AI Technical Summary
In existing automated production equipment, the positioning mechanism of the movable positioning pin has problems such as high cost, large space and poor reliability. Especially during the rolling process of the substrate film, the up and down movement of the positioning pin requires multiple switching signals and cylinders, resulting in increased equipment costs and potential collision risks.
The powerless linkage positioning mechanism is adopted to drive the lifting and lowering of the linkage plate and the positioning pin through the movement of the press roller, and the automatic rise and fall of the positioning pin is achieved by using the elastic reset component, which simplifies the structure and reduces the dependence on the power source.
The automatic avoidance of the positioning pin is realized without the need for an additional power source, which reduces equipment costs, reduces space occupation, and improves reliability and assembly convenience.

Abstract
Description
Technical Field
[0001] The present invention relates to a positioning mechanism, and more particularly to a power-free linkage positioning mechanism and a film laminating and rolling device. Background Art
[0002] With the rise of automation and intelligence nowadays, all walks of life are constantly seeking to replace the traditional manual labor production mode with non-standard automation equipment. In the automation industry of electricians and electronics, the substrate is an indispensable and important component. During the production process, there is a process of film laminating and rolling, and the substrate needs to be positioned throughout this process. Please refer to Figure 1 as shown Figure 1 which is a schematic diagram of the positioned substrate in the electrician and electronics industry in the prior art. However, when rolling to the relative position of the positioning pin, the positioning pin needs to temporarily fall below the substrate without affecting the rolling effect.
[0003] In the existing automated production equipment, for occasions where such movable positioning pins are required, the common mechanism is to connect a cylinder below the positioning pin. When the rolling fixture is about to reach this position, the switch sends a signal, and the cylinder drives the positioning pin to move downward in advance to avoid collision. After the pressure roller moves away, the switch sends another signal, and the positioning pin extends again. Every time the pressure roller passes by a pin, the cylinder at this position needs to drive the positioning pin at this position to make corresponding up and down evasions, and so on. Obviously, in this mechanism, in order to enable the positioning pin to make up and down evasion movements, two switch signals, one cylinder, and its supporting fixtures and air valves, etc. need to be added at each positioning pin position.
[0004] Therefore, the positioning mechanisms that currently require movable positioning pins have the following disadvantages:
[0005] 1) Two switches, a set of cylinder air valves, etc. are equipped at each positioning pin position, which increases the cost of the equipment significantly;
[0006] 2) The possible failure of the switch signal may cause the pressure roller and the positioning pin to collide directly, resulting in danger;
[0007] 3) Each positioning pin must be equipped with a cylinder as the power source for rising and falling. Even a small cylinder also needs to occupy a certain space, which is difficult to arrange in occasions with limited space. Summary of the Invention
[0008] The purpose of the present invention is to provide a power-free linkage positioning mechanism to solve the problems of high cost, large space occupation, and poor reliability existing in the positioning mechanisms that require movable positioning pins in the prior art.
[0009] Another object of the present invention is to provide a film laminating and rolling device to solve the problems of high cost, large occupied space and poor reliability existing in the substrate film laminating and rolling mechanism in the prior art.
[0010] To achieve this object, the present invention adopts the following technical solutions:
[0011] A non-powered linkage positioning mechanism, which includes,
[0012] A fixing plate, configured to serve as the assembly basis for the entire positioning mechanism,
[0013] A linkage plate, which is assembled above the fixing plate in a liftable manner. The linkage plate includes an unlocking surface at the upper part and an inner side surface close to the sheet-like part. An elastic reset component is arranged between the fixing plate and the linkage plate.
[0014] A positioning pin, fixed on the linkage plate and located inside the inner side surface. The projection of the positioning end of the positioning pin on the inner side surface is within the contour range of the inner side surface.
[0015] When the pressing roller passes through the unlocking surface, it presses the linkage plate to move downward against the elastic force of the elastic reset component. The linkage plate drives the positioning pin to descend, and the positioning pin exits the positioning state. After the pressing roller leaves the unlocking surface, the linkage plate drives the positioning pin to rise through the elastic force of the elastic reset component, and the positioning pin is in the positioning state.
[0016] Further, the unlocking surface includes a flat surface, and a downward-extending slope surface is symmetrically arranged at both ends of the flat surface. The connection between the two slope surfaces and the flat surface is transitioned by an arc.
[0017] Further, blind holes are correspondingly arranged on the end surface of the fixing plate and the bottom surface of the linkage plate. The elastic reset component adopts a spiral spring. One end of the spiral spring is assembled in the blind hole of the fixing plate, and the other end is assembled in the blind hole of the linkage plate.
[0018] Further, a guiding shaft extending downward is fixed on the bottom surface of the linkage plate. A first guiding hole is opened on the fixing plate corresponding to the guiding shaft, and the guiding shaft is arranged through the first guiding hole.
[0019] Further, a connecting plate extends from the inner side surface of the linkage plate to the side close to the sheet-like part. A through hole is opened on the connecting plate. A second guiding hole is opened on the fixing plate corresponding to the through hole. The positioning end of the positioning pin is arranged through the through hole, and the other end is arranged through the second guiding hole.
[0020] Furthermore, a limiting boss located below the connecting plate is provided on the positioning pin, a pressing plate is installed on the bottom surface of the linkage plate, and the pressing plate presses the limiting boss to fix the positioning pin to the connecting plate.
[0021] Furthermore, linear bearings are provided in both the first guiding hole and the second guiding hole.
[0022] Furthermore, two positioning pins are provided, and the two positioning pins are assembled on the connecting plate at intervals.
[0023] A film laminating and rolling device includes a rolling platform and a pressing roller. Among them, a plurality of sheet parts are placed on the rolling platform. Positioning holes are provided at the four corners of the sheet parts, and the above-mentioned non-powered linkage positioning mechanism is provided on both sides of the adjacent connection of two sheet parts on the rolling platform. The positioning pins of the non-powered linkage positioning mechanism extend out of the positioning holes, and the linkage plate is located outside the sheet parts.
[0024] Furthermore, the two positioning pins of the same non-powered linkage positioning mechanism respectively position two adjacent sheet parts.
[0025] The beneficial effects of the present invention are as follows. Compared with the prior art, the non-powered linkage positioning mechanism and the film laminating and rolling device utilize the particularity of the rolling process itself to realize the automatic rising and falling avoidance action of the positioning pins without separately setting power. It not only has a simple structure and ingenious design, but also reduces costs, occupies a small space, is convenient for assembly, and has high performance and reliability.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0036] Please refer to Figures 2 to 8As shown in the figure, in this embodiment, a film laminating and rolling device includes a rolling platform and a pressure roller. A number of substrates 1 are placed on the rolling platform. Positioning holes are provided at the four corners of the substrate 1. And on both sides of the joint of two adjacent substrates 1 on the rolling platform, a non-powered linkage positioning mechanism is provided. The non-powered linkage positioning mechanism includes a fixing plate 2, a linkage plate 3 and two positioning pins 4. The fixing plate 2 serves as the assembly basis of the entire positioning mechanism and is fixed on the rolling platform. The linkage plate 3 is assembled above the fixing plate 1 in a liftable manner. Two guiding shafts 5 which are arranged at intervals and extend downward are fixed on the bottom surface of the linkage plate 3. Two first guiding holes are provided on the fixing plate 1 corresponding to the guiding shafts 5. First linear bearings 6 are installed in both of the two first guiding holes. The bottom ends of the guiding shafts 5 pass through the first linear bearings 6. On the outer sides of the two guiding shafts 5, a pair of blind holes are correspondingly provided on the end face of the fixing plate 2 and the bottom surface of the linkage plate 3. Helical springs 7 which provide the restoring elastic force for the linkage plate 3 are installed in both of the two pairs of blind holes. One end of the helical spring 7 is assembled in the blind hole of the fixing plate 2, and the other end is assembled in the blind hole of the linkage plate 3.
[0037] The end face of the linkage plate 3 is an unlocking surface. The unlocking surface includes a flat straight surface 8. At both ends of the flat straight surface 8, a sloping surface 9 extending downward is symmetrically provided. The joints of the two sloping surfaces 9 and the flat straight surface 8 are transitioned through an arc 10. The inner side surface of the linkage plate 3 extends toward the side close to the substrate 1 to form a connecting plate 11. Two through holes are provided on the connecting plate 11 at intervals. Two second guiding holes are provided on the fixing plate 2 corresponding to the through holes. Second linear bearings 12 are installed in both of the two second guiding holes. The top ends of the two positioning pins 4 pass through the through holes, and the other ends pass through the second linear bearings 12. The projections of the positioning ends of the two positioning pins 4 on the inner side surface of the linkage plate 3 are located within the contour range of the inner side surface. Limiting bosses 13 located below the connecting plate 11 are provided on both of the two positioning pins 4. A pressing plate 14 located between the two limiting bosses 13 is installed on the bottom surface of the linkage plate 3. The pressing plate 14 presses the two limiting bosses 13 to fix the two positioning pins 4 on the connecting plate 11.
[0038] Under the guiding action of the four linear bearings, it is ensured that the positioning of the positioning pin 4 is accurate and reliable. With the addition of the spring force of the two helical springs 7, it is ensured that the linkage plate 3 always maintains a certain distance from the fixing plate 2 without the action of a large external force. That is to say, under normal circumstances, the positioning pin 4 plays the role of a normal positioning pin.
[0039] The dimensions of the upper halves of the two positioning pins 4 are all included within the contour range of the inner side surface of the linkage plate 3. That is to say, in this direction, when a pressure roller with sufficient length horizontally moves left and right to press on the linkage plate 3, when it descends, it will not touch the positioning pin 4; when the pressure roller moves and encounters the inclined surface of the linkage plate 3, a downward pressing force is generated to overcome the rebounding force of the helical spring 7. Under the guiding action of the linear bearing, the linkage plate 3 drives the positioning pin 4 to move downward. After the positioning pin 4 descends, the substrate 1 to be positioned is temporarily out of the positioning state; when the pressure roller moves and leaves the range of the linkage plate 3, under the action of the spring force, the linkage plate 3 drives the positioning pin 4 to rise, and the positioning pin 4 resumes positioning of the product.
[0040] Generally, the substrate 1 is positioned by four positioning pins. Each time two positioning pins 4 are out of the positioning state for a very short time, it does not affect the product positioning; and during the entire operation process, the pressure roller always maintains a pressing state on the product, ensuring the continuity of pressing.
[0041] The above embodiments only illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above examples. Without departing from the spirit and scope of the present invention, there are various changes and alterations to the present invention, and these changes and alterations all fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
