[0022] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] The utility model provides a rubber strip feeding and adding mechanism, including a workbench and a loading tray 2, a tray bracket 3, an intermittent shifting mechanism 4, an assembly robot arm 5 and an assembly station 6 on the workbench, an assembly body 9 is clamped on the assembly station 6, a loading tray 2 is placed on the tray bracket 3, a plurality of rubber strips 8 are placed side by side in the loading tray 2, the intermittent shifting mechanism 4 is arranged on the tray bracket 3, the moving direction of the intermittent shifting mechanism 4 is perpendicular to the length direction of the rubber strips 8 in the loading tray 2, the intermittent shifting mechanism 4 intermittently shifts the loading tray 2, and the assembly robot arm 5 transfers and clamps the corresponding rubber strips 8 in the loading tray 2 to the assembly body 9.

[0027] The method of using the utility model is as follows: a worker manually fills the loading tray 2 with rubber strips 8, and the assembly 9 to be installed has also been transferred from the workstation of the previous process to the assembly station 6, and then the assembly robot 5 clamps the rubber strips 8 in the loading tray 2 and transfers and installs them on the assembly 9 on the assembly station 6; then the intermittent displacement device steps the loading tray 2 one unit distance each time, and makes the position of the next rubber strip 8 correspond to the position of the assembly robot 5. Similarly, the assembly robot 5 clamps the corresponding rubber strips 8 in the loading tray 2 and transfers and installs them on the assembly 9 on the assembly station 6.

[0028] Specifically, the loading tray 2 is composed of a square plate 21 and a plurality of placement grooves 22 arranged at intervals thereon, all the placement grooves 22 are arranged in a direction perpendicular to the length direction of the placement grooves 22, the depth value of each placement groove 22 is less than the thickness value of the rubber strip 8, and a rubber strip 8 can be placed in each placement groove 22. Since the depth value of the placement groove 22 is less than the thickness value of the rubber strip 8, a part of the rubber strip 8 is in the placement groove 22, and the other part extends out of the placement groove 22, so that the assembly robot arm 5 can clamp the extended part of the rubber strip 8.

[0029] In order to facilitate the assembly of the gripping fingers of the robot arm 5 so that there is space to place them on the two sides of the rubber strip 8 when gripping the rubber strip 8, each two adjacent placement grooves 22 are staggered in the length direction thereof, that is, the end of each alternate placement groove 22 protrudes compared to the ends of other placement grooves 22.

[0030] Specifically, the intermittent shift mechanism 4 includes a fixed base plate 41, a clamping mechanism 42 and a first linear electric slide rail 43. The fixed base plate 41 is placed on the tray bracket 3. The first linear electric slide rail 43 is fixed on the tray bracket 3. One end of the fixed base plate 41 is fixed to the moving module of the first linear electric slide rail 43. The clamping mechanism 42 is arranged on the upper surface of the fixed base plate 41. The clamping mechanism 42 can clamp the loading tray 2 placed on the fixed base plate 41. When the loading tray 2 needs to be displaced step by step, the moving module of the first linear electric slide rail 43 drives the fixed base plate 41 to move step by step by a distance unit, thereby driving the loading tray 2 on the fixed base plate 41 to move step by step. The clamping mechanism 42 clamps the loading tray 2 to ensure that the loading tray 2 and the fixed base plate 41 move synchronously to prevent the loading tray 2 from sliding off the fixed base plate 41.

[0031] Specifically, the assembly robot 5 includes a second linear electric slide 51, a stand 52 and a clamp 53. The bottom end of the stand 52 is fixed on the moving module of the second linear electric slide 51, and the clamp 53 is fixed on the top of the stand 52. The stand 52 can be raised and lowered. The moving module of the second linear electric slide 51 can drive the stand 52 and the clamp 53 to move between the loading tray 2 and the assembly station 6. When the clamp 53 moves, the stand 52 is in a long state, so that the clamp 53 is separated from the components on the workbench by a large distance to avoid mutual interference. When the clamp 53 needs to grab the rubber strip 8, the stand 52 shrinks to reduce the height of the clamp 53.

[0032] The assembly station 6 includes a first support platform 61, a second support platform 62, a third support platform 63 and two clamping assemblies 64. The first support platform 61, the second support platform 62 and the third support platform 63 are arranged at intervals. The two clamping assemblies 64 are respectively arranged at the first support platform 61 and the second support platform 62. The clamping assembly 64 includes two oppositely arranged rotating pressing cylinders 641. The assembly 9 is placed on the first support platform 61, the second support platform 62 and the third support platform 63, and its length direction is consistent with the arrangement direction of the first support platform 61, the second support platform 62 and the third support platform 63. The clamping assembly 64 clamps and fixes the assembly 9 to prevent the assembly 9 from shifting during installation and affecting the installation effect. After the assembly 9 is transferred to the first support platform 61, the second support bar and the third support platform 63, the two rotary pressing cylinders 641 of the clamping assembly 64 first rotate the pressing plate to the space above the part of the assembly 9 to be pressed, and then the rotary pressing cylinder 641 lowers the pressing plate to press down the part to be pressed.

[0033] A guide mechanism 7 is provided between the tray support 3 and the assembly station 6. The guide mechanism 7 includes a fixed support 71 and a rotating wheel 72. The bottom end of the fixed support 71 is fixed to the workbench, and the rotating wheel 72 is rotatably connected to the top end of the fixed support 71. The rubber strip 8 is very soft. The main function of the guide mechanism 7 is to prevent the back half of the rubber strip 8 from being vacated and collapsing when the front half of the rubber strip 8 is installed on the assembly 9 (if the back half of the rubber strip 8 collapses, it will not be tangent to the assembly 9, increasing the difficulty of installation). The rotating wheel 72 of the guide mechanism 7 supports and guides the back half of the rubber strip 8 to ensure that the rubber strip 8 is always tangent to the assembly 9.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
