Description

Technical Field

[0001] This utility model relates to the field of exposure machine technology, and in particular to an exposure machine with a positioning structure. Background Technology

[0002] An exposure machine is a core piece of equipment in the printed circuit board manufacturing process. It is mainly used for pattern transfer processes. It uses high-intensity ultraviolet light as a light source to shine through a film (called a film or photomask) with a circuit pattern onto a circuit board substrate coated with photosensitive material. The photosensitive material exposed to ultraviolet light undergoes a chemical reaction (polymerization or decomposition), thereby accurately "copying" the circuit pattern on the film onto the circuit board, preparing it for subsequent etching or electroplating processes.

[0003] In existing technology, operators need to cover the film onto the circuit board and attach it with stickers before feeding it into the exposure machine to complete the work. During this process, traditional exposure machines lack corresponding positioning mechanisms to restrain the film, causing the film to easily slip or fall off, which affects work efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an exposure machine with a positioning structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An exposure machine with a positioning structure includes a machine body, inside which a material platform is configured for feeding. The material platform has a groove in the middle for placing materials. Limiting grooves are opened on both sides of the inner wall of the groove. A limiting rod is installed between adjacent limiting grooves by a slider. A pair of limiting sleeves are symmetrically installed on the limiting rods. A pressure plate is provided on one side of the limiting sleeve.

[0007] The inner wall of the limiting sleeve is provided with a protruding limiting block, which is installed in a groove opened on the outer wall of the limiting rod.

[0008] The two ends of the limiting rod are rotatably connected to the slider, and a torsion spring is installed at the rotatable connection between the limiting rod and the slider.

[0009] Furthermore, in a preferred configuration, the slider achieves horizontal linear displacement via a limiting groove.

[0010] Furthermore, in a preferred configuration, the bottom wall of the pressure plate and the upper surface of the material platform are kept in parallel contact under natural conditions, and mutual compression contact is achieved through the pre-compression force of the torsion spring.

[0011] In addition, a preferred structure is that the limiting sleeve is hollow in the middle and is sleeved on the outer wall of the limiting rod, and the inner wall of the limiting sleeve is provided with a rubber bushing, which is in extrusion contact with the outer wall of the limiting rod.

[0012] Furthermore, in a preferred configuration, the limiting sleeve achieves horizontal linear displacement via a sliding groove.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, the material platform is equipped with a pair of freely movable limiting rods, and the limiting rods are equipped with a pair of horizontally adjustable limiting sleeves. The limiting sleeves press the four corners of the substrate with pressure plates to ensure the stability of the substrate during feeding and unloading, and to ensure that the substrate is stably covered on the circuit board. Compared with traditional devices that require manual application of stickers for fixation, this pressing method is simple to operate and accurate in positioning, which can effectively prevent the substrate from shifting during subsequent processing and ensure processing quality.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 An exposure machine with a positioning structure includes a body 1. The body 1 is equipped with a material platform 11 for feeding materials. The material platform 11 has a groove in the middle for placing materials. Limiting grooves 12 are opened on both sides of the inner wall of the groove. A limiting rod 2 is installed between adjacent limiting grooves 12 by a slider 4. A pair of limiting sleeves 3 are symmetrically installed on the limiting rod 2. A pressure plate 31 is provided on one side of the limiting sleeve 3.

[0022] The inner wall of the limiting sleeve 3 is provided with a protruding limiting block 32. The limiting block 32 is installed in the sliding groove 21 opened on the outer wall of the limiting rod 2. The limiting sleeve 3 moves horizontally and linearly on the sliding groove 21 through the limiting block 32.

[0023] The two ends of the limiting rod 2 are rotatably connected to the slider 4. A torsion spring 5 is installed at the rotatable connection between the limiting rod 2 and the slider 4. In its natural state, the torsion spring 5 applies a force to the pressure plate 31 through its torsional force, driving the pressure plate 31 to rotate toward the material platform 11 to achieve a contact state.

[0024] The slider 4 achieves horizontal linear displacement through the limiting groove 12.

[0025] In its natural state, the bottom wall of the pressure plate 31 and the upper surface of the material platform 11 are in parallel contact, and they are pressed together by the pre-compression force of the torsion spring 5.

[0026] The limiting sleeve 3 is hollow in the middle and is fitted onto the outer wall of the limiting rod 2. The inner wall of the limiting sleeve 3 is provided with a rubber bushing 33, which is in contact with the outer wall of the limiting rod 2.

[0027] The limiting sleeve 3 achieves horizontal linear displacement through the sliding groove 21.

[0028] In this embodiment, the circuit board to be processed is placed on the material platform 11, and the corresponding substrate is covered on the surface of the circuit board to complete the pre-alignment operation. Then, the corresponding position limit rod 2 is moved to rotate around the sliders 4 on both sides, so as to drive the two limit sleeves 3 installed on the limit rod 2 and the pressure plate 31 connected thereto to lift up synchronously, thereby causing the pressure plate 31 to disengage from the material platform 11.

[0029] Next, the moving limit rod 2 moves horizontally along the limiting groove 12 inside the material platform 11 via the sliders 4 on both sides until the pressure plate 31 moves to the two corners on the upper side of the bottom sheet. Then the limit rod 2 is released, and under the pre-tightening force of the torsion spring 5, the pressure plate 31 presses down again and presses the two corners of the bottom sheet tightly and fixed.

[0030] Similarly, following the same operating procedure, move and position the limiting rod 2 on the other side so that its pressure plate 31 presses the remaining two corners of the substrate, ultimately achieving full pressing and fixing of all four corners of the substrate.

[0031] Compared to traditional devices that require manual application of stickers for fixation, this clamping method is simple to operate and accurate in positioning, effectively preventing the film from shifting during subsequent processing.

[0032] In practical applications, the inner wall of the limiting sleeve 3 is provided with a rubber bushing 33. When the limiting sleeve 3 moves along the outer wall of the limiting rod 2, the rubber bushing 3 provides a continuous radial damping force, which effectively ensures the stability and controllability of the movement of the limiting sleeve 3 and avoids unexpected free sliding.

[0033] In addition, under natural conditions, the pressure plate 31 maintains a pressing contact with the surface of the material platform 11 under the action of the torsion spring 5. The static friction generated between the two can effectively suppress the free displacement of the limit rod 2 along the limit groove 12, ensuring the stability of the pressing mechanism.

[0034] Furthermore, the limiting sleeve 3 is provided with a limiting block 32 inside, which forms a concave-convex mating mechanism with the sliding groove 21 opened on the outer wall of the limiting rod 2.

[0035] It should be noted that the machine body 1, i.e. the exposure machine body, and the material platform 11 are standard material feeding configurations of the exposure machine body. The specific internal structure and operating principle of the exposure machine body that have not been explained in detail above are common knowledge to those skilled in the art.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
