DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1: This embodiment is intended to help solve the problem that during the production and transportation of PCBs, the material frame position offset or improper stacking may affect the production quality of the production line, thereby causing incorrect assembly, breakage or damage in PCB manufacturing. If these problems are not discovered and handled in a timely manner, they may further affect the production quality and delivery time of the entire product line, thereby causing delays in customer delivery. Please refer to Figure 1-5A PCB material frame with automatic reset function includes a main body box 110, a mounting plate 120 is installed inside the main body box, a slide rail 121 is arranged on the side of the mounting plate 120, a material transporting plate 122 is arranged on the side of the mounting plate 120, a slider 123 is arranged at the bottom of the material transporting plate 122, the slider 123 is slidably connected to the slide rail 121, a volute spring 124 is arranged on the side of the mounting plate 120, and the volute spring 124 is arranged on the side of the material transporting plate 122.

[0024] The side of the mounting plate 120 is connected to a fixed plate 130, two fixed plates 130 are provided, a rotating shaft 131 is connected between the two fixed plates 130, a scroll drum 133 is provided on the side of the mounting plate 120, a scroll shaft 134 is connected to the middle of the scroll drum 133, a scroll spring 124 is sleeved on the side of the scroll shaft 134, one end of the output shaft of the servo motor 132 is connected to the end of the key of the rotating shaft 131, and the other end of the output shaft of the servo motor 132 is connected to the end key of the scroll shaft 134. The arrangement of the scroll drum 133 and the scroll shaft 134 allows the scroll spring 124 to be conveniently sleeved on the side of the scroll shaft 134. The connection between the output shaft of the servo motor 132 and the rotating shaft 131 and the scroll shaft 134 can realize the rapid retraction of the spring. This helps to improve production efficiency and processing speed.

[0025] There are two rotating shafts 131, which are respectively arranged on both sides of the mounting plate 120, and the outer sides of the two rotating shafts 131 are respectively sleeved with gears 135, and the outer sides of the two gears 135 are sleeved with racks 140, and the outer sides of the racks 140 are connected with connecting blocks 141, which are slidably connected to the bottom of the transport plate 122, and the spiral spring 124 is connected to the side of the transport plate 122. The stability of the device can be ensured by the sliding connection at the bottom of the transport plate 122 and the side connection of the spiral spring 124. This connection method helps prevent the transport plate 122 from shaking or shifting during transportation, thereby improving the stability of the device and reducing product damage caused by unstable transportation.

[0026] In the present embodiment: by providing a scroll spring 124, when a fault occurs, the scroll spring 124 drives the scroll shaft 134 to rotate, so that the material transport plate 122 is pulled back. Pulling back the material transport plate 122 quickly can reduce the damage to mechanical components that may occur during the fault, reduce maintenance costs and maintenance time, and automatic resetting can also improve the stability and reliability of the production line, reduce the impact of human errors, and ensure that the production and transportation process of PCBs is smoother and more controllable.

[0027] Embodiment 2: This embodiment is intended to solve the problem of insufficient power of the spiral spring 124 when pulling the material transport plate 122. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-5A servo motor 132 is also installed on the side of the mounting plate 120. The servo motor 132 is configured as a dual-axis motor. When the motor is started, it drives the rotating shaft 131 and the gear 135 on the side of the rotating shaft 131 to rotate. The gear 135 is meshed with the rack 140 for transmission. The motor is in normal operation. The torsional force of the motor prevents the volute spring 124 from rebounding. When a fault occurs, the motor does not run, and the volute spring 124 drives the volute shaft 134 to rotate and drives the servo motor 132 to rotate and retract the transport plate 122.

[0028] In this embodiment, by setting a dual-shaft motor, when the volute spring 124 is retracted, the motor output shaft is driven to rotate, and the output shaft at the other end of the motor drives the gear 135 and the rack 140 to retract. The output shaft of the motor drives the gear 135 and the rack 140 to retract, so that a larger force output can be achieved to retract the volute spring 124. In this way, the spring can be retracted quickly and forcefully, thereby improving the retraction efficiency.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
