[0022] like Figures 1-4As shown, this utility model embodiment provides a transfer vehicle for the exposure-development process, including: a vehicle body 1, the vehicle body 1 including an outer shell and a sealing door 2, the sealing door 2 being disposed on one side of the outer shell, together forming the vehicle body 1 having a closed cavity; an adjustable printed circuit board storage platform is provided in the inner cavity of the vehicle body 1, the adjustable printed circuit board storage platform including at least one partition 6, and several first slots for horizontally fixing the partition 6 are longitudinally arranged on the relative inner walls of the vehicle body 1, so that the height of the partition 6 can be adjusted by placing the partition 6 in the first slots at different heights; several second slots with adjustable width are provided on the partition 6 for fixing and storing printed circuit boards of different sizes; the vehicle body 1 also includes: The light source system 7 is used to output a yellow light source when a printed circuit board is stored in the vehicle body 1, and to output a white light source in a clean state; The constant temperature and humidity control system 8 is used to maintain the temperature and humidity of the interior environment of the vehicle body 1 within a set range. An anti-misoperation self-locking system is connected to the sealing door 2 and is used to automatically lock the sealing door after the printed circuit board is placed in the vehicle body 1; An alarm system 5 is installed on the top of the vehicle body 1 and is used to trigger an audible and visual alarm when the printed circuit board is stored for a period exceeding a preset process time.

[0023] In some embodiments, the partition 6 has a plurality of fixing slots, and fixing rails are provided on the fixing slots to adjust the width of the second slot by inserting the fixing rails into different fixing slots.

[0024] In this embodiment, the width of the partition slot for storing printed circuit boards to be processed can be adjusted to accommodate printed circuit boards of various thicknesses; the height of the partition for storing printed circuit boards to be processed can be adjusted vertically to accommodate printed circuit boards of various sizes.

[0025] Preferably, the fixing groove and the fixing rail are fitted together by a mortise and tenon structure.

[0026] This utility model embodiment specifically provides a fixture for the exposure-development process, used during the transfer and waiting of printed circuit board patterns in the exposure and development processes. It includes a light source system, a temperature and humidity setting system, a light-proof sealing ring, a storage area for the printed circuit boards awaiting processing, and a movable trolley system. The exposed printed circuit boards are placed on two partitions within the fixture, and the output light source and temperature / humidity are adjusted according to the requirements of the dry film. This allows the printed circuit boards to be moved from the exposure stage to the development stage, ensuring the light source and temperature / humidity requirements of the dry film are met during the waiting process.

[0027] Specifically, the light source system outputs a yellow light source of appropriate intensity or a white light source when cleaning the tooling, depending on the processing requirements of the inner and outer dry film layers of the printed circuit board. In this embodiment, the dual-light source system provides a yellow light source to protect the dry film of the printed circuit board when there are boards being processed, and a white light source for easy cleaning when there are no boards being processed.

[0028] Specifically, the temperature and humidity setting system automatically adjusts the temperature and humidity inside the tooling according to the processing requirements of the inner and outer layers of the printed circuit board and the process setting value, so as to maintain the temperature and humidity inside the tooling at the optimal state of the dry film.

[0029] Specifically, the adjustable printed circuit board storage platform can adjust the partition height and slot width according to the size of the printed circuit board to be processed, making it suitable for printed circuit boards of various sizes. The platform is hollow to facilitate the circulation of air from top to bottom and to facilitate the control of constant temperature and humidity.

[0030] Specifically, the self-locking system for preventing accidental operation has a self-locking function on the door storing printed circuit boards. Once printed circuit boards are stored inside, the door cannot be opened arbitrarily; a password must be entered to open it. This prevents operators from accidentally opening the sealed door, which could cause the dry film on the printed circuit boards to degrade upon exposure to visible light, resulting in the scrapping of subsequent printed circuit boards.

[0031] Specifically, the required process time can be set inside the transfer vehicle. The alarm system is used to start timing after the printed circuit board is placed in the transfer vehicle. If the time exceeds the required process time, an alarm will be triggered by an alarm light and sound.

[0032] To facilitate the movement of the transport vehicle, in some embodiments, a handle 3 is provided on one side of the housing, and a wheel system 4 is provided at the bottom of the housing.

[0033] For ease of control, in some embodiments, a control panel 9 is provided on the sealed door 2, and the control panel 9 is connected to the light source system 7, the constant temperature and humidity control system 8, the anti-misoperation self-locking system and the alarm system 5 respectively.

[0034] In some embodiments, the vehicle body 1 is made of 304 stainless steel or acid and alkali resistant materials.

[0035] In some embodiments, the partition 6 of the adjustable printed circuit board storage platform has a hollow structure to facilitate the circulation of air from top to bottom and to facilitate the control of constant temperature and humidity.

[0036] In some embodiments, the temperature and humidity control requirements inside the transmission vehicle are ±3%RH and ±1℃.

[0037] In some embodiments, the anti-misoperation self-locking system includes a password switch device disposed on the sealed door. In this embodiment, the door storing the printed circuit board has a self-locking function; once the printed circuit board is stored inside, the door cannot be opened arbitrarily and a password must be entered to open it. This prevents operators from accidentally opening the sealed door, which could cause the dry film on the printed circuit board to degrade upon exposure to visible light, resulting in the scrapping of subsequent printed circuit boards.

[0038] In some embodiments, a battery module is also provided inside the vehicle body 1 for supplying power to the constant temperature and humidity control system 8 and the light source system 7 during movement.

[0039] In some embodiments, the alarm system 5 includes a timer controller and an audible and visual alarm. The transfer vehicle in this embodiment can be set with a required process time. Timing begins after the printed circuit board is placed in the transfer vehicle, and an alarm is triggered by both an alarm light and a sound if the required process time is exceeded.

[0040] This embodiment features a password-protected door opening mechanism for storing outsourced printed circuit boards and an audible / visual alarm device for exceeding processing time limits, maximizing the protection against the scrapping of printed circuit boards due to operator error.

[0041] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
