Description

Technical Field

[0001] The utility model relates to the technical field of camera module manufacturing, in particular to a three-axis mounting device for 3D special-shaped auxiliary materials. Background Art

[0002] In the current camera module industry, modules with autofocus functionality require grounding of the motor's outer metal casing because they incorporate a motor. To effectively prevent static electricity from accumulating and impacting camera module performance, the metal casing and underlying PCB are typically wrapped with conductive materials such as conductive cloth or copper foil. This practice ensures a tight connection between the exposed copper grounding area on the PCB and the motor's metal casing, effectively dissipating any static electricity generated.

[0003] However, the application of these shaped conductive fabrics or copper foils presents a significant challenge: they often need to be applied flatly to the bottom of the PCB, and then manually pressed on the remaining three sides to ensure they are fully adhered to the camera module. This traditional method is not only inefficient and labor-intensive, but also difficult to ensure uniformity, adhesion, and consistent conductivity due to manual intervention, which can negatively impact product quality.

[0004] Therefore, it is necessary to develop a new three-axis placement device for 3D special-shaped auxiliary materials. Summary of the Invention

[0005] The purpose of the utility model is to provide a three-axis placement device for 3D special-shaped auxiliary materials, which can improve production efficiency.

[0006] The three-axis placement device for 3D special-shaped auxiliary materials described in the utility model includes:

[0007] A pressing head body, the pressing head body having a first surface and a second surface, wherein a first groove is formed on the first surface;

[0008] Three side pressing heads are respectively provided on three different sides of the first groove, and the shape of the space enclosed by the three side pressing heads is adapted to the outer contour of the camera module to be bonded, so as to ensure that the 3D special-shaped auxiliary material can be bonded to the camera module;

[0009] A positive pressure head is mounted on the pressure head body and can move in the vertical direction relative to the pressure head body. The positive pressure head is located in the spatial shape, and the lower end surface of the positive pressure head protrudes from the lower end surface of the side pressure head. The positive pressure head is provided with a vacuum hole;

[0010] The top surface of the supporting platform is provided with a second groove for avoiding the lens portion of the camera module to prevent damage to the lens or affect the attachment effect during the attachment process.

[0011] Optionally, the side pressure head is installed on one side surface of the pressure head body through a movable connecting mechanism, so that the side pressure head can move in the vertical direction relative to the corresponding side surface; and a first elastic member is provided between the side pressure head and the pressure head body to provide appropriate pressure when the side pressure head contacts and presses the camera module, and allow the side pressure head to automatically reset after the pressure is released.

[0012] Optionally, there are two first elastic members arranged between the side pressure head and the pressure head body, which are respectively located on both sides of the side pressure head to enhance the stability and reset effect of the side pressure head.

[0013] Optionally, the first elastic member is a spring, and the elastic force of the spring is used to realize the automatic reset and adjustment functions of the side pressure head.

[0014] Optionally, a second elastic member is provided between the positive pressure head and the pressure head body to provide appropriate pressure when the positive pressure head contacts and presses the camera module, and to allow the positive pressure head to automatically reset after the pressure is released.

[0015] Optionally, the second elastic member is a spring, and the elastic force of the spring is used to realize the automatic reset and adjustment functions of the positive pressure head.

[0016] Optionally, a first spring mounting groove is provided at the bottom of the positive pressure head, and a second spring mounting groove corresponding to the first spring mounting groove is provided on the pressure head body. The lower end of the second elastic member is supported within the first spring mounting groove, and the upper end of the second elastic member abuts against the second spring mounting groove. By cleverly embedding the second elastic member into the first and second spring mounting grooves, not only is the connection structure between the positive pressure head and the pressure head body simplified, but subsequent maintenance and replacement are also facilitated. If the second elastic member wears out or fails, it can be simply removed and replaced with a new one.

[0017] Optionally, the surface of the side pressure head that first contacts the camera module is provided with a guide chamfer, so that the side pressure head can slide smoothly into the contour of the camera module, reduce friction and damage, and protect the surface of the camera module from damage.

[0018] Optionally, a handle is further included, one end of which is fixedly mounted on the second surface of the press head body, so that the operator can hold and operate (or tighten the equipment) the entire device, thereby improving operating efficiency and convenience and making the attachment process easier and more efficient.

[0019] The utility model has the following advantages:

[0020] (1) Improved production efficiency: The utility model avoids the redundant step of manually pressing 3D special-shaped auxiliary materials in the traditional method by designing a three-axis attachment device. It can significantly shorten the production cycle and improve production efficiency.

[0023] (3) Reduced labor costs:

[0024] The traditional method requires a lot of manual participation, especially in the process of pressing 3D special-shaped auxiliary materials. However, the utility model replaces this part of manual operation with an automated device, greatly reducing labor costs.

[0025] (4) Enhanced conductivity and adhesion:

[0026] Thanks to the automated and precise attachment method, the conductivity and adhesion of 3D special-shaped auxiliary materials are better guaranteed. This helps to improve the anti-static performance of the product and enhance its reliability and stability.

[0027] (5) Improved yield and reduced costs:

[0028] Automated operations reduce errors and defective products caused by human factors, thereby improving product yields. At the same time, due to increased production efficiency and reduced labor costs, the cost per unit of product is also reduced, enhancing the company's competitiveness.

[0029] In summary, the utility model realizes the fully automated attachment of 3D special-shaped auxiliary materials by designing a three-axis placement device for 3D special-shaped auxiliary materials, significantly improves production efficiency, attachment consistency, conductivity and adhesion, and reduces labor costs and product costs.

[0039] The following describes the implementation of the technical solution of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. The present invention may also be implemented or applied through different specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0040] like Figures 1 to 5 As shown, a three-axis placement device for 3D special-shaped auxiliary materials includes a press head body 1, three side press heads 3, a positive press head 9, and a supporting platform 5. The press head body 1 has a first surface and a second surface, wherein a first groove 11 is formed on the first surface. The three side press heads 3 are respectively arranged on three different sides of the first groove 11, and the spatial shape enclosed by the three side press heads 3 is adapted to the outer contour of the camera module 7 to be bonded, so as to ensure that the 3D special-shaped auxiliary materials can be bonded to the camera module 7. The positive press head 9 is mounted on the press head body 1 and can move in the vertical direction relative to the press head body 1. The positive press head 9 is located in the spatial shape, and the lower end surface of the positive press head 9 protrudes from the lower end surface of the side press heads 3. The positive press head 9 is provided with a vacuum hole (not shown in the figure, for connecting to a vacuum device) for adsorbing the 3D special-shaped auxiliary material 8 and flatly bonding the 3D special-shaped auxiliary material 8 to the bottom surface of the PCB of the camera module 7 through the positive press head 9. A second groove 51 is formed on the top surface of the supporting platform 5 to avoid the lens portion of the camera module 7 so as to prevent damage to the lens or affect the attachment effect during the attachment process.

[0041] like Figure 2 As shown, in one possible embodiment, the side pressure head 3 is mounted on a side surface of the pressure head body 1 via a movable connection mechanism (such as a screw 6), allowing the side pressure head 3 to move perpendicularly relative to the corresponding side surface. A first elastic member 4 is provided between the side pressure head 3 and the pressure head body 1 to provide appropriate pressure when the side pressure head 3 contacts and presses the camera module 7, and to allow the side pressure head 3 to automatically reset after the pressure is released.

[0042] like Figure 2 As shown, in a possible embodiment, two first elastic members 4 are provided between the side pressure head 3 and the pressure head body 1 , respectively located on both sides of the side pressure head 3 , so as to enhance the stability and reset effect of the side pressure head 3 .

[0043] like Figure 2 As shown, in a possible embodiment, the first elastic member 4 is a spring, and the elastic force of the spring is used to realize the automatic reset and adjustment functions of the side pressure head 3.

[0044] like Figures 1 to 5 As shown, in one possible embodiment, a second elastic member 10 is disposed between the positive pressure head 9 and the pressure head body 1. This provides appropriate pressure when the positive pressure head 9 contacts and compresses the camera module 7, and allows the positive pressure head 9 to automatically reset after the pressure is released. As an example, the second elastic member 10 is a spring. The spring's elastic force is utilized to achieve the automatic reset and adjustment functions of the positive pressure head.

[0045] like Figures 3 to 5 As shown, in one possible embodiment, a first spring mounting groove 91 is provided at the bottom of the positive pressure head 9, and a second spring mounting groove 12 corresponding to the first spring mounting groove 91 is provided on the pressure head body 1. The lower end of the second elastic member 10 is supported in the first spring mounting groove 91, and the upper end of the second elastic member 10 is tightly abutted in the second spring mounting groove 12. By cleverly embedding the second elastic member 10 into the first spring mounting groove 91 and the second spring mounting groove 12, not only is the connection structure between the positive pressure head 9 and the pressure head body 1 simplified, but subsequent maintenance and replacement work is also facilitated. When the second elastic member 10 wears out or fails, it can be simply disassembled and replaced with a new second elastic member 10.

[0046] like Figure 2 As shown, in a possible embodiment, the surface where the side pressure head 3 first contacts the camera module 7 is provided with a guide chamfer 31, so that the side pressure head 3 can smoothly slide into the edge of the camera module 7 (i.e., the side of the motor iron shell of the camera module), thereby reducing friction and damage and protecting the surface of the camera module 7 from damage.

[0047] As 1 to Figure 5As shown, in a possible embodiment, a three-axis placement device for 3D special-shaped auxiliary materials also includes a handle 2, one end of which is fixedly mounted on the second surface of the press head body 1, so that the operator can hold and operate the entire device (or the equipment fixture can clamp the entire device), thereby improving the operating efficiency and convenience, and making the attachment process easier and more efficient.

[0048] like Figure 3 and Figure 4 As shown, the steps for attaching 3D special-shaped auxiliary material 8 to the camera module are as follows:

[0049] First, a vacuum device (not shown in the figure) is connected to the vacuum hole on the positive pressure head 9 ; the vacuum device is operated to allow the positive pressure head 9 to absorb the 3D special-shaped auxiliary material 8 .

[0050] Next, align the positive pressure head 9 with the bottom surface of the camera module 7, and move the pressure head body 1 downward to make the 3D special-shaped auxiliary material 8 (special-shaped conductive cloth or conductive copper foil) flat on the bottom surface of the PCB of the camera module 7. The effect after flat bonding is shown in the figure. Figure 6 .

[0051] Then, continue to press down the pressure head body 1, and guide and attach the three sides of the 3D special-shaped auxiliary material 8 through the three side pressure heads 3. The effect after side attachment is shown in FIG. Figure 7 .

[0052] By using this three-axis placement device for 3D special-shaped auxiliary materials in production operations, the accuracy and efficiency of 3D special-shaped auxiliary material attachment are significantly improved, and various problems existing in traditional attachment methods are effectively avoided. At the same time, this three-axis placement device for 3D special-shaped auxiliary materials has a simple structure, convenient operation, and low maintenance costs, bringing significant economic benefits and competitive advantages to smartphone manufacturers.

[0053] In the embodiment of the present application, the pressure head body 1, the positive pressure head 9 and the side pressure head 3 are all made of stainless steel.

[0054] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered equivalent replacement methods and are included in the scope of protection of the present invention.
