Description

Technical Field

[0001] The utility model relates to the technical field of buffer mechanisms, in particular to a gas spring buffer mechanism. Background Art

[0002] Gas spring is a kind of accessory that can perform functions such as support, buffer, brake, height adjustment, etc. Gas spring has a wide range of uses, and is generally common in the fields of flip cover, door and window opening support, etc., and is very convenient to use. The working principle of gas spring is to fill inert gas or oil-gas mixture in a closed pressure cylinder, so that the pressure in the cavity is many times higher than the atmospheric pressure, and the cross-sectional area of ​​the piston rod is smaller than the cross-sectional area of ​​the piston, thereby generating a pressure difference to realize the movement of the piston rod.

[0003] The existing buffer mechanism that prevents the mobile platform from directly colliding with the hard plate is merely a retractable spring set on both sides of the hard plate. The elastic force of the spring itself will cause the mobile platform to be pushed away from the hard plate when colliding, thereby failing to achieve accurate positioning of the carrier on the mobile platform, resulting in inaccurate subsequent processing of the products on the carrier.

[0004] Therefore, it is necessary to provide a gas spring buffer mechanism to solve the above problems. Utility Model Content

[0005] In order to overcome the above shortcomings, the purpose of the utility model is to provide a gas spring buffer mechanism to prevent the mobile platform from colliding with the hard plate when moving to feed materials, causing damage to the hard plate, thereby increasing the service life of the equipment and avoiding affecting subsequent product processing.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a gas spring buffer mechanism, including a buffer bracket; a buffer component and a plurality of hard plates are arranged on the buffer bracket, and the buffer component includes at least one buffer gas spring, and the buffer gas spring corresponds to the position of the hard plate.

[0007] When the mobile platform drives the carrier placed on it to approach the buffer component, the mobile platform first hits the buffer gas spring and then rests on the hard plate. The buffer gas spring is compressed by pressure and can also offset the impact force brought by the mobile platform, so that when the mobile platform rests on the hard plate again, it will not cause damage to the hard plate and itself.

[0008] Furthermore, the buffer gas spring and the abutting hard plate are symmetrically arranged along the center line of the length direction of the buffer bracket, and the buffer bracket is also provided with a sensor 1. In some embodiments, the buffer gas spring and the abutting hard plate are both provided with two, and the two buffer gas springs are arranged in the middle of the abutting hard plate. By providing two buffer gas springs, the impact force generated by the initial collision of the mobile platform can be shared, thereby having a better buffering effect; by providing two abutting hard plates, both sides of the mobile platform can have a place to abut, thereby making its movement and collision more stable.

[0009] Furthermore, the buffer assembly is connected to the mounting bracket via a lifting and distance-adjusting assembly, and the lifting and distance-adjusting assembly includes a lifting drive member that can drive the buffer bracket to move up and down. The lifting and distance-adjusting assembly can adjust the position of the buffer bracket in the vertical direction so that the entire buffer assembly can be adapted to the conveying assembly. When the mobile platform collides with the buffer mechanism, the lifting drive member can drive the buffer bracket to move upward according to the height of the mobile platform, so that the buffer gas spring on the buffer bracket can accurately abut against the mobile platform; when the product processing on the mobile platform is completed and needs to be moved to the next workstation, the lifting drive member can drive the buffer bracket to move downward to below the conveying assembly, thereby avoiding interference with the movement of the mobile platform.

[0010] Furthermore, the lifting and distance adjustment assembly also includes a vertically arranged lifting rail and a second guide rail. The lifting rail is located on a mounting seat vertically arranged on a mounting bracket. The abutting hard plate is slidably connected to the lifting rail through a hard plate mounting plate. The second guide rail is vertically arranged on the back of the mounting seat. The guide slider located on the back of the buffer bracket is inserted into the second guide rail and can move up and down along the second guide rail. The lifting rail and the second guide rail cooperate with each other to provide guidance for the lifting drive member to drive the buffer bracket to move up and down, and ensure the stability of the buffer bracket moving up and down. A through groove matching the size of the guide slider is provided in the middle of the second guide rail along its height direction.

[0011] Furthermore, it also includes a mounting bracket and a horizontal distance adjustment component, wherein a mounting seat is vertically arranged on the mounting bracket, and the buffer bracket is located on the mounting seat. The horizontal distance adjustment component includes an adjustment screw rod that passes through the mounting seat and is threadedly connected thereto, a fixed seat, and a horizontally arranged guide rail 1. An adjustment handwheel is arranged at the end of the adjustment screw rod away from the mounting bracket, and both sides of the mounting bracket are slidably connected to the guide rail 1. Rotating the adjustment screw rod can adjust the position of the buffer bracket in the horizontal direction, thereby adjusting the relative position between the buffer assembly and the transmission assembly in the horizontal direction, so that the buffer assembly can provide the best buffering effect to the mobile platform. The guide rail 1 can convert the rotation of the adjustment screw rod into the horizontal movement of the buffer bracket.

[0012] Furthermore, it also includes a mounting bracket supporting the buffer bracket, the mounting bracket is provided with a sensor distance adjustment assembly, the sensor distance adjustment assembly includes a distance adjustment bracket and a sensor 2 located thereon, the distance adjustment bracket is movably connected to the mounting bracket through a support block, the distance adjustment bracket is provided with a plurality of waist-shaped holes along its length direction, and the upper surface of the support block is provided with a plurality of locking holes corresponding to the positions of the waist-shaped holes.

[0013] When the distance adjustment is required, it is only necessary to match the waist-shaped holes on the distance adjustment bracket to the locking holes at different positions and lock them with screws. The operation is simple and convenient, and it can be applied to positioning of different types of carriers.

[0014] The second sensor is a distance sensor. By setting the second sensor, it can sense the distance position where the mobile platform drives the carrier to move above the second sensor, so as to further determine whether the mobile platform is completely against the hard board and whether the position of the carrier is accurate, thereby ensuring that the subsequent processing of the product on the carrier will not cause errors and ensuring the processing efficiency of the product.

[0015] It should be noted that the mounting brackets mentioned in this application are all the same mounting brackets.

[0016] Furthermore, the adjustable distance of the sensor 2 is 20 to 100 mm.

[0017] Beneficial effects of the utility model:

[0018] In the utility model, the buffer gas spring and the abutting hard plate cooperate with each other. When the mobile platform drives the carrier placed thereon to approach the buffer component, the mobile platform first hits the buffer gas spring and then abuts against the abutting hard plate. The buffer gas spring is compressed by pressure and can also offset the impact force brought by the mobile platform, so that when the mobile platform abuts against the abutting hard plate again, it will not cause damage to the abutting hard plate and itself, thereby effectively improving the service life of the equipment and avoiding affecting subsequent product processing.

[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0025] See attached Figures 1 to 3 As shown, a gas spring buffer mechanism in this embodiment includes a buffer bracket 1; a buffer component 2 and a plurality of abutting hard plates 23 are arranged on the buffer bracket 1, and the buffer component 2 includes at least one buffer gas spring 21, and the buffer gas spring 21 corresponds to the position of the abutting hard plate 23.

[0026] When the mobile platform 9 drives the carrier 10 placed thereon to approach the buffer assembly 2, the mobile platform 9 first hits the buffer gas spring 21 and then rests on the abutting hard plate 23. The buffer gas spring 21 is compressed by pressure and can also offset the impact force brought by the mobile platform 9, so that when the mobile platform 9 rests against the abutting hard plate 23 again, it will not cause damage to the abutting hard plate 23 and itself.

[0027] After the buffer gas spring 21 is compressed, it will not immediately provide a reverse thrust to the mobile platform 9 like the spring used in the prior art. Only when the buffer gas spring 21 is no longer subjected to external force, the buffer gas spring 21 will reset, which can prevent the mobile platform 9 from being reversely pushed away from the hard plate 23, causing the position of the carrier 10 on the mobile platform 9 to deviate relative to the transmission component 11, affecting the subsequent processing of the product on the carrier 10. It should be noted that the structure of the present application can be used in the transportation of parts such as batteries and tabs, but is not limited to the above two products.

[0028] The buffer gas spring 21 and the abutting hard plate 23 are symmetrically arranged along the center line of the length direction of the buffer bracket 1, and a sensor 22 is also arranged on the buffer bracket 1. In some embodiments, the buffer gas spring 21 and the abutting hard plate 23 are both provided with two, and the two buffer gas springs 21 are arranged in the middle of the abutting hard plate 23. By providing two buffer gas springs 21, the impact force generated by the initial impact of the mobile platform 9 can be shared, so as to have a better buffering effect; by providing two abutting hard plates 23, both sides of the mobile platform 9 can have a place to abut, so that its movement and impact are more stable.

[0029] The sensor 22 is a distance sensor. When the sensor 22 senses that the mobile platform 9 has moved to a specified distance, it will send a signal. The buffer gas spring 21 receives the signal and starts to deflate to avoid damage to the buffer gas spring 21 due to excessive impact force when the mobile platform 9 collides, thereby extending the service life of the buffer gas spring 21.

[0030] The buffer assembly 2 is connected to the mounting bracket 4 through a lifting and distance-adjusting assembly 6, and the lifting and distance-adjusting assembly 6 includes a lifting drive 61 that can drive the buffer bracket 1 to move up and down. The lifting and distance-adjusting assembly 6 can adjust the position of the buffer bracket 1 in the vertical direction so that the entire buffer assembly 2 can be adapted to the conveying assembly 11. When the mobile platform 9 collides with the buffer mechanism, the lifting drive 61 can drive the buffer bracket 1 to move upward according to the height of the mobile platform 9, so that the buffer gas spring 21 on the buffer bracket 1 can accurately abut against the mobile platform 9; when the product processing on the mobile platform 9 is completed and needs to be moved to the next workstation, the lifting drive 61 can drive the buffer bracket 1 to move downward to below the conveying assembly 11, thereby avoiding interference with the movement of the mobile platform 9.

[0031] It should be noted that the lifting drive member 61 here can be a driving cylinder or a lifting module, etc., as long as it is a mechanism that can achieve the lifting function in the prior art.

[0032] The lifting and distance adjustment assembly 6 also includes a vertically arranged lifting rail 64 and a second guide rail 63. The lifting rail 64 is located on a mounting seat vertically arranged on the mounting bracket 4. The abutting hard plate 23 is slidably connected to the lifting rail 64 through a hard plate mounting plate 62. The second guide rail 63 is vertically arranged on the back of the mounting seat. The guide slider 65 located on the back of the buffer bracket 1 is inserted into the second guide rail 63 and can move up and down along the second guide rail 63. The lifting rail 64 and the second guide rail 63 cooperate with each other to provide guidance for the lifting drive 61 to drive the buffer bracket 1 to move up and down, and ensure the stability of the buffer bracket 1 moving up and down. A through groove matching the size of the guide slider 65 is opened in the middle of the second guide rail 63 along its height direction.

[0033] It also includes a mounting bracket 4 and a horizontal distance adjustment component 3. The mounting bracket 4 is vertically provided with a mounting seat, and the buffer bracket 1 is located on the mounting seat. The horizontal distance adjustment component 3 includes an adjustment screw 33 that penetrates the mounting seat and is threadedly connected thereto, a fixed seat 31, and a horizontally arranged guide rail 15. An adjustment hand wheel 32 is arranged at the end of the adjustment screw 33 away from the mounting bracket 4, and both sides of the mounting bracket 4 are slidably connected to the guide rail 15. Rotating the adjustment screw 33 can adjust the position of the buffer bracket 1 in the horizontal direction, thereby adjusting the relative position between the buffer component 2 and the transmission component 11 in the horizontal direction, so that the buffer component 2 can provide the best buffering effect to the mobile platform 9. The guide rail 15 can convert the rotation of the adjustment screw 33 into the horizontal movement of the buffer bracket 1.

[0034] It also includes a mounting bracket 4 supporting the buffer bracket 1, and a sensor distance adjustment component 8 is arranged on the mounting bracket 4. The sensor distance adjustment component 8 includes a distance adjustment bracket 81 and a sensor 2 7 located thereon. The distance adjustment bracket 81 is movably connected to the mounting bracket 4 through a support block 82. The distance adjustment bracket 81 is provided with a plurality of waist-shaped holes 83 along its length direction, and a plurality of locking holes 84 corresponding to the positions of the waist-shaped holes 83 are arranged on the upper surface of the support block 82.

[0035] When the distance adjustment is required, it is only necessary to match the waist-shaped holes 83 on the distance adjustment bracket 81 to the locking holes 84 at different positions and tighten them with screws. The operation is simple and convenient, and it can be applied to positioning different types of carriers 10 .

[0036] The sensor 2 7 is a distance sensor. By setting the sensor 2 7, it can sense the distance position that the mobile platform 9 drives the carrier 10 to move above the sensor 2 7, so as to further determine whether the mobile platform 9 is completely against the hard board 23 and whether the position of the carrier 10 is accurate, thereby ensuring that the subsequent processing of the product on the carrier 10 will not cause errors and ensuring the processing efficiency of the product.

[0037] It should be noted that the mounting brackets 4 mentioned in this application are all the same mounting brackets 4 .

[0038] The adjustable distance of the sensor 2 7 is 20 to 100 mm.

[0039] See attached Figure 4 A conveying mechanism includes a gas spring buffer mechanism, and also includes multiple sets of transmission components 11 and a mobile platform 9. The transmission components 11 drive the mobile platform 9 to move, and multiple carriers 10 can be placed on the mobile platform 9.

[0040] The plurality of conveying components 11 are adjacently arranged to convey the mobile platform 9 to different processes.
