Description

TECHNICAL FIELD

[0001] The utility model relates to a burning equipment, concretely relates to a circuit board burning device. BACKGROUND

[0002] The vehicle-mounted radar is usually composed of a sensor, a controller and a wire harness, wherein the sensor is installed on the front or tail bumper of the vehicle, and the controller is installed on the vehicle body. The sensor transmits and receives ultrasonic waves, and the signals are transmitted to the controller for operation, so that the driver can master the conditions in front of and behind the vehicle, and avoid collision between the vehicle body and obstacles. The controller mainly includes a shell and a circuit board. In order to have computing ability, the circuit board needs to be programmed during the production process, so as to record specific programs into the chip on the circuit board.

[0003] For example, the patent document with the name of "burning equipment" (document number CN214827110U) discloses a technical solution including two positioning mechanisms with positioning conveyors, a taking and placing mechanism, multiple burning machines, and a discharging clamping mechanism. The two positioning mechanisms are arranged in sequence. The taking and placing mechanism includes a taking and placing manipulator located adjacent to the two positioning mechanisms, a taking and placing cross beam rotatably installed on the taking and placing manipulator, and at least one taking and placing clamping assembly installed on the taking and placing cross beam. The product reaches the positioning conveyor on the first positioning mechanism, and the product is clamped by the manipulator to one of the burning machines for burning. The manipulator can also clamp the product completed by the burning machine to the positioning conveyor on the second positioning mechanism, and the product moves along the positioning conveyor to the discharging clamping mechanism. The discharging clamping mechanism clamps the product completed by the burning on the positioning conveyor to the next processing position, and completes the burning of the product.

[0004] In the automatic production line, the product conveying line is usually composed of multiple conveying belts connected in sequence. The material carrier is generally placed on the conveying belt, and the manipulator places the burned circuit board on the carrier on the discharging conveying belt, and then the conveying belt conveys the carrier and the product thereon to the next process for processing. During the process, the carrier needs to be parked at the specified position when it is conveyed to the specified position on the burning station. Then the manipulator accurately places the product on the groove or frame on the carrier along the preset moving path, so as to facilitate the subsequent process. Since the carrier is placed on the belt surface of the conveying belt, the relative position between the two is only guaranteed by the friction therebetween. When the carrier stops at the specified parking position, the carrier will slide relative to the belt surface due to inertia and other factors. After a long time, the position where the carrier stops will deviate from the specified position, so that the carrier cannot be accurately parked at the specified parking position, and the product cannot be accurately placed at the specified position on the carrier, which causes the positioning of the product on the carrier to fail, and further affects the normal operation of the subsequent process. SUMMARY

[0005] This invention provides a circuit board programming device. When the carrier disk is transported to a designated parking space, a constraint mechanism constrains the carrier disk to ensure that the carrier disk can stop at the designated parking space without excessive deviation.

[0006] To achieve the above objectives, the technical solution adopted is as follows: a circuit board programming device, including a frame, on which a programming unit, a feeding conveyor unit, and a horizontally placed unloading conveyor belt are respectively arranged. The gripping unit grips the board to be programmed on the feeding conveyor unit and moves it to the programming unit, or grips the programmed board on the programming unit and moves it to the unloading conveyor belt. A carrier tray is placed on the unloading conveyor belt, and the carrier tray is provided with a receiving groove for accommodating the programmed board. A carrier tray parking position is provided on the conveying path of the unloading conveyor belt. When the carrier tray is conveyed to the carrier tray parking position by the unloading conveyor belt, the constraint mechanism is in a stop position that constrains the carrier tray to the carrier tray parking position or in a separation position that avoids the movement path of the carrier tray.

[0007] Compared with the prior art, the technical effect of this utility model is as follows: by setting a constraint mechanism at the location of the tray parking position, when the tray is transported to the tray parking position by the unloading conveyor belt, the constraint mechanism can constrain the tray within the tray parking position and prevent it from deviating from the designated position, thereby ensuring the accurate position of the tray after parking. The gripping unit can also grip the product along its pre-set moving path and accurately place it into the receiving slot on the tray, which is convenient for the next process to continue processing.

[0014] The following is in conjunction with the appendix Figures 1-6 The present invention will be further described in detail below, including related content:

[0015] The application discloses a circuit board burning device, which comprises a rack 10, a burning unit 20, a feeding conveying unit 30 and a horizontal discharging conveying belt 40 arranged on the rack 10 respectively, a grabbing unit 50 is used for grabbing a to-be-burned board piece A1 on the feeding conveying unit 30 and moving the to-be-burned board piece A1 to the burning unit 20 or grabbing a burned board piece A2 on the burning unit 20 and moving the burned board piece A2 to the discharging conveying belt 40, a carrier disc 60 is arranged on the discharging conveying belt 40, the carrier disc 60 is provided with a containing groove 61 used for containing the burned board piece A2, a carrier disc parking position 41 is arranged on a conveying path of the discharging conveying belt 40, and a constraint mechanism 70 is arranged at a position where the carrier disc 60 is constrained in a stop position in the carrier disc parking position 41 or is in a separation position which is mutually avoided with a movement path of the carrier disc 60 when the carrier disc 60 is conveyed to the carrier disc parking position 41 along with the discharging conveying belt 40.

[0016] In the above scheme, the constraint mechanism 70 is arranged at a position where the carrier disc parking position 41 is arranged on the conveying path of the discharging conveying belt 40, when the carrier disc 60 is conveyed to the carrier disc parking position 41 along with the discharging conveying belt 40, the constraint mechanism 70 can constrain the carrier disc 60 in the carrier disc parking position 41 and cannot deviate from a specified position, so that the position of the carrier disc 60 after parking is accurate, and the grabbing unit 50 can grab the burned board piece A2 on the burning unit 20 along a movement path which is set in advance. Since the movement path of the grabbing unit 50 is set in advance, the burned board piece A2 can be accurately placed in the containing groove 61 on the carrier disc 60 at the carrier disc parking position 41 under the premise that the stop position of the carrier disc 60 is accurate, so that the burned board piece A2 is accurately positioned and placed, and the next process can continue to be processed. After the burned board piece A2 is placed in the containing groove 61, the constraint mechanism 70 is in the separation position which is mutually avoided with the movement path of the carrier disc 60, so that the constraint mechanism 70 and the movement path of the carrier disc 60 do not interfere with each other and affect the conveying of the carrier disc 60 to the downstream.

[0017] It should be noted that the grabbing unit 50 is an automatic mechanical hand, when the burned board piece A2 is placed in the containing groove 61 on the carrier disc 60, the relative position of the burned board piece A2 in the containing groove 61 is not required to be accurate and error-free, as long as the error range set in advance is not deviated.

[0018] Further, the blanking conveying belt 40 comprises two conveying belt units 42 arranged in parallel and at intervals, the two conveying belt units 42 are located in the same horizontal plane and the carrier plate 60 is arranged on the upper belt surface of the two conveying belt units 42, and the far side belt edges of the two conveying belt units 42 are arranged with guide rails 43 along the conveying direction of the conveying belt units 42, and the carrier plate 60 and the guide rails 43 form a guiding sliding fit. Through the arrangement of the guide rails 43, the displacement of the carrier plate 60 in the width direction of the conveying belt units 42 can be limited, so as to avoid the carrier plate 60 from sliding to the two sides of the blanking conveying belt 40, and at the same time, it is also to ensure that the carrier plate 60 is conveyed to the downstream with the blanking conveying belt 40 in a constant posture, so as to accurately process the burned plate A2 placed on the carrier plate 60 at a specific position.

[0019] As a preferred solution, the constraint mechanism 70 comprises at least two positioning pins 71 arranged vertically and at intervals, the upper end of the positioning pin 71 is provided with a tapered head 711 which is small at the upper end and large at the lower end, when the carrier plate 60 is located in the carrier parking position 41, the driving mechanism drives the positioning pin 71 to move upward to the top of the tapered head 711 to penetrate into the positioning hole 62 on the carrier plate 60 or drives the positioning pin 71 to move downward to the separation position where the tapered head 711 and the positioning hole 62 on the carrier plate 60 are separated from each other. In this solution, by using the cooperation between the positioning pin 71 and the positioning hole 62 on the carrier plate 60, the positioning pin 71 penetrates into the positioning hole 62, which can limit the carrier plate 60, preventing the carrier plate 60 from continuing to displace along the blanking conveying belt 40.

[0020] In addition, the upper end of the positioning pin 71 is provided with a tapered head 711 which is small at the upper end and large at the lower end, and the tapered head 711 has a tapered guide surface. Even if there is a slight error in the relative position between the hole domain of the positioning hole 62 and the positioning pin 71 after the carrier plate 60 is parked, when the tapered head 711 penetrates into the positioning hole 62, the tapered guide surface of the tapered head 711 and the hole domain of the positioning hole 62 are pushed against each other, which can also force the carrier plate 60 to further displace a certain amount, so as to correct the position of the carrier plate 60 and ensure the accuracy of the parking position.

[0021] In order to further ensure that the carrier plate 60 is parked more accurately after the positioning pin 71 penetrates into the positioning hole 62, the positioning hole 62 is a tapered hole with a large lower end aperture and a small upper end aperture, and the taper of the positioning hole 62 is the same as that of the tapered head 711, and the lower end aperture diameter of the positioning hole 62 is greater than the lower end diameter of the tapered head 711. The tapered head 711 and the tapered positioning hole 62 are guided and matched with each other, after the tapered head 711 penetrates into the positioning hole 62, the positioning hole 62 can tend to be arranged with the same core as the tapered head 711, realizing the relative arrangement of "point and point", so as to make the correction degree of the carrier plate 60 more accurate.

[0022] In combination with Figure 3 With Figure 6As shown, the lower ends of the positioning pins 71 are jointly connected with a mounting plate 72, and the driving unit 73 drives the mounting plate 72 to move upward to a stop position of the tapered head 711 to penetrate into the positioning hole 62 on the carrier disc 60 or to move downward to a separation position of the tapered head 711 to separate from the positioning hole 62 on the carrier disc 60. The mounting plate 72 serves as a base to facilitate the arrangement of the positioning pins 71, and the driving unit 73 drives the mounting plate 72 to move upward or downward, so that the positioning pins 71 on the mounting plate 72 can be synchronously lifted or lowered to simultaneously penetrate into or move out of the corresponding positioning holes 62 on the carrier disc 60.

[0023] In addition, the mounting plate 72 is connected with at least three vertically arranged support columns 74, the support columns 74 are arranged at intervals, the upper end faces of the support columns 74 are located at the same horizontal plane and are lower than the upper end face of the tapered head 711, the upper end faces of the support columns 74 are connected with each other to form a polygon, and the support columns 74 lift the lower disc face of the carrier disc 60 to separate the lower disc face from the lower material conveying belt 40 when the mounting plate 72 moves upward to the stop position; when the mounting plate 72 moves downward to the separation position, the upper end faces of the support columns 74 are separated from the lower disc face of the carrier disc 60 and the carrier disc 60 falls back onto the lower material conveying belt 40. When the carrier disc 60 is located at the position of the carrier disc parking position 41, under the premise that the positioning pins 71 position the carrier disc 60, the support columns 74 are used to support the carrier disc 60 for corresponding operation, so that the carrier disc 60 is separated from the lower material conveying belt 40, the lower material conveying belt 40 can continue to operate to transport the upstream carrier disc 60 close to the carrier disc parking position 41, thereby shortening the conveying distance between the subsequent carrier disc 60 and the carrier disc parking position 41, which is beneficial to improve the processing efficiency of the subsequent carrier disc 60.

[0024] Here, because the upper end faces of the support columns 74 are connected with each other to form a polygon, the area enclosed by the upper ends of the support columns 74 in sequence is a supporting surface to provide stable supporting effect for the carrier disc 60.
