Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and more specifically, to a positioning device for circuit board manufacturing. Background Technology

[0002] As the support for electronic components and the carrier for electrical connections, circuit boards are made using electronic printing technology, making circuits more miniaturized and intuitive. They play an important role in the mass production of fixed circuits and the optimization of electrical layout. During production, circuit boards usually need to be positioned for drilling.

[0003] A search revealed a positioning device for circuit board production disclosed in Chinese Patent Publication No. CN 217088261 U. Although the device facilitates positioning by placing the circuit board between two positioning blocks and then using a clamping mechanism to drive the circuit board close to the positioning mechanism, the position of the two positioning blocks cannot be adjusted. This limits its applicability to circuit boards of different widths and makes it unsuitable for positioning circuit boards of different widths. Therefore, this invention designs a positioning device for circuit board production to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a positioning device for circuit board production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioning device for circuit board production includes a machine base, a guide frame, a punching head, and two symmetrically distributed transmission seats. The guide frame is fixedly mounted on the machine base, and the machine seat is slidably sleeved on the outside of the guide frame. The punching head is fixedly mounted on the bottom end of the machine seat. A drive assembly for moving the machine seat and the punching head is provided on the guide frame. An electric push rod is fixedly mounted on the front side of the machine base. A pressure sensor is fixedly mounted on the telescopic end of the electric push rod via a carrier. A push plate is fixedly mounted on the force-receiving end of the pressure sensor. An elastic pad is fixedly mounted on the end face of the push plate. A transmission stud is threadedly connected to the rear side of the machine base via a side block. A positioning baffle is rotatably connected to the end of the transmission stud. The positioning baffle is slidably connected to the machine base. Positioning blocks are fixedly connected to the opposite ends of the two transmission seats. A positioning motor is fixedly mounted on the left side of the machine base. A bidirectional stud is fixedly connected to the drive end of the positioning motor. The two transmission seats are respectively threaded onto the positive and negative thread portions of the bidirectional stud. The guide frame is slidably sleeved on the outside of the transmission seats.

[0007] As a preferred embodiment of this utility model, the drive assembly includes a moving motor and a lead screw shaft. The moving motor is fixedly installed on the side of the guide frame, the lead screw shaft is fixedly connected to the drive end of the moving motor, and the base is threaded onto the outside of the lead screw shaft.

[0008] As a preferred embodiment of this utility model, a bearing I is fixedly installed on the inner side of the guide frame, and the bearing I is rotatably connected to one end of the lead screw shaft.

[0009] As a preferred embodiment of this utility model, a controller is fixedly installed on the machine base, the output end of the pressure sensor is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input end of the electric push rod.

[0010] As a preferred embodiment of this utility model, a bearing II is fixedly installed on the right side of the machine base, and the bearing II is rotatably connected to one end of a double-ended stud.

[0011] As a preferred embodiment of this utility model, a knob block is fixedly installed at one end of the transmission stud, and the cross-sectional shape of the knob block is a regular hexagon.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention places the circuit board on a machine base, positioning it between two positioning blocks. Rotating the drive stud causes the positioning baffle to slide along the machine base, facilitating longitudinal adjustment of the baffle's position. The rear edge of the circuit board contacts the positioning baffle. An electric push rod drives a push plate and an elastic pad to move towards the front edge of the circuit board, thus positioning and clamping it. A pressure sensor monitors the clamping force on the circuit board in real time, ensuring a stable positioning and clamping effect. For circuit boards of different widths, a positioning motor drives a bidirectional stud to rotate, causing the two drive seats to slide closer or further apart along the guide frame. This facilitates lateral adjustment of the two positioning blocks, effectively improving the adjustability of the positioning device structure and conveniently meeting the positioning and clamping needs of circuit boards of different widths, thus expanding its applicability.

[0020] like Figures 1 to 4 As shown, this utility model provides a positioning device for circuit board production, including a machine base 1, a guide frame 2, a punching head 3, and two symmetrically distributed transmission seats 501.

Push plate 603, elastic pad 604 is fixedly installed on the end face of push plate 603, transmission stud 701 is threadedly connected to the rear side of machine base 1 through side block 7, positioning baffle 702 is rotatably connected to the end of transmission stud 701, positioning baffle 702 is slidably connected to machine base 1, positioning block 5 is fixedly connected to the opposite ends of two transmission seats 501, positioning motor 8 is fixedly installed on the left side of machine base 1, bidirectional stud 801 is fixedly connected to the drive end of positioning motor 8, two transmission seats 501 are respectively threaded into the positive and negative threaded parts of bidirectional stud 801, and guide frame 2 is slidably sleeved on the outside of transmission seats 501.

[0021] Among them, such as Figure 2As shown, the drive assembly 4 includes a moving motor 401 and a lead screw 402. The moving motor 401 is fixedly installed on the side of the guide frame 2, and the lead screw 402 is fixedly connected to the drive end of the moving motor 401. The machine base 201 is threaded onto the lead screw 402. The moving motor 401 drives the lead screw 402 to rotate, which can drive the machine base 201 and the drilling head 3 to move left and right.

[0022] Among them, such as Figure 2 As shown, a bearing I202 is fixedly installed on the inner side of the guide frame 2. The bearing I202 is rotatably connected to one end of the lead screw shaft 402, thereby ensuring the rotational stability of the lead screw shaft 402.

[0023] Among them, such as Figure 1 As shown, a controller 101 is fixedly installed on the machine base 1. The output end of the pressure sensor 602 is electrically connected to the input end of the controller 101, and the output end of the controller 101 is electrically connected to the input end of the electric push rod 6.

[0026] The working principle of this utility model:

[0027] During use, the circuit board is placed on the machine base 1, positioning it between two positioning blocks 5. The drive stud 701 is rotated using the knob block 703, which causes the positioning baffle 702 to slide along the machine base 1, facilitating longitudinal adjustment of the position of the positioning baffle 702. The rear side of the circuit board contacts the positioning baffle 702. The electric push rod 6 drives the push plate 603 and the elastic pad 604 to move towards the front side of the circuit board, thus positioning and clamping the circuit board. The pressure sensor 602 can monitor the clamping force on the circuit board in real time. If the clamping force reaches the preset value, the controller 101 controls the electric push rod 6 to stop driving, ensuring a stable positioning and clamping effect on the circuit board. When encountering circuit boards of different widths, the positioning motor 8 drives the bidirectional stud 801 to rotate, which causes the two drive seats 501 to slide closer or further apart along the guide frame 2, thereby facilitating lateral adjustment of the position of the two positioning blocks 5 and conveniently meeting the positioning and clamping requirements of circuit boards of different widths.
