Description

Technical Field

[0001] The utility model relates to the technical field of plastic barrel processing, in particular to a feeding and positioning mechanism for a plastic barrel cover. Background Art

[0002] The materials of plastic barrels are mostly made of polyethylene, polypropylene, polyester and other plastics through blow molding, injection molding, suction molding and rotation molding.

[0003] After the rubber barrel is formed, the matching barrel cover needs to be installed on the rubber barrel. When the rubber barrel is fed, it is usually transported by a conveyor and then loaded by a robot. However, the position of the barrel cover is prone to offset during the conveying process. When the robot grabs the barrel cover, it needs to repeatedly adjust the position of the gripper to accurately dock with the barrel body, which affects the assembly efficiency of the barrel and the barrel cover.

[0004] Therefore, a plastic barrel cover feeding and positioning mechanism is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a feeding and positioning mechanism for a plastic barrel cover, which has the advantages of accurate positioning and easy docking with the barrel body, and solves the problem that the position of the barrel cover is easily offset during the conveying process. When the robot grabs the barrel cover, it is necessary to repeatedly adjust the position of the clamping claws to accurately dock with the barrel body, thereby affecting the assembly efficiency of the barrel and the barrel cover.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding and positioning mechanism for a plastic barrel cover, comprising a feeding mechanism and a positioning mechanism arranged in parallel;

[0007] The feeding mechanism comprises a vibration table, and a linear guide rail is provided on the vibration table;

[0008] The positioning mechanism includes a pair of support seats, and a positioning platform is commonly fixed on the top surfaces of the pair of support seats. The bottom surface of the positioning platform is rotatably connected to a pair of rotatable arms via a rotating shaft. The two rotating arms are staggered and distributed crosswise, and both ends of the rotating arms are fixed with positioning rods extending to the top surface of the positioning platform.

[0009] Furthermore, inner walls on both sides of the linear guide rail form platforms.

[0010] Furthermore, a pair of positioning cylinders are hinged on the side of the positioning platform through an L-shaped mounting plate, a push block is fixed to the output end of the positioning cylinder, and the end of the push block is rotatably arranged on the rotating arm through a rotating shaft.

[0011] Furthermore, the positioning platform is provided with two pairs of arc-shaped avoidance grooves for allowing the two pairs of positioning rods to move flexibly.

[0012] Furthermore, the right opening of the positioning platform is connected to the outlet of the linear guide rail, and the inner walls on both sides of the positioning platform form a support platform.

[0013] Furthermore, a position sensor is fixed on the positioning platform, and a blocking cylinder is also fixed on the positioning platform.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The plastic barrel cover feeding and positioning mechanism can use two pairs of positioning rods to fine-tune the position of the plastic cover so that it is centered on the center of the positioning table support surface. The robot does not need to repeatedly adjust the position of the clamping claws. The barrel cover can be directly clamped and accurately docked with the barrel body, thereby improving processing efficiency.

[0016] The position of the barrel cover to be positioned can also be sensed by the position sensor, so that the blocking cylinder can be pushed out to block the subsequent barrel covers, thereby controlling the loading frequency of the barrel covers. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0024] See also Figure 1-5A feeding and positioning mechanism for a plastic barrel cover in this embodiment includes a feeding mechanism 1 and a positioning mechanism 2 arranged in parallel; the barrel cover is fed to the positioning mechanism 2 through the feeding mechanism 1, and is centered and positioned by the positioning mechanism 2, so that the feeding position of the barrel cover is accurate, which helps to accurately dock and assemble it with the barrel body.

[0025] The feeding mechanism 1 can realize the vibration feeding of the barrel cover, so that a plurality of barrel covers are arranged in sequence and sent to the positioning mechanism 2 for positioning. Figure 1-2 As shown, the feeding mechanism 1 includes a vibration table 101 , on which a linear guide rail 102 is disposed. The barrel cover is placed on the linear guide rail 102 , and the vibration table 101 generates vibration to achieve feeding.

[0026] The inner walls on both sides of the linear guide rail 102 form a platform 103, and the barrel cover can be placed on the inner platform 103 for feeding.

[0027] After the feeding mechanism 1 delivers the barrel cover to the positioning mechanism 2, the barrel cover can be centered and positioned by the positioning mechanism 2 to adjust the feeding position of the barrel cover. Figure 1 , Figure 3-5 As shown, the positioning mechanism 2 includes a pair of support seats 201, and a positioning platform 202 is commonly fixed on the top surface of the pair of support seats 201. A pair of positioning cylinders 203 are hinged on the side of the positioning platform 202 through an L-shaped mounting plate. A pushing block 204 is fixed to the output end of the positioning cylinder 203. The end of the pushing block 204 is rotatably connected to a rotating arm 205 through a rotating shaft. The two rotating arms 205 are staggered and distributed, and the centers of the two rotating arms 205 are rotatably arranged on the bottom surface of the positioning platform 202 through a rotating shaft. Positioning rods 206 extending to the top surface of the positioning platform 202 are fixed at both ends of the rotating arms 205.

[0028] Two pairs of arc-shaped avoidance grooves 207 are provided on the positioning platform 202 for the two pairs of positioning rods 206 to move flexibly. When the barrel cover moves onto the positioning platform 202, the positioning cylinder 203 is pushed out, and under the pushing action of the pushing block 204, the rotating arm 205 drives the positioning rod 206 to rotate in the corresponding arc-shaped avoidance groove 207, so that the position of the rubber cover can be fine-tuned by using the two pairs of positioning rods 206 to make it centered at the center of the supporting surface of the positioning platform 202.

[0029] A manipulator can also be arranged beside the positioning mechanism 2. After the position of the barrel cover is adjusted, the barrel cover can be directly grabbed by the manipulator and accurately docked with the barrel body, thereby improving the assembly efficiency of the rubber barrel.

[0030] The right opening of the positioning platform 202 is connected to the outlet of the linear guide rail 102 , and the inner walls on both sides of the positioning platform 202 form a support platform 208 . The inner support platform 208 of the positioning platform 202 is connected to the inner platform 103 of the linear guide rail 102 .

[0031] In addition, in order to control the feeding frequency of the barrel covers, a position sensor 209 is fixed on the positioning platform 202, and the barrel covers can be sensed by the position sensor 209. A blocking cylinder 210 is also fixed on the positioning platform 202. When the position sensor 209 senses the position of the barrel cover to be positioned, the blocking cylinder 210 is pushed out to block the subsequent barrel covers, thereby controlling the feeding frequency of the barrel covers.

[0032] By adopting the above-mentioned plastic barrel cover feeding and positioning mechanism, the barrel cover can be automatically centered and positioned, and the docking with the barrel body is more accurate. The specific feeding and positioning method is as follows:

[0033] The barrel cover is placed on the linear guide rail 102, and the vibration is generated by the vibration table 101 to achieve loading. When the barrel cover is sent to the positioning table 202 and the position sensor 209 senses the position of the barrel cover to be positioned, the blocking cylinder 210 is pushed out to block the subsequent barrel covers. At the same time, the positioning cylinder 203 is pushed out, and under the pushing action of the pushing block 204, the rotating arm 205 drives the positioning rod 206 to rotate in the corresponding arc-shaped avoidance groove 207, so that the position of the rubber cover can be fine-tuned by using two pairs of positioning rods 206 to make it centered at the center of the support surface of the positioning table 202, which is convenient for the robot arm on the side to clamp it.

[0034] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
