Description

Technical Field

[0001] This invention relates to the field of component bonding technology, and in particular to a component bonding device and method for assembling optical modules. Background Technology

[0002] In the assembly of optical modules for some cameras, this is often encountered, such as Figure 1 Small components 101 are glued (attached) to the top of component 100, typically 3-5 in number, to assemble from part A to part B. These small components 101 are generally made of metal or are magnets. The shape of the components 101 varies depending on the optical module model, being either rectangular or rhomboid. For example, if rhomboid... Figure 1 That is, the side of the material 100, which is the inclined side 102.

[0003] In order to improve the bonding efficiency and yield of small material block 101 and material part 100, the bonding is generally carried out by mechanical equipment. After the worker places the material part 100 and small material block 101 in the designated position, the bonding is carried out by mechanical automation.

[0004] Because the optical module itself is small and is a precision component, the size of the material 100 and the small block 101 is relatively small, especially the small block 101, which is generally only a few millimeters to a dozen millimeters in length. The bonding accuracy requirements are also high. However, with existing bonding equipment, when the worker places the material 100 and the small block 101 in the designated position, the position will inevitably have an error. At this time, the equipment cannot determine the position of the material 100 and the small block 101 before picking up and pasting the materials. In particular, the small block 101 is not easy to position flexibly, which greatly reduces the bonding accuracy in the later stage. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art that it is impossible to determine the position of the material 100 and the small material block 101, especially the small material block 101 which is small in size and is not easy to position flexibly, resulting in a significant reduction in the bonding accuracy in the later stage. Therefore, this invention proposes a part bonding device and method for optical module assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An optical module assembly component bonding device includes a worktable and further includes: a clamping assembly for fixing components; a placement table with a placement groove for positioning small components, the small components being placed in the placement groove; a picking and bonding assembly for bonding the small components to the components; and a first detection camera for capturing the position of the components and small components.

[0007] Preferably, the two intersecting sides of the placement groove are set as positioning boundaries; when multiple small blocks are restricted by the positioning boundaries, there is still room for movement in the length and width directions of the placement groove.

[0008] Preferably, when multiple small blocks arranged side by side are restricted by positioning boundaries, each group of small blocks has a negative pressure port at its bottom.

[0009] Preferably, the material handling and adhesion assembly includes a lifting cylinder; a dispensing head and an adsorption head are fixedly installed at the output end of the lifting cylinder; the first detection camera is also installed at the output end of the lifting cylinder; a first drive module is installed on the workbench, and the lifting cylinder is installed at the moving end of the first drive module.

[0010] Preferably, a drive motor is fixedly installed at the output end of the lifting cylinder, and the drive motor is used to drive the adsorption head to rotate horizontally.

[0011] Preferably, the clamping assembly includes a clamping platform; a clamping rod is slidably connected to the clamping platform, and an elastic element is provided between the clamping rod and the clamping platform; a contact surface is provided on the clamping platform, and the clamping rod, under the action of the elastic element, causes the material to be contacted with the contact surface.

[0012] Preferably, a second drive module is installed on the workbench, and the moving end of the second drive module is fixedly connected to a moving platform; both the clamping platform and the placement platform are fixed on the moving platform.

[0013] Preferably, the sidewall of the bonding surface is provided with a clearance area; the material is bonded to both sides of the clearance area.

[0014] Preferably, the material picking and sticking component and the material clamping component are both designed as two corresponding sets.

[0015] A method for bonding components used in assembling an optical module, comprising the following steps: S1: Secure the material to the clamping assembly; S2: Place multiple small blocks in the placement slot and position them accordingly; S3: Determine the location of the component and small block using the first detection camera; S4: Pick up small material blocks through the material picking and bonding component and bond them to the material.

[0016] Compared with the prior art, the present invention provides a device and method for bonding parts for assembling optical modules, which has the following advantages: 1. This liquid-gas separation mechanism, through the design of the placement slot, can automatically position small material blocks, reducing the error of manual placement. In addition, before grabbing the small material blocks, the position of the material and small material blocks is accurately determined by the second shooting of the first detection camera. Then, the small material blocks are grabbed and accurately adhered to the designated position of the material by the material picking and bonding component, which greatly improves the bonding accuracy. 2. In this liquid-gas separation mechanism, when workers place multiple small blocks side by side into the placement tank, the workers can manually or through a material-pushing plate push the small blocks toward the positioning boundary so that they fit against it, thereby achieving the purpose of quickly and flexibly positioning the small blocks. 3. The liquid-gas separation mechanism features an air-avoidance zone design. When retrieving materials, the worker manually pulls the clamping rod to detach it from the material, and then uses the other hand to pick it up from the two vertical edges at the front and back, thus avoiding contact with small material blocks on both sides and preventing displacement.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Example 1:

[0022] like Figure 1 This equipment is used to attach multiple small material blocks 101, usually 3-5, but in this case, 4 are assembled, to the upper surface of the material 100.

[0023] Then, the small block 101 is a rhombus-shaped block with inclined sides, that is, hypotenuse 102.

[0024] Reference Figures 2-11 An optical module assembly component bonding device includes a housing 200 and a worktable 201. The worktable 201 is located on the housing 200. The device also includes: a clamping assembly 400 for fixing the component 100; a placement table 500 with a placement groove 501 for positioning small component blocks 101, where the small component blocks 101 are placed; and a picking and bonding assembly 300 for bonding the small component blocks 101 to the component 100.

[0025] The material handling and adhesion assembly 300 and the clamping assembly 400 are both installed on the worktable 201.

[0026] The material picking and bonding assembly 300 is also equipped with a first detection camera 307 for capturing the position of the material 100 and the small material block 101. The first detection camera 307 is a CCD camera commonly used in industry.

[0027] During the bonding process, the worker first fixes the material 100 onto the clamping assembly 400, and then places multiple small material blocks 101 side by side in the placement groove 501. In this case, there are four small blocks. The positioning function is used to flexibly position the small material blocks 101 to ensure the bonding accuracy in the later stage.

[0028] Then, the first detection camera 307 on the material picking and bonding component 300 accurately photographs the precise position of the material 100 and the small material block 101 again to overcome the error of manual material placement, that is, the placement of the material 100 and the small material block 101.

[0029] After knowing the precise positions of the material 100 and the small material block 101, the material picking and bonding component 300 picks up each small material block 101 and then precisely bonds it to the designated position on the upper surface of the material 100.

[0030] By designing the placement slot 501, the small material block 101 can be automatically positioned, reducing the error of manual placement. Furthermore, before picking up the small material block 101, the position of the material 100 and the small material block 101 can be accurately determined by taking another picture through the first detection camera 307. Then, the small material block 101 is picked up and accurately adhered to the designated position of the material 100 by the material picking and bonding component 300, which greatly improves the bonding accuracy.

[0031] like Figure 10 and Figure 11 The two intersecting sides of the placement groove 501 are set as positioning boundaries 503. The side of the placement groove 501 is a vertical surface. The positioning boundary 503 is also the side of the placement groove 501 and the side of the small material block 101, which is also a vertical surface.

[0032] When multiple side-by-side small material blocks 101 are restricted by the positioning boundary 503, their placement slots 501 still have room to move in the length and width directions; that is to say, if Figure 11 When four small blocks 101 are placed side by side into the placement groove 501 and their sides are attached to the positioning boundary 503, the placement groove 501 has a certain amount of room to move in both the width and length directions away from the small blocks 101.

[0033] When workers place multiple small blocks 101 side by side into the placement groove 501, they manually or by using a pusher plate to push the small blocks 101 toward the positioning boundary 503 so that they fit against it, thereby achieving the purpose of quickly and flexibly positioning the small blocks 101.

[0034] When multiple small material blocks 101 arranged side by side are restricted by the positioning boundary 503, each group of small material blocks 101 has a negative pressure port 502 below it. In this case, there are 4 negative pressure ports 502, each connected to an independent negative pressure pump through a pipe.

[0035] When multiple small blocks 101 are placed side by side into the placement groove 501, the negative pressure port 502 generates negative pressure, adsorbing the small blocks 101 and preventing accidental movement; when a single small block 101 is subsequently taken out by the material picking and bonding component 300, the negative pressure port 502 at the bottom of the small block 101 is cut off and loses its adsorption capacity, while the negative pressure ports 502 at the bottom of the remaining small blocks 101 adsorb normally.

[0036] like Figure 4 , Figure 8 , Figure 9 The material handling and bonding component 300 includes a lifting cylinder 301, the output end of which moves vertically up and down; a dispensing head 303 and an adsorption head 305 are fixedly installed at the output end of the lifting cylinder 301. Specifically, a mounting frame 302 is fixedly connected to the output end of the lifting cylinder 301, the dispensing head 303 and the adsorption head 305 are mounted on the mounting frame 302, the dispensing head 303 is connected to the glue through a pipe, and the adsorption head 305 is connected to the negative pressure pump through a pipe. In addition, a curing lamp 306 is also installed on the mounting frame 302.

[0037] A first drive module 203 is installed on the workbench 201, and a lifting cylinder 301 is installed on the moving end of the first drive module 203, such as... Figure 3 and Figure 4 The moving end of the first driving module 203 moves left and right.

[0038] The first drive module 203 can be an electric slide, a cylinder, or a motor that drives a lead screw and then a ball screw pair. Its moving end drives the lifting cylinder 301 to move as a whole, which in turn drives the entire material picking and bonding assembly 300.

[0039] The first detection camera 307 is also installed at the output end of the lifting cylinder 301, and the first detection camera 307 is installed on the mounting bracket 302.

[0040] The first detection camera 307, dispensing head 303, adsorption head 305, material 100, and small material block 101 are all on the same straight line.

[0041] During operation, the first drive module 203 moves the first detection camera 307 above the material 100 and the small material block 101 to accurately capture their positions. Then, the first drive module 203 continues to drive the material picking and bonding component 300 to move, moving the dispensing head 303 above the material 100. The height of the dispensing head 303 is controlled by the lifting cylinder 301 to dispense adhesive onto the upper surface of the material 100. Then, the lifting cylinder 301 is retracted, and the first drive module 203 moves the suction head 305 again. Move the device above the small material block 101, and use the lifting cylinder 301 to make its adsorption head 305 adhere to the upper surface of the small material block 101, then adsorb. Then, the negative pressure port 502 at the bottom of the corresponding small material block 101 is cut off, grab the small material block 101, and then move it to the corresponding position of the material part 100 for adhesion. At this time, the adsorption head 305 continues to press on the small material block 101 to maintain pressure for 3-5 seconds. At the same time, turn on the curing lamp 306 to irradiate the adhesion area for curing. Then release the adsorption head 305 to complete the adhesion of this small material block 101.

[0042] Then apply glue to the next area to be bonded, and repeat the process.

[0043] A drive motor 304 is fixedly installed at the output end of the lifting cylinder 301. The drive motor 304 is used to drive the adsorption head 305 to rotate horizontally. Specifically, the output end of the drive motor 304 is vertically downward and fixedly connected to the adsorption head 305.

[0044] When the first detection camera 307 detects a horizontal angle deviation in the small material block 101, the drive motor 304 drives the small material block 101 to rotate, thereby correcting the horizontal angle and improving the adhesion accuracy.

[0045] like Figures 3-7 The clamping assembly 400 includes a clamping platform 402; clamping rods 403 are slidably connected on the clamping platform 402, and there are 10-20 clamping rods 403. An elastic element 404 is provided between the clamping rods 403 and the clamping platform 402. The elastic element 404 is a spring and is sleeved on the clamping rods 403.

[0046] The clamping table 402 is provided with a contact surface 406. Under the action of the elastic element 404, the clamping rod 403 makes the material 100 fit against the contact surface 406. That is, the worker first manually pulls the clamping rod 403, then fits the material 100 against the contact surface 406, and then releases the clamping rod 403. Under the action of the elastic element 404, the clamping rod 403 presses against the material 100, making it fit against the contact surface 406, thus achieving the purpose of clamping and fixing the material.

[0047] The bonding surface 406 consists of a horizontal surface and a vertical surface.

[0048] A second drive module 204 is installed on the workbench 201. The moving end of the second drive module 204 is fixedly connected to a movable stage 401. The second drive module 204 can be an electric slide, a cylinder, or a motor driven by a lead screw, which in turn is driven by a ball screw pair. It drives the movable stage 401 to move, such as... Figure 4 and Figure 5 The mobile station 401 moves back and forth, meaning that its direction of movement is perpendicular to the direction of movement of the first drive module 203.

[0049] Both the clamping stage 402 and the placement stage 500 are fixed on the moving stage 401.

[0050] like Figure 6 A fixing plate 600 is detachably and fixedly connected to the clamping table 402 by bolts. A clamping rod 403 passes through and slides on the fixing plate 600. A stop block 602 is fixed on the clamping rod 403. An elastic element 404 is sleeved between the stop block 602 and the fixing plate 600.

[0051] The middle area of ​​the clamping platform 402, which is the area between the fixing plate 600 and the mating surface 406, is designed with an inner groove 603, and the elastic element 404 is located in this area.

[0052] One end of the clamping rod 403 extends out of the fixing plate 600 and is fixedly connected to the drive head 601, making it easy for the staff to manually pull the clamping rod 403.

[0053] The clamping rod 403 has a clamping head 405 at one end near the contact surface 406, which clamps the material 100.

[0054] The clamping rod 403, clamping head 405, and drive head 601 are integrally formed.

[0055] like Figure 6 and Figure 7 The side wall of the bonding surface 406 is provided with a clearance area 407, which is an inwardly extending groove. The material 100 is bonded to both sides of the clearance area 407. This design is to address the situation where the material 100 is rhomboid, that is, it has an inclined side 102. In this case, if the worker picks up the material directly from the inclined side 102, the material 100 is easily tilted during the picking process because of its tilted shape. Then, when the fingers touch the small material blocks 101 on both sides, the small material blocks 101 are easily displaced because the adhesive is not yet fully firm.

[0056] With the design of the clearance zone 407, when picking up materials, the worker can manually pull the clamping rod 403 to detach it from the material 100, and then use the other hand to pick it up from the front and back vertical edges of the material 100, thus avoiding contact with the small material blocks 101 on both sides and causing them to shift.

[0057] During material handling, the second drive module 204 moves the clamping assembly 400 to the edge of the worktable 201 for easy material handling.

[0058] The material picking and bonding component 300 and the clamping component 400 are both designed in two sets. Similarly, the corresponding first drive module 203 and second drive module 204 are also designed in two sets. The two sets of material picking and bonding components 300 and clamping components 400 can improve the bonding efficiency.

[0059] A support frame 202 is fixedly installed on the workbench 201, and two sets of first drive modules 203 are both installed on the support frame 202.

[0060] In addition, a second detection camera 700 is installed on the workbench 201. The second detection camera 700 is also a CCD camera, which is on the same straight line as the dispensing head 303 and the suction head 305. It is used to check the status of the dispensing head 303 and the suction head 305, such as whether the suction head 305 is broken and whether there is residual glue at the outlet of the dispensing head 303.

[0061] Example 2

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
