Description

Technical Field

[0001] The present invention relates to the field of precision manufacturing technology, and in particular to a processing technology for a lens module base with an ultra-smooth surface terminal. Background Art

[0002] In current manufacturing technology, the process of combining metal terminals with plastic parts is mostly pure metal (ordinary) terminals + injection process. However, for stainless steel mirror metal terminals, this traditional process has obvious shortcomings. Since the terminal surface is mirror-finished, its mirror surface is very susceptible to scratches and crushing in the existing process, which is mainly due to the lack of effective protection measures. During each process operation and production process, the contact between the terminal surface and the mold, equipment or other components may cause mirror damage, so that the surface roughness of the terminal does not meet the requirements and cannot meet the mechanical performance requirements, which in turn affects the testing requirements of the assembled finished product and causes the overall performance of the product to decline. Summary of the invention

[0003] In order to overcome the deficiencies in the prior art, the present invention provides a lens module base processing technology, which can solve the problem that the ultra-smooth surface on the lens module base is easily damaged during the processing.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A lens module base processing technology, the lens module base includes a base body, a contact terminal and a conductive member, the conductive member is partially embedded in the base body, the conductive member includes a second terminal exposed from the base body, the contact terminal is installed on the surface of the base body, and the exposed part of the contact terminal is provided with a super-slip surface;

[0006] The following steps are also included:

[0007] Step 100: stamping a terminal blank with a protective film on its surface to obtain a first transition piece, wherein the first transition piece includes a first outer frame, a central support piece, and a plurality of contact terminals, wherein the plurality of contact terminals are respectively connected to the central support piece, and the central support piece is connected to the first outer frame;

[0008] Step 200: placing the first transition piece into a hydrocarbon cleaning solvent of a hydrocarbon cleaning machine for cleaning and film removal;

[0009] Step 300: using a cutting machine to cut and remove the first outer frame on the first transition piece after demolding;

[0010] Step 400: stamping the conductive blank to obtain a second transition piece, wherein the second transition piece includes a conductive piece and a second outer frame connected to the outer side of the conductive piece;

[0011] Step 500: electroplating the surface of the second transition piece;

[0012] Step 600: welding the first transition piece obtained in step 300 to the second transition piece obtained in step 500 to obtain an assembly, and welding the conductive piece and the contact terminal in the assembly;

[0013] Step 700: partially bend the second transition piece in the assembly using a punching machine to form a second terminal at the bent position;

[0014] Step 800: using an injection molding machine to perform injection molding on the assembly to obtain a base blank;

[0015] Step 900: Cutting the waste material on the base blank to obtain a lens module base.

[0016] In the above technical solution, the ultra-smooth surface is prone to damage during the stamping process. In step 100, by performing film stamping on the terminal blank, direct contact between the stamping die and the ultra-smooth surface is effectively avoided, thereby avoiding scratches, indentations and other damages, and maintaining its excellent characteristics of low roughness (such as Ra≤0.025). In actual use of the product, the ball moves on the ultra-smooth surface. The lower roughness can greatly reduce friction, make the movement smoother, significantly reduce the jamming phenomenon, and effectively improve the mechanical properties and operation stability of the product. In step 200, the hydrocarbon cleaning solvent has a dual effect: on the one hand, it can efficiently clean the dirt on the surface of the metal terminal and restore the terminal surface to cleanliness; on the other hand, it cleverly utilizes the degumming and softening characteristics of the hydrogen cleaning solvent on the bonding surface of the protective film, so that the protective film can be smoothly removed from the first transition piece. The above scheme not only achieves effective cleaning of the metal terminal, but also removes obstacles for subsequent processing steps, greatly facilitates subsequent processing operations, and ensures the continuity and efficiency of the entire processing flow. In step 600, the first transition piece and the second transition piece are welded together so that the conductive piece and the contact terminal are tightly connected as one, thereby ensuring the accuracy of the relative positions of the components and the stability of the connection during the injection molding process, which helps to improve the overall quality and consistency of the product.

[0017] Preferably, the first outer frame is provided with a first positioning hole, the central support member is provided with a second positioning hole, and the second outer frame is provided with a third positioning member hole.

[0018] In the lens module base processing technology, the first positioning hole set on the first outer frame, the second positioning hole on the center support, and the third positioning hole on the second outer frame provide accurate positioning references for the parts during the processing. In each step of operation, such as stamping, welding, injection molding and other processes, with these positioning holes, the parts can be accurately placed and fixed on the corresponding equipment or mold to ensure the accuracy of the processing position. It helps to improve the matching accuracy between the various components and make the connection between the conductive parts and the contact terminals and other components more accurate and reliable.

[0019] Preferably, the second transition piece obtained in step 400 further includes a support seat connected to the inner side of the conductive piece; in step 600, the support seat supports the central support piece.

[0020] In the above technical solution, the support seat of the second transition piece obtained in step 400 supports the central support piece in step 600, thereby enhancing the structural stability and avoiding misalignment between parts during subsequent processing.

[0021] Preferably, the cutting in step 900 is divided into two steps:

[0022] Step 901, using a punch press to punch and cut the support seat and the central support member that are not covered by the base body;

[0023] Step 902: Use an automatic cutting machine to cut the second outer frame outside the lens module base.

[0024] In the above technical solution, the cutting is divided into the inner side and the outer side for separate processing. In step 901, the third positioning member hole on the outer second outer frame can be used for positioning, and the position of the support seat and the center support member that are not covered by the base body can be accurately determined by the punch press, which effectively ensures the accuracy of the internal structure cutting and avoids accidental damage to other key parts. In step 902, the product itself can be used for positioning support to cut the outer second outer frame, which not only improves the convenience of positioning, but also makes full use of the stability of the formed part of the product, making the cutting of the outer second outer frame more accurate and neat. Through this cutting order of first inside and then outside and reasonable use of positioning, not only the accuracy and efficiency of cutting are greatly improved, but also the problems of product deformation and dimensional deviation caused by inaccurate positioning or improper support are effectively reduced, and the quality consistency and appearance quality of the product are significantly improved.

[0025] Preferably, in step 100, the first outer frames of the plurality of first transition pieces are sequentially connected to form a transition assembly; in step 300, after the first outer frames are cut and removed, the central support pieces in the respective first transition pieces are separated into separate individuals.

[0026] In the above technical solution, in step 100, the first outer frames of multiple first transition pieces are connected in sequence to form a transition assembly. In step 200, when the first transition piece is placed in a hydrocarbon cleaning machine for cleaning, the transition assembly form facilitates the overall pick-up and placement operation. Compared with a single first transition piece, the operator can place multiple first transition pieces connected together to the corresponding position in the cleaning machine more quickly and stably, avoiding the time waste and operational errors that may be caused by picking up and placing one by one. Moreover, during the cleaning process, the assembly form is also conducive to maintaining the relative position stability between the first transition pieces, ensuring the consistency of the cleaning effect. After the cleaning is completed, it is also more efficient to remove the transition assembly, reducing the risk of collision damage to the components caused by multiple individual pick-ups. When it comes to step 300, the first outer frame is cut and removed, so that the central support pieces in each first transition piece are separated into separate individuals, creating ideal conditions for subsequent precise welding with the second transition piece. The separate central support piece can be positioned and connected with other components with higher precision, reducing the influence of positioning deviation that may be caused by the previous component structure, ensuring that the welding position of each contact terminal and the conductive piece is accurate, thereby improving the overall structural accuracy and connection stability of the product. The design of combining first and then separating adopted in this application fully adapts to the characteristics and needs of different processing stages, optimizes the entire processing flow, improves the efficiency and convenience of operations such as cleaning, ensures the quality of subsequent welding and final products, and effectively reduces the defective rate.

[0027] Preferably, in step 200, the temperature of the hydrocarbon cleaning solvent is between 38° and 42°, and the immersion time is between 160 seconds and 200 seconds.

[0028] In the above technical solution, the temperature of the hydrocarbon cleaning solvent is controlled between 38° and 42°. Within this temperature range, the chemical activity of the hydrocarbon cleaning solvent can reach a relatively ideal state, and its molecular movement is more active, which can more effectively react with the bonding surface of the protective film, accelerate the softening and dissolution process of the adhesive, and make the protective film easier to fall off from the first transition piece. At the same time, it will not cause adverse effects on the surface of the metal terminal or other components due to excessive temperature, such as thermal deformation, changes in material properties, etc. The immersion time of 160 seconds to 200 seconds provides sufficient time for the solvent and the adhesive to fully react, ensuring the thoroughness of the demolding. At the same time, under this temperature and time condition, the solvent can also effectively remove dirt on the surface of the metal terminal, including oil stains and impurities that may be contaminated during the stamping process, so that the surface of the metal terminal is restored to cleanliness.

[0029] Preferably, the hydrocarbon cleaning machine is provided with an ultrasonic generator for transmitting ultrasonic waves to the hydrocarbon cleaning solvent.

[0030] In the above technical solution, after the ultrasonic generator transmits ultrasonic waves to the hydrocarbon cleaning solvent, high-frequency oscillations are generated in the solvent. Such high-frequency oscillations can form a strong impact force and cavitation effect, greatly enhancing the cleaning ability. For the first transition piece, ultrasonic waves can cause the hydrocarbon cleaning solvent to penetrate deeper into the tiny gaps between the protective film and the surface of the metal terminal and the places where dirt is attached, so that the reaction between the solvent and the adhesive is more sufficient, accelerating the shedding process of the protective film, and more thoroughly removing the fine particles, oil stains and other dirt that are difficult to remove from the surface of the metal terminal.

[0031] Preferably, the injection molding in step 800 adopts an injection process.

[0032] In the above technical solution, injection molding uses an injection process that can accurately control parameters such as the injection volume, speed and pressure of the plastic. A stable injection speed helps the plastic to be evenly filled in the mold cavity, reducing internal bubbles, looseness and other defects that may be caused by uneven filling, thereby improving the structural integrity and density uniformity of the product.

[0033] Preferably, after step 900, the method further includes:

[0034] Step 1000: Place the lens module base into a designed fixture tray and clean it using an ultrasonic cleaner;

[0035] Step 1100: inspect the ultra-smooth surface using a microscope and remove defective products;

[0036] Step 1200: Use a vacuum packaging machine to vacuum pack the product and put it into an outer box.

[0037] In the above step 1000, the lens module base is loaded into the designed fixture tray and cleaned with an ultrasonic cleaning machine. The fixture tray can effectively position and fix the product to prevent damage caused by collision during the cleaning process. Ultrasonic cleaning uses the powerful impact force generated by high-frequency oscillation to deeply remove impurities such as tiny particles and oil stains remaining on the surface of the product, ensuring that the surface of the product is highly clean. This provides a good foundation for subsequent inspection and use, avoiding the impact of surface dirt on product performance or appearance. Step 1100 uses a microscope to carefully inspect the ultra-smooth surface. With the high magnification of the microscope, it can accurately detect defects such as fine scratches, pits, and roughness changes that may exist on the ultra-smooth surface. Step 1200 uses a vacuum packaging machine to vacuum pack the product and put it into an outer box. The vacuum packaging effectively isolates the product from contact with external air, moisture and pollutants, preventing the product from being damaged in performance or appearance due to oxidation, moisture or dust during storage and transportation. The outer box provides physical protection to prevent the product from being mechanically damaged by squeezing, collision, etc.

[0038] Preferably, the base body is made of LCPCM529BP; the contact terminal is made of SUS316L, and the roughness of the ultra-smooth surface is Ra≤0.025; and the conductive part is made of SUS316L.

[0039] In the above technical solution, the base body is made of LCPCM529BP material, which has good mechanical properties, such as high strength and rigidity, and can provide stable structural support for the entire lens module base, ensuring that the base is not easily deformed or damaged under various use environments. The contact terminals and conductive parts are made of SUS316L material. SUS316L has excellent corrosion resistance and can maintain good performance under complex environmental conditions, avoiding oxidation or chemical reactions with other substances that affect the stability of electrical connections. Its good conductivity ensures smooth transmission of current between components, reducing power loss and signal interference. The ultra-smooth surface of the exposed part of the contact terminal has a roughness of Ra≤0.025. This ultra-smooth surface property greatly reduces the friction coefficient. In practical applications, when in contact with other components (such as balls, etc.) and relative motion occurs, it can significantly reduce friction, improve the smoothness and accuracy of movement, reduce mechanical wear, and extend the service life of components, thereby improving the performance and durability of the entire lens module base, ensuring that the product always maintains a stable and efficient working state during long-term operation.

[0053] Step 200: placing the first transition piece 2 into a hydrocarbon cleaning solvent of a hydrocarbon cleaning machine for cleaning and film removal; the hydrocarbon cleaning machine is provided with an ultrasonic generator for transmitting ultrasonic waves to the hydrocarbon cleaning solvent;

[0054] Step 300: Use a cutting machine to cut and remove the first outer frame 21 on the first transition piece 2 after demolding. Figure 4 As shown;

[0056] Step 500: electroplating the surface of the second transition piece 3;

[0057] Step 600: The first transition piece 2 obtained in step 300 is welded to the second transition piece 3 obtained in step 500 to obtain an assembly 4, such as Figure 6 As shown, the conductive member 13 in the assembly 4 is welded to the contact terminal 12, and the support seat 32 supports the central support member 22; Step 700: Partially bend the second transition member 3 in the assembly 4 by using a punching machine to form a second terminal 131 at the bent position;

[0058] Step 800: using an injection molding machine to perform injection molding on the assembly 4 to obtain a base blank; the injection molding adopts an injection process;

[0059] Step 900: Cutting the waste material on the base blank to obtain a lens module base 1;

[0060] Step 1000: Place the lens module base 1 into a designed fixture tray and clean it using an ultrasonic cleaning machine;

[0061] Step 1100: inspect the ultra-smooth surface 121 using a microscope to remove defective products;

[0062] Step 1200: Use a vacuum packaging machine to vacuum pack the product and put it into an outer box.

[0063] In the above technical solution, the ultra-smooth surface 121 is prone to damage during the stamping process. In step 100, by performing film stamping on the terminal blank, direct contact between the stamping die and the ultra-smooth surface 121 is effectively avoided, thereby avoiding scratches, indentations and other damages, and maintaining its excellent characteristics of low roughness (such as Ra≤0.025). When the product is actually used, the ball moves on the ultra-smooth surface 121. The lower roughness can greatly reduce friction, make the movement smoother, significantly reduce the jamming phenomenon, and effectively improve the mechanical properties and operation stability of the product. In step 200, the hydrocarbon cleaning solvent has a dual effect: on the one hand, it can efficiently clean the dirt on the surface of the metal terminal and restore the terminal surface to cleanliness; on the other hand, it cleverly utilizes the degumming and softening characteristics of the hydrogen cleaning solvent on the bonding surface of the protective film, so that the protective film can be smoothly removed from the first transition piece 2. The above scheme not only realizes the effective cleaning of the metal terminal, but also removes obstacles for the subsequent processing steps, greatly facilitates the subsequent processing operations, and ensures the continuity and efficiency of the entire processing flow. After the ultrasonic generator transmits the ultrasonic wave to the hydrocarbon cleaning solvent, it will generate high-frequency oscillations in the solvent. This high-frequency oscillation can form a strong impact force and cavitation effect, greatly enhancing the cleaning ability. For the first transition piece 2, the ultrasonic wave can cause the hydrocarbon cleaning solvent to penetrate deeper into the tiny gap between the protective film and the surface of the metal terminal and the dirt attachment, so that the reaction between the solvent and the adhesive is more sufficient, accelerates the shedding process of the protective film, and more thoroughly removes the fine particles, oil stains and other dirt that are difficult to remove on the surface of the metal terminal. In step 600, the first transition piece 2 and the second transition piece 3 are welded together to tightly connect the conductive part 13 and the contact terminal 12 as a whole, ensuring the accuracy of the relative position of each component during the injection molding process and the stability of the connection, which helps to improve the overall quality and consistency of the product. In step 800, the injection molding adopts an injection process, which can accurately control the parameters such as the injection amount, speed and pressure of the plastic. A stable injection speed helps to evenly fill the plastic in the mold cavity, reducing internal bubbles, looseness and other defects that may be caused by uneven filling, thereby improving the structural integrity and density uniformity of the product. In the above step 1000, the lens module base 1 is placed in a designed fixture tray and cleaned with an ultrasonic cleaner. The fixture tray can effectively position and fix the product to prevent damage caused by collision during the cleaning process. Ultrasonic cleaning uses the powerful impact force generated by high-frequency oscillations to deeply remove tiny particles, oil stains and other impurities remaining on the surface of the product, ensuring that the surface of the product is highly clean. This provides a good foundation for subsequent inspection and use, and avoids affecting product performance or appearance due to surface dirt. Step 1100 uses a microscope to carefully inspect the ultra-smooth surface 121. With the high magnification of the microscope, it is possible to accurately detect fine scratches, pits, roughness changes and other defects that may exist on the ultra-smooth surface 121.Step 1200 uses a vacuum packaging machine to vacuum pack the product and then put it into an outer box. The vacuum packaging effectively isolates the product from the outside air, moisture and pollutants, preventing the product from being degraded or damaged in appearance due to oxidation, moisture or dust during storage and transportation. The outer box provides physical protection to prevent the product from being squeezed, collided or other mechanical damage.

[0064] Preferably, the first outer frame 21 is provided with a first positioning hole 211 , the central support member 22 is provided with a second positioning hole 221 , and the second outer frame 31 is provided with a third positioning member hole 311 .

[0065] In the processing technology of the lens module base 1, the first positioning hole 211 set on the first outer frame 21, the second positioning hole 221 on the central support 22, and the third positioning hole 311 on the second outer frame 31 provide accurate positioning references for the parts during the processing. In each step of operation, such as stamping, welding, injection molding and other processes, with these positioning holes, the parts can be accurately placed and fixed on the corresponding equipment or mold to ensure the accuracy of the processing position. It helps to improve the matching accuracy between the various components and make the connection between the conductive part 13 and the contact terminal 12 and other components more accurate and reliable.

[0066] Preferably, the cutting in step 900 is divided into two steps: step 901, using a punch press to punch and cut the support seat 32 and the central support member 22 not covered by the base body 11; step 902, using an automatic cutting machine to cut the second outer frame 31 outside the lens module base 1.

[0067] In the above technical solution, the cutting is divided into the inner side and the outer side for separate processing. In step 901, the third positioning member hole 311 on the outer second outer frame 31 can be used for positioning, and the positions of the support seat 32 and the center support member 22 that are not covered by the base body 11 can be accurately determined by the punch press, which effectively ensures the accuracy of the internal structure removal and avoids accidental damage to other key parts. In step 902, the product itself can be used for positioning support to cut the outer second outer frame 31, which not only improves the convenience of positioning, but also makes full use of the stability of the formed part of the product, making the cutting of the outer second outer frame 31 more accurate and neat. Through this cutting order of first inside and then outside and reasonable use of positioning, not only the precision and efficiency of cutting are greatly improved, but also the problems of product deformation and dimensional deviation caused by inaccurate positioning or improper support are effectively reduced, and the quality consistency and appearance quality of the product are significantly improved.

[0068] Preferably, in step 100, the first outer frames 21 of the plurality of first transition pieces 2 are sequentially connected to form a transition assembly; in step 300, after the first outer frames 21 are cut and removed, the central support pieces 22 in the respective first transition pieces 2 are separated into separate individuals.

[0069] In the above technical solution, in step 100, the first outer frames 21 of multiple first transition pieces 2 are connected in sequence to form a transition assembly. In step 200, when the first transition piece 2 is placed in a hydrocarbon cleaning machine for cleaning, the transition assembly form facilitates the overall pick-up and placement operation. Compared with a single first transition piece 2, the operator can place multiple first transition pieces 2 connected together to the corresponding positions in the cleaning machine more quickly and stably, avoiding the time waste and operational errors that may be caused by picking up and placing one by one. Moreover, during the cleaning process, the assembly form is also conducive to maintaining the relative position stability between the first transition pieces 2, ensuring the consistency of the cleaning effect. After cleaning, it is also more efficient to remove the transition assembly, reducing the risk of collision damage to the components caused by multiple individual pick-ups. When it comes to step 300, the first outer frame 21 is cut and removed, so that the central support piece 22 in each first transition piece 2 is separated into a separate individual, creating ideal conditions for the subsequent precise welding with the second transition piece 3. The separate central support member 22 can be positioned and connected with other components with higher precision, reducing the influence of positioning deviations that may be caused by the previous component structure, ensuring that the welding position of each contact terminal 12 and the conductive member 13 is accurate, thereby improving the overall structural accuracy and connection stability of the product. The design of combining first and then separating adopted in this application fully adapts to the characteristics and requirements of different processing stages, optimizes the entire processing flow, improves the efficiency and convenience of operations such as cleaning, and ensures the quality of subsequent welding and final products, effectively reducing the defective rate.

[0070] Specifically, in step 200, the temperature of the hydrocarbon cleaning solvent is between 38° and 42°, and the immersion time is between 160 seconds and 200 seconds. The preferred temperature of the hydrocarbon cleaning solvent is 40°, and the preferred immersion time is 180 seconds.

[0071] In the above technical solution, the temperature of the hydrocarbon cleaning solvent is controlled between 38° and 42°. Within this temperature range, the chemical activity of the hydrocarbon cleaning solvent can reach a relatively ideal state, and its molecular movement is more active, which can more effectively react with the bonding surface of the protective film, accelerate the softening and dissolving process of the adhesive, and make the protective film easier to fall off from the first transition piece 2. At the same time, it will not cause adverse effects on the surface of the metal terminal or other components due to excessive temperature, such as thermal deformation, changes in material properties, etc. The immersion time of 160 seconds to 200 seconds provides sufficient time for the solvent and the adhesive to fully react, ensuring the thoroughness of the demolding. At the same time, under this temperature and time condition, the solvent can also effectively remove dirt on the surface of the metal terminal, including oil stains and impurities that may be contaminated during the stamping process, so that the surface of the metal terminal is restored to cleanliness.
