Abstract
The utility model relates to a holddown device of a circuit board. The device comprises a base (1), a control device (2), a cylinder (3), a platen (4), a spring (5), and a base plate (6). The base plate (6) is fixedly installed on the central position of the upper surface of the base (1). The control device (2) is disposed on the base (1). The cylinder (3) is fixed under the control device (2). The output end of the cylinder (3) is vertically downward, and is fixedly connected with the upper end of the spring (5). The platen (4) is disposed above the base plate (6). Four corners on the platen (4) are provided with spring seats (7). The lower end of the spring (5) is fixed on the spring seat (7). The platen (4) compresses a circuit board (9) on the base plate (6). The device is advantaged in that compaction and positioning are accurate, stress of the circuit board is uniform, and the device is simple in operation and low in manufacturing cost.
Description
Technical field
The utility model relates to the hold down gag of the production equipment technical field, particularly a kind of wiring board of wiring board.
Background technology
Wiring board is printed circuit board, claims again printed circuit board (PCB), is the supplier of electronic devices and components electrical connection, and the major advantage that adopts circuit board is the mistake that greatly reduces wiring and assembling, has improved the gentle productive labor rate of Automated water.Wiring board be take insulation board as base material, be cut into certain size, on it, at least have a conductive pattern cloth porose (as component hole, fastener hole, plated-through hole etc.), be used for replacing installing the chassis of electronic devices and components in the past, and realize interconnecting between electronic devices and components.
Wiring board in process of production, wiring board is processed after need to fixing again, traditional equipment that is fixed is generally to press in the circuit board by the output immediate roof of cylinder, such working method makes wiring board discontinuity, easily cause wiring board fracture, and there is no positioner, wiring board cannot accurately be located on base, thereby cause the process that is fixed of wiring board to seem more complicated, and need to use other auxiliary equipment to position wiring board.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of hold down gag that compresses the wiring board of stressed even, the simple to operate and low cost of manufacture of registration, wiring board is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of hold down gag of wiring board, it comprises base, control device, cylinder, pressing plate, spring and backing plate, described backing plate is fixedly mounted on the center of base upper surface, control device is arranged at base top, cylinder is fixed on the below of control device, the output of cylinder straight down, and be fixedly linked with the upper end of spring, the top of backing plate is provided with pressing plate, on four jiaos of pressing plate top, be arranged at spring base, the lower end of spring is fixed on spring base, pressing plate is pressed on wiring board on backing plate.
On described backing plate, be also provided with a plurality of alignment pins, and match with the location hole being arranged on wiring board.
Described pressing plate is the high plank frames in middle low both sides.
The utlity model has following advantage:
1, a plurality of alignment pins in location are set on backing plate, wiring board is coordinated with location hole by alignment pin, registration, compresses pressing plate in the circuit board by Telescopic-cylinder, compresses more firm.
2, between cylinder and pressing plate, spring is set, make pressing plate to press down process more steady, and spring plays cushioning effect, wiring board is stressed more even.
3, the location hole of wiring board is coordinated with alignment pin, and be placed on backing plate, control cylinder presses down, and pressing plate is pressed in the middle part of wiring board, realizes compaction process, simple to operate.
4, the utility model is simple in structure, and each parts cost is low, and its manufacturing process is simple and easy to realize, and significantly reduces the manufacturing cost of equipment.

Fig. 2 is the plan structure schematic diagram of base;
Fig. 3 is the structural representation of wiring board;
Fig. 4 is working state schematic representation of the present utility model;
In figure: 1-base, 2-control device, 3-cylinder, 4-pressing plate, 5-spring, 6-backing plate, 7-spring base, 8-alignment pin, 9-wiring board, 10-location hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection range of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of hold down gag of wiring board, it comprises base 1, control device 2, cylinder 3, pressing plate 4, spring 5 and backing plate 6, described backing plate 6 is fixedly mounted on the center of base 1 upper surface, control device 2 is arranged at base 1 top, cylinder 3 is fixed on the below of control device 2, the output of cylinder 3 straight down, and be fixedly linked with the upper end of spring 5, the top of backing plate 6 is provided with pressing plate 4, on four jiaos of pressing plate 4 tops, be arranged at spring base 7, the lower end of spring 5 is fixed on spring base 7, and pressing plate 4 is pressed on wiring board 9 on backing plate 6.
As shown in Figure 2, Figure 3 and Figure 4, on described backing plate 6, be also provided with a plurality of alignment pins 8, and match with the location hole 10 being arranged on wiring board 9.
As shown in Figure 1, described pressing plate 4 is the high plank frames in middle low both sides, prevents from being arranged at the lower surface that alignment pin 8 on backing plate 6 withstands on pressing plate 4.
The course of work of the present utility model is as follows: as shown in Figure 1 and Figure 4, cylinder 3 shrinks, to on pressing plate 4, lift to extreme higher position, location hole on wiring board 9 10 is alignd with alignment pin 8, and wiring board 9 is placed on backing plate, control device 2 control cylinders 3 stretch out, pressing plate 4 is pressed on wiring board 9, spring 5 plays cushioning effect between cylinder 3 and pressing plate 4, makes the stressed more even of wiring board 9, effectively prevents that wiring board 9 from breaking.
