Description

Technical Field

[0001] This utility model relates to the field of glass cover assembly technology, and in particular to an adaptive positioning fixture for automated production lines. Background Technology

[0002] Currently, various electronic products have displays. During the assembly of the displays, glass covers need to be assembled onto the main body of the product. In traditional glass cover assembly machines, the main body of the product is fixed by a clamping and positioning device on the assembly machine, and a robotic arm picks up the glass cover and assembles it onto the main body. However, for automated production lines, the main body of the product and the glass cover are transported to each station along with the fixture. The clamping device needs to be set on the fixture. However, in addition to the assembly process, the glass cover also needs to undergo processes such as film removal and alignment. Therefore, the clamping device is required to be able to flexibly switch between clamping and open states at each station. In order to achieve the above objectives, it is necessary to develop an adaptive positioning fixture for automated production lines. Utility Model Content

[0003] The purpose of this invention is to provide an adaptive positioning fixture for automated production lines to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An adaptive positioning fixture for an automated production line includes a fixture base plate, a mounting plate, a first clamp assembly, and a second clamp assembly. The fixture base plate has a placement cavity in the center. Limiting bosses are provided at each of the four corners of the placement cavity on the fixture base plate. Each limiting boss has a supporting plane, a lower limiting arc surface, and an upper limiting arc surface. The upper end of the lower limiting arc surface is connected to the inner side of the supporting plane, and the lower end of the upper limiting arc surface is connected to the outer side of the supporting plane. Mounting bosses are provided around the perimeter of the placement cavity on the fixture base plate. The mounting plate is fixed to the lower end of the fixture base plate and has a mounting cavity between it and the mounting bosses. A first clearance hole is provided on the fixture base plate corresponding to the inner side of the mounting cavity. The first clamp assembly includes a first slide, a first slider, a first elastic telescopic member, and a first clamping block. The first slide is fixed above the mounting plate. The upper end of the first slider is fixed to the first clamping block, and the lower end is slidably connected to the first slide. Both ends of the first elastic telescopic member are respectively fixed... On the outside of the fixture base plate and the first clamping block, the outer end of the first clamping block corresponds to the mounting cavity, and the inner end of the first clamping block corresponds to the first clearance hole and the lower side of the placement cavity. Multiple sets of the first clamping assembly are provided and correspond to a pair of right-angled sides of the placement cavity respectively. The second clamping assembly includes a second slide, a second slider, a second elastic telescopic member, and a second clamping block. The second slide is fixed above the mounting plate. The upper end of the second slider is fixed on the second clamping block and the lower end is slidably connected to the second slide. The two ends of the second elastic telescopic member are fixed on the outside of the fixture base plate and the second clamping block respectively. The outer end of the second clamping block corresponds to the mounting cavity, and the inner end of the second clamping block corresponds to the second clearance hole and the upper side of the placement cavity. A first limiting block corresponding to the mounting cavity is provided on the mounting boss. A second limiting block is provided on the outside of the second clamping block. The inner end face of the second limiting block contacts the outer end face of the first limiting block. A V-groove is provided on the inner side of the second clamping block.

[0006] Further description of the present invention: The mounting boss includes a top mounting plate and an adjusting block. The lower end of the top mounting plate is connected to the base plate of the fixture. A sliding groove is provided on the top mounting plate. The adjusting block is fixed in the sliding groove by screws and is slidably connected to the sliding groove. A first limiting block is provided below the adjusting block.

[0007] Further description of the present invention: The base plate of the fixture is provided with multiple sets of second clearance holes, and one set of second clearance holes is provided on each side of the limiting boss.

[0008] Further description of this utility model: The base plate of the fixture is also provided with suction cup clearance holes, and four sets of suction cup clearance holes are provided, corresponding to the four corners of the placement cavity.

[0009] Further description of this utility model: The base plate of the fixture is also provided with anti-misalignment through holes. Two sets of anti-misalignment through holes are provided in the placement cavity, and the diameters of the two sets of anti-misalignment through holes are not equal.

[0010] Further description of the present invention: The mounting plate is provided with a first guide hole and a second guide hole, the first guide hole corresponding to both sides of the first slide, and the second guide hole corresponding to both sides of the second slide.

[0011] The beneficial effects of this utility model are as follows: The positioning fixture of this design is sequentially transported to each processing station by a conveyor belt. At each processing station, a lever that can pass through the first clearance hole is provided. By driving the lever to move outward, the first slider and the second slider are driven to move outward along the first slide table and the second slide table, so that the first clamping block and the second clamping block respectively compress the first elastic telescopic member and the second elastic telescopic member, thereby putting the first clamping assembly and the second clamping assembly into the open state. In the open state of the positioning fixture, the product body is placed on the lower side of the placement cavity, and the lower end of the product body is in contact with the bottom of the placement cavity. The four corners of the product body are limited by the lower limit arc surface. Initial positioning is performed, with the glass cover plate placed on top of the placement cavity. The lower corners of the glass cover plate rest on the supporting plane, and the four corners are initially positioned under the constraint of the upper limit arc surface. When the lever resets, the first clamping block on the two right-angled sides of the placement cavity pushes the product body and cooperates with the inner wall of the placement cavity, thereby fixing the product body horizontally. The second clamping blocks around the placement cavity also move towards the glass cover plate until the inner end face of the second limiting block contacts the outer end face of the first limiting block, at which point the four edges of the glass cover plate are all within the V-groove, thus enabling precise positioning and fixation of the glass cover plate. The advantage of this design is that it allows for flexible opening or clamping of the first and second clamping components at various processing stations, facilitating operations such as film removal and alignment of the glass cover plate, adapting to the needs of automated production, and improving production efficiency and accuracy.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] like Figures 1 to 4As shown, an adaptive positioning fixture for an automated production line includes a fixture base plate 1, a mounting plate 2, a first clamp assembly 3, and a second clamp assembly 4. The fixture base plate 1 has a placement cavity 11 in the middle. Limiting bosses 12 are provided at each of the four corners of the placement cavity 11 on the fixture base plate 1. Each limiting boss 12 has a supporting plane 121, a lower limiting arc surface 122, and an upper limiting arc surface 123. The upper end of the lower limiting arc surface 122 is connected to the inner side of the supporting plane 121, and the lower end of the upper limiting arc surface 123 is connected to the outer side of the supporting plane 121. The fixture base plate 1... Mounting bosses 13 are provided around the perimeter of the placement cavity 11. The mounting plate 2 is fixed to the lower end of the fixture base plate 1 and has a mounting cavity between it and the mounting bosses 13. The fixture base plate 1 has a first clearance hole 14 corresponding to the inner side of the mounting cavity. The first clamp assembly 3 includes a first slide 31, a first slider 32, a first elastic telescopic member 33, and a first clamping block 34. The first slide 31 is fixed above the mounting plate 2. The upper end of the first slider 32 is fixed to the first clamping block 34, and the lower end is slidably connected to the first slide 31. The two ends of the first elastic telescopic member 33 are respectively fixed... The first clamp assembly 3 is fixed to the outside of the fixture base plate 1 and the first clamping block 34. The outer end of the first clamping block 34 corresponds to the mounting cavity, and the inner end of the first clamping block 34 corresponds to the first clearance hole 14 and the lower side of the placement cavity 11. The first clamping assembly 3 is provided in multiple sets and corresponds to a pair of right-angled sides of the placement cavity 11 respectively. The second clamping assembly 4 includes a second slide 41, a second slider 42, a second elastic telescopic member 43, and a second clamping block 44. The second slide 41 is fixed above the mounting sealing plate 2. The upper end of the second slider 42 is fixed to the second clamping block 44, and the lower end is attached to the second slide 41. 1. A sliding connection is provided. The two ends of the second elastic telescopic member 43 are respectively fixed to the base plate 1 of the fixture and the outside of the second clamping block 44. The outer end of the second clamping block 44 corresponds to the installation cavity. The inner end of the second clamping block 44 corresponds to the second clearance hole 15 and the upper side of the placement cavity 11. The mounting boss 13 is provided with a first limiting block 1321 corresponding to the installation cavity. The outer side of the second clamping block 44 is provided with a second limiting block 441. The inner end face of the second limiting block 441 contacts the outer end face of the first limiting block 1321. The inner side of the second clamping block 44 is provided with a V-groove 442.

[0020] The positioning fixture of this design is sequentially transported to each processing station via a conveyor belt. At each processing station, a lever is provided that can pass through the first clearance hole 14. By driving the lever to move outward, the first slider 32 and the second slider 42 are driven to move outward along the first slide table 31 and the second slide table 41, causing the first clamping block 34 and the second clamping block 44 to compress the first elastic telescopic member 33 and the second elastic telescopic member 43 respectively. This, in turn, puts the first clamping assembly 3 and the second clamping assembly 4 into the open state. In the open state of the positioning fixture, the main body of the product is placed on the lower side of the placement cavity 11, with the lower end of the main body of the product in contact with the bottom of the placement cavity 11. The four corners of the main body of the product are initially positioned under the constraint of the lower limit arc surface 122. The glass cover is placed on the upper side of the placement cavity 11, with its four lower corners resting on the supporting plane 121. The four corners of the glass cover are initially positioned by the upper limit arc surface 123. When the lever resets, the first clamping block 34, located on the two right-angled sides of the placement cavity 11, pushes the product body and engages with the inner wall of the placement cavity 11, thereby fixing the product body horizontally. Meanwhile, the second clamping blocks 44 around the placement cavity 11 also move towards the glass cover until the inner end face of the second limiting block 441 contacts the outer end face of the first limiting block 1321, at which point the edges of the glass cover are all within the V-groove 442, enabling precise positioning and fixation of the glass cover. The advantage of this design is that it allows for flexible opening or clamping of the first clamping assembly 3 and the second clamping assembly 4 at various processing stations, facilitating operations such as film removal and alignment of the glass cover, adapting to automated production needs, and improving production efficiency and precision.

[0021] The mounting boss 13 includes a top mounting plate 131 and an adjusting block 132. The lower end of the top mounting plate 131 is connected to the base plate 1 of the fixture. A sliding groove 1311 is provided on the top mounting plate 131. The adjusting block 132 is fixed in the sliding groove 1311 by screws and is slidably connected with the sliding groove 1311. A first limiting block 1321 is provided below the adjusting block 132.

[0022] By manually driving the adjusting block 132 to move within the sliding groove 1311 and fixing the adjusting block 132 with screws, the distance between the first limiting block 1321 and the edge of the glass cover can be adjusted, thereby limiting the maximum distance that the second clamping block 44 moves into the placement cavity 11. Thus, the clamping pressure on the glass cover can be flexibly adjusted according to the clamping pressure requirements, avoiding excessive pressure that could damage the glass cover. Of course, it can also be adjusted according to production needs, so that the pressure of the second clamping block 44 on the glass cover is inward, and the lower end of the V-groove 442 supports the edge of the glass cover.

[0023] The fixture base plate 1 is provided with multiple sets of second clearance holes 15, with one set of second clearance holes 15 on each side of the limiting boss 12.

[0024] The second clearance hole 15 is provided so that the positioning camera and the supplementary light source can cooperate through the second clearance hole at the alignment station to shoot and position the four corners of the product body and the glass cover.

[0025] The fixture base plate 1 is also provided with suction cup clearance holes 16, and four sets of suction cup clearance holes 16 are provided, corresponding to the four corners inside the placement cavity 11.

[0026] Suction cups can be installed at each processing station. The suction cups pass through the suction cup clearance holes 16 and adhere to the lower end face of the product body, thereby achieving vertical fixation. Four sets of suction cup clearance holes 16 are provided, not only to ensure that the suction cups are evenly distributed, but also so that the protruding camera of products such as mobile phones and tablets can be aligned with the suction cup clearance holes 16, allowing the product body to be placed flat. Moreover, the four sets of suction cup clearance holes 16 can adapt to different placement directions of the product body.

[0027] The fixture base plate 1 is also provided with anti-mistake through holes 17. Two sets of anti-mistake through holes 17 are provided in the placement cavity 11, and the diameters of the two sets of anti-mistake through holes 17 are not equal.

[0028] Positioning rods can be installed at each processing station. Two positioning rods of different diameters are inserted upward into two sets of anti-misalignment through holes 17 of unequal diameters to avoid the positioning fixture being placed in the wrong direction.

[0029] The mounting plate 2 is provided with a first guide hole 21 and a second guide hole 22. The first guide hole 21 corresponds to both sides of the first slide 31, and the second guide hole 22 corresponds to both sides of the second slide 41.

[0030] The levers installed at each workstation pass upward through the second guide hole 22 and move along the second guide hole 22 to drive the second clamping block 44 to open or clamp. Under the guidance of the second guide hole 22, the second clamping block 44 can run more smoothly and with higher precision.

[0031] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
