Technical Field
[0001] This utility model belongs to the field of coil manufacturing and processing, specifically, it relates to a multi-station pull-out force testing device. Background Technology
[0002] In zoom cameras of electronic products (such as smartphones, security monitoring equipment, etc.), the line load body usually refers to the key structure or material used to support, fix or drive optical components (such as lenses, sensors, etc.).
[0003] After the wire load is manufactured, it needs to be tested for its pull-out force using a tensile testing tool to determine whether its strength is up to standard. However, conventional tensile testing devices are usually individual units, which means that after multiple workers have conducted the tests, each wire load tested by a worker needs to be collected one by one. Since each wire load is relatively small, there is a high probability that some will be lost during the collection process.
[0004] In view of this, this utility model is hereby proposed. Utility Model Content

The rear wall surface of the moving plate can be in contact with the frame wall surface. The detector is fixedly connected to the front wall surface of the moving plate. The limiting groove is symmetrically opened on both sides of the moving plate. The moving frame is slidably connected to the wall surface of the moving plate. The slider is slidably connected in each limiting groove. The trigger plate is fixedly connected to the bottom of the rear wall surface of the moving frame.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0027] like Figure 1 , Figure 2 and Figure 3As shown, a multi-station pull-out force testing device includes: a base plate 20, which is rectangular; a placement head 24 is fixedly connected to the top of the base plate 20, the placement head 24 being composed of a rectangular block and a semi-cylinder at the front; a frame 21 is fixedly connected to the top of the rear wall of the base plate 20, the frame 21 being an inverted L-shaped support; a worm gear 22 is rotatably connected to the bottom of the frame 21, the worm gear 22 being a cylindrical part with threads on an arc surface; the top of the worm gear 22 can pass through the wall of the frame 21. A handle is installed at the top, and a limit post is fixedly connected to the front of the worm gear 22. A detector 23 is provided on the wall of the worm gear 22, and a similar placement head 24 is fixedly connected to the bottom of the detector 23. The placement head 24 at the bottom of the detector 23 and the placement head 24 at the top of the substrate 20 are symmetrical to each other. The bottom end of the worm gear 22 is rotatably connected to the top of the substrate 20. The detector 23 uses the existing technology of the SF-500 push-pull force gauge, which is existing technology and will not be described in detail here.
[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a centralized structure is set on the rear wall of the substrate 20 for collecting the tested workpieces. The centralized structure includes a centralized plate 30, a positioning post 31, and a collection box 32. The centralized plate 30 is fixedly connected to the rear wall of the substrate 20, the positioning post 31 is fixedly connected to the top of the centralized plate 30, and the collection box 32 is detachably connected to the top of the centralized plate 30. The centralized plate 30 is a rectangular plate, and the same substrate 20, frame 21, worm gear 22, detector 23, and placement head 24 are respectively arranged on the four sides of the centralized plate 30.
[0029] like Figure 1 , Figure 2 and Figure 3As shown, the positioning posts 31 are L-shaped columns, and the collection box 32 is a rectangular box with an open top and a hollow interior. The same positioning posts 31 are evenly arranged at the four corners of the top of the concentrating plate 30. The inner corner of each positioning post 31 can fit against the edge of the collection box 32. The concentrating structure also includes a partition plate 33, a feeding slot 34, and a protruding plate 35. The partition plate 33 is fixedly connected to the cavity of the collection box 32. The feeding slot 34 is opened at the edge of the collection box 32. The protruding plate 35 is fixedly connected to the wall of the collection box 32 at each feeding slot 34. The partition plate 33 is a cross-shaped plate that divides the cavity of the collection box 32 into four separate spaces. The feeding slot 34 has a rectangular opening, and the protruding plate 35 is a rectangular plate. Four feeding slots 34 are evenly opened on the wall of the collection box 32, and each feeding slot 34 can fit against the edge of the cavity of the collection box 32. The spaces at each corresponding position are connected. The convex plate 35 is located in the spacing between each group of adjacent frames 21. Each worm 22 wall is provided with an anti-detachment structure. The anti-detachment structure includes: a moving plate 40, a limiting groove 41, a moving frame 42, a slider 43, a trigger plate 44, and a shielding plate 45. The moving plate 40 is threadedly connected to the arc surface of the worm 22. The limiting post on the wall of the frame 21 can also pass through the wall of the moving plate 40. The rear wall of the moving plate 40 can be in contact with the wall of the frame 21. The detector 23 is fixedly connected to the front wall of the moving plate 40. The limiting groove 41 is symmetrically opened on both sides of the moving plate 40. The moving frame 42 is slidably connected to the wall of the moving plate 40. The slider 43 is slidably connected in each limiting groove 41. The trigger plate 44 is fixedly connected to the bottom of the rear wall of the moving frame 42. The shielding plate 45 is fixedly connected to the bottom of the front wall of the moving frame 42.
[0030] In practical use, the worm gear 22 is first rotated by turning the handle at the top of the worm gear 22. As the worm gear 22 rotates, it causes the shift plate 40 to move downwards. The shift plate 40, in turn, causes the detector 23 to move synchronously. After the placement head 24 at the bottom of the detector 23 contacts the wall of the placement head 24 at the top of the substrate 20, the semi-cylinders of the symmetrical placement heads 24 form a complete cylinder. Before the symmetrical placement heads 24 contact each other, the bottom of the trigger plate 44 contacts the bottom of the substrate 20. During this process, the shift frame 42, the slider 43, and the shielding plate 45 are affected by the trigger plate 44. The movement stops upon contact with the substrate 20, but the shift plate 40 still causes the detector 23 to gradually move downwards. After the symmetrical placement heads 24 contact, the shielding plate 45 is located at the top of the front wall of the upper placement head 24 and does not block the placement head 24. After the upper and lower symmetrical placement heads 24 contact, the line loading body to be detected is fitted onto the overlapping cylinder of the symmetrical placement heads 24. After the fitting is completed, the handle at the top of the worm gear 22 is controlled to drive the shift plate 40 to move upwards and backwards. As the shift plate 40 moves upwards, it drives the detector 23 to move synchronously. When the device moves, it causes the bottom mounting head 24 to move as well. At this time, the distance between the symmetrical mounting heads 24 gradually increases. The wire loading system attached to the walls of the symmetrical mounting heads 24 exerts a pulling force on the bottom of the detector 23. The pulling force measured by the detector 23 is displayed on its screen. As the moving plate 40 moves upward, the trigger plate 44 also moves synchronously. When the moving plate 40 moves the trigger plate 44 away from the substrate 20, the trigger plate 44, due to gravity, causes the moving frame 42 to move downward. As the moving frame 42 moves downward, it causes the slider 43 to slide along the limiting groove 41. The shielding plate 45 will move downwards synchronously to block the front wall of the placement head 24 below the detector 23. After the online loading body is detected, the moving plate 40 will move the detector 23 downwards and remove the detected online loading body from the wall of the symmetrical placement head 24 and put it into the corresponding loading slot 34 along the top of the convex plate 35. At this time, the detected online loading body will be stored in the cavity of the collection box 32 at the corresponding position. When it is necessary to collect the detected online loading body, the collection box 32 can be directly removed from the top of the concentrating plate 30, and then the online loading body stored in the cavity of the collection box 32 can be poured out directly.
[0031] In summary, by setting up a centralized structure, not only can the wire loads after testing be collected in a centralized manner, thus facilitating the processing of the wire loads and preventing loss, but the wire loads tested at each workstation can also be stored separately in the collection box 32. This not only facilitates the processing of wire loads but also prevents them from being lost. Furthermore, the separate storage method can also prevent workers at each workstation from shirking their duties.
[0032] like Figure 1 , Figure 2, Figure 3 , Figure 4 and Figure 5 As shown, the moving plate 40 is a plate with a right-angled cross section. The limiting groove 41 is located on both sides of the front wall of the moving plate 40. The limiting groove 41 can accommodate the sliding of the slider 43. The slider 43 is a rectangular block. The moving frame 42 is a rectangular frame. The detector 23 is located in the cavity of the moving frame 42. The trigger plate 44 and the moving frame 42 are rectangular plates. The length of the trigger plate 44 is greater than that of the shielding plate 45. The rear wall of the shielding plate 45 can contact the placement head 24 on the wall of the detector 23.
[0033] In practical use, after the worm gear 22 is connected, the handle at the top of the worm gear 22 is controlled to move the moving plate 40 upward and backward. As the moving plate 40 moves upward, the detector 23 moves synchronously. As the detector 23 moves, the placement head 24 at its bottom moves. At this time, the distance between the symmetrical placement heads 24 gradually increases. The line loading body connected to the wall of the symmetrical placement head 24 will bring a pulling force to the bottom of the detector 23. The pulling force measured by the detector 23 will be displayed on its display screen. As the moving plate 40 moves upward, the trigger plate 44 will also move synchronously. As the moving plate 40 moves the trigger plate 44 away from the substrate 20, the trigger plate 44 will move the moving frame 42 downward due to gravity. When the moving frame 42 moves downward, it will move the slider 43 along the limiting groove 41 and simultaneously move the blocking plate 45 downward to block the front wall of the placement head 24 below the detector 23.
[0034] In summary, by setting up an anti-detachment structure, the frame 42 can be moved automatically by gravity during the testing of the wire load, and the shielding plate 45 can be used to shield the wire load to prevent it from falling off and flying away during the test. It can also automatically give way when placing the wire load to prevent obstruction of the placement of the wire load.
[0035] Working principle: First, the worm gear 22 is rotated by turning the handle at the top. As the worm gear 22 rotates, it drives the shift plate 40 to move downwards. The shift plate 40, in turn, moves the detector 23 synchronously. After the placement head 24 at the bottom of the detector 23 contacts the wall of the placement head 24 at the top of the substrate 20, the semi-cylinders of the symmetrical placement heads 24 form a complete cylinder. Before the symmetrical placement heads 24 contact each other, the bottom of the trigger plate 44 contacts the bottom of the substrate 20. During this process, the shift frame 42, slider 43, and baffle plate 45 move due to the contact between the trigger plate 44 and the substrate 20. The plate 20 stops moving due to contact, but the moving plate 40 still drives the detector 23 to gradually move downwards. After the symmetrical placement heads 24 contact, the shielding plate 45 will be located at the top of the front wall of the upper placement head 24 and will not block the placement head 24. After the upper and lower symmetrical placement heads 24 contact, the line loading body to be detected is sleeved on the overlapping cylinder of the symmetrical placement heads 24. After the sleeve is completed, the handle at the top of the worm gear 22 is controlled to drive the moving plate 40 to move upwards and backwards. As the moving plate 40 moves upwards, it will drive the detector 23 to move synchronously. When the device moves, it will cause the bottom placement head 24 to move, and at this time, the distance between the upper and lower symmetrical placement heads 24 will gradually increase. The wire loading body fitted on the wall of the symmetrical placement head 24 will bring a pulling force to the bottom of the detector 23, and the pulling force measured by the detector 23 will be displayed on its display screen. As the moving plate 40 moves upward, the trigger plate 44 will also move synchronously. When the moving plate 40 moves the trigger plate 44 away from the substrate 20, the trigger plate 44 will cause the moving frame 42 to move downward due to gravity. When the moving frame 42 moves downward, it will cause the slider 43 to slide along the limiting groove 41. The shielding plate 45 moves downwards synchronously to block the front wall of the placement head 24 below the detector 23. After the online loading body is detected, the moving plate 40 moves the detector 23 downwards and removes the detected online loading body from the wall of the symmetrical placement head 24 and puts it into the corresponding loading slot 34 along the top of the convex plate 35. At this time, the detected online loading body will be stored in the cavity of the collection box 32 at the corresponding position. When it is necessary to collect the detected online loading body, the collection box 32 is directly removed from the top of the concentrator plate 30, and then the online loading body stored in the cavity of the collection box 32 can be poured out directly.
