[0020] Figure 1 The layout of the test pipeline in an embodiment is schematically shown in the perspective view.

[0021] Figure 2 A second test station of the test pipeline in an embodiment is shown. DETAILED DESCRIPTION

[0022] The test production line of this utility model will be further explained and described below with reference to the accompanying drawings and specific embodiments. However, this explanation and description do not constitute an undue limitation on the technical solution of this utility model.

[0023] Testing power tools directly affects their normal performance. All functions of a power tool must pass testing to meet the product's functional requirements and ensure a high-quality user experience. Therefore, all functions of the power tool must be tested before it leaves the factory.

[0024] Currently, testing devices exist for evaluating the various functions of power tools. However, these tests need to be conducted on multiple independently set up testing units, requiring dedicated operators and ultimately leading to excessively high product manufacturing costs. Furthermore, the manual operation of testing and material handling results in low work efficiency. In addition, multiple independently set up testing units occupy a significant amount of space on the production floor.

[0025] To address this issue, this invention provides a testing production line in one embodiment that can save significant space with a simple layout and perform various tests on power tools.

[0026] Figure 1 The layout of the test production line described in this utility model is schematically shown in one embodiment from a top-down perspective.

[0027] like Figure 1 As shown, in some embodiments, the test production line includes a production line 100 arranged end-to-end, which includes a fixed main frame 101.

[0028] like Figure 1 As shown, in some more specific embodiments, the connecting production lines 100 can be arranged in a U-shape 300 (e.g., Figure 1 (As shown in the red rectangle).

[0029] In some other, more specific embodiments, the end-to-end assembly line 100 may also be in the form of a ring, or a pentagon, a hexagon, or other similar end-to-end shape.

[0030] like Figure 1As shown, several first test stations 110 are arranged in sequence on the main frame of the first phase-continuous assembly line, and the first test stations 110 are connected by conveying devices 130, and the electric tools to be tested are transferred between the first test stations by the conveying devices. In addition, at least one second test station 120 is arranged beside the assembly line 100. A conveying device 200 is arranged in association with the at least one second test station to convey the electric tools to be tested between the second test station 120 and the assembly line.

[0031] In some more specific embodiments, the conveying device can be a conveying roller. In some other more specific embodiments, the conveying device can be a conveying belt or a conveying chain.

[0032] In some more specific embodiments, as shown, Figure 1 As shown, the first test station 110 can include a loading and unloading station 111, and at least one of an identity recognition station 114, a visual detection station 112, an assembly station 113, an aging station 115, and a tool chuck test station 116.

[0033] It should be noted that, although Figure 1 The first test stations in the above embodiment are arranged in a certain order, which is only an exemplary description, and the order of the first test stations is not limited in the utility model.

[0034] According to the above arrangement, the tests on the electric tools to be tested can be completed on one assembly line, and the electric tools to be tested are transferred between different test stations by the conveying roller and the conveying device.

[0035] In addition, the second test station is arranged beside the assembly line in the utility model, because some test stations will bring negative feedback to the whole assembly line, in order to avoid the tests on some test stations from affecting the assembly line, the tests that affect the assembly line are arranged on the second test station, which can improve the test accuracy of the whole assembly line. For example, the impact test of the electric grabber will produce violent vibration, if the electric grabber to be tested is directly placed on one of the first test stations of the assembly line for testing, the vibration caused by the test will easily damage the main frame of the assembly line, the conveying device and other test devices on the assembly line, and will also affect the test operation of other first test stations. For another example, the high-voltage test of the electric grabber requires a high-voltage environment of 2500V, once the test station has a test problem, it will easily affect other test stations and the assembly line, so it is recommended to be arranged on the second test station beside the assembly line.

[0036] It should be noted that, in the utility model, the side of the assembly line refers to a position away from the assembly line.

[0037] As shown in Figure 1 some more specific embodiments, there can be at least one second test station 121 arranged beside the flow line 100 in the horizontal direction.

[0038] In addition, as shown in Figure 1 some more specific embodiments, there can be at least one second test station 122 arranged beside the flow line 100 in the vertical direction.

[0039] As shown in Figure 1 some more specific embodiments, the conveying device 200 comprises a telescopic arm assembly extending in the horizontal direction, which is capable of telescoping between the flow line 100 and the second test station 121 arranged beside the flow line in the horizontal direction, so as to convey the electric power tool to be tested between the flow line 100 and the second test station.

[0040] In some more specific embodiments, as shown in Figure 1 the telescopic arm assembly can comprise a fixedly arranged servo motor 220, and a telescopic arm 210, the leading end of which is connected to the servo motor 220, so as to be driven by the servo motor 220 to telescope between the flow line 100 and the second test station, and the trailing end of the telescopic arm is provided with a gripper for clamping and picking up the electric power tool to be tested.

[0041] In some more specific embodiments, the gripper can be a mechanical hand or other device capable of picking up and clamping in the art.

[0042] As shown in Figure 1 some more specific embodiments, in order to further save the floor space, the servo motor 220 can be arranged within the area P1 enclosed by the flow line 100, and the second test station is arranged outside the area enclosed by the flow line, which not only saves the floor space, but also facilitates the operator to operate at the second test station.

[0043] In some more specific embodiments, the second test station 121 arranged beside the flow line can comprise an impact test station, so as to avoid the impact vibration from affecting other test stations on the flow line.

[0044] In some more specific embodiments, at least one second test station 122 is arranged beside the flow line 100 in the vertical direction.

[0045] For example, as shown in Figure 1 and Figure 2 the second test station 122 is arranged above the flow line 100.

[0046] In some more specific embodiments, a second testing station located beside the production line 100 in the height direction may include a high-pressure testing station.

[0047] The high-voltage testing station is used to apply high voltage to the power tool under test to check for leakage. Due to the testing posture at the high-voltage testing station, the power tool needs to be clamped and held firmly from both above and below during testing. Therefore, the high-voltage testing station is located above the production line. When testing is required, the power tool enters the testing station from below. This maximizes the use of space above the production line, reduces floor space, simplifies clamping at the testing station, and ensures the shortest possible transport path, thereby reducing equipment costs.

[0048] Furthermore, in some embodiments, the testing line also includes a lifting device. Figure 2 (Not shown in the image), it conveys the power tool Q to be tested between the production line 100 and a second test station 122 located beside the production line in the height direction. For example, it is hidden below the production line 100. When the power tool to be tested needs to be tested at the second test station 122 located beside the production line in the height direction, the lifting device lifts the power tool Q to be tested upward to the second test station.

[0049] In some more specific embodiments, the lifting device may be a cylinder assembly or a hydraulic cylinder assembly. In other more specific embodiments, the lifting device may also be an electrically controlled mechanical lifting device.

[0050] like Figure 1 As shown, in some more specific embodiments, the test line may also include several trays 140 for placing power tools to be tested, which are conveyed along the line 100 via a conveyor 130.

[0051] In some more specific embodiments, tooling may be provided on the tray 140 for clamping the power tool to be tested, and the tray may be transferred to each test station by a conveyor. Each test station may be provided with an obstruction device, such as a stop, to limit the follow-up relationship between the tray and the conveyor when testing is required, to prevent the conveyor from accidentally starting and taking the tray away, and to ensure the integrity of the test at each station.

[0052] In some specific embodiments, the power tool to be tested may be an electric pick, while in other embodiments it may be an electric hammer, electric drill, angle grinder, circular saw or other power tool to be tested.

[0053] In one specific example, the loading and unloading station 111, the visual inspection station 112, the assembly station 113, the identity recognition station 114, the aging station 115 and the tool chuck test station 116 as the first test stations are sequentially arranged on the flow line 100 in a head-to-tail manner, and the electric pole to be tested is placed in the tray 120 and transferred between the first test stations under the conveying of the conveying device 130, forming a circulation loop. One of the second test stations 121 arranged on the side of the flow line 100 in the horizontal direction is an impact test station (or a hammer test station), and one of the second test stations 122 arranged on the side of the flow line in the vertical direction is a high-voltage test station.

[0054] When the electric pole is tested:

[0055] The operator places the electric pole semi-finished product in the tray of the loading and unloading station 111 and presses the start button, and the tray is automatically fed into the visual inspection station 112, where the appearance of the electric pole semi-finished product is imaged by the image acquisition device to detect the power line installation state of the electric pole semi-finished product. After the visual inspection is qualified, the tray is automatically fed into the assembly station 113, and the operator manually assembles the chuck and handle at this station. After the assembly is completed, the start button is pressed, and the tray is automatically fed into the identity recognition station by the conveying device. The identity code on the electric pole is scanned at this position. Then, the tray is transferred to the aging station, where the electric pole is tested for idling. After aging, the tray is conveyed to the side of the impact test station by the conveying device, the tray is sent from the flow line to the impact test station by the conveying device for impact test, the tray is pulled out of the impact test station by the conveying device after the impact test is completed, and the tray is fed into the next chuck test station 116 on the flow line for testing the chuck of the electric pole. After the chuck test is completed, the tray is sent to the lower side of the high-voltage test station by the conveying device, the tray is lifted to the high-voltage test station by the lifting device to test whether the electric pole is electrified. After the high-voltage test is completed, the tray is sent back to the flow line by the lifting device and flows back to the loading and unloading station under the action of the conveying device, completing a test cycle.

[0056] With the test flow line, only the loading and unloading station and the assembly station need to be equipped with operators, and the remaining stations can complete automatic operation, thereby reducing labor costs and worker burden.

[0057] It should be noted that the present application mainly improves the layout of the test flow line and the relative positions of the devices, and does not improve the test devices, so the structure, operation process and test process of the test devices are not described again. Based on the understanding of the existing test devices, those skilled in the art can realize the technical scheme.

[0058] It can be seen from the above description that the test pipeline can greatly save the land occupation space of the test device, improve the test efficiency and save the process operation cost by optimizing the layout
