[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] refer to Figure 1-4 This utility model provides the following two technical solutions:

[0022] First embodiment: An automatic loading and unloading machine for an exposure machine includes an exposure machine body 1. The exposure machine body 1 is connected to a storage and retrieval component for loading and unloading circuit boards. The storage and retrieval component includes: an adjustment component 2, which is installed on the left side of the exposure machine body 1 for limiting and adjusting the loading and unloading of circuit boards. The adjustment component 2 includes a loading component 21. The loading component 21 includes a support frame 213 slidably connected to the outer left end of the exposure machine body 1. A stop block 215 for preventing detachment is vertically slidably connected to the middle left side of the support frame 213. A limiting component 22 for horizontal limiting of the circuit board is connected to the support frame 213. The limiting component 22 includes two sets of limiting frames 222 for limiting. The support frame 213 is also connected to a unloading component 23 for unloading the circuit board. A guide plate 24 is inclinedly arranged on the left side of the exposure machine body 1 near the support frame 213. The top of the guide plate 24 is flush with the upper surface of the support frame 213.

[0023] The robotic arm assembly 3 is installed at the rear left side of the exposure machine body 1 for storing circuit boards; the loading component 21 also includes a one-way screw 212 rotatably connected to the lower left side of the outer side of the exposure machine body 1. The one-way screw 212 is rotatably connected to the support frame 213. The middle of the support frame 213 is provided with a sliding groove 214 along the Y-axis, which is slidably connected to two sets of limit frames 222 respectively. A first motor 211 for driving the one-way screw 212 is installed on the outer side of the exposure machine body 1. An electric push rod 216 for adjusting the height of the stop block 215 is provided at the lower left side of the support frame 213. The left side of the exposure machine body 1 is provided with an inlet groove for circuit board inlet corresponding to the loading component 21, the limit component 22, and the unloading component 23.

[0024] The limiting component 22 also includes a bidirectional screw 221 rotatably connected to the lower side of the support frame 213 along the Y-axis and used to adjust the distance between the two sets of limiting frames 222. A second motor 223 for driving the bidirectional screw 221 is installed at the bottom of the support frame 213. Each of the two sets of limiting frames 222 is provided with a guide groove 224 for guiding the unloading component 23. The output end of the second motor 223 is coaxially fixedly connected to the bidirectional screw 221. The guide groove 224 is a square groove. The upper surface of the support frame 213 is perpendicular to the limiting frame 222. Fitting; the unloading component 23 includes slide bars 232 that are slidably connected to two sets of limiting frames 222 respectively. The support frame 213 is provided with two sets of electric slide rails 231 along the X-axis for adjusting the slide bars 232. The electric slide rails 231 are slidably connected to the slide bars 232. The middle part of the slide bar 232 is provided near the upper surface of the support frame 213 for limiting the circuit board along the X-axis and unloading. The support frame 213 and the guide plate 24 are both provided with sponge pads. The first motor 211 and the second motor 223 are both servo motors.

[0025] The bidirectional screw 221, the second motor 223, the two sets of limit frames 222, the electric slide rail 231, the slide bar 232, the toggle block 233, and the stop block 215, without affecting each other, limit the circuit board of the corresponding size on the support frame 213 along the X and Y axes respectively. After the circuit board is processed, the electric push rod 216 adjusts the height of the stop block 215. At this time, the circuit board is unloaded through the electric slide rail 231, the slide bar 232, and the toggle block 233.

[0026] The main difference between the second implementation method and the first implementation method is that:

[0027] The output end of the first motor 211 is coaxially and fixedly connected to the one-way screw 212. The one-way screw 212 is set on the outside of the exposure machine body 1 along the X-axis. The extended end of the electric push rod 216 is fixedly connected to the stop block 215. The electric push rod 216 provides support for the stop block 215, which facilitates the stop block 215 to cooperate with the dial block 233 to limit the circuit board. After the circuit board is processed, the electric push rod 216 drives the stop block 215 to retract, which facilitates the subsequent unloading of the circuit board.

[0028] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0029] In use, the user places a recycling bin under the guide plate 24, and uses the robotic arm assembly 3 to place the circuit board to be processed onto the support frame 213. The electric slide rail 231 drives the slide bar 232 and the lever 233 to move horizontally. The slide bar 232 slides along the guide grooves 224 inside the two sets of limit frames 222. After the lever 233 contacts the circuit board, it is pushed to the left, so that the left side of the circuit board contacts the stop block 215. The second motor 223 is then started. The second motor 223 drives the two sets of limit frames 222 to slide along the slide grooves 214 via the bidirectional screw 221. After the two sets of limit frames 222 contact the front and rear sides of the circuit board respectively, the second motor 223 is turned off, and the first motor 211 is started. The first motor 211 drives the circuit board via the unidirectional screw 212. The moving support frame 213, stop block 215, electric push rod 216, limit member 22, and circuit board are introduced into the exposure machine body 1. The circuit board is processed by the exposure machine body 1. The exposure machine body 1, electric slide rail 231, and robotic arm assembly 3 are all existing technologies, so their internal structure and working principle will not be described in detail. After resetting each link, the height of the stop block 215 is adjusted by the electric push rod 216 so that the top of the stop block 215 is flush with the bottom of the circuit board. The horizontal position of the slide bar 232 and the toggle block 233 is adjusted so that the toggle block 233 moves the circuit board toward the exposure machine body 1. Then the circuit board slides into the recycling box through the guide plate 24. A sponge pad is placed on the circuit board in the recycling box, and the above circuit board exposure machine loading and unloading operation is repeated.
