the round pin 38 engages with the radial groove 34, it can drive the grooved wheel 33 and the lead screw 32 to rotate. When the arc-shaped plate 37 engages with the arc-shaped groove 35, it can limit the grooved wheel 33, thereby causing the grooved wheel 33 and the lead screw 32 to rotate intermittently, which in turn causes the receiving plate 311 to descend intermittently. The descending component works in conjunction with the conveyor belt 2 to smoothly transport the surface mount resistors on the conveyor belt 2 to the top of the receiving plate 311, where they are stacked sequentially. Compared to traditional stacking methods such as vacuum adsorption, this reduces waiting time, enables continuous stacking, and thus improves stacking efficiency. It can also accommodate surface mount resistors of different sizes and specifications, eliminating the need for frequent changes to the suction cups or adjustments to vacuum parameters, making it highly versatile.

[0023] Further explanation: The alignment component includes a fixing frame 314; both ends of the fixing frame 314 are fixedly connected to two mounting frames 31 respectively; a cylinder 315 is provided on the fixing frame 314; a connecting frame 316 is connected to the telescopic end of the cylinder 315; a second baffle 317 is slidably connected inside the connecting frame 316. The bottom end of the second baffle 317 abuts against the upper end of the receiving plate 311. When the receiving plate 311 descends, the second baffle 317 can descend with the receiving plate 311 under the influence of gravity, so that the lower end of the second baffle 317 always abuts against the receiving plate 311. A limiting strip 318 is fixedly provided at the upper end of the second baffle 317 to prevent the second baffle 317 from falling out of the connecting frame 316. A first baffle 313 is fixedly provided between the two mounting frames 31; the first baffle 313 is arranged on the side of the two mounting frames 31 near the conveyor belt 2; the first baffle 313 is configured to cooperate with the alignment component. By activating cylinder 315, the connecting frame 316 and baffle 2 317 can be pushed closer and closer to baffle 1 313 until the two sides of the chip resistor are against baffle 1 313 and baffle 2 317 respectively, thereby arranging the multi-layer chip resistor neatly and avoiding the multi-layer chip resistor from being scattered, which would make it difficult to remove and store.

[0024] To further explain, a through slot 312 is provided on the receiving plate 311; the through slot 312 is located on the side of the receiving plate 311 opposite to the conveyor belt 2. This allows workers to easily lift the multi-layer surface mount resistor from below through the through slot 312 to remove the surface mount resistor.

[0025] The working principle of this utility model is as follows: During operation, the conveyor belt 2 is first started to transport the surface mount resistors sequentially to the receiving plate 311. Then, the motor 39 is started, driving the dial 36, the arc plate 37, and the round pin 38 to rotate. When the round pin 38 engages with the radial groove 34, it can drive the groove wheel 33 and the lead screw 32 to rotate. When the arc plate 37 engages with the arc groove 35, it can limit the groove wheel 33, thereby causing the groove wheel 33 and the lead screw 32 to rotate intermittently, which in turn causes the receiving plate 311 to descend intermittently. This allows the surface mount resistors on the conveyor belt 2 to be smoothly transported to the top of the receiving plate 311 and stacked sequentially. After stacking, the cylinder 315 is started to push the connecting frame 316 and the second baffle 317 to gradually approach the first baffle 313 until the two sides of the surface mount resistors abut against the first baffle 313 and the second baffle 317 respectively, thereby aligning the multi-layer surface mount resistors. Finally, the baffle 317 is pulled upward from the connecting frame 316, and the multilayer chip resistor can be lifted from the bottom through the through slot 312 to remove the chip resistor.

[0026] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
