Detailed Implementation

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a dual-moving high-precision visual positioning adhesive spraying device for camera module packaging. The dual-moving high-precision visual positioning adhesive spraying device for camera module packaging includes a processing component 1, a transmission component 2, and a positioning component 3. By setting the positioning component 3, after the material is transmitted to the set position, the lifting and moving operation is completed to meet the subsequent adhesive spraying processing requirements. During the lifting process of the material, a negative pressure environment can be formed simultaneously, so that the product is tightly attached, ensuring the quality of subsequent adhesive spraying. At the same time, pre-positioning and locking can be performed, which is conducive to subsequent stable clamping and stable unloading after adhesive spraying, which is more in line with actual processing requirements.

[0039] Specifically, the processing component 1 includes a housing 11, a three-axis drive component 12 is provided inside the housing 11, and a glue spraying head 13 is fixed to the moving end of the three-axis drive component 12.

[0040] Specifically, the transmission component 2 is disposed inside the housing 11 and includes a transmission frame 21 fixed inside the housing 11. A belt transmission mechanism 22 is installed on the transmission frame 21, and a support bar 23 is fixed on one side of the transmission frame 21.

[0041] Specifically, the positioning component 3 is located on the outside of the transmission frame 21, including a fixed frame 31 fixed to the housing 11. A clamping component 32 is provided on the top of the fixed frame 31, and a placement component 33 is provided on the top of the fixed frame 31. A lifting component 34 is provided at the bottom center of the fixed frame 31, including a lifting cylinder 341 located inside the fixed frame 31. A displacement frame 343 is fixed to the output end of the lifting cylinder 341. A support plate 348 is fixed to the top of the displacement frame 343. A protruding rod 3481 is fixed to the top of the support plate 348. A tray 346 is provided on the top of the displacement frame 343. An air-guiding component 344 is provided between the displacement frame 343 and the tray 346. A second spring 349 is fixed between the displacement frame 343 and the tray 346. A clamping component 347 is provided on the top of the tray 346.

[0042] The clamping component 32 can lock the placement component 33 after it has been moved up, ensuring the position of the mold 331 and meeting the requirements of subsequent glue spraying.

[0043] The lifting component 34 can lift and raise the placement component 33 while using a negative pressure environment to ensure that the product fits tightly against the placement component 33 and locks the placement component 33, thereby improving the stability of the placement component 33's position and facilitating subsequent stable downward movement and unloading.

[0044] Example 2, refer to Figures 2 to 15 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0045] Specifically, the clamping component 32 includes a small cylinder 321 fixed to the top of the fixed frame 31. The output end of the small cylinder 321 is fixed with a clamping plate 322, which cooperates with the placement component 33. A limiting component 323 is provided on the top of the clamping plate 322.

[0046] When the small cylinder 321 extends to work, it will drive the clamping plate 322 to move stably and match with the placement part 33, thus completing the positioning and clamping of both sides of the placement part 33 and ensuring the stability of the position of the placement part 33.

[0047] Specifically, the limiting component 323 includes a limiting block 3231 slidably connected to the top of the clamping plate 322. The limiting block 3231 has a guide groove 32311 on its top. The clamping plate 322 has a guide block 3232 fixed on its top. The guide block 3232 is slidably connected in the guide groove 32311. The clamping plate 322 has a fixing block 3234 fixed on its top. A first spring 3233 is fixed on one side of the limiting block 3231. The other end of the first spring 3233 is fixed on the fixing block 3234.

[0048] By setting the guide block 3232 and the guide groove 32311, the positioning and guiding functions can be achieved, which not only improves the sliding stability of the limit block 3231, but also limits the displacement stroke of the limit block 3231.

[0049] Specifically, the placement component 33 includes a mold 331 located on top of the tray 346. The mold 331 has a mold groove 3311 inside, and a product groove 3312 is formed at the top of the mold groove 3311. A slot 3315 is formed between two adjacent product grooves 3312. A locking strip 332 is fitted in the slot 3315. A limiting groove 3314 is formed on the top side of the mold 331 and is slidably connected to a limiting block 3231. Positioning holes 3313 are formed at the four corners of the top of the mold 331.

[0050] The product slot 3312 is larger than the mold slot 3311. The product slot 3312 meets the product placement requirements in the camera module, while preventing the product from falling through the mold slot 3311.

[0051] The top space of the mold 331 can be divided by the slot 3315 and the strip 332 to meet the regional placement requirements of multiple camera module products, thereby creating a processing environment for subsequent glue spraying.

[0052] Specifically, the top of the displacement frame 343 is provided with a storage groove 3431, and vertical grooves 3432 are provided on both sides of the storage groove 3431.

[0053] Specifically, the air intake component 344 includes a support rod 3441 fixed to the bottom of the receiving groove 3431. An auxiliary shell 3443 is fixed to the top of the support rod 3441. Sealing blocks 3444 are slidably connected to both sides of the auxiliary shell 3443. The sealing blocks 3444 are hollow. A third spring 34441 is fixed to the inner wall of the sealing block 3444. The other end of the third spring 34441 is fixed inside the auxiliary shell 3443.

[0054] Specifically, the air intake component 344 also includes a hollow shell 3442 fixed to the bottom of the tray 346. A first air valve 34421 is fixed to the top of one side of the hollow shell 3442. The end of the sealing block 3444 away from the auxiliary shell 3443 is slidably connected to the hollow shell 3442, and the sealing block 3444 and the hollow shell 3442 are sealed. A second air valve 3446 is fixed to the bottom of one side of the hollow shell 3442. A telescopic hose 3445 is fixed to the bottom of the other side of the hollow shell 3442. A groove 3461 is opened on the top of the tray 346. The other end of the telescopic hose 3445 is fixed to the tray 346 and communicates with the groove 3461.

[0055] The connection between the sealing block 3444 and the auxiliary shell 3443 is sealed. (See attached drawings.) Figure 13 In the middle, the third spring 34441 is in a compressed state. At this time, as the auxiliary shell 3443 moves upward, under the elastic support of the third spring 34441, the sealing block 3444 can always be kept in close contact with the inner wall of the hollow shell 3442, which has a good sealing effect. The gas in the hollow shell 3442 and the space at the top of the auxiliary shell 3443 is discharged, and the space in the hollow shell 3442 and the space at the bottom of the auxiliary shell 3443 forms a negative pressure state. Under the transmission of the telescopic hose 3445, the gas in the mold groove 3311 can be adsorbed, ensuring that the product is in close contact with the mold 331.

[0056] The storage slot 3431 can meet the storage space requirements of the hollow shell 3442, and the vertical slot 3432 can meet the displacement space requirements of the second air valve 3446 and the telescopic hose 3445.

[0057] Specifically, the clamping member 347 includes a fixing cylinder 3471 fixed to the top of the tray 346, and the fixing cylinder 3471 is slidably connected in the positioning hole 3313. The outer ring of the fixing cylinder 3471 is provided with a through groove 34711, and an anti-slip member 3472 is provided in the through groove 34711.

[0058] Specifically, the anti-slip component 3472 includes an anti-slip plate 34721 slidably connected in the through groove 34711. The anti-slip plate 34721 has an inclined groove 34722 on its inner side. A fourth spring 34723 is fixed to the top of one side of the anti-slip plate 34721, and the other end of the fourth spring 34723 is fixed to the fixed cylinder 3471.

[0059] As shown in the attached diagram of the instruction manual. Figure 15 As shown, the top of the protrusion 3481 is conical. This design allows the protrusion 3481 to contact the inclined groove 34722 first when it moves upward, thereby simultaneously squeezing multiple anti-slip plates 34721 outward. The multiple anti-slip plates 34721 tightly abut against the inner wall of the positioning hole 3313, thus ensuring the stability of the position of the mold 331.

[0060] As shown in the attached diagram of the instruction manual. Figure 15 As shown, the fourth spring 34723 is in a stretched state. Under the elastic connection of the fourth spring 34723, the anti-slip plate 34721 is kept in a retracted state when no external force is applied.

[0061] Example 3, referring to Figures 2 to 15 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0062] Specifically, the three-axis drive unit 12 includes a drive element (motor), a transmission mechanism (lead screw), a guide mechanism (linear guide rail), a control system, and a sensing and limiting device. Its function is to achieve precise three-dimensional positioning through the coordinated motion of the X / Y / Z axes, flexibly adjust the position of the spray head 13, adapt to the spraying requirements of complex workpieces, improve the quality and efficiency of spraying, and ensure the safe and stable operation of the equipment. It is the core of automated high-precision spraying. The working principle of this part is all existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0063] The belt transmission mechanism 22 consists of a drive transmission system (servo motor, synchronous belt), a guide support system (precision guide rail), and a sensing control system (encoder). Its core function is to achieve precise linear positioning of the mold 331, improve the quality and efficiency of glue spraying, and adapt to clean, anti-static, and complex environments. The working principle of this part is existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0064] The support bar 23 is placed below the synchronous belt in the belt transmission mechanism 22, and plays a supporting role, which can prevent the synchronous belt from being excessively deformed and affecting the transmission tension and transmission accuracy.

[0065] The number of clamping parts 32 is two, and they are symmetrically distributed on the fixed frame 31.

[0066] A guide bar is fixed to the top of the fixed frame 31. The guide bar passes through the clamping plate 322 and is slidably connected to the clamping plate 322. This design can greatly improve the displacement stability of the clamping plate 322.

[0067] As shown in the attached diagram of the instruction manual. Figure 9 As shown, one side of the limiting block 3231 is a horizontal bar, one end of which passes through the fixing block 3234 and is slidably connected to the fixing block 3234. The first spring 3233 is sleeved on the horizontal bar to avoid the bending of the first spring 3233 itself from affecting the elastic support performance. At the same time, under the support of the first spring 3233, the limiting block 3231 is always in a protruding position without the action of external force.

[0068] As shown in the attached diagram of the instruction manual. Figure 9 As shown, the guide block 3232 has a T-shaped design. This design can prevent the limit block 3231 from tilting up and ensure the stability of the limit block 3231's movement.

[0069] Specifically, a base 345 is bolted to the top of the housing 11, the lifting cylinder 341 is bolted to the top of the base 345, a protective shell 342 is fixed to the top of the base 345 and outside the lifting cylinder 341, and the displacement frame 343 is slidably connected to the protective shell 342.

[0070] The protective shell 342 not only shields and protects the lifting cylinder 341 from accidental pressure damage, but also positions and guides the vertical movement of the displacement frame 343, ensuring the stability of the displacement frame 343's operation.

[0071] There are two first air valves 34421, which are symmetrically distributed on the front and rear sides of the hollow shell 3442. One of the first air valves 34421 is a one-way air inlet valve, and the other first air valve 34421 is a one-way air outlet valve (with a filter screen at the air inlet end). During the upward movement of the auxiliary shell 3443, the gas at the top of the hollow shell 3442 is discharged through the one-way air outlet valve. When the auxiliary shell 3443 moves downward, the outside gas is replenished into the hollow shell 3442 through the one-way air inlet valve.

[0072] In practical applications, different specifications of hollow shells 3442 can be flexibly selected according to the weight of the camera module product, so that when the auxiliary shell 3443 moves upward, its bottom negative pressure space is larger and the negative pressure is stronger, which is used to perform stronger adsorption and adjustment on multiple products.

[0073] As shown in the attached diagram of the instruction manual. Figure 11 As shown, a sealing rubber strip is embedded on the top of the tray 346 and outside the groove 3461. It is used to move the tray 346 up and contact the mold 331, so as to seal and protect the connection between the two and prevent gas from seeping in or out at will.

[0074] In practical applications, the top of the displacement frame 343 is provided with a round hole, and the bottom of the second spring 349 is fixed in the round hole. The design of the round hole can provide storage space for the second spring 349 when the displacement frame 343 moves up and fits against the tray 346.

[0075] In use, the products in the camera module are pre-placed in the product slot 3312 and divided into different glue spraying areas by the clamping strip 332. The mold 331 carrying the products is placed on the belt conveyor mechanism 22 and is linearly transported by the belt conveyor mechanism 22. After the mold 331 is transported to the processing position, the lifting component 34 extends to lift the mold 331 to a fixed height. The clamping component 32 actively locks the mold 331. Then, through the cooperation of the three-axis drive component 12 and the glue spraying head 13, multiple products on the mold 331 are glued.

[0076] During the above process, as the lifting component 34 extends, under the elastic support of the second spring 349, the tray 346 first contacts the mold 331, and the clamping component 347 is placed into the positioning hole 3313. As the lifting component 34 extends further, it will lift the mold 331 away from the belt transmission mechanism 22 and move upward. Finally, with the cooperation of the protruding limiting block 3231 and the limiting groove 3314, the rising height of the mold 331 is limited.

[0077] As the lifting component 34 extends further into operation, the pallet 346 and the mold 331 can no longer move upwards, and the displacement frame 343 gradually moves away from the pallet 346, causing the distance between them to gradually decrease. The second spring 349 is compressed until the displacement frame 343 and the pallet 346 are in contact, completing the negative pressure adsorption and outward expansion locking.

[0078] During the above process, as the displacement frame 343 gradually approaches the second spring 349, the auxiliary shell 3443 moves upward synchronously. Under the elastic support of the third spring 34441, the two sealing blocks 3444 remain in contact with the inner wall of the hollow shell 3442, which can expel the gas from the upper part of the hollow shell 3442. A negative pressure space is naturally formed below the hollow shell 3442. Due to product transmission and processing vibration, there are gaps between some products and the mold groove 3311, and between the products and the product groove 3312. At this time, under the action of atmospheric pressure, the gas enters the lower part of the hollow shell 3442 through the gaps, the groove 3461 and the telescopic hose 3445, and the products are returned to their original position and fit well with the mold groove 3311 and the product groove 3312.

[0079] At the same time, the support plate 348 and the protruding rod 3481 move upward together with the displacement frame 343. The support plate 348 first contacts the inclined groove 34722, while the multiple anti-slip plates 34721 move outward at the same time. The fourth spring 34723 is stretched, and the multiple anti-slip plates 34721 press against the positioning hole 3313 to ensure the height of the mold 331. It should be noted that this step occurs before the clamping part 32 locks the mold 331, which can play a role in pre-positioning and is conducive to the clamping plate 322 locking the mold 331 well.

[0080] After the camera module product is glued, the lifting component 34 is lowered. At this time, the protruding rod 3481 is still placed in the fixed cylinder 3471. Due to the friction, the downward movement of the displacement frame 343 will synchronously drive the mold 331 to move down, ensuring the stability of unloading. Since the mold 331 is larger than the tray 346 (as shown in the attached diagram of the instruction manual), Figure 14 As shown in the diagram, the mold 331 moves down and gradually comes into contact with the belt transmission mechanism 22, and is supported by the support bar 23. Then, the mold 331 is disassembled and placed on the belt transmission mechanism 22, and finally moved out by the belt transmission mechanism 22.
