Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive application for reinforcing steel sheets, and more particularly to an adhesive application and alignment mechanism for reinforcing steel sheets. Background Technology
[0002] In the field of electronic component manufacturing, reinforcing steel sheets are typically attached to specific areas of flexible printed circuit boards (FPCs) or rigid-flex boards using a hot-pressing process to enhance local mechanical strength and improve soldering reliability. This process usually involves a continuously conveyed conveyor belt carrying the reinforcing steel sheet, which is then bonded using conductive adhesive during hot pressing. However, in actual production, the conveyor belt is susceptible to slight deformation due to factors such as heat radiation, tension fluctuations, and mechanical vibrations from the hot-pressing equipment, leading to positional drift. Inaccurate adhesive alignment can cause deviations between the reinforcing steel sheet and its intended position, resulting in uneven adhesive layer distribution, reduced bonding strength, or poor electrical connections, severely impacting product yield and long-term reliability. In existing technologies, fixed positioning fixtures or mechanical stops are often used for coarse positioning of the strip, followed by fine-tuning through a vision system or manual adjustments to achieve precise alignment. However, these methods suffer from slow response times, especially in fast and continuous production environments, where strip deformation caused by thermal expansion and tension changes is difficult to fully compensate for using static fixtures. Utility Model Content
[0003] In view of this, the purpose of this utility model is to propose a reinforcing steel sheet adhesive alignment mechanism to solve the technical problems in the prior art.
[0004] To achieve the above objectives, this utility model provides a reinforcing steel sheet adhesive application and alignment mechanism, including an upper pressing mold, a lower pressing mold, and an electric cylinder for driving the upper pressing mold. The mechanism further includes: Symmetrical grooves are provided at the bottom of the upper mold; A lower groove is provided on the top of the lower die and located between two upper grooves. Lower positioning fixtures are symmetrically slidably mounted on the surface of the lower die on both sides of the lower groove. A push plate is fixed to the bottom of the lower positioning fixture, and the lower end of the push plate extends to the side of the lower groove. A connecting block is symmetrically fixed to the end of the lower die. The connecting block has a through hole, and a pressure rod is provided on the through hole. One end of the pressure rod is detachably connected to the lower positioning fixture. A spring is fitted onto the pressure rod, with its two ends connected to the end of the pressure rod and the connecting block, respectively. A symmetrically detachable pusher is installed at the end of the upper die, with the pusher opposite the other end of the pressure rod; When the upper die is driven to descend by the electric cylinder, the pusher pushes the pressure rod to move, so that the two pressure rods drive the corresponding lower positioning fixture and push plate to move towards each other and center the material strip.
[0005] Preferably, the surface of the lower die is symmetrically provided with grooves, and a slider is slidably installed in the groove. The lower positioning fixture is detachably connected to the slider by bolts.
[0006] Preferably, the top wall of the upper groove is provided with an installation groove, and an upper positioning fixture is detachably installed in the installation groove by bolts. The upper positioning fixture is provided with multiple positioning pins at equal intervals.
[0007] Preferably, the lower positioning fixture has multiple positioning holes equidistantly spaced on its surface corresponding to the positioning pins.
[0008] Preferably, the bottom of the positioning pin has a tapered structure that tapers from top to bottom.
[0009] Preferably, the bottom of the lower groove has several through holes, which correspond vertically to the positioning pins.
[0010] Preferably, the pushing member includes a mounting block that is bolted to the upper mold and a pushing plate located at the bottom of the mounting block, the bottom of the pushing plate having an inclined surface that slopes downward toward the pressure rod.
[0011] Preferably, one end of the pressure rod corresponding to the pusher is provided with a ball, the diameter of which is larger than the cross-sectional diameter of the pressure rod, and the ball is matched with the inclined surface of the pusher plate.
[0012] Preferably, the inner wall of the connecting block through hole is provided with multiple circumferentially distributed grooves, and a ball bearing is rotatably installed in the groove, with the surface of the ball bearing in contact with the outer wall of the pressure rod.
[0013] The beneficial effects of this utility model are as follows: The reinforcing steel sheet adhesive application and alignment mechanism of this utility model, through the setting of components such as upper pressure mold, push plate and pusher, etc., during the descent of the upper pressure mold, causes the lower positioning fixture to drive the push plate to move in opposite directions to complete the centering of the material strip. After centering, the positioning pin continues to descend, and the positioning pin is inserted into the positioning hole on the material strip through the positioning hole on the lower positioning fixture to reposition the material strip, realizing dynamic compensation, thereby further improving the accuracy of reinforcing steel sheet adhesive application and increasing the yield. With the installation of components such as the upper positioning fixture, lower positioning fixture, and slider, when the standard needs to be changed, the bolts can be loosened, the upper and lower positioning fixtures can be replaced, and another module fixture corresponding to the new hole spacing can be installed. This ensures the accuracy of each fixture and further facilitates fixture replacement. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0019] The first aspect of this utility model proposes a reinforcing steel sheet adhesive-fitting and alignment mechanism, such as... Figure 1-6 As shown, the mechanism includes an upper die 1, a lower die 2, and an electric cylinder 3 for driving the upper die 1. The mechanism also includes: The upper groove 101 is symmetrically arranged at the bottom of the upper mold 1; A lower groove 201 is located at the top of the lower mold 2 and between the two upper grooves 101. Lower positioning fixtures 4 are symmetrically slidably mounted on the surface of the lower mold 2 on both sides of the lower groove 201. A push plate 6 is fixed to the bottom of the lower positioning fixture 4, and the lower end of the push plate 6 extends to the side of the lower groove 201. A connecting block 7 is symmetrically fixed to the end of the lower die 2. The connecting block 7 has a through hole, and a pressure rod 8 is provided on the through hole. One end of the pressure rod 8 is detachably connected to the lower positioning fixture 4. A spring 9 is fitted onto the pressure rod 8, with its two ends connected to the end of the pressure rod 8 and the connecting block 7, respectively. It should be noted that there are two sets of connecting blocks 7, which are symmetrically arranged at both ends of the lower die 2. This allows for simultaneous alignment of the two ends of the material strip in the hot press die during the alignment of the material strip, thereby improving the accuracy of the material strip alignment. A pusher 10 is symmetrically and detachably installed at one end of the upper die 1, and the pusher 10 is opposite to the other end of the pressure rod 8; When the electric cylinder 3 drives the upper die 1 to descend, the pusher 10 pushes the pressure rod 8 to move, so that the two pressure rods 8 drive the corresponding lower positioning fixture 4 and push plate 6 to move towards each other and center the material strip.
[0020] In the process of hot pressing and bonding the reinforcing steel sheet with the continuously conveyed strip, when the electric cylinder 3 drives the upper die 1 to move down and the lower die 2 to approach the reinforcing steel sheet for hot pressing and bonding, in order to avoid the strip deformation caused by thermal expansion and tension changes, which would lead to positional drift and affect the accuracy of hot pressing, the bottom of the symmetrical pushers 10 at both ends of the upper die 1 is first pressed against the corresponding pressure rods 8, so that the pressure rods 8 drive the lower positioning fixture 4 to slide on the surface of the lower die 2, thereby driving the push plates 6 to move towards each other and contact and push the strip. After the lower positioning fixture 4 moves to the limit position in the slide groove 202 through the slider 203, the two symmetrical push plates 6 complete the centering of the strip.
[0021] In this embodiment: the surface of the lower die 2 is symmetrically provided with grooves 202, and a slider 203 is slidably installed in the grooves 202. The lower positioning fixture 4 is detachably connected to the slider 203 by bolts.
[0022] In this embodiment: the top wall of the upper groove 101 is provided with a mounting groove, and the upper positioning fixture 5 is detachably installed in the mounting groove by bolts. Multiple positioning pins 501 are provided at equal intervals on the upper positioning fixture 5. Since the upper positioning fixture 5 and the lower positioning fixture 4 are both detachably installed on the corresponding upper mold 1 and slider 203 by bolts, when it is necessary to change the standard, the bolts can be loosened, the positioning pins 501 and the lower positioning fixture 4 can be replaced, and another module fixture corresponding to the new hole spacing can be installed, which makes it easy to ensure the accuracy of each fixture itself.
[0023] In this embodiment, the lower positioning fixture 4 has multiple positioning holes 401 equidistantly spaced on its surface corresponding to the positioning pin 501. After the two lower positioning fixtures 4 move to their extreme positions relative to each other, the positioning pin 501 is located directly above the corresponding positioning hole 401. When the positioning pin 501 descends, it can smoothly pass through the positioning hole 401 and be inserted into the positioning hole on the material strip for positioning.
[0024] In this embodiment, the bottom of the positioning pin 501 is a tapered structure that tapers from top to bottom.
[0025] In the semi-automatic application of adhesive to reinforcing steel sheets, the positioning pin 501 can smoothly pass through the positioning hole 401 and be inserted into the positioning hole on the strip during its downward movement. To further increase the accuracy of strip positioning, during the descent of the upper die 1, the positioning pin 501 at the bottom of the upper positioning fixture 5 on the upper die 1 is positioned directly below the positioning hole 401 on the lower positioning fixture 4 after the lower positioning fixture 4 moves to the limit position of the slide groove 202. As the positioning pin 501 continues to descend, it is inserted into the positioning hole on the strip through the positioning hole 401, thus repositioning the strip and achieving dynamic compensation. This further improves the accuracy of adhesive application to the reinforcing steel sheets and increases the yield rate.
[0026] In this embodiment, the bottom of the lower groove 201 has several through holes, which correspond vertically to the positioning pins 501. It should be noted that after the positioning pins 501 descend and pass through the positioning holes on the material strip, they extend into the through holes as they continue to descend, thus avoiding interference with the descent of the positioning pins 501.
[0027] In this embodiment, the pusher 10 includes a mounting block that is bolted to the upper mold 1 and a pusher plate located at the bottom of the mounting block. The bottom of the pusher plate has an inclined surface that slopes downward toward the pressure rod 8.
[0028] In this embodiment: a ball is provided at one end of the pressure rod 8 corresponding to the pusher 10. The diameter of the ball is larger than the cross-sectional diameter of the pressure rod 8, and the ball cooperates with the inclined surface of the pusher plate. By cooperating with the inclined surface at the bottom of the pusher 10, the contact area between the two is reduced and friction is reduced when the pusher 10 pushes the pressure rod 8 to move by pressing it from the bottom, so as to facilitate the movement of the pressure rod 8. When the bottom inclined surface of the pusher 10 presses against the ball at one end of the pressure rod 8 and pushes the pressure rod 8 closer to the material strip, when the ball at one end of the pressure rod 8 moves and contacts the bottom inclined surface of the pusher 10, the ball at one end of the pressure rod 8 presses against the vertical surface on one side of the pusher 10 as the pusher 10 continues to move downward, so as to keep the pusher plate 6 aligned with the material strip, so that the positioning pin 501 can be smoothly inserted into the positioning hole 401 during descent.
[0029] In this embodiment, the inner wall of the connecting block 7 through the hole is provided with multiple circumferentially distributed grooves, and ball bearings are rotatably installed in the grooves, with the surface of the ball bearings contacting the outer wall of the pressure rod 8. It should be noted that, during the movement of the pressure rod 8, the ball bearings on the inner wall of the connecting block 7 enable the pressure rod 8 to roll and contact within the inner wall of the connecting block 7, which further ensures the stability of the movement of the pressure rod 8.
