Description

Technical Field

[0001] This application relates to the technical field of electronic component chip mounting, and particularly to an electronic component chip mounting device. Background Art

[0002] A chip mounter is a machine composed of a frame, a PCB transfer mechanism and a support table, a chip head, a feeder, a sensor and other devices, which is used to accurately attach surface mount components to a printed circuit board (PCB) and is an essential key device in electronic production.

[0003] In the prior art, the circuit board is manually fixed on a bracket or a workbench. The operator manually rotates screws or adjusts clamps to ensure the stability of the circuit board. However, manually fixing the circuit board requires the operator to spend a lot of time and energy, increasing the labor cost and production cycle.

[0004] To solve the problem of fixing the circuit board, the prior art uses screws, clamps or other fixing devices, and the circuit board is manually fixed on a bracket or a workbench for processing. However, there are some problems in the process of manually fixing the circuit board, including insecure fixing, low efficiency and errors caused by human factors. Utility Model Content

[0005] The purpose of this application is to solve the disadvantage of insecure fixing in the prior art, and to propose an electronic component chip mounting device.

[0006] To achieve the above purpose, this application adopts the following technical solution: An electronic component chip mounting device, including a machine body, a cylinder is fixedly connected to the upper surface of the machine body, the output end of the cylinder is fixedly connected to a chip head, a support table is arranged below the chip head, the lower surface of the support table is fixedly connected to the machine body, a fixing device is arranged on the upper surface of the machine body, the fixing device includes four positioning blocks, the lower surfaces of the four positioning blocks are fixedly connected to the machine body, the four positioning blocks are evenly distributed on the upper surface of the machine body, one end of the machine body is fixedly connected to a support plate, a driving motor is arranged on the upper surface of the support plate, the output end of the driving motor is fixedly connected to a screw rod, the screw rod threadedly penetrates through two positioning blocks, a double-thread is arranged on the arc surface of the screw rod, two adjusting plates are threadedly connected to the arc surface of the screw rod, a lead screw is threadedly connected to the inner wall of the adjusting plate, the lead screw threadedly penetrates through the positioning block, a double-thread is arranged on the arc surface of the lead screw, a wheel disc is fixedly connected to one side of the screw rod and the lead screw close to the output end of the driving motor, and a belt is rotatably connected to the arc surfaces of the two wheel discs.

[0007] The effects achieved by the above components are as follows: When the driving motor is started, the driving motor drives the screw to rotate, and the rotation of the screw indirectly drives the lead screw to rotate. Since double-threaded threads are provided on their surfaces, the adjusting plate on the arc surface will move in the opposite direction until the circuit board is clamped and fixed.

[0008] Preferably, a chute is provided on the upper surface of the body, and a connecting column is slidably connected to the inner wall of the chute. The upper surface of the connecting column is fixedly connected to the adjusting plate.

[0009] The effects achieved by the above components are as follows: When the screw and the lead screw drive the adjusting plate to move towards the circuit board, the adjusting plate can slide along the chute under the support of the connecting column, which plays a role in limiting and supporting it.

[0010] Preferably, a protective cover is provided on the upper surface of the support plate.

[0011] The effects achieved by the above components are as follows: The driving motor can be protected from the influence and damage of the external environment, and at the same time, the cleanliness and safety of the components can be maintained.

[0012] Preferably, a handle is fixedly connected to the upper surface of the protective cover.

[0013] The effects achieved by the above components are as follows: The user can remove the protective cover from the support plate through the handle, which is convenient for inspecting and replacing the components.

[0014] Preferably, a collecting device is provided on one side of the body. The collecting device includes two limiting plates. The side of the two limiting plates close to each other is fixedly connected to the body. A fixing plate is fixedly connected to the side of the two limiting plates close to each other. A box is provided on the lower surface of the fixing plate. A clamping block is fixedly connected to each side of the box, and the clamping block is in interference connection with the limiting plate.

[0015] The effects achieved by the above components are as follows: When the processing is completed and the circuit board is removed, the circuit board is placed on the side of the adjusting plate away from the support table. At this time, the adjusting plate will drive the circuit board to move to the fixing plate. Due to gravity, the circuit board will fall along the direction of the fixing plate until it falls into the box, thus achieving the effect of storage.

[0016] Preferably, four pulleys are provided on the lower surface of the box, and the pulleys are evenly distributed on the lower surface of the box.

[0017] The effects achieved by the above components are as follows: The convenience of moving the box is increased, which is beneficial for the staff to transport the circuit board.

[0018] Preferably, anti-slip strips are provided on the upper surface of the fixing plate.

[0019] The effects achieved by the above components are as follows: The anti-slip strip can provide additional friction and increase the contact area between the circuit board and the fixing plate, thus ensuring that the circuit board can slide into the box stably.

[0020] In summary, the beneficial effects of this application are as follows:

[0021] In this application, when pasting components on the circuit board, first place the circuit board on the support table, then start the drive motor. The drive motor drives the screw to rotate, and the screw drives the wheel disc on its arc surface to rotate. The rotation of the wheel disc will drive the belt to rotate, thereby driving another wheel disc to rotate. The rotation of the wheel disc will drive the lead screw to rotate together. When the screw and the lead screw rotate, due to the double-thread provided on their surfaces, the two adjusting plates on their surfaces will move in opposite directions until the circuit board is firmly clamped. Then turn off the drive motor. Subsequently, the component placement head will pick up the components and paste them on the circuit board. After the pasting is completed, start the drive motor again to separate the adjusting plate from the circuit board. The function of setting the protective cover is to protect the drive motor from external damage.

[0022] In this application, when removing the circuit board and replacing it with the next one, the circuit board can be directly placed on the side of the positioning block close to the collection device. At this time, the positioning block will push the circuit board towards the collection device. When the circuit board reaches the fixing plate, due to the action of gravity, the circuit board will move along the direction of the fixing plate until it falls into the box. After all the processing is completed, directly pull the box, and the circuit board can be conveniently moved to the required position. The function of setting the anti-slip strip is to increase the friction between the circuit board and the fixing plate directly, prevent the circuit board from shifting and flying off the fixing plate, and enable it to fall into the box stably.

[0028] Refer to Figure 1 As shown in the figure, the present application provides a technical solution: an electronic component chip mounter, which includes a cylinder 2 fixedly connected to the upper surface of a machine body 1, the output end of the cylinder 2 is fixedly connected to a chip mounter head 3, a support table 4 is arranged below the chip mounter head 3, the lower surface of the support table 4 is fixedly connected to the machine body 1, a fixing device 5 is arranged on the upper surface of the machine body 1, and a collection device 6 is arranged on one side of the machine body 1.

[0029] Next, specifically describe the specific settings and functions of its fixing device 5 and collection device 6.

[0030] Refer to Figure 3As shown in the figure, in this embodiment: The fixing device 5 includes four positioning blocks 501. The lower surfaces of the four positioning blocks 501 are fixedly connected to the machine body 1. The four positioning blocks 501 are evenly distributed on the upper surface of the machine body 1. One end of the machine body 1 is fixedly connected to a support plate 506. A driving motor 507 is provided on the upper surface of the support plate 506. The output end of the driving motor 507 is fixedly connected to a screw rod 502. The screw rod 502 threadedly penetrates through two positioning blocks 501. A double-thread is provided on the arc surface of the screw rod 502. Two adjusting plates 503 are threadedly connected to the arc surface of the screw rod 502. The inner wall of the adjusting plate 503 is threadedly connected to a lead screw 512. The lead screw 512 threadedly penetrates through the positioning block 501. A double-thread is provided on the arc surface of the lead screw 512. On the side of the screw rod 502 and the lead screw 512 close to the output end of the driving motor 507, a wheel disc 504 is fixedly connected. A belt 505 is rotatably connected to the arc surfaces of the two wheel discs 504. When the driving motor 507 is started, the driving motor 507 drives the screw rod 502 to rotate. The rotation of the screw rod 502 indirectly drives the lead screw 512 to rotate. Because double-threads are provided on their surfaces, the adjusting plates 503 on their arc surfaces will move in opposite directions until the circuit board is clamped and fixed. A chute 508 is provided on the upper surface of the machine body 1. A connecting column 509 is slidably connected to the inner wall of the chute 508. The upper surface of the connecting column 509 is fixedly connected to the adjusting plate 503. When the screw rod 502 and the lead screw 512 drive the adjusting plate 503 to move towards the circuit board, the adjusting plate 503 can slide along the chute 508 under the support of the connecting column 509, playing a role of limiting and supporting it. A protective cover 510 is provided on the upper surface of the support plate 506, which can protect the driving motor 507 from being affected and damaged by the external environment. At the same time, it can also keep the components clean and safe. A handle 511 is fixedly connected to the upper surface of the protective cover 510. The user can remove the protective cover 510 from the support plate 506 through the handle 511, which is convenient for inspecting and replacing the components.

[0031] Referring to Figure 4As shown in the figure, in this embodiment: A collecting device 6 is provided on one side of the machine body 1. The collecting device 6 includes two limiting plates 61. The sides of the two limiting plates 61 close to each other are fixedly connected to the machine body 1. A fixing plate 62 is fixedly connected to the sides of the two limiting plates 61 close to each other. A box 63 is provided on the lower surface of the fixing plate 62. A clamping block 64 is fixedly connected to each side of the box 63. The clamping block 64 is in interference connection with the limiting plate 61. When the circuit board is removed after processing is completed, the circuit board is placed on the side of the adjusting plate 503 away from the support platform 4. At this time, the adjusting plate 503 will drive the circuit board to move to the fixing plate 62. Due to gravity, the circuit board will fall along the direction of the fixing plate 62 until it falls into the box 63, thus achieving the effect of storage. Four pulleys 65 are provided on the lower surface of the box 63. The pulleys 65 are evenly distributed on the lower surface of the box 63, increasing the convenience of moving the box 63 and facilitating the staff to transport the circuit board. Anti-slip strips 66 are provided on the upper surface of the fixing plate 62. The anti-slip strips 66 can provide additional friction and increase the contact area between the circuit board and the fixing plate 62, thereby ensuring that the circuit board can slide stably into the box 63.

[0032] Working principle: When pasting components on the circuit board, first place the circuit board on the support platform 4. Then start the drive motor 507. The drive motor 507 drives the screw 502 to rotate. The screw 502 drives the disk 504 on its arc surface to rotate. The rotation of the disk 504 will drive the belt 505 to rotate, thereby driving another disk 504 to rotate. The rotation of the disk 504 will drive the lead screw 512 to rotate together. The screw 502 and the lead screw 512 rotate. Due to the double-thread provided on their surfaces, the two adjusting plates 503 on their surfaces will move in opposite directions until they firmly clamp the circuit board. Then turn off the drive motor 507. Subsequently, the chip placement head 3 will pick up the components and paste the components on the circuit board. After the pasting is completed, start the drive motor 507 again to separate the adjusting plate 503 from the circuit board. The function of setting the protective cover 510 is to protect the drive motor 507 and prevent it from being damaged by the outside.

[0033] When removing the circuit board and replacing it with the next one, the circuit board can be directly placed on the side of the positioning block 501 close to the collecting device 6. At this time, the positioning block 501 will push the circuit board towards the collecting device 6. When the circuit board reaches the fixing plate 62, due to the action of gravity, the circuit board will move along the direction of the fixing plate 62 until it falls into the box 63. After all the processing is completed, directly pull the box 63, and the circuit board can be conveniently moved to the required position. The function of setting the anti-slip strips 66 is to increase the friction between the circuit board and the fixing plate 62 directly, prevent the circuit board from shifting and flying off the fixing plate 62, and enable it to stably fall into the box 63.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.
