Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a positioning device for a screen-printed short-side positioning piece stacking and filling fixture. Background Technology

[0002] The most significant characteristic of a diffuser plate is its ability to cause substantial light interference. Regardless of the original light distribution curve, once light passes through the diffuser plate, the beam angle will change to 160-176°. Therefore, when viewed from the side, the surface of the light fixture appears hazy, which is the best proof that the beam angle is as large as 160-176°. The larger the beam angle, the lower the illuminance. Some diffusers can also filter light, preventing some wavelengths from passing through and causing color shift. If the surface is further treated with light interference (e.g., frosting, embossing), the light transmittance will be even lower due to the natural phenomena of geometric optics. Therefore, the substrate used to make diffusers should have the lowest possible refractive index to minimize light interference.

[0003] The following defects still exist in actual use:

[0004] 1) In the process of bonding the substrate film and the diffusion film to obtain the diffusion sheet, it is necessary to stack and fill the positioning according to the material edges of different diffusion plates. Moreover, the manual positioning of the substrate film and the diffusion film is not precise enough, which will inevitably produce air bubbles in the gap between the substrate film and the diffusion film. Due to the lack of precision in positioning, the positioning of the diffusion plate used for positioning in Zaolin Village is not convenient enough, and it is impossible to easily realize the function of unified upward or backward movement of multiple X-axis and Y-axis between the substrate film and the diffusion film.

[0005] 2) The efficiency of superposition and filling during the specified corner positioning and transfer process is poor, and there is no complete fixture to replace manual labor for rapid positioning of the screen printing edge during the positioning stage. At the same time, the transfer of the substrate film and diffusion film in the further positioning stage is relatively cumbersome. Since the positioning strips and filling films on the fixture are all single-layered, special attention needs to be paid to maintaining the positioning accuracy of the specific superposition and filling fixture in order to protect the screen during the lamination stage. Traditional positioning sheet superposition cannot guarantee the consistency of the height of the screen printing positioning strips and filling films. The consequence is that the positioning film structure of the filling and positioning is misaligned, which easily causes uneven edges of the film during the positioning process. If this is not resolved in time, hasty superposition will cause white edges of the filling film, which will seriously affect the yield. Summary of the Invention

[0006] The purpose of this invention is to provide a positioning device for screen-printed short-side positioning sheet superposition and filling fixture, so as to solve the problems mentioned in the background art.

[0029] As a preferred embodiment of the present invention: the bottom side of the transverse support plate is telescopically connected to the four corners of the transverse support plate via a telescopic end;

[0030] A transmission mechanism is provided at the rear end of the belt guide rod;

[0031] The transmission mechanism includes a drive bracket at one end of one of the multiple belt guide rods, and the drive bracket is supported by a two-part bracket structure.

[0032] As a preferred embodiment of the present invention: a limiting shaft seat is provided at the top center of the two halves of the bracket structure, a transmission roller is provided at the center of the limiting shaft seat, and a driven sleeve wheel is sleeved at the center of the shaft of the transmission roller through the center of the transmission sprocket, and the surface of the driven sleeve wheel is sleeved with one end of the track.

[0033] As a preferred embodiment of the present invention: the positioning strips and filling films of the fixture are all single-layered, and the filling films of the screen-printed positioning strips are protective mesh plates from top to bottom, and are positioned by the fixture through the subsequent stacking of filling strips.

[0034] As a preferred embodiment of the present invention: the lifting end of the Z-axis lifting cylinder is on the same horizontal plane as the four corners of the positioning fixture, and there is a synchronous switch to uniformly control the lifting of the Z-axis. There are four XZ-axis cylinders, which are arranged flatly at the four corners of the positioning strip superimposed filling diaphragm structure. The superimposed automatic filling Z-axis descends and X-axis moves laterally to perform positioning strip superimposed positioning.

[0035] As a preferred embodiment of the present invention: the XZ axis cylinder is driven by two independent lifting structures, and its Z-axis output end is filled and closed by the lowering of the screen-printed film, while the X-axis is slidably translated.

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] 1) The L-shaped connecting seat and multiple holes on the surface are used to adapt to the installation of the screen-printed short-side positioning piece superimposed filling fixture positioning equipment. Based on the rotation of the master and slave pulleys driven by the brushless motor, the high-speed rotation of the inward toothed track at both ends is achieved. This allows the glass that needs to be positioned to be precisely transferred along the inward toothed track, avoiding manual operation, improving the efficiency of transfer, and further improving the filling and positioning accuracy of the screen-printed short-side positioning piece.

[0038] 2) The conveyor belt guide rod structure enables automatic transfer of the glass to be transported. Combined with positioning fixtures, positioning strips, superimposed filling films, and filling film positioning strips, the tempered glass to be laminated is automatically transferred to the surface of the carrier plate. Then, it is pressed by the filling film positioning strips and rubber frame. During the pressing process, it is tightened, thereby achieving better splicing. Based on the corresponding expansion and contraction, it further achieves splicing. It solves the problem of positioning the substrate film and diffusion film, prevents uneven film edges during the screen printing process, and avoids white edges on the short sides of the screen printing. It effectively solves the problem of edge alignment. Moreover, the limitation of the short side structure of the screen printing effectively avoids the edge position.

[0039] 3) Effectively solves the positioning and bonding efficiency of the substrate film and diffusion film itself. It can achieve more convenient corner positioning by superimposing positioning strips on the filling film bonding area and the surrounding positioning fixtures, thus improving the efficiency of the positioning stage. In the positioning stage, there is no complete fixture to replace manual positioning of the screen printing edge. The positioning stage of the diffusion plate positioning strip superimposed filling film needs to be limited according to the specific size. At the same time, the positioning strips of the fixture are uniformly single-layered, while the screen printing film is mostly two to four layers. The purpose of positioning is to protect the screen. Therefore, the positioning by superimposing positioning strips on the filling fixture effectively achieves the consistency of the positioning strip height and the screen printing film height. It is simultaneously operated by four independent lines. In terms of function, it can be used as a Z-axis box for synchronous operation or as an X-axis operation, which is more flexible and has better consistency in synchronous axial lifting.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Please see Figures 1-7 This invention provides a technical solution: a screen-printed short-side positioning sheet superimposed filling fixture positioning device, comprising a support mechanism 1, a transmission mechanism 2, and a positioning mechanism 3;

[0050] The support mechanism 1 also includes four L-shaped connecting seats 11 and a support frame 12;

[0051] The L-shaped connecting seats 11 are arranged in pairs on the processing table, and the bearing frame 12 is arranged horizontally on the L-shaped connecting seats 11.

[0052] A rolling shaft 14 is also inserted between the limiting bearings 13 on one side, and a pulley 15 is provided at one end of the rolling shaft 14.

[0053] It also includes a brushless motor 21 located on the side of the pulley 15 of the transmission mechanism 2. The output end of the brushless motor 21 is fitted with a belt 22 through the drive pulley of the transmission mechanism 2. One end of the belt 22 is connected to the pulley 15 for transmission.

[0054] The bottom of the brushless motor 21 is limited to the side of the L-shaped connector 11;

[0055] The track gears 22 are respectively supported on both ends of the rolling shaft 14 and rotate synchronously.

[0056] In this embodiment: synchronous rotation is achieved based on the transmission linkage between the track gear 22 and its specific rolling shaft 14. When the rolling shaft 14 is rotating, the pulleys 15 at both ends of the shaft core are also rotating.

[0057] The brushless motor 21 serves as the drive source. The rotation of the brushless motor 21 is controlled according to the rotation scheme of the belt 22 driven by the motor output end, which further realizes the rotation of the belts 22 on both sides.

[0058] Specifically: The flow line flows into the position of fixture 1 for transportation: Step 1: Control the brushless motor 21 to be powered on;

[0059] At this time, the base of the brushless motor 21 rotates at high speed relative to the output end of the motor. When the output end of the motor is rotating, the drive wheel controls one end of the brushless motor 21 to control the rotation of the inward toothed track 24. The output end of the brushless motor 21 drives the drive pulley to rotate. When the pulley 15 is driven by the corresponding brushless motor 21, the drive structure at the output end of the drive structure rotates. When the drive structure rotates, the control roller 14 rotates at high speed, achieving synchronous displacement, thereby achieving the transmission of the screen printing structure to form synchronous displacement.

[0060] Each track gear 22 surface also includes an inwardly turned toothed track 24 that meshes with its teeth. The two inwardly turned toothed tracks 24 are spaced and fitted together in the middle of the concave guide frame 25. The two inner side walls of the concave guide frame 25 are also provided with a belt guide rod 26, which is flush with the inner and outer sides of the inwardly turned toothed track 24.

[0061] The upper ends of the two outermost pairs of belt guide rods 26 are connected to the concave guide frame 25 through several protrusions 27. Based on the position of the linear guide groove of the belt guide rod 26, an XY axis 28 for automatic stacking and filling of positioning strips is also installed.

[0062] Its purpose is to more conveniently and accurately control the traction rotation on the designated track structure when the adapted motor drives the track gear 22 to rotate, and to achieve the mutual matching rotation on the inward toothed track 24 according to the guidance of the corresponding belt guide rod 26.

[0063] In this embodiment: the XY axis 28 further includes: a Z-axis lifting cylinder 281 and a linear displacement structure 282 that is connected to the air outlet of the Z-axis lifting cylinder 281, a cable chain 283 for wire transmission, and multiple positioning brackets 284 that serve to position the positioning piece stacking fixture.

[0064] In this embodiment: multiple positioning brackets 284 are respectively disposed on the outer side wall of the belt guide rod 26;

[0065] The linear displacement structure 282 is slidably connected to the belt guide rod 26 via the positioning bracket 284, and each drag chain 283 is respectively set on the outside of the linear displacement structure 282.

[0066] The use of belt guide rod 26 is employed to guide the connection and binding wires of positioning bracket 284 and its corresponding drag chain 283, thereby protecting against wire entanglement.

[0067] At this time, when the two track gears 22 are controlled to rotate, the inner toothed tracks 24 adapted on both sides will rotate synchronously when the inner toothed tracks 24 on the surface are driven.

[0068] This allows the positioning strip superimposed filling film structure to be placed on the surface of the inward-turning toothed track 24 and roll around the surface of the belt guide rod 26. At this time, the glass that needs to be filmed moves linearly according to the surface of the inward-turning toothed track 24. Based on the padding state of the positioning bracket 284, the energization of the Z-axis lifting cylinder 281 controls the extension and retraction of the linear displacement structure 282, directly adjusting the direction of the positioning bracket 284 to achieve extension and retraction. After being pushed by the top cylinder, sliding extension and retraction are achieved. Then, the positioning bracket 284 drives the structure of the top horizontal plate 31 to change. Moreover, combined with the four synchronously running lifting Z-axis lifting positioning fixtures, the four ends of the fixtures flowing into the flow plate line can be moved up and down synchronously in the Z-axis direction.

[0069] In this embodiment: the positioning mechanism 3 is disposed on the horizontal plate 31 on the surface of the adjacent positioning bracket 284, and the middle area of ​​the two flush horizontal plates 31 is provided with a membrane fixture fitting structure 32:

[0070] In this embodiment, the membrane fixture bonding structure 32 further includes an adjustment pad 33 for adjusting the gaps between the glass during the adjustment process;

[0071] The displacement protrusion 34 for adjusting the position and the XZ axis 35 for positioning strip superimposed filling diaphragm 43 filling, with the outer side of the XZ axis 35 adapted to drive the fixed motor 36.

[0072] The inverted end of the fixed motor 36 is close to the outside of the XZ axis 35, and its bottom is supported by the bottom end of the fixed motor 36.

[0073] The XZ axis 35 is used to control the telescopic drive structure to reset the displacement, and combined with the fixed motor 36 and the corresponding control motor 36 of the fixed motor 36, it serves as the power control for the normal telescopic operation of the XZ axis 35.

[0074] In this embodiment: the lower end of the belt guide rod 26 is also provided with several I-shaped support blocks 261, and the four corners of the several I-shaped support blocks 261 are fastened to the external support structure by screws.

[0075] The inner sidewall of the horizontal plate 31 is provided with a positioning strip superimposed filling film bonding area 4. The positioning strip superimposed filling film bonding area 4 includes a filling film positioning strip 41 that is adapted to and clamped with the inner sidewalls of the two horizontal plates 31. A bonding groove 42 for bonding is opened in the middle of the filling film positioning strip 41.

[0076] A positioning strip is provided in the middle of the groove 42, and a filling film 43 is superimposed.

[0077] The filling film positioning strip 41 and the positioning strip to be bonded are aligned with the filling film 43, and then positioned according to the four corners of the bonding groove 42.

[0078] In this embodiment: a positioning fixture 44 for frame selection positioning is provided on the outer side of the positioning strip superimposed filling film 43. Several assembly rings 45 are provided on the bottom of the four sides of the bottom of the positioning fixture 44. A bearing plate 46 is provided at the bottom of the assembly ring 45. A bearing mechanism 5 is provided at the bottom of the bearing plate 46.

[0079] The bearing mechanism 5 includes an adjustment frame 51 located at the top center of the bearing plate 46, a guide groove 52 in the middle, a limiting hole at one end of a circular opening 53, and a bracket 55 at one end of the limiting hole.

[0080] The use of limiting holes and corresponding bracket 55 structure further realizes the extrusion of the upper and lower films that need to be combined and positioned. During the positioning stage, the positioning fixture 44 realizes the comparative positioning of the four sides of the glass film.

[0081] The specific plan for raising the height is as follows:

[0082] The XZ axis 35 and the designated fixed motor are energized to raise the positioning strip superimposed filling film that needs to be positioned. Then, the horizontal plate 31 is controlled to move upward, which realizes the position adjustment of the filling film positioning strip 41 and the transmission of the positioning strip superimposed filling film to the film-applying slot position. The film is positioned according to the slot of the film-applying slot 42, realizing the unified drive of the screen printing short side positioning piece superimposed filling fixture.

[0083] In this embodiment: a pneumatic cylinder 54 is provided at the bottom center of the support plate, a support base 56 is provided at the bottom of the pneumatic cylinder 54, a sliding end 57 is provided at the bottom center of the support base 56, a support seat 58 is provided at the top of the sliding end 57, a mounting support plate 59 is provided at one end of the support seat 58, a mounting base 591 is provided on the mounting support plate 59, a support cylinder 592 is provided at the top of the mounting base 591, and a transverse support plate 593 is provided at the bottom of the support cylinder 592.

[0084] The load-bearing cylinder 592, when energized, controls the horizontal support plate 593 to lift upwards. During the lifting process, it also controls the height of the support plate 59 to move the specified glass structure upwards.

[0085] The bottom edge of the transverse support plate 593 is telescopically connected to the four corners of the transverse support plate 593 via the telescopic end 594;

[0086] A transmission mechanism 6 is located at the rear end of the belt guide rod 26;

[0087] The transmission mechanism 6 includes a drive bracket 61 at one end of the guide rods 26 of multiple belt lines. The drive bracket 61 is supported by two half-piece bracket structures 62.

[0088] The two-part bracket structure 62 is used to position the belt 22 and its track gear 22 so that when the central rolling shaft 14 rotates, the two track gears 22 can be rotated in an adjustable manner.

[0089] The top center of the two-piece bracket structure 62 is supported by a limiting shaft seat 63. The center of the limiting shaft seat 63 is provided with a transmission roller 64. The center of the shaft of the transmission roller 64 is fitted with a driven sleeve wheel 65 through a transmission sprocket. The surface of the driven sleeve wheel 65 is fitted with one end of the track.

[0090] The limiting shaft seat 63 and its transmission sprocket are connected to the output gear of the brushless motor 21 to drive the specific connection structure to rotate.

[0091] During the positioning stage, the user needs to operate the support plate 46 to move it down, so that the positioning strip superimposed filling film 43 that needs to be positioned and filled can be directly transferred to the groove that fits the slot. This makes it more convenient to insert the positioning strip superimposed filling film 43 into the middle of the positioning fixture 44 and then control the lower end position of the pneumatic cylinder 54.

[0092] Specific positioning:

[0093] Then, the bearing plate 46 is controlled to be pressed upward to achieve the compression of the film. After the compression is completed, it is disassembled, thus completing the positioning of the screen-printed short side positioning piece superimposed filling fixture. At the same time, the screen printing edge technology needs to be in accordance with the following: the film strips attached to the fixture are uniformly single-layered, and the required screen-printed film usually needs to reach 2-4 layers. This ensures that the thickness meets the requirements when screen printing positioning and filling, which can play a protective role for the protective mesh plate.

[0094] Moreover, the specific positioning requires four sets of lifting fixtures that can achieve XZ axial movement. The direction of the silk-screened positioning film can be more specific for the short side positioning pieces to be superimposed and filled for positioning at the front and rear positions. The main thing is that these four sets of XZ components are used in conjunction with the lifting Z fixture to superimpose and fill the positioning pieces. In addition, the XZ axis cylinder can realize synchronous movement in the X axis and lifting in the Z axis.

[0095] After the streamlined plate that needs to be superimposed and positioned flows into the fixture and reaches the position of the positioning fixture for lifting Z-axis displacement;

[0096] Simultaneously, four independent Z-axis structures are lifted, and at this time, the 2-4 layers of protective mesh plates between multiple screen-printed films are filled, squeezed and closed to maintain the function of superimposed positioning for Z-axis descent and X-axis lateral movement.

[0097] After the screen printing positioning is completed, the X-axis control is started simultaneously to send the screen-printed flow line out of the designated fixture. The screen-printed positioning film has multiple layers. The positioning is done in advance during the filling stage to effectively prevent the problem of white edge defects caused by uneven film edges during the screen printing process, thus improving the product yield.

[0098] The specific filling process requires uniform adjustment of the synchronous downward movement of the four specified Z-axis structures to ensure that the fixture is fully compressed and merged into a single piece.
