Description

Technical Field

[0001] The present invention relates to the technical field of dispensing machines, and in particular to a precision dispensing machine for camera modules. Background Art

[0002] With the increasing popularity of electronic products and the continuous progress of technology, as one of the core components of electronic devices, the quality and performance requirements of camera modules are also increasing day by day. A camera module consists of multiple precision components, such as lenses, CMOS or CCD integrated circuits, infrared filters, etc. The fixation and sealing of these components are crucial for the stability and service life of the module. To improve the production efficiency and product quality of camera modules, precision dispensing machines have emerged.

[0003] For example, in the patent with the prior art publication number CN215612841U, this utility model relates to the technical field of dispensing machines, and in particular to a multi-station automatic dispensing machine for camera modules, including a base. One side of the base is fixedly connected with a support frame, and one side of the support frame is fixedly connected with a reduction motor. The advantages of this utility model are as follows: Through four dispensing components, the dispensing work can be carried out on the camera modules on four turntables simultaneously, and by starting the reduction motor, the four dispensing components can be rotated above the next turntable, and then the dispensing work can be carried out on the camera modules on the four turntables again.

[0004] However, it is found during the use of this dispensing machine that it is not convenient to use different glues for dispensing and processing camera modules according to processing requirements, which increases the limitations in use. Moreover, this dispensing machine is not convenient for controlling and adjusting the temperature of the glue, and the temperature of the glue is easily affected by the external environment and the viscosity changes, thereby affecting the dispensing quality. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a precision dispensing machine for camera modules that is convenient for dispensing different positions of the camera module, improves the convenience of using different glues for different processing requirements, is convenient for maintaining the appropriate viscosity and flow rate of the glue, and improves the dispensing quality.

[0006] A precision dispensing machine for a camera module of the present invention includes a base and a bracket, and the bracket is installed on the outer side wall of the base; it further includes a driving device, a supply device, a moving device, two dispensing guns, two delivery boxes, two sealing sleeves, two connecting pipes and two delivery pipes. The two dispensing guns are slidably installed on the bracket up and down through the driving device. The two delivery boxes are respectively installed on the outer side wall of the bracket. The two sealing sleeves are respectively arranged inside the two delivery boxes. The two connecting pipes are respectively communicated and arranged at the tops of the two dispensing guns. The upper parts of the two connecting pipes respectively slide into the interiors of the two sealing sleeves. Inlets are arranged on the upper parts of the two connecting pipes. The two delivery boxes are communicated with the supply device through the two delivery pipes. The supply device is used for delivering different glues into the two delivery boxes, and the supply device is used for controlling the temperature of the glue. The moving device is arranged on the base, and the moving device is used for moving and adjusting the camera module; the camera module to be dispensed is moved to the lower part of one of the dispensing guns through the moving device, and then one of the dispensing guns is driven to move downward through the driving device. After the dispensing gun moves downward, it drives the connecting pipe to move downward out of the sealing sleeve, so that the inlet of the connecting pipe communicates with the inside of the delivery box. Since the supply device delivers the glue into the delivery box through the delivery pipe, the glue in the delivery box is delivered into the dispensing gun through the connecting pipe, and then the dispensing gun that has moved downward dispenses the camera module. Through the different degrees of movement and adjustment of the camera module by the moving device, the camera module is dispensed at different positions. By switching the other dispensing gun to move downward through the driving device, it is convenient for the other dispensing gun to apply another kind of glue to the camera module.

[0007] Preferably, the supply device includes a temperature control device, two storage tanks, two glue addition valves, a box body, two hollow metal balls, two metal rods, multiple fins, and multiple heat conduction rods. The two storage tanks are connected to an external pressurization device. The two glue addition valves are respectively connected to the two storage tanks. The box body is installed on the tops of the two storage tanks. There is a heat-conducting liquid in the box body. The two hollow metal balls are respectively arranged inside the two storage tanks. The bottoms of the two metal rods are respectively connected to the two hollow metal balls. The upper parts of the two metal rods slide into the box body. Multiple fins are arranged on the upper parts of the two metal rods. Multiple heat conduction rods are respectively arranged on the two hollow metal balls. A temperature control device is arranged on the box body. The temperature control device is used to keep the heat-conducting liquid in the box body at a constant temperature. Two conveying pipes are respectively connected to the two storage tanks. Two different glues are respectively stored inside the two storage tanks. The two storage tanks are pressurized by an external pressurization device, so that the pressure squeezes and conveys the glue through the two conveying pipes into the two conveying boxes. When the connecting pipe moves upward, the opening of the connecting pipe extends into the sealing sleeve, so that the glue cannot be discharged through the glue spraying gun. When the connecting pipe moves downward, the opening of the connecting pipe communicates with the inside of the conveying box, so that the glue in the conveying box is discharged outward through the glue spraying gun. The temperature of the heat-conducting liquid is kept constant by the temperature control device, so that the heat-conducting liquid adjusts the temperature of the hollow metal balls through multiple fins and two metal rods. The hollow metal balls float in the upper part of the glue in the two storage tanks, so that the two hollow metal balls adjust the temperature of the glue. At the same time, with the cooperation of multiple heat conduction rods for heat conduction, the heat uniformity of the glue is improved. The two hollow metal balls move up and down with the liquid level height of the glue in the two storage tanks. The storage amount of the glue is measured by the position movement of the two hollow metal balls, which improves the convenience of liquid level induction and the versatility.

[0008] Preferably, the temperature control device includes a constant temperature box, a semiconductor refrigeration plate, a submersible pump, a first three-way pipe, two first valves, and two return pipes. The constant temperature box is installed on the top of the box body. The semiconductor refrigeration plate is installed in the middle of the inner side wall of the constant temperature box. The submersible pump is arranged in the box body. The bottom end of the first three-way pipe is connected to the submersible pump. The two output ends of the first three-way pipe are respectively connected to the inside of the constant temperature box on both sides of the semiconductor refrigeration plate. The two first valves are respectively connected to the two output ends of the first three-way pipe. The two sides of the constant temperature box are connected to the box body through two return pipes. After the submersible pump is started, the heat-conducting liquid in the box body is conveyed to the inside of the constant temperature box through the first three-way pipe. Then, the heat-conducting liquid in the constant temperature box flows back to the box body through the return pipe. When it is necessary to heat the glue, the heat-conducting liquid is conveyed at the heat dissipation end of the semiconductor refrigeration plate, so that the heat-conducting liquid is heated in the constant temperature box. On the contrary, the heat-conducting liquid is cooled, so as to improve the control effect of glue temperature adjustment.

[0009] Preferably, the mobile device includes an adjusting device, a first electric rotating table, a vacuum table, a second electric rotating table, a frame, a first clamp, and a second clamp. The first electric rotating table is installed on the rotating end of the second electric rotating table, and the vacuum table is installed on the rotating end of the first electric rotating table.

The first electric rotating table drives the vacuum table to rotate, so that the vacuum table drives the camera module to rotate.

By cooperating with the adjusting device to move the position of the second electric rotating table, the convenience of dispensing glue at different position points of the camera module and using different glue spraying guns for dispensing glue is improved. Another camera module to be assembled is clamped and fixed by the second clamp. After the glue dispensing of the camera module on the vacuum table is completed, the second electric rotating table drives the first electric rotating table to rotate, so that the camera module on the vacuum table faces the camera module on the second clamp. Then, by moving the vacuum table close to the frame, the two camera modules are adhesively assembled. After that, the assembled camera module is clamped and fixed by the first clamp, improving the convenience of automatic assembly after automatic glue dispensing of the camera module.

[0010] Preferably, it further includes two groups of magnetic rods, two groups of magnetic blocks, and two groups of contact sensors. The two groups of magnetic rods are respectively installed at the tops of the two groups of metal rods. The two groups of magnetic blocks are both slidably installed on the outer side wall of the box body up and down. The two groups of magnetic blocks are magnetically adsorbed to the two groups of magnetic rods. The two groups of contact sensors are both installed on the outer side wall of the box body. The two groups of hollow metal balls drive the two groups of magnetic rods to move downward as the glue liquid level drops. The two groups of magnetic rods drive the two groups of magnetic blocks to move downward by magnetic force. When the magnetic blocks contact the contact sensors, the contact sensors are triggered to give a liquid level alarm, so as to facilitate adding glue to the two storage tanks in time.

[0012] Preferably, the driving device includes a sleeve and two connecting arms. The sleeve is rotatably mounted on the outer wall of the bracket by a driving motor. The two connecting arms are respectively slidably mounted on both sides of the sleeve, and the ends of the two connecting arms are respectively rotatably connected to the outer walls of the two glue guns. The driving motor drives the sleeve to rotate and swing, so that the sleeve drives the two glue guns to move up and down oppositely through the two connecting arms, thereby facilitating the interchangeable use of the two glue guns to discharge different glues respectively, and improving the convenience of dispensing different glues.

[0013] Preferably, it further includes an air suction pump, a second three-way pipe and a second valve. The air suction pump is internally connected to the two storage tanks through the second three-way pipe, and the second valve is connected to the second three-way pipe. When the dispenser needs to stop, the air suction pump sucks air into the two storage tanks, so that the two storage tanks extract the glue in the two conveying pipes, the two conveying boxes and the two glue guns, avoiding the situation of glue solidification and blockage.

[0014] Preferably, it further includes two laser rangefinders, which are respectively mounted on the outer walls of the two glue guns. By measuring the position between the camera module and the glue gun through the two laser rangefinders, it is convenient to control the lifting height of the vacuum table and improve the accuracy of dispensing control of the glue gun on the camera module.

[0015] Preferably, a temperature sensor is provided on the box body, improving the accuracy and convenience of temperature control and adjustment of the heat-conducting liquid.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The camera module to be dispensed is moved to below one of the glue guns by the moving device. Then, one of the glue guns is driven to move downward by the driving device. After the glue gun moves downward, the connecting pipe is driven to move downward out of the sealing sleeve, so that the inlet of the connecting pipe communicates with the inside of the conveying box. Since the supply device transports the glue to the conveying box through the conveying pipe, the glue in the conveying box is transported to the glue gun through the connecting pipe, and then the glue gun after moving downward dispenses the camera module. By adjusting the movement of the camera module to different degrees by the moving device, the camera module can be dispensed at different positions. By switching the other glue gun to move downward by the driving device, it is convenient for the other glue gun to apply another kind of glue to the camera module, improving the convenience of dispensing for different processing requirements. By adjusting the temperature of the glue by the supply device, the appropriate viscosity and flow rate of the glue are maintained, improving the quality of dispensing.
