Description

Technical Field

[0001] This utility model relates to the field of precision machining technology, specifically to a fixture for programming vehicle-mounted cameras. Background Technology

[0002] The process of burning programs to vehicle cameras requires holding the PCB board by hand, which has the following technical drawbacks: the board is small and difficult to operate, which can easily lead to program burning failure; and the PCB board is easily damaged when the hand touches it, resulting in low efficiency and making it unsuitable for mass production.

[0003] Therefore, designing a fixture for burning software to vehicle-mounted cameras has become an urgent problem to be solved. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a fixture for burning programs to vehicle-mounted cameras, so as to solve at least one of the above-mentioned technical problems.

[0005] The technical solution of this utility model is: a fixture for programming a vehicle-mounted camera, including a measuring base, a fixture frame on the top surface of the measuring base, the fixture frame including a vertical plate, a cylinder on one side end of the vertical plate, the piston end of the cylinder being arranged downwards and connected to an upper pressure block, a number of product limiting blocks arranged at intervals on the top surface of the measuring base, a camera PCB being placed in the ejector pin groove of the product limiting block, and an ejector pin on the bottom surface of the upper pressure block, the ejector pin being able to contact the camera PCB under the drive of the piston end of the cylinder to limit the camera PCB.

[0006] This invention uses the upper pressure block's ejector pin, driven by the cylinder piston end, to contact the camera PCB, limiting the camera PCB's position. This results in good programming stability and a high success rate for one-time programming, solving the technical defects of small board size, difficult operation, and easy program programming failure. It also eliminates the need for hand contact with the circuit board, thus solving the technical defects of easy PCB board damage, low efficiency, and unsuitability for mass production when the hand touches the circuit board.

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] See Figure 1-3 The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0013] Example 1: A fixture for programming vehicle-mounted cameras, referenced Figure 1 , Figure 2 , Figure 3 The device includes a measuring base 7, on the top surface of which is a fixture frame 6. The fixture frame 6 includes a vertical plate, and a cylinder 2 is mounted on one end face of the vertical plate. The piston end of the cylinder 2 is downwardly positioned and connected to an upper pressure block 1. The top surface of the measuring base 7 also has five spaced product limiting blocks 4. A camera PCB is placed in the ejector pin slot of each product limiting block 4. Ejector pins are mounted on the bottom surface of the upper pressure block 1. These ejector pins, driven by the piston end of the cylinder 2, contact the camera PCB to limit its movement. This invention utilizes the ejector pins of the upper pressure block, driven by the piston end of the cylinder, to contact the camera PCB and limit its movement. This results in good programming stability and a high one-time programming success rate, solving the technical defects of small boards, difficult operation, and easy program programming failure. It also eliminates the need for manual contact with the circuit board, reducing the probability of board damage and addressing the technical defects of low efficiency and unsuitability for mass production caused by manual contact with the circuit board.

[0014] Example 2: Based on Example 1, a guide rail 3 with spacing is provided on one end face of the upright plate. The cylinder 2 is located between two guide rails 3, and both ends of the upper pressure block 1 are respectively mounted on the guide rails 3 via sliders. This utility model uses two guide rails to guide the movement of the upper pressure block by mounting both ends of the upper pressure block on the guide rails via sliders.

[0015] Example 3: Based on Example 1, a measuring tool PCB board 11 is provided inside the measuring tool base 7, and the measuring tool PCB board 11 is connected to the power supply via a power cable 9; a measuring tool base plate 12 is provided on the bottom surface of the measuring tool base 7, and a USB cable 8 is also provided on the measuring tool PCB board 11, which is connected to all camera PCBs. This utility model uses a measuring tool base plate connected to the measuring tool base, and the measuring tool PCB board is installed in the space between the measuring tool base plate and the measuring tool base.

[0016] Example 4: Based on Example 3, the measuring base 7 has an inclined surface on its vertical surface near the product limiting block 4, and a switch button 10 is provided on the inclined surface. This utility model uses an inclined surface on the vertical surface of the measuring base near the product limiting block, and a switch button is provided on the inclined surface for easy operation.

[0017] Example 5: Based on Example 4, the cylinder 2 is connected to the air source via air pipe 5 and a solenoid valve. The solenoid valve's terminals are connected to the power supply via wires, a relay, and a switch button 10. The relay is also connected to the measuring instrument PCB board 11. In this invention, the solenoid valve's terminals are connected to the power supply via wires, a relay, and a switch button. When the solenoid valve's coil is energized, the internal movable iron core is attracted by electromagnetic force, driving the valve core to move, thereby adjusting the valve's opening and closing state.

[0018] Example 6: Based on Example 5, the upright plate is further equipped with spaced limit switches. Both limit switches are connected to a relay. The lower limit switch is close to the product limit block 4, and the upper limit switch is close to the middle of the upright plate. The upper pressure block 1's range of motion is between the two limit switches. This utility model uses two limit switches: the lower limit switch is close to the product limit block, and the upper limit switch is close to the middle of the upright plate. When the upper pressure block contacts the limit switch, the limit switch's output signal is connected to the relay, and the relay's output signal is connected to the control circuit of the solenoid valve, changing the piston movement state of the cylinder. This connection method can isolate the control signal, has high anti-interference capability, and is suitable for complex control and high operation frequency applications.

[0019] Example 7: Based on Example 1, the fixture frame 6 further includes spaced stiffeners. Two stiffeners connect the top surface of the upright plate and the measuring base 7, and the two stiffeners are located at the end away from the product limiting block 4. This utility model uses spaced stiffeners to connect the top surface of the upright plate and the measuring base, increasing the structural strength of the upright plate.

[0020] The operation process of this utility model is as follows: First, place 5 camera PCBs into the ejector pin slots of the product limiting block 4 in sequence. At the same time, press the start button on both the left and right sides of the switch 10. The solenoid valve opens, the piston of cylinder 2 extends, and drives the upper pressure block 1 to press down to the lower limit switch (the predetermined position below, see...) under the push of high-pressure gas. Figure 2 The output signal of the lower limit switch is connected to the relay, and then the output signal of the relay is connected to the control circuit of the solenoid valve. The cylinder 2 maintains a load state. At the same time, the output signal of the relay is connected to the measuring instrument PCB board 11. The measuring instrument PCB board 11 programs 5 PCS camera PCBs through the USB cable 8, supporting simultaneous programming of 5 PCS camera PCBs with high programming efficiency. After programming is completed, the operator presses the left and right switch buttons 10 simultaneously again. The solenoid valve closes, and the piston of cylinder 2 drives the upper pressure block 1 to rise to the upper limit switch (the predetermined position above, see the limit switch above) under the push of high pressure gas. Figure 3 The output signal of the limit switch above is connected to the relay, and then the output signal of the relay is connected to the control circuit of the solenoid valve. The piston of cylinder 2 stops returning to its original position. The camera PCB after the programming is completed is then taken out in sequence to complete the programming.

[0021] The above-described embodiments are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
