Abstract
Description
Technical Field
[0001] This utility model relates to the field of PIN assembly technology, and in particular to a fully automatic PIN loading device. Background Technology
[0002] Pins are metallic materials used in connectors to conduct electricity (signals). The material for pins is tungsten carbide, also known as cemented carbide. Cemented carbide has high hardness, strength, wear resistance, and corrosion resistance, and is known as the "teeth of industry." It is used to manufacture cutting tools, knives, fittings, and wear-resistant parts, and is widely used in military, aerospace, machining, metallurgy, oil drilling, mining tools, electronic communications, and construction industries.
[0003] However, traditional pin-loading equipment requires manual insertion of the camera back cover into the positioning card holder, followed by a second transport of the card holder to the processing table. Due to the slow pace of manual transport, it is difficult to match the high-speed pin assembly requirements. Furthermore, manual placement may cause misalignment between the card holder and the displacement module on the worktable, affecting the pin insertion accuracy. In addition, repeated transport can easily lead to operator fatigue.
[0004] For example, when workers move the pallet rack back and forth for a long time, they are prone to fatigue. When fatigued, the accuracy and stability of the operation will decrease, which will further increase the risk of operational errors. Specifically, due to reasons such as arm pain and lack of concentration, the operator may place the positioning pallet rack in a less accurate position, resulting in low production efficiency. Utility Model Content
[0005] This utility model discloses a fully automatic PIN loading device, which aims to solve the technical problems of traditional PIN loading devices, which require manual handling of the camera back cover after it is attached to the positioning card holder, and then the card holder needs to be moved to the processing table a second time. Because manual handling is slow and difficult to match the needs of high-speed PIN assembly, manual placement may cause misalignment between the card holder and the displacement module on the worktable, affecting the PIN insertion accuracy. In addition, repeated handling can easily lead to operator fatigue.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A fully automatic PIN loading device includes a worktable with vibrating screens on both sides. A position sensor is installed at the outlet of each vibrating screen. The device further includes: a feeding mechanism located on one outer wall of the worktable, comprising a connecting plate, a support assembly and two second electric telescopic rods on the top outer wall of the connecting plate, mounting frames fixedly connected to the movable ends of the second electric telescopic rods and the top outer wall of the support assembly, a plurality of equally spaced limiting grooves inside the mounting frames, slides engaged with the inner walls of the limiting grooves, four positioning frames engaged with the top outer wall of the slides, a first electric telescopic rod on one outer wall of the worktable, a fixed plate fixedly connected to the movable end of the first electric telescopic rod, and two push plates on one outer wall of the fixed plate; and a moving mechanism located on the top of the worktable.
[0008] The above technical solution can improve pin insertion efficiency, reduce the workload of staff, and decrease labor and time costs. Specifically, the operator first needs to place an appropriate amount of pin material into the vibrating screen in an orderly manner. Then, the vibrating screen is started, and its internal vibration device will begin to work, regularly vibrating and sorting the pins in the screen. Under continuous and stable vibration, the randomly placed pins will gradually arrange themselves according to a specific direction and order, and be discharged orderly and smoothly along the carefully designed discharge port of the vibrating screen. When the pins gradually move to the discharge port with the vibration, the position sensor can quickly and accurately detect their presence. Once a signal is detected, the position sensor will immediately feed this information back to the connected control system. After receiving the signal from the position sensor, the control system will respond quickly and control the vibration in a timely manner. The vibrating screen stops operating, ensuring a stable and precise feeding of the PIN pins at the outlet, providing accurate material supply for subsequent assembly processes. Then, the workers push multiple camera back covers mounted on the positioning frame onto the mounting frame. By extending and retracting the movable end of the second electric telescopic rod, the mounting frame moves up and down in cooperation with the sliding rod and mounting cylinder of the support component, thereby adjusting the position of the mounting frame. This aligns the top slide with the second drive module on the worktable. Then, by extending and retracting the movable end of the first electric telescopic rod, the push plate on the fixed plate pushes the positioning frame relative to the top to the second drive module. The moving mechanism then uses the PIN pins on the vibrating screen to clamp and insert them into the corresponding camera back covers on the positioning frame. The two second drive modules and the moving mechanism work together simultaneously to complete the uninterrupted insertion of the PIN pins into the camera back covers.
[0009] In a preferred embodiment, the moving mechanism includes two clamping components and a connecting frame. One outer wall of the connecting frame is provided with a first driving module. The two clamping components are slidably connected to the first driving module. The two ends of the first driving module are respectively located directly above the discharge ports of the two vibrating screens.
[0010] In this solution, during use, the first drive module drives the two clamping components to move directly above the discharge ports of the two vibratory screens. The two clamping components can simultaneously activate the third electric telescopic rod to extend downwards, thereby using electric grippers to grab PIN needles from the same or different vibratory screens (depending on the actual production situation). Then, after the clamping components move to the needle loading station, they descend vertically and release the PIN needles onto the camera back cover on the slide for insertion. After completion, the clamping components return to the discharge port of the vibratory screen, waiting for the next grab.
[0011] As described above, a fully automatic PIN inserting device includes a worktable with vibrating screens on both sides. A position sensor is located at the outlet of each vibrating screen. The device also includes: a feeding mechanism located on one outer wall of the worktable, comprising a connecting plate, a support assembly and two second electric telescopic rods on the top outer wall of the connecting plate, a mounting frame fixedly connected to the movable end of each second electric telescopic rod and the top outer wall of the support assembly, a plurality of equally spaced limiting grooves inside the mounting frame, a slide table engaged with the inner wall of each limiting groove, four positioning frames engaged with the top outer wall of the slide table, a first electric telescopic rod on one outer wall of the worktable, a fixed plate fixedly connected to the movable end of the first electric telescopic rod, and two push plates on one outer wall of the fixed plate; and a moving mechanism located on the top of the worktable. This fully automatic PIN inserting device provides the technical effects of improving PIN insertion efficiency, reducing the workload of workers, and reducing labor and time costs.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0019] The fully automatic PIN loading device disclosed in this utility model is mainly used in traditional PIN loading devices where the camera back cover is manually attached to the positioning card holder, and then the card holder needs to be moved to the processing table a second time. Since manual back-and-forth movement is slow, it is difficult to match the needs of high-speed PIN assembly. In addition, manual placement may cause misalignment between the card holder and the displacement module on the worktable, affecting the PIN insertion accuracy. Furthermore, repeated movement can easily lead to operator fatigue.
[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A fully automatic PIN loading device includes a workbench 1, with vibrating screens 2 on both sides of the workbench 1. A position sensor 7 is installed at the outlet of the vibrating screens 2. The device also includes: a feeding mechanism located on one outer wall of the workbench 1, comprising a connecting plate 3, a support assembly and two second electric telescopic rods 15 on the top outer wall of the connecting plate 3, a mounting frame 13 fixedly connected to the movable end of the second electric telescopic rod 15 and the top outer wall of the support assembly, a mounting frame 13 having several equidistantly distributed limiting grooves inside, a slide table 14 engaged in the inner wall of the limiting grooves, four positioning frames 10 engaged in the top outer wall of the slide table 14, a first electric telescopic rod 12 on one outer wall of the workbench 1, a fixed plate 6 fixedly connected to the movable end of the first electric telescopic rod 12, and two push plates 11 on one outer wall of the fixed plate 6; and a moving mechanism located on the top of the workbench 1.
[0021] Among them, the two push plates 11 are symmetrically distributed around the center line of the fixed plate 6.
[0022] The top outer wall of the workbench 1 is provided with two second drive modules 9. The slide 14 is slidably connected to the second drive module 9. The second drive module 9 facilitates the movement of the slide 14 to the designated needle insertion position for needle insertion and pushes the slide 14 to the inspection station after needle insertion to complete the quality inspection. It should be noted that the push plate 11 is always at the same height as the second drive module 9.
[0023] In the specific implementation process, the support assembly includes eight mounting cylinders. The bottom outer walls of the two mounting frames 13 are provided with sliding rods 16 near the four corners. The sliding rods 16 are slidably connected to the inner walls of the mounting cylinders. The movable end of the second electric telescopic rod 15 extends and retracts. Through the cooperation of the sliding rods 16 of the support assembly with the mounting cylinders, the vertical movement is transmitted to the mounting frames 13. The sliding rods 16 slide on the inner wall of the mounting cylinders to ensure that the mounting frames 13 only move axially and avoid lateral displacement.
[0024] Specifically, in actual use, the operator first needs to place an appropriate amount of PIN needle material into the vibrating screen 2 in an orderly manner. Then, the vibrating screen 2 is started, and its internal vibration device will begin to work, performing regular vibration and sorting of the PIN needles in the vibrating screen 2. Under the continuous and stable vibration, the randomly placed PIN needles will gradually arrange themselves according to a specific direction and order, and be discharged orderly and smoothly along the carefully designed discharge port of the vibrating screen 2. When the PIN needles gradually move to the discharge port with the vibration, the position sensor 7 can quickly and accurately detect the presence of the PIN needles. Once the signal is detected, the position sensor 7 will immediately feed this information back to the connected control system. After receiving the signal from the position sensor 7, the control system will respond quickly and control the vibrating screen 2 to stop running in time, thereby ensuring that the PIN needles at the discharge port are in a stable and accurate feeding state, providing a precise feed for subsequent assembly processes. With accurate material supply, the staff pushes multiple camera back covers mounted on the positioning frame 10 onto the mounting frame 13. The second electric telescopic rod 15 extends and retracts, causing the mounting frame 13 to move up and down in cooperation with the sliding rod 16 of the support assembly and the mounting cylinder, thereby adjusting the position of the mounting frame 13. This ensures that the top slide 14 is at the same height as the second drive module 9 on the workbench 1. Then, the first electric telescopic rod 12 extends and retracts, causing the push plate 11 on the fixed plate 6 to push the positioning frame 10, which is located on the top layer, onto the second drive module 9. The moving mechanism then uses this to clamp the PIN pins on the vibrating screen 2 and insert them into the camera back covers on the positioning frame 10. The two second drive modules 9 and the moving mechanism work together simultaneously to complete the uninterrupted insertion of PIN pins into the camera back covers. This device improves insertion efficiency, reduces the workload of staff, and lowers labor and time costs.
[0025] Reference Figure 1 , Figure 2 and Figure 5 In a preferred embodiment, the moving mechanism includes two clamping components and a connecting frame 4. One outer wall of the connecting frame 4 is provided with a first driving module 5. The two clamping components are slidably connected to the first driving module 5. The two ends of the first driving module 5 are respectively located directly above the discharge ports of the two vibrating screens 2.
[0026] The clamping assembly includes two moving blocks 8, which are slidably connected to the first drive module 5. An mounting plate 18 is provided on one outer wall of each moving block 8. A third electric telescopic rod 17 is fixedly connected to the top outer wall of the mounting plate 18. The movable end of the third electric telescopic rod 17 passes through the top outer wall of the mounting plate 18 and is fixedly connected to a transmission block. Two electric grippers 19 are provided on the bottom outer wall of the transmission block. Initially, the two clamping assemblies are positioned directly above the discharge ports of the two vibrating screens 2, waiting for the PIN needle to arrive. After the position sensor 7 detects the PIN needle's arrival, the movable end of the third electric telescopic rod 17 drives the transmission block and electric grippers 19 to descend and grab the PIN needle. The clamping assembly moves synchronously to the needle loading station, placing the PIN needle onto the camera's rear shell. After loading, the clamping assembly resets to the discharge port of the vibrating screen 2, waiting for the next round of gripping. The two clamping assemblies can work independently or synchronously, improving the efficiency of PIN needle gripping and loading.
[0027] In practical use, a limiting strip is provided on one outer wall of the mounting plate 18, and the transmission block is slidably connected to the limiting strip. This arrangement makes it convenient for the moving end of the third electric telescopic rod 17 to drive the transmission block to move, while limiting the transmission block to move only along the axial direction of the limiting strip, thus preventing it from rotating or deviating.
[0028] Specifically, in use, the first drive module 5 drives the two clamping components to move directly above the discharge ports of the two vibrating screens 2. The two clamping components can simultaneously activate the third electric telescopic rod 17 to extend downwards, thereby using the electric gripper 19 to grab the same or different PIN needles of the vibrating screens 2 (depending on the actual production situation). Then, after the clamping components move to the needle loading station, they descend vertically and release the PIN needles onto the camera back cover on the slide table 14 for insertion. After completion, the clamping components return to the discharge port of the vibrating screen 2, waiting for the next grab.
[0029] Working Principle: In actual use, the operator first needs to place an appropriate amount of PIN needle material into the vibrating screen 2 in an orderly manner. Then, the vibrating screen 2 is started, and its internal vibration device will begin to work, performing regular vibration and sorting of the PIN needles in the vibrating screen 2. Under the continuous and stable vibration, the randomly placed PIN needles will gradually be arranged according to a specific direction and order, and discharged orderly and smoothly along the carefully designed discharge port of the vibrating screen 2. When the PIN needles gradually move to the discharge port with the vibration, the position sensor 7 can quickly and accurately detect the presence of the PIN needles. Once the signal is detected, the position sensor 7 will immediately feed this information back to the connected control system. After receiving the signal from the position sensor 7, the control system will respond quickly and control the vibrating screen 2 to stop running in time, thereby ensuring that the PIN needles at the discharge port are in a stable and orderly manner. Precise material supply ensures accurate material supply for subsequent assembly processes. Then, workers push multiple camera back covers mounted on positioning frames 10 onto mounting frames 13. The movable end of the second electric telescopic rod 15 extends and retracts, causing the mounting frame 13 to move up and down in cooperation with the sliding rod 16 of the support component and the mounting cylinder, thereby adjusting the position of the mounting frame 13. This makes the sliding table 14 at the top level and the second drive module 9 on the workbench 1 aligned at the same height. Then, the movable end of the first electric telescopic rod 12 extends and retracts, causing the push plate 11 on the fixed plate 6 to push the positioning frame 10 at the top level onto the second drive module 9. The moving mechanism then uses the PIN pins on the vibrating screen 2 to clamp and insert them into the camera back covers on the positioning frame 10. The two second drive modules 9 and the moving mechanism work together simultaneously to complete the uninterrupted insertion of the PIN pins into the camera back covers.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
