Description

Technical Field

[0001] This utility model relates to the field of chip mounter technology, and in particular to a dual-head chip mounter. Background Technology

[0002] Surface mount technology is a core assembly technology in the electronics manufacturing industry. As a key piece of equipment in the SMT production line, the core function of the pick-and-place machine is to accurately pick up micro-electronic components and place them onto the preset pad positions on carriers such as printed circuit boards and flexible substrates. This directly determines the assembly accuracy, reliability, and production efficiency of the finished electronic products.

[0003] Currently, most common pick-and-place machines on the market require two machines to complete the placement of components from small to large. Furthermore, these two machines require two separate computers with two independent operating systems. This makes the connection, operation, and use of the machines quite complicated. It takes two machines to complete the universal placement of components from small to large, which is time-consuming, labor-intensive, and affects the efficiency of the placement process, resulting in poor overall practicality. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: A dual-head chip mounter includes a machine body, a protective cover mounted on the top of the machine body, and a worktable fixed on the upper surface of the machine body; The workbench surface is equipped with a board feeding track, on which a first gantry placement head is slidably mounted. A second gantry placement head is distributed on one side of the first gantry placement head. A guide rail is distributed at the other end of the board feeding track, and a first linear motor is installed at the bottom of one end of the guide rail. A second linear motor is fixed to the back of the first gantry placement head, and a downward pressure motor is distributed above the second linear motor. The output end of the downward pressure motor is connected to a transmission structure. A filter is provided on the front surface of the first gantry placement head. The bottom of the filter is connected to a rotary joint, and the bottom of the rotary joint is connected to a spline, with a mounting head installed at the bottom of the spline.

[0005] Preferably, the transmission structure includes a synchronous pulley and upper and lower belts. The synchronous pulley is connected to the output end of the lower motor, and the upper and lower belts are sleeved on the outer surface of the synchronous pulley.

[0006] Preferably, a camera body is fixedly mounted at the bottom front end of the first gantry mounting head, and a lens is mounted at the bottom of the camera body, with a coaxial light source distributed below the lens.

[0007] Preferably, a rotary motor is distributed at one end of the coaxial light source, and a solenoid valve vacuum integrated system is installed on one side of the top of the first gantry mounting head.

[0008] Preferably, a lower vision light source and a vision camera are distributed at the front end of the feeding track, and a nozzle exchange magazine is distributed on one side of the lower vision light source and the vision camera.

[0009] Preferably, the outer surface of the synchronous pulley has multiple teeth arranged in a circular array along the center point, and the synchronous pulley is connected to the teeth arranged on the inner sidewalls of the upper and lower belts through these teeth.

[0010] Preferably, the filters are equidistantly distributed along the front surfaces of the first gantry mounting head and the second gantry mounting head.

[0011] Preferably, the surfaces of the lower vision light source and the vision camera are provided with transparent glass plates, and multiple independent cameras are equidistantly arranged in the inner cavities of the lower vision light source and the vision camera.

[0012] As an improvement to the above technical solution, by setting up a structure in which 12 sets of placement heads can be moved independently by the X-axis and Y-axis linear motors of the first gantry placement head, 8 sets of placement heads can be moved independently by the X-axis and Y-axis linear motors of the second gantry placement head, and other linear motors, it is possible to achieve a combination of different numbers of heads for multiple modules on one machine, solving the problem that the existing one-machine-one-system left and right gantry structure module equipment cannot complete the combination of multiple heads plus fewer heads on one machine-one-system.

[0013] The beneficial effects of this utility model are: 1. This utility model, through its structure including a first gantry mounting head, a second gantry mounting head, and a linear motor, facilitates the subsequent combination of two different module structures, achieving multi-module integration in a single machine. By combining the number of heads, the system can overcome the limitations of operating 12 heads plus 8 heads on the left and right sides of the device. This solves the problem that existing one-machine-one-system left and right gantry structure module equipment cannot complete the combination of multiple heads plus fewer heads in one machine-one-system. It enables one device to independently complete the placement of components from small to large, making the overall practicality higher. Attached Figure Description

Detailed Implementation

[0016] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0017] Referring to Figures 1-7, a dual-head chip mounter includes a machine body 1, a protective cover 2 installed on the top of the machine body 1, and a worktable 3 fixed on the upper surface of the machine body 1. The worktable 3 is made of marble, and a feeder is provided at the front end of the worktable 3. A board feeding track 4 is mounted on the surface of the workbench 3, and a first gantry placement head 5 is slidably mounted on the board feeding track 4. A second gantry placement head 6 is distributed on one side of the first gantry placement head 5. The first gantry placement head 5 is equipped with 12 sets of placement heads, while the second gantry placement head 6 is equipped with 8 sets of placement heads. A guide rail 7 is distributed at the other end of the board feeding track 4, and a first linear motor 8 is installed at the bottom of one end of the guide rail 7. A second linear motor 9 is fixed to the back of the first gantry placement head 5, and a pressure motor 10 is distributed above the second linear motor 9. The output end of the pressure motor 10 is connected to a transmission structure. A filter 13 is installed on the front surface of the first gantry placement head 5. The filter 13 can filter impurities, solder paste, etc., to avoid impurities contaminating the placement process and preventing problems such as chip misalignment, nozzle blockage, and solenoid valve system blockage caused by impurities, ensuring flat and accurate labeling. A rotary joint 14 is connected to the bottom of the device, and a spline 15 is connected to the bottom of the rotary joint 14. A rotation angle motor is connected to the side of the spline 15, and a mounting head 16 is installed at the bottom of the spline 15. In this embodiment, during use, the board material to be mounted is placed on the board feeding track 4. The board material is transported to the bottom of the first gantry mounting head 5 by the board feeding track 4. Then, the first linear motor 8 drives the guide rail 7 to move, and the movement of the guide rail 7 adjusts the position of the first gantry mounting head 5. With the movement of the first gantry mounting head 5, the mounting head 16 can easily pick up the components. After picking up, the first gantry mounting head 5 resets, driving the mounting head 16 to move. The mounting head 16 then moves to the designated position under the action of the first gantry mounting head 5. Then, the pressing motor 10 operates, causing the transmission structure to move accordingly. Under the action of the transmission structure, the mounting head 16 presses down on the components, thus pressing the components onto the board material, achieving the purpose of mounting. Meanwhile, when the second linear motor 9 operates, it causes the first gantry mounting head 5 to move along the transverse guide rail 7. The horizontal position is adjusted to further adjust the position of the placement head 16. After placement, the board is transported to the bottom of the second gantry placement head 6 by the board feeding track 4. Then, the structure set on the second gantry placement head 6 is used to pick up and re-place components of another size. Thus, by using the cooperation of the two gantry heads, one machine can complete the general independent placement of components from small to large. It is worth noting that since the number of placement heads 16 set at the bottom of the first gantry placement head 5 and the second gantry placement head 6 are twelve and eight respectively, and the two gantry modules are controlled by the same system, it is possible to achieve independent placement of different numbers of placement heads 16 on the left and right. One system operates the machine with 12 heads on the left and 8 heads on the right, achieving the purpose of simple operation. 12 heads are used for placing small components, and 8 heads are used for placing large components, which is more flexible. When the placement head 16 picks up the component, the filter 13 is used. It can perform simple filtration and impurity removal on the circulating air to prevent dust particles in the air from causing structural damage, while the spline 15 provided with the rotary joint 14 is used to enable quick installation and removal of the filter 13.

[0018] The transmission structure of this utility model includes a synchronous pulley 11 and upper and lower belts 12. The synchronous pulley 11 is connected to the output end of the lower motor 10, and the upper and lower belts 12 are sleeved on the outer surface of the synchronous pulley 11. In this embodiment, as the down-pressing motor 10 drives the synchronous pulley 11 to rotate, the upper and lower belts 12 sleeved on its outer surface will rotate accordingly under the rotation of the synchronous pulley 11, thereby facilitating the subsequent rotation of the other synchronous pulley 11 by using the movement of the upper and lower belts 12.

[0019] In this utility model, a camera body 17 is fixedly provided at the bottom front end of the first gantry mounting head 5, and a lens 18 is installed at the bottom of the camera body 17, with a coaxial light source 19 distributed below the lens 18. In this embodiment, during use, the camera body 17 can identify reference points on the PCB board, determine the accurate position of the board in the equipment, and capture images of components picked up by the placement head 16 to determine their model, orientation, and offset, feeding this information back to the control system to correct the placement position. Furthermore, the lens 18 can switch magnification according to the size of the components during use, ensuring that even minute details are identifiable. When illuminating components, the use of the coaxial light source 19 allows light to shine along the axis of the lens 18, reducing reflections on the component surface and clearly distinguishing the component outline, pin spacing, and background, thus helping the camera body 17 accurately identify feature points.

[0020] In this utility model, a rotary motor 20 is distributed at one end of the coaxial light source 19, and an electromagnetic valve vacuum integrated system 21 is installed on one side of the top of the first gantry mounting head 5; In this embodiment, the operation of the rotary motor 20 can facilitate the rotation of the mounting head 16, thereby calibrating the offset caused by vibration when the mounting head 16 picks up the material, thus preventing positional offset during the subsequent mounting process and affecting the accuracy of the mounting.

[0021] In this utility model, a lower vision light source and a vision camera 22 are distributed at the front end of the feeding track 4, and a suction nozzle exchange chamber 23 is distributed on one side of the lower vision light source and the vision camera 22. In this embodiment, during use, the mounting head 16 picks up the material placed on the nozzle exchange magazine 23. The picked-up material then passes through the lower vision light source and vision camera 22, and the material is identified by multiple independent cameras set inside the lower vision light source and vision camera 22.

[0022] In this utility model, the outer surface of the synchronous pulley 11 has multiple teeth arranged in a circular array along the center point, and the synchronous pulley 11 is connected to the teeth arranged on the inner sidewall of the upper and lower belts 12 through these teeth; In this embodiment, since the synchronous pulley 11 is meshed with the upper and lower belts 12, the movement of the synchronous pulley 11 can facilitate the subsequent movement of the upper and lower belts 12, and the movement of the upper and lower belts 12 can be used to realize the movement of the other synchronous pulley 11.

[0023] In this invention, the filter 13 is equidistantly distributed along the front surfaces of the first gantry mounting head 5 and the second gantry mounting head 6; In this embodiment, since multiple filters 13 are equally spaced, the air being transported can be effectively filtered and impurities removed by using the multiple filters 13.

[0024] In this invention, the surfaces of the lower vision light source and the vision camera 22 are provided with transparent glass plates, and the lower vision... The inner cavity of the light source and the vision camera 22 is equidistantly equipped with a corresponding number of independent cameras corresponding to the number of mounting heads 16; In this embodiment, the use of multiple independent cameras set in the cavity of the lower vision light source and vision camera 22 facilitates better subsequent visual positioning processing in conjunction with structures such as the coaxial light source 19.

[0025] The operation and working principle of this dual-head placement machine are as follows: During operation, the board to be placed is placed on the feeding track 4. The feeding track 4 transports the board to the bottom of the first gantry placement head 5. Then, the first linear motor 8 drives the guide rail 7 to move, and the movement of the guide rail 7 adjusts the position of the first gantry placement head 5. As the first gantry placement head 5 moves, the placement head 16 facilitates subsequent component pickup. Components pass through a lower vision light source and a vision camera 22. Multiple independent cameras within the lower vision light source and vision camera 22 identify and process the material. After pickup, the first gantry placement head 5 resets, driving the placement head 16 to move. The placement head 16 then moves to the designated position under the action of the first gantry placement head 5. Subsequently, the lower pressure motor 10 operates, causing the transmission structure to move accordingly. The movement of the transmission structure then moves the placement head 16... The first linear motor 9 drives the component to press down, thus pressing the component onto the board to achieve the purpose of placement. When the second linear motor 9 is working, it causes the first gantry placement head 5 to adjust its lateral position along the transverse guide rail 7, thereby further adjusting the position of the placement head 16. After placement, the board is transported to the bottom of the second gantry placement head 6 by the board feeding rail 4. Then, the structure set on the second gantry placement head 6 is used to pick up and relabel components of another size. By using the cooperation of the two gantry heads, one machine can complete the universal and independent placement of components from small to large. When the picked-up component is offset due to vibration or other factors, the operation of the rotary motor 20 can facilitate the subsequent rotation of the placement head 16. This allows for the calibration of the offset caused by vibration when the placement head 16 picks up the material, thereby preventing positional offset during the subsequent placement process and affecting the placement accuracy.

Those skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
