Description

Technical Field

[0001] This utility model relates to the field of lens mounting machine technology, and in particular to a worktable for a lens mounting machine. Background Technology

[0002] In LED lighting structures, lenses are typically mounted onto LED chips to focus the light source. Multiple LED chips are soldered onto a circuit board, with each LED chip corresponding to a lens. To improve production efficiency, a lens mounting machine has been developed that can automatically complete the dispensing and lens mounting processes on the circuit board. Before operation, the positions of four positioning blocks on the worktable are adjusted according to the size of the circuit board. The circuit board is then placed within the area enclosed by the positioning blocks to define its placement.

[0003] On most lens mounting machines, the positioning blocks are fixed to the worktable with screws. The worktable has multiple screw holes arranged in a matrix, and the positioning blocks are installed in different screw holes to adjust their position. This installation structure means that during adjustment, multiple positioning blocks must be removed one by one for each adjustment, and then screwed back in to fix the position, which is cumbersome.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a worktable for a lens mounting machine, which aims to solve the technical problem of cumbersome steps in adjusting the position of the positioning block in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A worktable for a lens mounting machine, comprising:

[0008] The worktable has an adjustment groove extending along its length.

[0009] Two positioning blocks are slidably mounted on the adjustment groove and their positions are locked by a locking assembly. The positioning blocks are provided with vertically arranged positioning pins, which are used to insert into the positioning holes of the circuit board.

[0010] A first guide rail, on which a first slide block is slidably connected;

[0011] A clamping spring is used, with one end connected to the first slide and the other end used to clamp the circuit board.

[0012] Furthermore, the top of the adjusting groove is provided with a first step and the bottom of the groove is provided with a second step; the positioning block is slidably connected to the first step, and the locking assembly includes a locking plate and a first screw for connecting the locking plate and the positioning block, and the locking plate is used to press against the second step.

[0013] Furthermore, the width of the locking piece is smaller than the width of the adjusting groove, and the length of the locking piece is larger than the width of the second step.

[0014] Furthermore, the locking piece has two rounded corners arranged diagonally; the end of the locking piece has a notch, which is located away from the rounded corners, and the bottom of the positioning block has a limiting block, which abuts against the notch to restrict the locking piece from rotating in the opposite direction.

[0015] Furthermore, a pressure strip is provided at the end of the clamping spring away from the first slide block.

[0016] Furthermore, it also includes a second guide rail and a second slide block. The second guide rail is located on the side of the worktable away from the first guide rail, and the first guide rail and the second guide rail are symmetrically arranged. The two second slide blocks are slidably connected to the first guide rail and the second guide rail respectively. Each second slide block is movably connected to a pressure rod, which is used to press the anti-leakage paper tightly onto the worktable.

[0017] Furthermore, pulleys are provided at both ends of the pressure rod, and a vertical plate is fixed on the second slide block. An upwardly inclined groove is opened on the vertical plate, and the pulley is slidably connected to the groove.

[0018] Furthermore, the peripheral wall of the pressure rod is provided with textures extending along its length.

[0019] Furthermore, it also includes an X-axis linear module, a Y-axis linear module, and a fixing plate. The X-axis linear module is used to be mounted on the frame of the lens mounting machine, the Y-axis linear module is located at the output end of the X-axis linear module, the fixing plate is located at the output end of the Y-axis linear module, and the worktable is located on the fixing plate.

[0020] Beneficial effects:

[0021] This invention provides a worktable for a lens mounting machine. Two adjustable positioning blocks are installed on the slide groove of the worktable. Adjustment is achieved by loosening the first screw, moving the positioning block to the desired position, and then tightening the first screw. This causes a locking plate to press against the second step, locking the positioning block in place. The operation is simple and quick, allowing for rapid adjustment of the positioning block's position to locate circuit boards of different sizes. Furthermore, a positioning pin inserted into a positioning hole and a clamping spring pressing against the side of the circuit board ensures stable installation. Attached Figure Description

Detailed Implementation

[0031] This utility model provides a worktable for a lens mounting machine. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0032] Please see Figures 1 to 7As shown, this utility model provides a worktable for a lens mounting machine, including a worktable 1, two positioning blocks 2, a first guide rail 12, and a clamping spring 5; the worktable 1 has an adjustment groove 11 extending along its length direction; the two positioning blocks 2 are slidably disposed on the adjustment groove 11 and are locked in position by a locking assembly 3, and the positioning blocks 2 are provided with vertically arranged positioning pins 4, which are used to insert into the positioning holes of the circuit board; a first slide block 13 is slidably connected to the first guide rail 12; one end of the clamping spring 5 is connected to the first slide block 13, and the other end is used to clamp the circuit board.

[0033] Circuit board a to be mounted with lens, such as Figure 8 As shown, it includes a substrate a1 and several LED beads a2 soldered on the substrate a1. Several positioning holes a3 are opened on the side of the substrate, and positioning pins 4 can be inserted into the positioning holes a3 to define the position of the circuit board a.

[0034] During adjustment, loosen the locking assembly 3 and slide the positioning block 2 along the adjustment groove 11 so that the positioning pins 4 on the two positioning blocks 2 correspond to the positions of the positioning holes a3 on the substrate a1. Then, operate the locking assembly 3 to lock the position of the positioning block 2 and adjust the position of the first slide block 13 on the first guide rail 12 so that the clamping spring 5 is located next to the circuit board a. Finally, in each lens mounting process, simply place the circuit board a on the worktable 1, insert the positioning pins 4 into the positioning holes a3, and press the clamping spring 5 against the side of the circuit board a.

[0035] By inserting two positioning pins 4 into the positioning holes a3 and pressing the circuit board a from top to bottom with the clamping spring 5, the position of the circuit board a can be defined. For circuit boards of different sizes, the position of the positioning block 2 on the adjustment groove 11 can be adjusted according to the position of the positioning holes on the circuit board. The operation is simple and quick, and it can be used to position circuit boards of various sizes.

[0036] In a preferred embodiment, see [reference] Figure 3 , 4 The adjusting groove 11 has a first step 111 at its top and a second step 112 at its bottom, giving the adjusting groove 11 an "I"-shaped cross-section. The positioning block 2 is slidably connected to the first step 111. The locking assembly 3 includes a locking plate 31 and a first screw 32 for connecting the locking plate 31 and the positioning block 2. The locking plate 31 is pressed against the second step 112. The first screw 32 passes through the positioning block 2 and is threadedly connected to the locking plate 31. Tightening the first screw 32 presses the locking plate 31 against the second step 112, achieving quick locking of the positioning block 2. Similarly, loosening the first screw 32 allows the positioning block 2 to move.

[0037] Further, see Figure 5The width of the locking piece 31 is smaller than the width of the adjusting groove 11, and the length of the locking piece 31 is larger than the width of the second step portion 112. When the first screw 32 is screwed in, the locking piece 31 first rotates with the first screw 32. After the end of the locking piece 31 is engaged with the side wall of the second step portion 112, the locking piece 31 is threaded with the first screw 32, and the locking piece 31 moves upward along the first screw 32 and presses against the second step portion 112. Conversely, when the first screw 32 is screwed out, the locking piece 31 no longer presses against the second step portion 112 and rotates in the opposite direction with the first screw 32. When the long side of the locking piece 31 is parallel to the long side of the adjusting groove 11, since the width of the locking piece 31 is smaller than the width of the adjusting groove 11, the positioning block 2 can be directly removed. When removed, the positioning block 2, the first screw 32, and the locking piece 31 are an integral structure, which facilitates the installation, removal, and position locking of the positioning block 2.

[0038] Preferably, see Figure 4 , 5 The locking piece 31 has two rounded corner portions 311 arranged diagonally, which facilitates the locking of the corners of the locking piece 31 and keeps it away from the inner wall of the second step portion 112. The locking piece 31 has a notch 312 at its end, which is located away from the rounded corner portion 311. The bottom of the positioning block 2 is provided with a limiting block 21. The notch 312 abuts against the limiting block 21 to restrict the locking piece 31 from rotating in the opposite direction. When the first screw 32 is unscrewed, the locking piece 31 rotates with the first screw 32. After the notch 312 abuts against the limiting block 21, the long side of the locking piece 31 is parallel to the long side of the adjusting groove 11, which facilitates the removal of the positioning block 2.

[0039] Preferably, the adjusting groove 11 is configured as a series of short grooves spaced apart. Based on the position of the positioning holes on the circuit board, the positioning block 2 is placed in the corresponding short groove, and the clamping spring 5 is pressed against the position between two adjacent short grooves. This configuration provides better support for the sides of the circuit board, and the clamping spring 5 acts on the supported sides of the circuit board, ensuring stable placement.

[0040] In the above, the connection between the positioning pin 4 and the positioning block 2 can be an interference fit fixed connection to achieve stable installation of the positioning pin 4.

[0041] In a preferred embodiment, see [reference] Figure 1 , 6 The end of the clamping spring 5 away from the first slide block 13 is provided with a pressure strip 51. Specifically, one end of the clamping spring 5 is fixed to the first slide block 13 by the second screw 16. By rotating the clamping spring 5, its installation angle can be adjusted so that the pressure strip 51 can be pressed on the side of the circuit board to avoid affecting the lens mounting work.

[0042] Preferably, the material of the pressure strip 51 can be a soft material such as rubber or silicone, which can ensure that the pressure strip 51 can press the circuit board tightly without damaging the surface of the circuit board.

[0043] Preferably, see Figure 6 The end of the clamping spring 5 is provided with a handle 52, which extends upward along the end of the clamping spring 5 to form a "V" shape, which makes it easier for the operator to lift the clamping spring 5 upward.

[0044] In a preferred embodiment, see [reference] Figure 1 , 2 The worktable 1, 7, also includes a second guide rail 14 and a second slide block 15. The second guide rail 14 is located on the side of the worktable 1 away from the first guide rail 12, and the first guide rail 12 and the second guide rail 14 are symmetrically arranged. The two second slide blocks 15 are slidably connected to the first guide rail 12 and the second guide rail 14, respectively. Each second slide block 15 is movably connected to a pressure rod 6, which is used to press the anti-leakage paper 7 firmly onto the worktable 1. In actual operation, when attaching lenses to the end positions of the circuit board, the glue is prone to leaking and dripping onto the outside of the circuit board, thus sticking to the worktable 1. This requires cleaning the worktable 1 surface after each mounting operation. Therefore, by covering the worktable 1 surface with an anti-leakage paper 7, the glue can be caught, saving the subsequent worktable cleaning. In use, adjust the position of the two second slide blocks 15 on the second guide rail 14 so that the pressure rod 6 is close to the end of the circuit board, and then press the anti-leakage paper 7 under the pressure rod 6 to fix one side of the anti-leakage paper 7, while the other side of the anti-leakage paper 7 is pressed by the circuit board.

[0045] In the above description, the first guide rail 12 and the second guide rail 14 can be guide rods with rectangular cross-sections to ensure that the first slide block 13 and the second slide block 15 can only slide along their length direction, and their positions can be locked by screws. The first guide rail 12 and the second guide rail 14 can also be linear guide rails, and the corresponding first slide block 13 and the second slide block 15 are sliders with position locking function to achieve positioning at any position on the linear guide rail.

[0046] See Figure 7 To facilitate the replacement of the leak-proof paper 7, pulleys 61 are provided at both ends of the pressure rod 6. A vertical plate 17 is fixed on the second slide block 15, and an upwardly inclined sliding groove 151 is opened on the vertical plate 17. The pulleys 61 are slidably connected to the sliding groove 151. When the pressure rod 6 is lifted upward, the pulleys 61 slide upward along the sliding groove 151, at which time the leak-proof paper 7 can be replaced; then the pressure rod 6 is released, and the pulleys 61 slide downward along the sliding groove 151 to the bottom of the sliding groove 151 due to the gravity of the pressure rod 6, and the pressure rod 6 presses on the leak-proof paper 7.

[0047] Preferably, the plane at the lower end of the slide groove 151 is lower than the table surface of the worktable 1, ensuring that the pressure rod 6 can fall completely on the worktable 1.

[0048] Furthermore, the peripheral wall of the pressure rod 6 is provided with textures extending along its length to increase the friction between the pressure rod 6 and the workbench 1 surface, thereby ensuring the stability of the anti-leakage paper 7 installation.

[0049] Preferably, the peripheral wall of the pressure rod 6 is fitted with a rubber layer, and the texture is located on the surface of the rubber layer, so that the pressure rod 6 plays a buffering role when it falls on the worktable 1.

[0050] In a preferred embodiment, see [reference] Figure 1 , 2 It also includes an X-axis linear module 8, a Y-axis linear module 81, and a fixing plate 82. The X-axis linear module 8 is mounted on the frame of the lens mounting machine. The Y-axis linear module 81 is located at the output end of the X-axis linear module 8, and the fixing plate 82 is located at the output end of the Y-axis linear module 81. The worktable 1 is located on the fixing plate 82. Through the above arrangement, the worktable 1 can move horizontally along the X and Y axes, so that any position on the circuit board where a lens needs to be mounted can be automatically moved to below the mounting station of the lens mounting machine to achieve automated processing.

[0051] In the above, the X-axis linear module 8 and the Y-axis linear module 81 can adopt a screw and nut transmission mechanism to drive the worktable 1 to move horizontally.

[0052] It is understood that those skilled in the art can make equivalent substitutions or modifications based on the technical solution and inventive concept of this utility model, and all such substitutions or modifications should fall within the protection scope of the appended claims.
