Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic component processing and manufacturing technology, and more specifically, to an easy-to-operate chip resistor testing and packaging machine. Background Technology
[0002] In surface mount technology (SMT) for electronic components such as surface mount resistors, the resistors are typically pre-assembled on paper tape, forming a "tape roll" package for easy handling by automated pick-and-place machines. However, most packaging machines only leave a very narrow observation slit above the paper tape, making it difficult to manually or mechanically fine-tune and calibrate the surface mount resistors. Manual or mechanical pulling or resetting of a single resistor often requires stopping the machine and disassembling the local structure, resulting in low efficiency and poor reliability. Furthermore, the lack of paper tape clamping and limiting mechanisms, along with the absence of dedicated support and clamping structures, makes the paper tape prone to shifting, leading to increased detection errors and significantly reduced transmission efficiency, among other problems. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide an easy-to-operate chip resistor testing and packaging machine to solve the above problems.
[0004] The present invention adopts the following solution:
[0005] This application provides an easy-to-operate chip resistor testing and packaging machine, including a paper feeding mechanism, a paper pressing and limiting mechanism, and a moving and yielding mechanism. The paper feeding mechanism is provided with a strip-shaped track, which continuously feeds a strip of paper laterally within the track. The paper pressing and limiting mechanism is provided with a pressing board, which is used to overlap and press the front section of the strip-shaped paper on the strip-shaped track. The moving and yielding mechanism includes a toggle switching component disposed on the rear section of the strip-shaped paper on the strip-shaped track. The strip-shaped track has a recessed area in the rear section that exposes the chip resistor inside the strip-shaped paper. The toggle switching component is configured to be operablely switchable between an initial position and a pulled position, thereby further adjusting the chip resistor in the exposed area.
[0006] As a further improvement, the toggle switch component covers the exposed area in the initial position, exposes the exposed area in the pulled position, and can adaptively switch back to the initial position after a retraction operation.
[0007] As a further improvement, the toggle switching assembly includes a positioning post disposed on the outside of the track, a toggle plate that can move movably relative to the positioning post in the position switching direction, an operating post attached to the toggle plate, and a return spring that is elastically connected between the operating post and the positioning post.
[0008] As a further improvement, the actuating plate is provided with a guide groove, and the positioning post is fitted into the guide groove to allow the actuating plate to move freely relative to the positioning post through the guide groove.
[0009] As a further improvement, the reset spring is positioned above the guide groove and is always in a stretched state.
[0010] As a further improvement, the chip resistors are arranged in a dotted pattern on the upper side of the strip paper tape, and are correspondingly hidden within the strip track, appearing only in the exposed area.
[0011] As a further improvement, the exposed area is in the shape of a trapezoidal groove, and the top of the actuating plate is provided with a trapezoidal protrusion that is adapted to and engages with the exposed area.
[0012] As a further improvement, the strip track provides power to the strip paper tape via an external rewinding mechanism.
[0013] As a further improvement, the pressure plate is adjustablely positioned on the outside of the track to accommodate strips of paper of different widths.
[0014] As a further improvement, the pressing plate is an L-shaped sheet metal part, and the pressing operation is performed on its short side.
[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:
[0016] 1. The easy-to-operate chip resistor testing and packaging machine of this application, through the cooperation of the paper conveying mechanism and the strip track, can continuously convey the carrier belt in the transverse direction, ensuring the continuity of the packaging and testing process and improving production efficiency.
[0017] 2. The paper pressing and limiting mechanism uses a pressing plate to overlap and press the strip paper at the front of the track, ensuring that the paper strip is always flat and accurately positioned when entering the detection / calibration, reducing detection errors caused by deviation.
[0018] 3. An exposed area for surface mount resistors is set at the rear of the paper tape. By toggling the switching component, the surface mount resistors can be freely switched between the initial position and the pulled position. This allows for fine-tuning and calibration of the surface mount resistors without stopping the machine for disassembly and assembly, significantly improving the flexibility and ease of maintenance of the equipment. Furthermore, the exposed area allows electrical probes or vision systems to directly contact or observe the surface mount resistors, which is beneficial for more accurate measurement of resistance values or appearance conditions, reducing the misjudgment rate and improving product yield.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.
[0023] Example
[0024] Combination Figures 1 to 2 This embodiment provides an easy-to-operate chip resistor detection packaging machine, including a paper feeding mechanism, a paper pressing and limiting mechanism, and a moving and yielding mechanism. The paper feeding mechanism has a strip track 1, which continuously feeds a strip of paper A laterally within the track. The paper pressing and limiting mechanism has a corresponding pressing plate 2, which is used to overlap and press the front section of the strip of paper A on the strip track 1. The moving and yielding mechanism includes a toggle switching component 3 disposed on the rear section of the strip of paper A on the strip track 1. The strip track 1 has a recessed area at the rear section that exposes the chip resistor B inside the strip of paper A. The toggle switching component 3 is configured to be operablely switchable between an initial position and a pulled position, thereby further adjusting the chip resistor B in the exposed area.
[0025] The easy-to-operate patch resistor testing packaging machine described above, through the paper conveying mechanism and the strip track 1, can continuously convey the carrier belt in the transverse direction, ensuring the continuity of the packaging and testing process and improving production efficiency.
[0026] The paper pressing and limiting mechanism uses the pressing plate 2 to overlap and press the strip paper A at the front of the track, ensuring that the paper strip is always flat and accurately positioned when entering the detection / calibration, thus reducing detection errors caused by deviation.
[0027] In particular, an exposed area for the chip resistor B is provided at the rear of the paper tape. By toggling the switching component 3, the chip resistor B can be freely switched between the initial position and the pulled position. This allows for fine-tuning and calibration of the chip resistor B without stopping the machine for disassembly and assembly, significantly improving the flexibility and ease of maintenance of the equipment. Furthermore, the exposed area allows electrical probes or vision systems to directly contact or observe the chip resistor B, which is beneficial for more accurate measurement of resistance values or appearance, reducing the misjudgment rate and improving product yield.
[0028] In this embodiment, the toggle switching component 3 covers the exposed area in its initial position, exposes the exposed area in its pulled position, and adaptively switches back to its initial position after a retraction operation. In the initial position, the toggle switching component 3 covers the exposed area, effectively preventing dust and debris from entering and causing accidental interference to the patch resistor B, ensuring stability during normal transport. When calibration or testing is required, the toggle switching component 3 switches to the pulled position, instantly exposing the exposed area, allowing electrical probes or vision systems to directly contact / observe the patch resistor B, improving calibration efficiency and testing accuracy. Furthermore, after completing the pulled calibration and retraction operation, the toggle switching component 3 adaptively and automatically switches back to its initial position without manual reset or additional mechanical intervention, ensuring the equipment quickly returns to continuous transport, improving production line continuity and capacity.
[0029] Specifically, the toggle switching assembly 3 includes a positioning post 31 disposed on the outer side of the track, a toggle plate 32 movably movable relative to the positioning post 31 along the position switching direction, an operating post 33 attached to the toggle plate 32, and a return spring 34 elastically connected between the operating post 33 and the positioning post 31. The positioning post 31 is disposed on the outer side of the track, and the toggle plate 32 slides against it, limiting the movement trajectory and limit position of the toggle plate 32 between the "initial" and "pull" positions, ensuring that the covering and exposure are freely and accurately aligned during each switching, eliminating errors caused by position drift. Furthermore, the toggle plate 32 can slide movably along the position switching direction, and with the guiding effect of the positioning post 31, achieves a smooth, low-friction switching action, reducing impact and wear between components and improving equipment lifespan. The operating post 33 is directly attached to the toggle plate 32, protruding from the outer side of the track. The operator or robot arm only needs to push / pull the operating post 33 to complete the state switching, without the need for complex tools, improving on-site adjustment efficiency. Furthermore, the reset spring 34 elastically connects the operating column 33 and the positioning column 31, and automatically pulls the toggle plate 32 back to the initial position after the external force is withdrawn. The self-resetting torque is optimized by the spring stiffness, which can overcome friction and avoid excessive impact, ensuring that the equipment can resume continuous conveying without manual reset.
[0030] The actuating plate 32 has a guide groove, and the positioning post 31 is fitted into the guide groove to allow the actuating plate 32 to move freely relative to the positioning post 31 through the guide groove. Thus, the guide groove and the positioning post 31 interlock to form a linear sliding alignment, ensuring that the actuating plate 32 moves smoothly along a predetermined direction during switching, eliminating jitter or offset caused by lateral backlash, and improving the repeatability of the coverage / exposure position. Furthermore, the guide groove constrains the movement of the actuating plate 32, making it less prone to tilting or misalignment when the carrier belt vibrates or external interference occurs.
[0031] The return spring 34 is positioned above the guide groove and is always in a stretched state. Placing the spring above the guide groove and fixing it in a stretched state prevents the spring coil from sagging or shifting due to gravity or vibration, thus avoiding accidental interference between the spring and the carrier belt, the actuating plate 32, or other components, and improving operational reliability. Clearly, the spring being constantly stretched allows it to continuously output a constant restoring force at any position of the actuating plate 32, ensuring that the actuating assembly reliably returns to its initial position after each switch, eliminating the torque attenuation problem caused by spring slack.
[0032] It should be noted that the patch resistors B are arranged in a dotted pattern on the upper side of the strip paper tape A, and are correspondingly hidden within the strip track 1, appearing only in the exposed area. Preferably, the exposed area is a trapezoidal groove, and the top of the actuating plate 32 is provided with a trapezoidal protrusion that is adapted to and engages with the exposed area. Thus, the patch resistors B are arranged in a dotted pattern and are only visible in the trapezoidal groove exposed area, allowing the visual or electrical detection system to focus on a narrow area. The trapezoidal protrusion engages with the groove wall to achieve adaptive centering, eliminating slight lateral and longitudinal offsets and improving the repeatability accuracy of the detection / pull calibration position. The trapezoidal groove and the protrusion edges cooperate to form a mechanical guard, effectively restraining the patch resistors B from lateral sliding or flipping during pulling or detection, ensuring that each resistor element is stably and completely exposed in the calibration area, reducing the risk of misoperation.
[0033] Furthermore, the strip track 1 provides power to the strip paper tape A via an external rewinding mechanism (not shown). It is understood that the connection and driving of the carrier tape via the rewinding mechanism is prior art and will not be elaborated upon here.
[0034] In this embodiment, the pressure plate 2 is adjustablely positioned on the outside of the track to accommodate strips of paper A of different widths. The relative position of the pressure plate 2 and the track can be adjusted via a sliding or positioning mechanism, eliminating the need to replace parts and instantly adapting to various paper strip specifications from narrow to wide, thus meeting the needs of multi-variety, small-batch production.
[0035] The pressing plate 2 is an L-shaped sheet metal part, with the paper pressing operation performed on its short side. When pressing the carrier tape, it is less prone to bending or deformation, ensuring uniform distribution and long-term stability of the pressing force. Furthermore, the short side directly applies pressure to the carrier tape, bringing the point of application close to the track reference plane. This results in a short lever arm and stable force, reducing the twisting or offset of the pressing plate 2 itself, and ensuring reliable pressing and limiting of paper tapes of different widths and materials.
[0036] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
