Description

Technical Field

[0001] This utility model relates to an auxiliary placement fixture, specifically an auxiliary placement fixture for an LED placement machine. Background Technology

[0002] LED chip mounters are a type of surface mount technology equipment primarily used to precisely mount LED chips (or other electronic components) onto designated locations on printed circuit boards (boards). They are one of the core pieces of equipment in the production of LED lighting, displays, backlight modules, and other products. During the mounting process, multiple auxiliary fixtures are required to improve mounting accuracy; these include support fixtures and inspection fixtures.

[0003] Common support fixtures include a mounting frame (fixed at both ends to the pick-and-place machine); a support frame is slidably mounted on the mounting frame, and the support frame is movable; the board material is conveyed to the support frame by a conveying device (and clamped by a clamping assembly), and the board material is moved by the movement of the support frame, so that the pick-and-place machine can perform dynamic placement actions during the movement of the board material; and the support and fastening effects of the support frame and the clamping assembly improve the placement accuracy.

[0004] Typically, the surface of the support frame that contacts the sheet material has a high degree of smoothness (to prevent friction damage to the sheet material). Therefore, when the conveying device transfers the sheet material to the support frame, its resting position is uncertain due to inertial acceleration (the sheet material will slide a certain distance on the support frame, causing a deviation between its resting position and the preset position). In daily production, the conveying speed of the conveying device is often controlled to reduce the inertia of the sheet material. Although this can solve the problem, it leads to a decrease in production efficiency. While using a fixed limiting device can achieve precise positioning of the sheet material, it will affect the subsequent unloading of the sheet material. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary mounting fixture for an LED chip mounter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An auxiliary mounting fixture for an LED chip mounter includes a mounting frame; Guide rails are fixedly mounted on the mounting frame; It also includes a movable frame; multiple sets of sliders that slide and engage with the guide rail are fixedly installed on the movable frame; A positioning plate, which is used to position the sheet material; It also includes clamping elements, including pressure plates that can approach or move away from the movable frame to clamp or release the sheet metal; A movable component, which can drive the movable frame to move along the length direction of the mounting frame; It also includes a clearance member, which can cause the limiting plate to descend or rise when the moving member moves.

[0007] As described above, the auxiliary mounting fixture for the LED chip mounter includes: a clamping motor fixedly mounted on the moving frame; a rotating shaft fixedly mounted on the output end of the clamping motor; a second inclined groove formed on the rotating shaft; a connecting rod on the moving frame; a fixed sleeve fixedly mounted on the connecting rod and sleeved to the rotating shaft; a protruding post fixedly mounted inside the fixed sleeve and slidably engaged with the second inclined groove; sliding plates fixedly mounted at both ends of the connecting rod; and the sliding plates slidably connected to the moving frame and connected to the pressure plate.

[0008] As described above, the LED chip mounter auxiliary mounting fixture includes multiple sets of telescopic columns fixedly mounted on the slide plate, and multiple sets of telescopic sleeves that slide and engage with the telescopic columns are fixedly mounted on the pressure plate. Each telescopic sleeve contains a spring, and the two ends of the spring abut against the telescopic column and the pressure plate, respectively.

[0009] As described above, the auxiliary mounting fixture for the LED chip mounter includes a moving motor fixedly mounted on the mounting frame, and a lead screw fixedly mounted on the output end of the moving motor; a threaded sleeve threadedly connected to the lead screw is fixedly mounted on the moving frame.

[0010] As described above, the auxiliary mounting fixture for the LED chip mounter includes: a clearance component comprising a vertical groove formed on the movable frame; a sliding post fixedly mounted on the limiting plate and slidably engaging with the vertical groove; and a set of grooves formed on the mounting frame and slidably engaging with the sliding post.

[0011] As described above, the LED chip mounter auxiliary mounting fixture includes a first horizontal slot, a first inclined slot, and a second horizontal slot; wherein the two ends of the first inclined slot are respectively connected to one end of the first horizontal slot and one end of the second horizontal slot.

[0012] As described above, the auxiliary mounting fixture for the LED chip mounter has multiple sets of protrusions fixedly mounted on the pressure plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by positioning the board with a limiting plate, the relative sliding of the board during the separation of the board from the conveying device can be avoided, which would cause the board to shift position, thereby improving the accuracy of LED mounting; during the movement of the moving frame, the locating component will move, thereby causing the limiting plate to descend, so as to facilitate the subsequent separation of the board from the moving frame. Moreover, during the descent of the limiting plate, the squeezing force of the limiting plate on the board is small, which will not cause the board to shift during the mounting process, thereby avoiding affecting the accuracy of mounting.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-6 As an embodiment of the present utility model, the LED chip mounter auxiliary mounting fixture includes a mounting frame 1; A guide rail 104 is fixedly mounted on the mounting frame 1; It also includes a movable frame 2; multiple sets of sliders 3 that slide and engage with the guide rail 104 are fixedly installed on the movable frame 2; The limiting plate 13 is used to position the plate material. It also includes clamping components, including a pressure plate 5, which can approach or move away from the movable frame 2 to clamp or release the sheet metal; A movable component, which can drive the movable frame 2 to move along the length direction of the mounting frame 1; It also includes a clearance member, which can cause the limiting plate 13 to descend or rise when the moving member moves.

[0023] In this embodiment, both ends of the mounting frame 1 are fixedly connected to the pick and place machine (set along the moving direction of the conveying device on the pick and place machine); the board material conveyed by the conveying device can be conveyed to the moving frame 2; and after the moving component drives the moving frame 2 to move from one end of the mounting frame 1 to the other end, the conveying device can move the board material to transfer the board material; during the movement of the moving frame 2, the pick and place device of the pick and place machine can place the LED components on the board material.

[0024] When the board moves onto the moving frame 2, it will come into contact with the limiting plate 13. The limiting plate 13 positions the board, which can prevent relative sliding during the separation of the board from the conveying device and thus avoid the board position from shifting, thereby improving the accuracy of LED mounting.

[0025] After the board is positioned, the clamping component moves, bringing the pressure plate 5 closer to the moving frame 2. The pressure plate 5 clamps the board on the moving frame 2, thus securing the board to the moving frame 2. This prevents the dynamic contact between the moving board and the mounting device during LED mounting from causing the board to shift position, and further improves the accuracy of mounting.

[0026] After the board is secured, the moving frame 2 is moved from one end of the mounting frame 1 to the other by the moving component, thereby moving the board synchronously to assist the mounting device in mounting the LEDs.

[0027] Furthermore, during the movement of the moving frame 2, it will cause the displacement component to move, thereby causing the limiting plate 13 to descend, so as to facilitate the subsequent separation of the plate and the moving frame 2. During the descent of the limiting plate 13, the limiting plate 13 exerts less pressure on the plate, which will not cause the plate to shift during the patching process, thus avoiding affecting the accuracy of the patching.

[0028] As a further embodiment of this utility model, the clamping component includes a clamping motor 8 fixedly mounted on the movable frame 2, a rotating shaft 9 fixedly mounted on the output end of the clamping motor 8, and a second inclined groove 901 formed on the rotating shaft 9; a connecting rod 7 is provided on the movable frame 2, and a fixed sleeve 701 that is sleeved with the rotating shaft 9 is fixedly mounted on the connecting rod 7, and a protruding post 702 that slides and engages with the second inclined groove 901 is fixedly mounted inside the fixed sleeve 701; a sliding plate 4 is fixedly mounted on both ends of the connecting rod 7; and the sliding plate 4 is slidably connected to the movable frame 2 and connected to the pressure plate 5.

[0029] In this embodiment, after the plate is positioned by the limiting plate 13, the clamping motor 8 will be activated, thereby driving the rotating shaft 9 to rotate, which in turn drives the second inclined groove 901 to rotate.

[0030] The rotating shaft 9 will cause the second inclined groove 901 to slide and engage with the protruding column 702. Through the squeezing action of the groove wall of the second inclined groove 901 on the protruding column 702, the fixed sleeve 701 can be moved closer to the moving frame 2 (downward). Then, through the connecting rod 7, the slide plate 4 is driven to slide downward on the moving frame 2, so as to move the pressure plate 5, gradually shortening the distance between the pressure plate 5 and the moving frame 2, thereby clamping the board. This can avoid the dynamic contact between the moving board and the mounting device during the LED mounting process, which would cause the board position to shift, and can further improve the accuracy of the mounting.

[0031] When the moving frame 2 moves to the end of the mounting frame 1, the clamping motor 8 will rotate in the opposite direction, thereby driving the slide plate 4 to move upward on the moving frame 2, so as to drive the pressure plate 5 to move, thereby increasing the distance between the pressure plate 5 and the moving frame 2, thereby releasing the plate, which facilitates the transfer of the plate by the conveying device, and also facilitates the clamping of the next plate.

[0032] As a further embodiment of this utility model, the clamping member also includes multiple sets of telescopic columns 401 fixedly installed on the slide plate 4, and multiple sets of telescopic sleeves 501 that slide and engage with the telescopic columns 401 are fixedly installed on the pressure plate 5. A spring 6 is provided inside the telescopic sleeve 501, and the two ends of the spring 6 abut against the telescopic column 401 and the pressure plate 5 respectively.

[0033] In this embodiment, when the slide plate 4 moves downward, it will be driven by the elastic force of the spring 6 to bring the pressure plate 5 closer to the plate. After the pressure plate 5 contacts the plate, the slide plate 4 continues to move, thereby driving the telescopic column 401 to slide inward in the telescopic sleeve 501 and compress the spring 6. The plate is clamped by the elastic force of the spring 6, which can effectively prevent the plate from being damaged due to excessive pressure.

[0034] When the slide plate 4 moves upward, it first causes the telescopic column 401 to slide outward within the telescopic sleeve 501, thereby causing the spring 6 to return to its original position. Then, as the slide plate 4 continues to move, it causes the pressure plate 5 to move synchronously to release the plate.

[0035] As a further embodiment of this utility model, the moving component includes a moving motor 10 fixedly mounted on the mounting frame 1, and a lead screw 11 fixedly mounted on the output end of the moving motor 10; a threaded sleeve 12 that is threadedly connected to the lead screw 11 is fixedly mounted on the moving frame 2.

[0036] In this embodiment, after the plate is fastened to the movable frame 2, the movable motor 10 rotates, thereby driving the lead screw 11 to rotate synchronously. Through the threaded engagement, the threaded sleeve 12 can be driven to move along the length direction of the lead screw 11, so as to drive the movable frame 2 to move from one end to the other end on the mounting frame 1. During this process, the slider 3 will slide on the guide rail 104 to reduce the resistance of the movable frame 2.

[0037] The moving frame 2 moves the board material, and the mounting device mounts the LED components during the movement, which can effectively ensure the mounting efficiency.

[0038] After the conveying device separates the plate from the moving frame 2, the moving motor 10 rotates in the opposite direction to reset the moving frame 2.

[0039] As a further embodiment of this utility model, the clearance member includes a vertical groove 201 formed on the movable frame 2; a sliding column 1301 that slides and engages with the vertical groove 201 is fixedly installed on the limiting plate 13; and a set of grooves that slide and engage with the sliding column 1301 are formed on the mounting frame 1.

[0040] As a further embodiment of this utility model, the groove group includes a first horizontal groove 101, a first inclined groove 102, and a second horizontal groove 103; wherein the two ends of the first inclined groove 102 are respectively connected to one end of the first horizontal groove 101 and one end of the second horizontal groove 103.

[0041] In this embodiment, as the moving frame 2 moves from one end of the mounting frame 1 to the other, the moving frame 2 will drive the limiting plate 13 to move synchronously through the squeezing action of the vertical groove 201 and the sliding column 1301. Therefore, the squeezing force between the limiting plate 13 and the board is small during the movement of the limiting plate 13, which will not cause the board to shift during the patching process, thereby avoiding affecting the accuracy of the patching.

[0042] Furthermore, during the movement of the limiting plate 13, it will cause the sliding column 1301 to slide in the groove group. The sliding column 1301 will first slide in the first horizontal groove 101, at which time the height of the limiting plate 13 remains unchanged. Then the sliding column 1301 will slide in the first inclined groove 102. At this time, through the squeezing action of the groove wall of the first inclined groove 102, the sliding column 1301 can be driven to slide downward in the vertical groove 201, thereby causing the limiting plate 13 to move downward to make way. Then the sliding column 1301 will slide in the second horizontal groove 103 to maintain the position of the limiting plate 13. Thus, at the end of the mounting frame 1, it is convenient for the conveying device to transfer the plate. The resistance during the transfer process is small, which can avoid damage to the plate and LED components.

[0043] During the reset process of the movable frame 2, the limiting plate 13 will gradually move upward to reset, thereby facilitating the positioning of the next plate.

[0044] As a further improvement of this utility model, multiple sets of protrusions are fixedly installed on the pressure plate 5.

[0045] In this embodiment, the bump can increase the resistance to relative sliding between the plate and the pressure plate 5, which can effectively prevent the plate from moving. That is, it can prevent the dynamic contact between the moving plate and the mounting device during the LED mounting process from causing the plate position to shift, which can further improve the mounting accuracy.

[0046] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
