[0026] This embodiment provides an electrostatic discharge device, such as... Figures 1-11 As shown, the electrostatic discharge device includes a feeding component 1 and a discharge component 2. The feeding component 1 has an inclined surface, which allows the electronic component 3 to slide along the inclined surface to at least one discharge position by gravity. The discharge component 2 is disposed at the discharge position and is used to perform electrostatic discharge on the electronic component 3.

[0027] The inclined surface of the feeding assembly 1 is designed as a ramp structure, with its end directly guiding to the discharge position, allowing the electronic component 3 to slide naturally and accurately reach the discharge position under gravity. The discharge assembly 2 is fixedly installed at the discharge position, tightly connected to the end of the feeding assembly 1, to ensure that the electronic component 3 can be processed immediately after sliding into place. More specifically, the inclination of the inclined surface is designed to optimize the sliding process, and the discharge position is located at the end of the sliding path. The feeding assembly 1 and the discharge assembly 2 form a continuous material flow path through physical alignment, thereby ensuring the smooth transfer and precise positioning of the electronic component 3. The function of the feeding assembly 1 is to automatically transport the electronic component 3 to the discharge position using gravity through the inclined surface, reducing manual intervention and handling steps. The function of the discharge assembly 2 is to perform electrostatic discharge on the electronic component 3 at the discharge position, ensuring sufficient pin contact and complete discharge. The discharge position serves as a key point connecting the feeding and discharging processes, providing a stable contact area to ensure reliable execution of the discharge action. More specifically, the automated design of the feeding assembly 1 reduces the labor intensity of the operators, while the automated operation of the discharge assembly 2 improves the consistency and efficiency of the discharge, and the discharge position ensures that the electronic components 3 stay at the correct point to complete a high-quality discharge.

[0028] Electronic component 3 is first placed on the feeding assembly 1 and slides along the inclined surface under gravity, moving directly to the discharge position. Once electronic component 3 reaches the discharge position, the discharge assembly 2 is activated to electrostatically discharge the pins of electronic component 3. Furthermore, this coordination achieves a fully automated process. The inclined surface of the feeding assembly 1 guides the electronic component 3 to slide down in an orderly manner, avoiding chaos, while the discharge position serves as a transfer point to ensure stable stopping. The discharge assembly 2 responds automatically to the arrival of electronic component 3, thus forming a seamless connection and ensuring that each electronic component 3 can complete the discharge without manual operation.

[0029] In this embodiment, the inclined surface of the feeding assembly 1 automatically transports the electronic components 3 using gravity, eliminating the problems of irregular operation and high labor intensity caused by manual handling, and ensuring that each electronic component 3 can vertically contact the discharge position; the discharge assembly 2 automatically discharges at the discharge position, avoiding failure of motherboard components due to incomplete or missed discharge by manual handling. More specifically, the automated process improves discharge efficiency, reduces operation time, and ensures discharge quality through stable discharge points, thereby solving the problems of quality defects and low efficiency.

[0030] In a specific embodiment, such as Figure 2 and Figure 3 As shown, the feeding assembly 1 includes a feeding plate 11 and a vibration unit 12. The feeding plate 11 forms the inclined surface, and the vibration unit 12 is mounted on the feeding plate 11 to facilitate the sliding of the electronic component 3. The vibration unit 12 is a vibrator.

[0031] The feed plate 11 includes a flat plate area and a downwardly extending inclined plate area, with a reinforcing plate 112 at the bottom between the flat plate area and the inclined plate area; this inclined plate area forms the aforementioned inclined surface; the vibration unit 12 is directly installed below the flat plate area of ​​the feed plate 11, and its position design allows the generated vibration to be effectively transmitted to its flat plate area. The function of the feed plate 11 is to provide a complete feeding path. Its flat plate area is used to hold a large number of electronic components 3 at once, while the inclined plate area uses gravity to guide the electronic components 3 to slide downward automatically and orderly, realizing the initial conveying and orientation of materials; the function of the vibration unit 12 is to generate continuous and slight mechanical vibration, which overcomes the static friction between the electronic components 3 and their adhesion to the surface of the feed plate 11, assisting them to disperse from the flat plate area to the inclined plate area and initiate sliding. More specifically, the structure of the feed plate 11 plans the flow direction of the material, while the vibration unit 12 provides initial power and continuous protection for this flow, preventing material blockage in the transition area.

[0032] After the electronic component 3 is placed on the flat area of ​​the feeding plate 11, the vibration unit 12 starts to work. The vibration generated causes the electronic component 3 to be shaken apart and gradually gather towards the inclined plate area, and then slide down the inclined surface by gravity. This coordination realizes the connection between batch storage and automatic, continuous, and single-piece conveying of the electronic component 3. More specifically, it effectively solves the trouble of frequent manual feeding and ensures that the electronic component 3 can enter the subsequent process at a stable and uniform rhythm, which greatly improves the automation level of feeding and the operating efficiency of the entire device.

[0033] In a specific embodiment, such as Figure 2 and Figure 5As shown, the feeding assembly 1 also includes a first sensing element 13, which is disposed on the side of the feeding plate 11 and is used to sense whether the electronic component 3 enters the inclined surface, thereby controlling the working state of the vibration unit 12.

[0034] The first sensor 13 is installed on the side of the inclined surface of the feeding plate 11. Its function is to accurately monitor whether electronic components 3 have arrived and entered the inclined surface. More specifically, when the first sensor 13 detects that an electronic component 3 has successfully entered the inclined surface, it immediately sends a signal to control the vibration unit 12 to temporarily stop working. This is to prevent the electronic components 3 accumulated on the flat area of ​​the feeding plate 11 from excessively flooding into the inclined surface under continuous vibration. The core effect of this design is to achieve intelligent regulation of the feeding flow rate, effectively avoiding congestion and jamming of electronic components 3 in the narrow inclined surface channel. Furthermore, it ensures that the material is transported downstream in a small and orderly manner, creating stable and uniform working conditions for subsequent material distribution and discharge processes, thereby improving the reliability and continuity of the entire device operation from the source.

[0035] In a specific embodiment, such as Figure 2 As shown, the feeding assembly 1 also includes a dispensing unit 14, which is located downstream of the feeding plate 11 and is used to intermittently deliver the electronic components 3 to the discharge position.

[0036] The material distribution unit 14 is located at the downstream outlet of the inclined surface of the feeding plate 11. Its function is to receive the electronic components 3 that continuously slide down from the inclined surface and convert them into intermittent, individual deliveries. More specifically, the material distribution unit 14 uses a specific internal mechanical structure, such as a turntable with slots, to periodically stop and release the electronic components 3, thereby achieving rhythmic control of the material flow and ensuring that the electronic components 3 are transported one by one to the designated discharge position in a rhythmic manner. The key effect of this design is to transform the previously continuous material flow into a step-by-step, controllable conveying process, providing the necessary operating interval time for the downstream discharge process. Furthermore, it effectively prevents the accumulation and collision of electronic components 3 at the discharge position, ensuring that each electronic component 3 can be accurately positioned and receive a full and complete electrostatic discharge, thus fundamentally solving the problems of operational chaos, incomplete discharge, and decreased equipment reliability that may be caused by continuous discharge.

[0037] In a specific embodiment, such as Figure 2 and Figure 3As shown, the material distribution unit 14 includes a rotating disk 141 and a drive motor 142. The rotating disk 141 is provided with a slot 1411 for accommodating the electronic components 3. The drive motor 142 is configured to drive the rotating disk 141 to rotate, so as to transport the electronic components 3 in a step-by-step manner.

[0038] The output shaft of the drive motor 142 is directly connected to the central shaft of the rotating disk 141, thereby transmitting power to the rotating disk 141. The rotating disk 141 is positioned below the outlet of the upstream feed plate 11 to receive the sliding electronic components 3, while the drive motor 142 is typically installed to the side or below the rotating disk 141 to save space. The rotating disk 141 uses slots 1411 of a specific shape on its circumferential edge to receive and accommodate the electronic components 3 one by one, and its rotational motion will drive the electronic components 3 out of the feed channel. The drive motor 142 provides precise and controllable rotational power for the entire material distribution process. It starts and stops according to set instructions, driving the rotating disk 141 to perform intermittent rotational motion.

[0039] After receiving a signal from the control system, the drive motor 142 drives the rotating disk 141 to rotate by a fixed angle, so that an empty slot 1411 rotates accurately below the outlet of the feeding plate 11 to receive an electronic component 3. Then, the drive motor 142 operates again, and the rotating disk 141 rotates by another angle, moving the slot 1411 that carries the electronic component 3 to the discharge position. At the same time, the next empty slot 1411 rotates to the receiving position, and so on. The core effect of this close coordination is to realize the transformation of the continuous electronic components 3 into a step-by-step, intermittent conveying with precise pauses. More specifically, it provides the necessary stable dwell time for each electronic component 3 to perform electrostatic discharge at the discharge position, thereby ensuring the thoroughness and reliability of the discharge operation. At the same time, this mechanical material distribution method has a simple structure and controllable rhythm, which greatly improves the working efficiency and stability of the entire device.

[0040] In a specific embodiment, such as Figure 2 As shown, the material dispensing unit 14 further includes a sensing rod 143 and a second sensing element 144. The sensing rod 143 is disposed on the rotating disk 141 and rotates with the rotating disk 141. The second sensing element 144 is fixed on the outer edge 1412 of the rotating disk 141 and is used to sense the sensing rod 143 and thereby control the working state of the discharge assembly 2. There are multiple sensing rods 143 and slots 1411, and they correspond one-to-one. There is a corresponding sensing rod 143 between each pair of adjacent slots 1411.

[0041] The sensing rod 143 is directly mounted on the rotating disk 141, and its position is associated with the slot 1411 on the disk. The second sensing element 144 is stationary and is fixedly mounted on a non-rotating flange 1412 on the outer side of the rotating disk 141. The sensing rod 143 periodically passes through the sensing area of ​​the second sensing element 144 as the rotating disk 141 rotates, and there is a non-contact relative motion relationship between the two. The main function of the sensing rod 143 is to serve as a detected physical marker, and its trajectory directly reflects the real-time angular position of the rotating disk 141. The function of the second sensing element 144 is to act as a detector, used to non-contactly sense whether the sensing rod 143 has reached the predetermined position, and to convert this position signal into an electrical signal output.

[0042] When the drive motor 142 rotates the rotating disk 141, the sensing rod 143 also rotates synchronously. Whenever a slot 1411 carrying an electronic component 3 rotates to the precise discharge position, the corresponding sensing rod 143 also enters the sensing range of the second sensing element 144. At this moment, the second sensing element 144 immediately detects the sensing rod 143 and generates a trigger signal, which is instantly transmitted to the discharge assembly 2, instructing it to begin the discharge operation. The core effect of this precise coordination is the strict synchronization and connection between the material dispensing action and the discharge action. It ensures that the discharge operation is only triggered when the electronic component 3 is transported to an absolutely accurate position, thus fundamentally eliminating the problem of incomplete discharge or misoperation caused by positioning deviation. Furthermore, this one-to-one correspondence design allows each electronic component 3 to obtain a consistent and complete processing cycle, greatly improving the accuracy and reliability of the entire device.

[0043] In a specific embodiment, such as Figure 2 and Figure 5 As shown, the discharge assembly 2 includes a first discharge unit 21, which is configured to be activated when the second sensing element 144 senses the sensing rod 143, and to perform a first downward discharge on the electronic component 3 located at the discharge position.

[0044] The first discharge unit 21 receives a control signal from the dispensing unit 14. More specifically, it is only triggered when the second sensor 144 successfully senses that the corresponding sensor rod 143 has reached the predetermined position. This triggers the unit to perform a specific discharge action on the electronic component 3, which has been precisely positioned by the rotating disk 141. This action is a downward discharge, where the discharge component actively moves downward to contact the pins of the electronic component 3. The key effect of this design is the realization of a high degree of automation and extreme precision in the discharge operation. It completely replaces the unstable operation that previously required manual handling and alignment of the discharge board. Through the linkage of mechanical and electrical systems, it ensures that each discharge is performed when the electronic component 3 is in the most ideal position, and the downward method ensures sufficient and reliable contact between the pins and the discharge board. Furthermore, this signal-triggered automatic discharge mechanism fundamentally eliminates problems such as missed discharge, insufficient discharge time, or poor contact caused by human negligence or fatigue, thereby significantly improving the quality and consistency of electrostatic discharge and laying the foundation for ensuring the quality of subsequent motherboard assembly.

[0045] In a specific embodiment, such as Figure 2 As shown, the first discharge unit 21 includes a linear driver 211 and a movable discharge plate 212. The linear driver 211 is signal-connected to the second sensor 144 and configured to drive the movable discharge plate 212 to move to contact and press the pins of the electronic component 3.

[0046] The output of the linear actuator 211 is mechanically connected to the movable discharge plate 212, enabling it to push and pull the movable discharge plate 212 to perform vertical linear motion. The linear actuator 211 is typically fixed to the overall support of the device, while the movable discharge plate 212 is suspended above the rotating disk 141. Its position is precisely adjusted to ensure that when the slot 1411 of the rotating disk 141 stops rotating, the movable discharge plate 212 is directly aligned with the pin of the electronic component 3 at the discharge position. The linear actuator 211 acts as a power actuator, immediately generating a precise linear reciprocating motion upon receiving the electrical signal from the second sensor 144. The movable discharge plate 212 acts as the direct actuator for discharge, with conductive material at its lower end. Driven by the linear actuator 211, it moves downwards and eventually makes physical contact with the pin of the electronic component 3 to complete the electrostatic discharge.

[0047] When the second sensor 144 detects the sensor rod 143, indicating that the electronic component 3 is in place, a signal is immediately sent to the linear driver 211. The linear driver 211 then activates, pushing the movable discharge plate 212 downwards. The movable discharge plate 212 smoothly presses against the pin of the electronic component 3, maintaining a certain pressure and contact time, thereby ensuring that static electricity is completely discharged. After the discharge is completed, the linear driver 211 pulls the movable discharge plate 212 back to its original position, preparing for the next working cycle. This method simulates the action of a human hand pressing the component against the discharge plate, but it is more precise, stable, and powerful than manual operation, thoroughly guaranteeing the contact quality and contact time between the pin and the discharge plate. This fundamentally eliminates the problem of incomplete discharge caused by poor contact or insufficient contact time, thereby greatly improving the success rate and reliability of the first discharge.

[0048] In a specific embodiment, such as Figure 2 As shown, the discharge assembly 2 further includes a second discharge unit 22, which includes a discharge channel 221 and a first fixed discharge plate 222. The discharge channel 221 is connected to the discharge end of the distribution unit 14, so that the electronic component 3 that has completed the first downward discharge slides down and contacts the first fixed discharge plate 222 to complete the second contact discharge.

[0049] While the initial downward discharge is active and reliable, the second discharge serves as an essential backup and supplement, ensuring that any static electricity that might not have been fully released during the first discharge due to extremely rare factors is completely eliminated. This significantly improves the reliability of the entire discharge process and the safety of product quality. More specifically, this design follows the principle of redundancy safety, minimizing the risk of damage to motherboard components due to a single discharge failure.

[0050] The inlet end of the discharge channel 221 is directly connected to the discharge end of the dispensing unit 14, and its outlet end extends above the first fixed discharge plate 222. The discharge channel 221 itself is designed as a ramp structure, and the first fixed discharge plate 222 is fixedly installed at the bottom end of the ramp. The function of the discharge channel 221 is to provide a controlled exit path for the electronic component 3 that has completed its first discharge. It uses gravity to guide the electronic component 3 to slide naturally towards the collection area. The function of the first fixed discharge plate 222 is to act as a discharge terminal that is always in a standby state. When the electronic component 3 slides down the discharge channel 221 and passes over its surface, the pins of the component will make instantaneous contact with the first fixed discharge plate 222.

[0051] After the electronic component 3 is released from the rotating disk 141, it enters the discharge channel 221 under its own gravity and begins to accelerate and slide. At the end of its sliding trajectory, its pins will inevitably make a scraping or touching contact with the fixedly mounted first fixed discharge plate 222. Although this contact is brief, it is enough to form an effective electrostatic discharge path. The key effect of this combination is to achieve efficient, zero-energy secondary discharge, further consolidating the discharge effect.

[0052] In a specific embodiment, such as Figure 10 and Figure 11 As shown, the feeding assembly 1 is a tubular hopper 101, which has an inclined surface so that the electronic components 3 slide down to the discharge position under the action of gravity; the tubular hopper 101 contains a plurality of the electronic components 3.

[0053] This embodiment describes an alternative implementation of the feeding component 1, which differs significantly from the above-described implementation in both overall concept and specific structure.

[0054] The feeding assembly 1 is a tubular hopper 101. This hopper is installed at an angle, or can be installed at an angle between two opposing plate-like structures, thus its inner wall naturally forms the inclined surface. Multiple electronic components 3 are pre-placed side-by-side in the internal pipes of the tubular hopper 101. When the first electronic component 3 is removed, subsequent electronic components 3 slide down the inclined inner wall of the pipe under their own weight, automatically replenishing the discharge position at the end of the pipe. This design significantly simplifies the structural complexity and manufacturing cost of the device. It completely eliminates the need for a vibration unit, a dispensing unit, and a series of sensing and control elements, achieving automatic material conveying solely through gravitational potential energy and pipe constraints. More specifically, while this solution may not be as efficient as highly automated solutions, its structure is extremely simple and reliable, with virtually no risk of mechanical failure. It is very suitable for applications where production rhythm requirements are not extremely stringent, while also achieving the goal of reducing manual handling and lowering labor intensity.

[0055] In a specific embodiment, the discharge assembly 2 includes a second fixed discharge plate 201 disposed at the discharge position. When the electronic component 3 slides onto the second fixed discharge plate 201, it completes a single discharge through pin contact.

[0056] The core component of discharge assembly 2 is a single fixed discharge plate 201, which is fixedly installed at the discharge position below the outlet of the tubular hopper 101. Its operation is passive; when the electronic component 3 slides out of the inclined tubular hopper 101, it naturally falls onto the surface of the fixed discharge plate 201 due to its downward inertia. At this instant, the pins of the electronic component 3 make physical contact with the fixed discharge plate 201, forming a conductive path and completing one electrostatic discharge. The outstanding effect of this design is the maximum simplification of the entire discharge device structure and a significant reduction in cost. It completely eliminates the complex first discharge mechanism containing moving parts such as linear actuators, and also eliminates the need for a second discharge process, achieving basic functionality solely through a fixed discharge plate. More specifically, although this scheme simplifies the two-stage discharge guarantee to a single discharge, its method of contact discharge using the kinetic energy of the naturally falling material is very direct and reliable, with almost no risk of mechanical failure, thus improving the durability and stability of the device.

[0057] In a specific embodiment, the electrostatic discharge device further includes a recovery component 4, which is disposed on the side of the tubular silo 101 for recovering the empty tubular silo 101.

[0058] The recycling component 4 is located on the side of the tubular silo 101. Its structure can be a simple collection basket 41 or an inclined slide. Of course, it also includes a cylinder 42. The cylinder 42 can drive the tubular silo 101 to move into the collection basket 41. Its function is to receive and collect the empty tubular silo 101 itself after all the electronic components 3 in the tubular silo 101 have been used up, so as to realize the automatic or semi-automatic collection of empty silos.

[0059] In a specific embodiment, the electrostatic discharge device further includes a support frame 5, on which the feeding component 1 and the discharge component 2 are mounted.

[0060] The support frame 5 forms the main skeleton of the device. The feeding assembly 1 and the discharge assembly 2, as core functional modules, are directly installed and fixed on the support frame 5, thus integrating into a complete equipment unit. The support frame 5 integrates all moving and precision parts on a robust base, effectively reducing the impact of vibration or external interference on the feeding and discharge accuracy. Furthermore, the presence of the support frame 5 makes the entire device an independent and movable whole. This design allows it to flexibly adapt to process or line adjustments made due to product changes on the production line, greatly enhancing the applicability and mobility of the equipment and facilitating the optimization of production layout.

[0061] In a specific embodiment, the feed plate 11 is provided with guard plates 111 on both sides for constraining the sliding path of the electronic component 3.

[0062] The guard plates 111 are vertically fixed to the left and right edges of the inclined surface of the feed plate 11, forming a guide channel together with the working surface of the feed plate 11. This channel allows the electronic components 3 to pass smoothly while effectively restricting their lateral movement. The primary function of this embodiment is to ensure that the movement trajectory of the electronic components 3 during gravity descent is predictable and controllable, effectively preventing material scrap or production interruption caused by components accidentally falling from the edge of the feed plate 11. The restraining effect of the guard plates 111 ensures that the electronic components 3 can be accurately conveyed to the downstream dispensing unit 14 or directly to the discharge position in the correct posture, avoiding blockage problems caused by material tilting or jamming.

[0063] In a specific embodiment, the material dispensing unit 14 further includes a speed regulator 145 for adjusting the rotational speed of the drive motor 142. The speed regulator 145 is electrically connected to the drive motor 142, and the operator can use it to set or change the rotational speed of the drive motor 142 in real time.

[0064] By adjusting the speed controller 145, the interval time required for the rotary disk 141 to rotate one station can be precisely controlled, thereby directly determining the duration of the electronic component 3's stay at the discharge position. More specifically, when production efficiency needs to be improved, the speed can be appropriately increased to shorten the cycle; while when the discharge time needs to be extended to ensure the complete discharge of certain special components, the speed can be decreased. This adjustability allows a single device to flexibly cope with different production process requirements, ensuring that the discharge quality is always under control and avoiding device mismatch due to changes in production line speed.

[0065] In a specific embodiment, the inlet and outlet of the discharge channel 221 are provided with limiting structures 2211 to guide the electronic components 3 to slide toward the first fixed discharge plate 222.

[0066] The limiting structure 2211 is installed at the entrance and exit of the discharge channel 221. When the electronic component 3 is released from the dispensing unit 14 and is about to enter the discharge channel 221, the limiting structure 2211 will first contact the electronic component 3. This embodiment ensures that the electronic component 3 can smoothly and accurately enter the discharge channel 221 and slide towards the predetermined discharge area. More specifically, the limiting structure 2211 can correct the slight positional deviation or tilt that may occur when the electronic component 3 leaves the dispensing unit 14, and guide the component through its physical constraint so that it enters the ramp channel in the required posture. In this way, the electronic component 3 can remain stable during the sliding process, and finally its pins can reliably make effective contact with the first fixed discharge plate 222 waiting below, thereby successfully completing the second contact discharge. Furthermore, this simple mechanical structure fundamentally prevents the electronic component 3 from getting stuck, flipping, or sliding off the track at the discharge entrance, ensuring the continuity and reliability of the secondary discharge process and improving the stability of the entire device operation.

[0067] The working process of the electrostatic discharge device provided in this embodiment is as follows: The entire electrostatic discharge process begins with placing the electronic components 3 onto the flat area of ​​the feeding plate 11. Subsequently, the vibration unit 12 is activated, generating high-frequency, low-amplitude vibrations that are transmitted to the feeding plate 11, causing the stacked electronic components 3 to be shaken apart and moved orderly towards the inclined plate area. A first sensor 13, installed on the side, continuously monitors the material condition at the entrance of the inclined plate area. When it senses that an electronic component 3 is beginning to enter the inclined surface, it sends a signal to intermittently pause the vibration unit 12 to prevent material congestion on the slope. Under the influence of gravity, the electronic components 3 slide down the inclined surface of the feeding plate 11 in a single row, eventually reaching the dispensing unit 14 at its end.

[0068] The rotating disk 141 of the feeding unit 14 rotates in a step-by-step manner under the drive of the drive motor 142. The speed of the drive motor 142 can be adjusted by the speed regulator 145 to match the production cycle. The slots 1411 on the circumference of the rotating disk 141 rotate sequentially to below the outlet of the feeding plate 11, accurately catching each sliding electronic component 3. As the rotating disk 141 rotates, the sensing rod 143 fixed on it also rotates synchronously. When the slot 1411 carrying the electronic component 3 rotates to the precise discharge position, the corresponding sensing rod 143 just enters the sensing area of ​​the second sensing element 144 fixed on the stop 1412. The second sensing element 144 immediately sends a signal to start the first discharge unit 21.

[0069] Upon receiving a signal, the linear actuator 211 of the first discharge unit 21 quickly actuates, pushing the movable discharge plate 212 downwards. The movable discharge plate 212 smoothly presses against the pins of the electronic component 3 located at the discharge position, performing a first downward discharge lasting approximately two seconds. After the discharge is complete, the linear actuator 211 pulls the movable discharge plate 212 upwards to reset. Almost simultaneously, the drive motor 142 drives the rotary disk 141 to rotate to the next station, delivering the electronic component 3, which has completed its first discharge, to the entrance of the discharge channel 221. The limiting structure 2211 at the entrance of the discharge channel 221 guides the electronic component 3 into the ramp channel in the correct posture. The electronic component 3 accelerates down due to gravity, and at the end of its sliding trajectory, its pins contact the first fixed discharge plate 222 fixedly installed at the bottom of the channel, completing the second contact discharge. Finally, the electronic component 3, completely discharged from static electricity, slides out of the discharge channel 221 and is taken away by the operator for subsequent insertion, thus completing a complete work cycle. The entire process is supported by the support frame 5, and the guard plate 111 ensures the stability of the sliding path, realizing fully automatic, efficient and reliable electrostatic discharge.

[0070] In summary, it is readily understood by those skilled in the art that, without conflict, the aforementioned advantageous technical features can be freely combined and superimposed.
