[0002] See attached Figure 1 , shown is a vulcanized rubber part. During the manufacturing process of the vulcanized rubber part, a plurality of vulcanized blanks are first grabbed by a piece placing machine and placed on a mold of a vulcanizer, and then vulcanized by the vulcanizer to obtain the vulcanized rubber part. The vulcanized rubber part includes an annular body with a sealing ring provided at one end of the annular body.

[0003] Currently, after the vulcanized rubber parts are vulcanized, they need to be collected one by one manually. Since each vulcanization process produces more than 100 vulcanized rubber parts, this collection method has a very low work efficiency. In addition, when workers are in close contact with the vulcanizer, the temperature of the vulcanizer is very high, which increases the labor intensity of the workers.

[0004] Therefore, there is an urgent need for a retrieval mechanism to improve the efficiency of retrieval of vulcanized rubber parts and reduce the labor intensity of workers. Utility Model Content

[0005] In response to the above technical problems, the present invention provides a piece-collecting mechanism for solving the problem that the vulcanized rubber parts currently need to be collected one by one manually after they are vulcanized. Since each vulcanization produces more than one hundred vulcanized rubber parts, the work efficiency of this collection method is very low, and when workers are in close contact with the high-temperature vulcanizing machine, the labor intensity of the workers is increased.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A pickup mechanism includes a main body and a gantry. A lifting drive unit is provided on the top of the gantry. A first slide is connected to the lifting drive unit. A second slide is provided on the first slide so as to slide perpendicularly to the movement direction of the lifting drive unit. A pickup unit is provided in a rotating manner in the second slide.

[0009] The pick-up plate is provided with a plurality of pick-up openings, the pick-up openings including a through opening and a limiting opening, the through openings being connected at their intersection, the diameter of the through openings being larger than the sealing ring, and a retaining ring being provided on a side of the limiting opening away from the clamping plate, the diameter of the retaining ring being smaller than the annular body;

[0010] The second sliding frame is provided with a first driving source for rotating the pickup unit;

[0011] The second slide is provided with a second driving source for sliding on the first slide.

[0012] Furthermore, the first slide includes a crossbeam and first slides arranged at both ends of the crossbeam, the first slide is located at one end of the second slide and is provided with at least one first sliding block, and the first slide is provided with a second sliding block on a side close to the door frame.

[0013] Furthermore, the second slide includes a U-shaped frame, the frame is rotatably arranged in the U-shaped frame, the joint between the frame and the U-shaped frame is provided with a first driving source, and the U-shaped frame is provided with a first slide rail in parallel on one side close to the first slide, and the first slide rail is slidably matched with the first slide.

[0014] Furthermore, the U-shaped frame is provided with a second driving source, which includes a step pulley and a second driving motor rotatably arranged at both ends of the U-shaped frame, a synchronous belt is provided between the step pulleys, and the synchronous belt is clamped on the first slide, wherein one of the step pulleys is connected to the second driving motor.

[0018] (1) The second driving source is used to drive the second slide to extend the entire pickup unit into the vulcanizer, and the through-port is accurately placed above the vulcanized rubber part. The lifting driving unit is used to control the second slide and the entire pickup unit to move downward, and the vulcanized rubber part is placed in the through-port. The first driving cylinder is used to act on the clamping plate to cooperate with the pickup plate to clamp the vulcanized rubber part, and then the second driving source is used to move the entire second slide out. The first driving source is then used to control the pickup unit to rotate, and the first driving cylinder is used to release the clamping effect of the clamping plate on the vulcanized rubber part. At this time, the vulcanized rubber part falls into the receiving box under the action of gravity, thereby realizing the pickup from the vulcanizer to the receiving box. In this process, mechanical pickup is achieved by replacing manpower with machinery, which improves the efficiency of pickup. At the same time, there is no need for staff to be close to the high-temperature vulcanizer, thereby reducing labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present invention will be described clearly and completely below with reference to the embodiments.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on their specific circumstances.

[0033] See attached Figure 1 , shown is the specific structure of the vulcanized rubber part, wherein the vulcanized rubber part includes an annular body 1, an open end of the annular body 1 is provided with a sealing ring 2, the diameter of the sealing ring 2 is larger than the annular body 1, and it now needs to be removed from the mold of the vulcanizer.

[0034] See attached Figure 2-10 , shown is a picking mechanism, including a door frame, wherein the door frame includes two parallel door posts 3, a door beam 4 is provided between the two door posts 3, a lifting drive unit is provided on the door beam 4, the lifting drive unit includes two second drive cylinders 21, the output ends of the two second drive cylinders 21 are connected to a first slide, the first slide includes a crossbeam 6, both ends of the crossbeam 6 are provided with a first slide plate 7, the lower end of the first slide plate 7 is provided with two first sliding blocks 9, a second slide plate 10 is vertically arranged on the side of the first slide plate 7 close to the door post 3, and a second slide plate 8 is provided on the side of the door post 3 close to the second slide plate 10, and a second slide rail 13 is provided on the position of the second slide plate 8 corresponding to the second slide rail 10. When in use, the entire first slide plate is driven to slide up and down along the second slide rail 13 by the second drive cylinder 21, and the second slide plate 8 and the second slide rail 13 improve the stability of the entire first slide plate when sliding;

[0035] The first slide is provided with a second slide by the first slide rail 12 along the direction perpendicular to the action of the output end of the second drive cylinder 21. The second slide includes a U-shaped frame 11. The end of the U-shaped frame 11 close to the first slider 9 is provided with a first slide rail 12. The first slide rail 12 slides with the first slider 9. One end of the U-shaped frame 11 is rotated to provide a pickup unit, wherein the driving unit includes a frame 14. A pickup plate 15 is fixedly provided at the bottom of the frame 14. A clamping plate 20 is movably provided above the pickup plate 15 in the frame 14. The four corners of the clamping plate 20 are provided with mounting openings, and each mounting opening is provided with a mounting opening. A first driving cylinder 5 is installed, and the output end of the first driving cylinder 5 is connected to the pickup plate 15. When the output end of the first driving cylinder 5 is extended during operation, since the pickup plate 15 is fixed, when the output end of the first driving cylinder 5 acts on the pickup plate 15, the pickup plate 15 will exert a reaction force on the first driving cylinder 5, so that the first driving cylinder 5 drives the clamping plate 20 to move away from the pickup plate 15. At this time, the distance between the pickup plate 15 and the clamping plate 20 is increased. When the output end of the first driving cylinder 5 is retracted, the clamping plate 20 moves closer to the pickup plate 15.

[0036] The pick-up plate 15 is provided with the same number of pick-up ports 16 as the vulcanized rubber parts in the vulcanizer, wherein the pick-up port 16 includes a through port 17 and a limit port 18, and the intersection of the through port 17 and the limit port 18 is connected. The diameter of the through port 17 is larger than the diameter of the sealing ring 2, and the limit port 18 can accommodate the annular body 1. A retaining ring 19 is provided on the side of the limit port 18 away from the clamping plate 20. The diameter of the retaining ring 19 is smaller than the annular body 1. When taking out the parts, the second driving cylinder 21 is first used to control the The entire second carriage and the pickup unit move down to just above the vulcanized rubber part, and the sealing ring 2 is placed in the through-hole 17. The pickup unit is then moved backward as a whole so that the annular body 1 reaches the limit opening 18 and rests on the retaining ring 19. The first drive cylinder 5 then controls the clamping plate 20 to approach the pickup plate 15 and press it onto the sealing ring 2. At this point, the vulcanized rubber part is removed from the vulcanizer under the clamping action of the pickup plate 15 and the clamping plate 20. Finally, the entire pickup unit is moved.

[0037] Furthermore, a first driving source is provided on the second slide, and the first driving source includes a first driving motor 22 connected to the axis of the frame 14, and the first driving motor 22 is installed on the U-shaped frame 11. When the entire pickup unit is removed from the vulcanizer, the first driving motor 22 is used to rotate the entire pickup unit, so that the vulcanized rubber part is in a forward tilted state. Finally, the first driving cylinder 5 controls the clamping plate 20 to release the clamping of the vulcanized rubber part. At this time, the vulcanized rubber part falls from the gap between the clamping plate 20 and the pickup plate 15 under the action of gravity to achieve the purpose of dropping the material.

[0038] It can be seen that the utility model realizes the removal of vulcanized rubber parts on the vulcanizer by mechanical means, replacing manual removal, which not only improves the efficiency and mechanization of removal, but also avoids the contact between the staff and the high-temperature vulcanizer, reducing labor intensity;

[0039] Furthermore, the second slide is also provided with a second driving source, which includes step pulleys 24 arranged at both ends of the U-shaped frame 11, and a synchronous belt 25 is provided between the two step pulleys 24, and the synchronous belt 25 is connected to the first slide 7. One of the step pulleys 24 is equipped with a second driving motor 23. When in use, the second driving motor 23 acts on the synchronous belt 25. Since the synchronous belt 25 is connected to the first slide 7 at this time, the synchronous belt 25 will act on the entire second slide to slide horizontally along the first slider 9, and the horizontal movement of the picking unit is realized through the sliding of the second slide.

[0040] The working principle of the utility model is as follows: when taking out the parts, the second driving motor 23 uses the synchronous belt 25 to drive the entire second slide and the taking-out unit to move to the top of the mold of the vulcanizer, and each through-hole 17 is located directly above the vulcanized rubber part. Then, the second driving cylinder 21 controls the first slide and the second slide to move downward and place the sealing ring 2 in the through-hole 17. Then, the second driving motor 23 drives the entire second slide and the taking-out unit to move backward so that the annular body 1 on the vulcanized rubber part is located in the limit hole 18. At this time, the annular body 1 just reaches the retaining ring 19, and then the first driving cylinder 5 is started to control the clamping plate 20 to approach the picking plate 15 and clamp the sealing ring 2. Then the second driving motor 23 controls the entire second slide to move out of the vulcanizer. Then the first driving cylinder 5 is used to drive the entire picking unit to rotate and make the vulcanized rubber part at a forward tilt angle. Then the first driving cylinder 5 is used to drive the clamping plate 20 away from the picking plate 15. At this time, the vulcanized rubber part falls from the gap between the clamping plate 20 and the picking plate 15 under the action of its own gravity.

[0041] The above description is only a preferred specific embodiment of the present invention and does not limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
