Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to an electronic component feeding device. Background Technology

[0002] With the development of technology, circuit board processing increasingly uses automated equipment, such as robotic arms for insertion, which is not only fast and efficient but also saves labor.

[0003] Current electronic component feeding devices generally consist of a single vibrating feeder, requiring multiple stations for different components to be inserted or placed during through-hole or surface mount processing. This results in inefficiency and increases equipment costs and energy consumption due to the multiple sets of equipment. Therefore, this invention proposes an electronic component feeding device to at least partially solve the problems existing in the prior art. Utility Model Content

[0004] In view of the above problems, the present invention is proposed to provide an electronic component feeding device that overcomes or at least partially solves the above problems.

[0005] To address the aforementioned problems, this utility model discloses an electronic component feeding device, comprising:

[0006] At least two vibrating feeders are connected to a feed chute; the feed chute extends to the lower end of the robotic arm of the processing equipment.

[0007] The lower end of the feeding trough is connected to a linear vibrator, and the lower end of the linear vibrator is provided with a support platform.

[0008] Optionally, a workbench may also be included;

[0009] The vibrating feeder and the support platform are mounted on the workbench.

[0010] Optionally, the vibrating feeder is located on the same side or both sides of the feed trough.

[0011] Optionally, four vibrating feeders are provided.

[0012] Optionally, an optical fiber plate is also provided on one side of the end of the feeding trough;

[0013] The fiber optic board is provided with mounting holes for mounting fiber optic sensors.

[0015] The support leg is connected to the lower end of the workbench via a screw.

[0016] This utility model has the following advantages:

A vertical vibrator is connected to the lower end of the feed trough, and a support platform is provided at the lower end of the vertical vibrator. By simultaneously supplying different electronic components to the processing equipment through two or more vibrating feeders, the robotic arm can pick up different electronic components at the end of the feed troughs and assemble them onto a circuit board. This not only reduces station changeover time but also improves the continuous picking efficiency of the robotic arm. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figures 1 to 7 An embodiment of the electronic component feeding device of this utility model may specifically include: at least two vibrating feeders 101, with a feeding trough 102 connected to the vibrating feeder 101; the feeding trough 102 extends to the lower end of the robot arm of the processing equipment; the lower end of the feeding trough 102 is connected to a linear vibrator 104, and the lower end of the linear vibrator 104 is provided with a support platform 103.

[0027] By simultaneously supplying different electronic components to the processing equipment using two or more vibrating feeders, a robotic arm can pick up different electronic components at the end of the feed trough 102 and assemble them onto the circuit board. This not only reduces station changeover time and improves the robotic arm's continuous picking efficiency (theoretically increasing efficiency by 40%-60%), but also shortens the material feeding path and reduces the risk of electrostatic interference from components. For example, multiple sets of vibrating feeders 101 can respectively transport different components such as capacitors and inductors, and the feed troughs 102 converge at the end of the robotic arm's gripping area.

[0028] In one embodiment of this application, a workbench 201 is further included; the vibrating feeder 101 and the support platform 103 are mounted on the workbench 201. Through the integrated design of the workbench 201, the components and equipment required for the vibrating feeder 101 are integrated at the lower end of the workbench 201. Furthermore, by setting a corresponding vibration damping device between the vibrating feeder 101 and the workbench 201, the stability of the equipment is enhanced, and resonance interference between the vibrating feeders is reduced, making it suitable for high-speed continuous feeding scenarios. Preferably, the workbench 201 is made of aluminum alloy and incorporates built-in vibration damping and corresponding counterweights.

[0029] The vibrating feeder 101 is located on the same side or both sides of the feed trough 102.

[0030] Furthermore, such as Figure 5 As shown, four vibratory trays 101 can be preferably provided to accommodate various package specifications and meet the needs of mixed SMT and THT production lines. For example, two sets of trays can be used to supply surface mount resistors and capacitors respectively, while the other two sets can supply irregularly shaped through-hole components.

[0031] In one embodiment of this application, an optical fiber plate 106 is further provided on one side of the end of the feeding trough 102; the optical fiber plate 106 is provided with mounting holes 107 for mounting optical fiber sensors. By installing optical fiber sensors through the above structure, status monitoring can be achieved, real-time feedback on feeding anomalies can be provided, and vibration frequency can be controlled in conjunction with the system to reduce downtime due to material shortages; for example, a reflective optical fiber sensor can be installed on the side wall to detect the accumulation status of elements or to detect whether materials have reached that position.

[0032] The workbench 201 is equipped with support legs and casters at its lower end; the support legs are connected to the lower end of the workbench 201 via screws. This enables rapid positioning and fine-tuning of the equipment, adapting to the dynamic layout requirements of multiple workstations in a factory. The casters can have built-in electromagnetic brakes, and the support legs are equipped with graduated adjustment rings.

[0033] As an example, the aforementioned vibratory feeder 101 synchronizes vibration frequency and feeding rhythm via a PLC controller; it dynamically adjusts the amplitude parameters of different feeders based on component volume to ensure consistent component spacing within the feeding trough; it avoids waiting periods for the robotic arm due to differences in feeding speed, improving production line cycle consistency. A rotatable connector can be provided at the end of the feeding trough 102, supporting 0-30° tilt adjustment to match different gripping height requirements of the robotic arm, reducing the probability of component slippage, optimizing component slippage trajectories, and adapting to high-density PCB processing scenarios. A semiconductor cooling pad and a constant temperature monitoring module can also be integrated into the worktable 201 to ensure the vibratory feeder temperature remains ≤35℃ in high-temperature environments, preventing oxidation of heat-sensitive components, thereby further expanding the equipment's applicable environment range and meeting automotive-grade electronic component processing requirements. Replaceable guide strips are embedded in the inner wall of the feeding trough 102, with a diamond-like carbon coating on the surface. The design of corrugated guide grooves for non-standard components such as LED beads can reduce the surface scratch rate of components (tested to reduce scratch rate by 78%), improving the yield of precision machining. The aforementioned fiber optic board 106 can also be equipped with fiber optic sensors and infrared photoelectric sensors, allowing for mutual backup through dual monitoring modes. For example, by using a threshold comparison algorithm to identify false trigger signals, the failure rate of critical workstations can be reduced to 0.02 times / thousand hours, meeting the reliability requirements of unmanned factories. Current sensors are installed in the power supply circuits of each vibrating tray 101, and the data is visualized through an HMI interface.

[0034] In this application, by using multi-vibration source collaborative feeding, intelligent control and modular design, the speed bottleneck of traditional single material tray system is broken through. The efficiency of a single device can reach more than 2.2 times that of the original device, while reducing the equipment purchase cost by 35%-50%.

[0035] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or terminal device that includes said element.
