Description

Technical Field

[0001] This utility model relates to the field of DC-DC converter technology, and specifically to an automatic chip mounting device. Background Technology

[0002] A DC-DC converter is an electronic circuit or device that converts DC power from one voltage level to another. It uses a controllable switch to perform high-frequency switching, storing the input electrical energy in an inductor or capacitor. When the switch is opened, the electrical energy is released to the load. In the production process of DC-DC converters, surface mount devices are used to mount electrical components onto the circuit printed circuit board.

[0003] Currently, when using surface mount technology (SMT) devices, there is a lack of auxiliary pre-correction mechanisms. Typically, before SMT processing of DC-DC converter circuit printed circuit boards, they need to be transported via conveyor belts or other conveyor mechanisms. However, during actual transport, positional deviations can easily occur, affecting the accuracy and continuity of SMT processing and increasing processing time. Therefore, an automatic SMT device is proposed to incorporate an auxiliary pre-correction mechanism. Utilizing sliding, lifting, and flipping methods, auxiliary correction is performed simultaneously during the feeding process. This not only improves the accuracy of SMT processing but also enhances the efficiency of DC-DC converter circuit printed circuit board SMT processing, thereby improving the overall performance. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an automatic patching device that can simultaneously perform auxiliary correction processing during the feeding process, thereby improving the performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is an automatic patching device, including a frame, a feeding assembly and a patching assembly. The feeding assembly is provided on the top of the frame, and a support frame is provided on the top of the frame behind the feeding assembly. The patching assembly is provided on the top of the support frame.

[0006] The feeding assembly includes a lifting platform, a positioning plate is rotatably connected to the outer side of the lifting platform, and a rotating shaft is bolted to both sides of the positioning plate. A limit plate is bolted to the top of the lifting platform located on one side of the positioning plate. Elastic pads are adhered to the surfaces of the positioning plate and the limit plate.

[0007] By adopting the above technical solution, an auxiliary pre-correction mechanism can be added. By using sliding, lifting, and flipping methods, the placement position of the DC-DC converter circuit printed circuit board can be automatically corrected during the feeding process, thereby improving the accuracy of the placement process.

[0008] Specifically, the patch assembly includes a rotating frame, and a support frame is mounted on the rotating frame via bearings. The bottom of the rotating frame is bolted to a mounting frame, and the bottom of the mounting frame is bolted to suction trays at equal intervals. The top of the mounting frame is bolted to a discharge hose, which is connected to the suction trays. The top of the support frame is bolted to a stepper motor, which is connected to the rotating frame via a drive shaft.

[0009] By adopting the above technical solution, continuous feeding of the patch can be achieved by rotation, while the negative pressure generated by suction can be used to assist unloading, thereby improving the continuity of the device's operation.

[0010] Specifically, the outer side of the lifting platform has a notch, and the positioning plate is rotatably connected to the notch via a rotating shaft. A rotary motor is bolted to one side of the lifting platform, and the rotary motor is connected to the rotating shaft via a drive shaft. An electric push rod is bolted to the top of the frame, and the output end of the electric push rod is bolted to the lifting platform.

[0011] By adopting the above technical solution, the notch facilitates the rotation of the positioning plate to connect with the lifting platform, the rotary motor facilitates the driving of the positioning plate to flip for pre-correction, and the electric push rod facilitates the control and adjustment of the height of the feeding component.

[0012] The beneficial effects of this utility model are:

[0013] (1) The automatic chip mounting device described in this utility model can add an auxiliary pre-correction mechanism by setting a frame, lifting platform, positioning plate, rotating shaft, limiting plate and elastic pad. By using sliding, lifting and flipping, the chip mounting position of the DC-DC converter circuit printed circuit board is automatically corrected during the feeding process. This not only improves the accuracy of chip mounting, but also helps to improve chip mounting efficiency and shorten processing time.

[0014] (2) The automatic patching device described in this utility model, through the setting of a rotating frame, mounting frame, unloading hose and stepper motor, can automatically complete the auxiliary unloading by means of rotation and suction. It can not only improve the continuity of patching processing, but also realize the auxiliary recycling of workpieces, thereby improving the practicality of the device. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] To facilitate simultaneous auxiliary correction during the feeding process, thereby improving the usage effect, such as... Figure 1-3 As shown, the automatic patching device of this utility model includes a frame 1, a feeding assembly 2 and a patching assembly 4. The feeding assembly 2 is provided on the top of the frame 1, and a support frame 3 is provided on the back of the feeding assembly 2 on the top of the frame 1.

[0023] The feeding assembly 2 includes a lifting platform 201, a positioning plate 202 is rotatably connected to the outer side of the lifting platform 201, and a rotating shaft 203 is bolted to both sides of the positioning plate 202. A limiting plate 204 is bolted to the top of the lifting platform 201 located on one side of the positioning plate 202. An elastic pad 205 is adhered to the surface of both the positioning plate 202 and the limiting plate 204.

[0024] In use, the frame 1, lifting platform 201, rotating shaft 203, limiting plate 204 and elastic pad 205 can be used to add an auxiliary pre-correction mechanism. By sliding, lifting and flipping, the chip position of the DC-DC converter circuit printed circuit board is automatically corrected during the feeding process, thereby improving the accuracy of chip mounting.

[0025] To improve the continuity of device use, for example, such as Figure 1 , Figure 3As shown, this utility model also includes the patch assembly 4, which includes a rotating frame 401, and the rotating frame 401 is mounted on the support frame 3 via bearings. The bottom of the rotating frame 401 is connected to the mounting frame 402 by bolts. The bottom of the mounting frame 402 is connected to the suction plate 403 at equal intervals by bolts. The top of the mounting frame 402 is connected to the unloading hose 404 by bolts, and the unloading hose 404 communicates with the suction plate 403. The top of the support frame 3 is connected to the stepper motor 301 by bolts, and the stepper motor 301 is connected to the rotating frame 401 via a drive shaft.

[0026] In use, the rotating frame 401, mounting frame 402, suction plate 403, unloading hose 404 and stepper motor 301 can achieve continuous feeding of the patch by rotation, and at the same time use the negative pressure generated by suction to assist unloading, thereby improving the continuity of the device's use.

[0027] For example, such as Figure 1 , 2 As shown, the present invention also includes a notch 206 on the outer side of the lifting platform 201, and a positioning plate 202 rotatably connected to the notch 206 via a rotating shaft 203. A rotary motor 207 is bolted to one side of the lifting platform 201, and the rotary motor 207 is connected to the rotating shaft 203 via a drive shaft. An electric push rod 6 is bolted to the top of the frame 1, and the output end of the electric push rod 6 is bolted to the lifting platform 201.

[0028] In use, the notch 206 facilitates the rotation of the positioning plate 202 to connect with the lifting platform 201, the rotary motor 207 facilitates the driving of the positioning plate 202 to flip for pre-correction, and the electric push rod 6 facilitates the control and adjustment of the height of the feeding assembly 2.

[0029] For example, such as Figure 3 As shown, the present invention also includes a mounting bracket 405 at the bottom of the mounting frame 402, a mounting head 406 at the bottom of the mounting bracket 405, and a cylinder 407 connected to the top of the mounting frame 402 by bolts, and the output end of the cylinder 407 is connected to the mounting bracket 405 by bolts.

[0030] In use, by mounting bracket 405, placement head 406 and cylinder 407, it can pick up the chip and perform automatic chip placement processing.

[0031] For example, such as Figure 1 As shown, the present invention also includes a first conveyor belt 101 provided on one side of the top of the frame 1, a guide plate 102 being bolted to one side of the discharge end of the first conveyor belt 101, and a second conveyor belt 5 provided on the other side of the frame 1.

[0032] In use, the first conveyor belt 101 and the second conveyor belt 5 facilitate the automatic placement of the DC-DC converter circuit printed circuit board and the chip.

[0033] For example, such as Figure 4 As shown, the present invention also includes a ball groove 103 formed on the surface of the guide plate 102, and a ball ball 104 is rolled in the ball groove 103.

[0034] In use, the ball groove 103 and the ball 104 can reduce the friction generated during the material feeding process by utilizing rolling contact.

[0035] In use, the DC-DC converter circuit printed circuit board first slides through the first conveyor belt 101 and the guide plate 102 to one side of the lifting platform 201 limit plate 204. The electric push rod 6 is manually activated to drive the lifting platform 201 to move vertically upward. At the same time, the rotary motor 207 drives the rotating shaft 203 and the positioning plate 202 to rotate upward by 90°. The positioning plate 202 and the limit plate 204 are used to perform auxiliary limiting processing on the DC-DC converter circuit printed circuit board, and at the same time, the chip placement position is corrected to improve the accuracy and stability of chip placement processing.

[0036] While the DC-DC converter circuit printed circuit board is being loaded, the chip is conveyed to the bottom of the rotating frame 401 via the second conveyor belt 5. The cylinder 407 is manually activated to drive the placement head 406 to slide down to the top of the chip for pickup. At the same time, the stepper motor 301 drives the rotating frame 401 to rotate, moving the chip to the top of the DC-DC converter circuit printed circuit board. The placement head 406 is then driven down again by the cylinder 407 to perform automatic chip placement. After chip placement is completed, the stepper motor 301 drives the suction plate 403 to rotate to the top of the DC-DC converter circuit printed circuit board. The negative pressure generated by the air pump connected to the unloading hose 404 is used to lift the DC-DC converter circuit printed circuit board, which is then moved and unloaded by the rotation of the rotating frame 401. The overall structure is simple and easy to operate, making it more flexible and efficient, and also helps to improve chip placement efficiency.
