Description

Technical Field

[0001] This utility model relates to the technical field of switch testing, specifically to a switch testing device. Background Technology

[0002] As a core connection device in a computer network, a switch plays a crucial role in data forwarding, network expansion, and communication control. Its performance, such as port connectivity and signal transmission stability, directly determines the quality of network operation. Therefore, each switch must undergo performance testing before leaving the factory. However, existing testing equipment has several technical shortcomings, specifically as follows: (I) The limitations of traditional manual testing result in extremely low testing efficiency, making it difficult to meet mass production requirements: In traditional manual testing, operators need to complete the entire process of "moving the switch - positioning and placing - plugging and unplugging the test plug - recording the results - sorting out defective products". Taking a common 8-port switch as an example, it takes a skilled worker 3-5 minutes to complete the test of a single unit. Assuming an average effective working time of 8 hours per day, the daily testing volume is only 150-200 units. However, enterprises often place orders for thousands or even tens of thousands of units at a time. Manual testing requires the temporary recruitment of additional employees, which not only increases labor costs (including training and management costs) but also leads to efficiency fluctuations and an increased defect rate due to the unfamiliarity of new employees with the operation.

[0003] (ii) Inability to adjust and poor compatibility with multiple models: The placement of switches at the testing station relies entirely on experience, which easily leads to misalignment, i.e., tilting (at a certain angle with the horizontal). If the misalignment is not adjusted, the test plug will be inserted incorrectly, resulting in poor contact between the test plug and the network port pins, causing testing errors. In severe cases, forced insertion or removal may damage the network port. In addition, different switch models have different specifications, dimensions, and network port positions. Traditional testing requires the creation of a separate positioning fixture for each model. A large number of fixtures need to be stocked, and when changing models, the old fixtures need to be disassembled and the new fixtures installed, resulting in long adjustment times and seriously affecting production efficiency.

[0004] (iii) Difficulty in sorting defective products and low efficiency in subsequent maintenance. After manual testing, the distinction between qualified and defective products relies on the operator's memory or simple paper records. If only some network ports of the switch are faulty (e.g., only 1 out of 8 network ports is damaged), all network ports need to be fully inspected again during subsequent maintenance, wasting a lot of manpower. At the same time, long-term repetitive operation can easily lead to personnel fatigue, and the rate of missed inspection of defective products is high. After unqualified products enter the market, they will cause customer complaints and returns, which will not only increase after-sales costs, but also damage the brand image. Utility Model Content

The adjustment structure includes a baffle and a push plate. The baffle is vertically positioned in front of the transport platform, and the push plate is positioned horizontally behind the transport platform and to the right of the servo motor. The detection structure includes a horizontally arranged detection fixing plate, which is located to the right of the baffle, and a number of detection ends are provided on the lower surface of the detection fixing plate; The defective product marking structure is located to the right of the detection fixing plate, and includes a nozzle with an electronic valve, which is vertically positioned above the transport platform.

[0007] Preferably, the transport block is magnetically connected to several switches along the left and right directions.

[0008] Preferably, the adjustment structure further includes an electronic push rod A and a linear motor.

[0010] Preferably, the defect marking structure further includes a rodless cylinder arranged in the front-rear direction, with a pigment tank fixed to the front of the sliding seat of the rodless cylinder, and the pigment tank being connected to the spray head.

[0011] Preferably, the collection bin is connected to the right end of the transport platform and is inclined, with the front higher than the back.

[0012] This utility model provides a testing device for a switch, which has the following beneficial effects: 1. This device, through fully automated operation, significantly reduces the testing time of a single switch compared to manual operation, easily meeting the needs of large-scale mass production. Furthermore, even without automated loading and unloading devices, only 1-2 operators are required to complete loading and sorting, greatly reducing labor input and workload, and saving enterprise costs.

[0013] 2. The device adjusts the position of the baffle by electronic push rod A and adjusts the stroke of the push plate by linear motor. It can not only straighten the tilted switch, but also adapt to different models of switches within a certain range without changing the fixture, which greatly improves the adaptability of the production line.

[0014] 3. High-contrast, elongated markings are sprayed onto the defective mesh connectors using a spray nozzle. This allows workers to quickly identify the defective products during subsequent sorting, significantly reducing the rate of missed inspections and defective products. Furthermore, since the markings directly correspond to the defective mesh connector locations, no full inspection is required during repairs, reducing rework costs. Attached Figure Description

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0018] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0019] Example 1: Please refer to Figures 1 to 6 A test device for an exchange includes several fixed brackets (1), a transport structure (2), an adjustment structure (3), a detection structure (4), a defect marking structure (5), and a collection bin (6). The transport structure (2) is provided with a transport platform (201) along the left and right direction. The transport platform (201) is fixed on the ground by a bracket (1). The upper surface of the platform (201) is provided with a positioning protrusion (202) along the left and right direction in the middle. The upper surface of the transport platform (201) is also connected to a transport block (203). The lower surface of the transport block (203) is provided with a through groove that matches the positioning protrusion (202). The rear side surface of the transport block (203) is provided with a rack (204) along the left and right direction. The rack (204) is matched with a gear (205). The gear (205) is connected to a servo motor (206). The servo motor (206) is vertically fixed at the rear of the transport platform (201). The adjustment structure (3) includes a baffle (301) and a push plate (302). The baffle (301) is vertically arranged in front of the transport platform (201). The push plate (302) is positioned opposite to the baffle (301) and is horizontally arranged behind the transport platform (201) and to the right of the servo motor (206). The detection structure (4) includes a horizontally arranged detection fixing plate (401), which is located to the right of the baffle (301). The lower surface of the detection fixing plate (401) is provided with a plurality of detection ends (402). The defect marking structure (5) is located to the right of the detection fixing plate (401), and includes a nozzle (501) with an electronic valve, which is vertically positioned above the transport platform (201).

[0020] The transport block (203) is connected to several switches (7) in a magnetic way along the left and right direction. The shape, distribution position and distribution pattern of several network port connectors (701) on the switches match those of the detection terminal (402). The magnetic method facilitates quick loading and unloading of materials and improves the convenience of operation. The magnetic force is preferably such that the switch (7) does not move easily when there is no external force, but can be pushed by the push plate (302).

[0021] The adjustment structure (3) also includes an electronic push rod A (303) and a linear motor (304), both of which are fixed to the ground by a bracket (1). The output rod of the electronic push rod A (303) moves back and forth and its end is vertically connected to a baffle (301). The mover of the linear motor (304) moves back and forth and its upper surface is connected to a push plate (302). The switch (7) is located between the baffle (301) and the push plate (302).

[0022] The detection structure (4) further includes an electronic push rod (403), which is fixed to the ground by a bracket (1). The output rod of the electronic push rod (403) moves up and down and its end is connected to an L-shaped connecting plate (404). The detection fixing plate (401) is fixed on the front of the connecting plate (404).

[0023] The defect marking structure (5) also includes a rodless cylinder (502) arranged in the front and back direction. The rodless cylinder (502) is fixed to the ground by two brackets (1) located on the front and back sides of the transport platform (201) and symmetrically arranged. A pigment tank (503) is fixed on the front of the sliding seat of the rodless cylinder (502). The pigment tank (503) is connected to the nozzle (501). A vertical camera is also provided on one side of the nozzle (501) (not shown in this embodiment).

[0024] The collection bin (6) is connected to the right end of the transport platform (201). It is inclined with the front higher than the back and is fixed to the ground by the bracket (1). The collection bin (6) collects the switches (7) after the test is completed. The inclined design enables the switches (7) to slide down and stack automatically without manual handling.

[0025] The transport platform (201) provides a stable track for the transport block (203), supports the transport block (203), and provides an installation base for the positioning protrusion (202) and the servo motor (206). The transport block (203) serves as the supporting component of the switch (7), driving the switch (7) to move along the transport platform (201). The positioning protrusion (202) cooperates with the through slot to guide and laterally position the transport block (203), preventing the transport block (203) from shifting left or right during movement and ensuring that the switch (7) always moves along the path. The rack (204) and gear (205) form a transmission pair, converting the rotational motion of the servo motor (206) into the linear motion of the transport block (203), realizing the precise movement of the transport block (203).

[0026] The baffle (301) serves as the front reference surface for aligning the switch (7). The push plate (302) applies a steady pushing force from the rear of the switch (7), working in conjunction with the baffle (301) to precisely align the switch (7) while ensuring that the network port connector (701) of the switch (7) is aligned with the detection end (402). The electronic push rod A (303) adjusts the front and rear positions of the baffle (301) and presets the reference position according to the width of the switch (7) to achieve compatibility with different models of switches, providing a basis for the fine adjustment of the push plate (302).

[0027] The detection fixing plate (401) fixes the detection end (402), providing stable support and sufficient mounting surface for the detection end (402), ensuring that the spacing and arrangement of the detection end (402) are completely matched with the network port connector (701) of the switch (7). The detection end (402) is inserted into the network port connector (701) of the switch (7) to detect the network port connectivity, signal transmission rate, and other performance, and outputs the detection results to the control center. The electronic push rod B (403) drives the L-shaped connecting plate (404) and the detection fixing plate (401) to move up and down, controlling the docking and disconnection of the detection end (402) and the network port connector (701).

[0028] The nozzle (501) sprays the pigment stored in the pigment tank (503) to form a clear mark on the defective mesh connector (701). The mark color (such as red or yellow) has a high contrast with the switch, which facilitates rapid identification later. The rodless cylinder (502) moves the pigment tank (503) and the nozzle (501) back and forth to adjust the position of the nozzle (501) and ensure that the pigment is accurately sprayed on the defective mesh connector (701) to form a long strip mark.

[0029] The transport block (203) carrying several switches (7) is fed in from the left side of the transport platform (201). The bottom groove of the transport block (203) engages with the positioning protrusion (202) for positioning and sliding guidance. The servo motor (206) is started, and the gear (205) rotates to mesh with the rack (204), causing the transport block (203) to move to the right. When the switches (7) on it move between the baffle (301) and the push plate (302), because the switches (7) were initially placed on the transport block (203) at an angle (with a certain angle to the horizontal direction), in order to ensure the accurate insertion of the detection end (402), the linear motor (304) is started, causing the push plate (302) to move to the right. Push the back side of the switch (7) forward. Because of the baffle (301), it can be straightened. The distance between the two is adjustable so that the network port connector (701) of the switch (7) after being straightened is located directly below the detection end (402). The specific adjustment is generally based on calculation (the specific calculation method is not shown). Generally, for the same product, after determining the distance between the two based on its width and the position of the network port connector (701), the position of the baffle (301) will not move. When changing to another product, the position of the baffle (301) is adjusted by the electronic push rod A (303). The correctly positioned switch (7) continues to move to the right, coming to a position directly below the detection head (402). The electronic push rod (403) is activated, causing the detection head (402) to descend and insert into the network port connector (701), starting to detect network port connectivity, signal transmission rate, etc. After the detection is completed, it continues to move to the right. If a network port connector (701) is found to be faulty, i.e. defective, when the defective network port connector (701) passes directly below the nozzle (501) it is captured by the camera. At this time, the electronic valve on the nozzle (501) opens and the rodless cylinder... (502) Start the rapid forward and backward movement. The pigment in the pigment tank (503) is sprayed from the nozzle (501) onto the upper surface of the defective mesh connector (701) to form a long strip with a clear color difference as a defective product mark. The switch (7) continues to move to the right and arrives at the end of the transport platform (201). After the through groove of the transport block (203) disengages from the positioning protrusion (202), it slides down and accumulates along the inclined surface of the collection bin (6). It is then picked up by the workers. The workers can easily spot the defective product mark and select it for inspection and repair. By continuously feeding the transport block (203), the inspection is carried out in a cycle.

[0030] Working process: According to the specific relevant parameters of the switch (7) to be tested, the operator sets the relevant parameters through the control center (not shown in this embodiment): the stroke of the electronic push rod A (303) adjusts the position of the baffle (301) and fixes it, the stroke of the linear motor (304) sets the distance of the push plate (302) to be aligned, the stroke of the electronic push rod B (403) determines the insertion depth of the detection end (402), the speed of the servo motor (206) is set in coordination, and the spray width and paint output of the nozzle (501) are set in coordination. Several switches (7) are fixed to the upper surface of the transport block (203) by magnetic attraction, the bottom through groove of the transport block (203) is aligned with the positioning protrusion (202) of the transport platform (201), and placed at the starting position on the left side of the transport platform (201). The gear (205) and the rack (204) are matched and meshed.

[0031] The servo motor (206) starts and drives the gear (205) to rotate. The gear (205) meshes with the rack (204) behind the transport block (203), driving the transport block (203) to move smoothly to the right along the transport platform (201).

[0032] When the transport block (203) carrying the switch (7) moves between the baffle (301) and the push plate (302), the electronic push rod A (303) is activated. The output rod of the electronic push rod A (303) extends backward, driving the baffle (301) to move to the preset position and then stop. The linear motor (304) is activated. The mover of the linear motor (304) drives the push plate (302) to move forward. The push plate (302) contacts the rear side of the switch (7) and applies a pushing force, which, together with the baffle (301), straightens the switch (7). At this time, the network port connector (701) and the detection end (402) are also aligned.

[0033] When the transport block (203) moves directly below the detection fixing plate (401), the electronic push rod B (403) is activated. The output rod of the electronic push rod B (403) extends downward, causing the L-shaped connecting plate (404) and the detection fixing plate (401) to descend rapidly. The detection end (402) on the lower surface of the detection fixing plate (401) is inserted into the network port connector (701) of the switch (7). The detection end (402) is connected to the control center and begins to detect the network port connectivity, signal transmission rate, etc. The detection data is uploaded to the control center in real time. If all network ports are qualified, the system records "qualified"; if a certain network port is faulty, the system marks the location of the network port.

[0034] After the test is completed, the test head (402) rises and resets, and the switch (7) continues to move to the right to the defective marking structure (5) area; when the camera captures the defective network port connector (701) coming to the position below the nozzle (501), the rodless cylinder (502) starts to drive the nozzle (501) to move back and forth quickly, and at the same time the electronic valve on the nozzle (501) opens, and the nozzle (501) sprays out pigment to form a long strip mark; after the marking is completed, the nozzle (501) resets and the electronic valve closes.

[0035] The switch (7) moves with the transport block (203) to the right end of the transport platform (201). The transport block (203) separates from the positioning protrusion (202). Under the action of gravity, the switch (7) slides down the inclined surface of the collection bin (6) to the bottom of the bin. The operator takes the switch (7) from the collection bin (6) and sorts the defective products (because the defective product markings can be identified at a glance) and qualified products. During this period, new transport blocks (203) and switches (7) are continuously added to the starting position on the left to realize the cyclical operation of the test process.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
