Description

Technical Field

[0001] This utility model relates to the field of flexible pin collection technology, and in particular to a material collection structure for an assembly machine. Background Technology

[0002] The core structure of the elastic pin is mostly a hollow cylinder with a spring inside, which is used to insert into the pin hole of the detachable connector for positioning. It is mainly assembled by an assembly machine. The hollow cylinder and spring are conveyed and clamped to the turntable station of the assembly machine by a feeder and pressed together. Then the finished elastic pin is collected by the receiving structure.

[0003] Existing material receiving structures mainly use lifting pneumatic grippers to hold the elastic pins at the workstation and then directly transfer them to the inclined receiving trough for material collection. However, this method suffers from slippage speed loss and impact: after being gripped, the elastic pin is placed directly into the high-end inlet of the receiving trough. The elastic pin is accelerated by gravity, which can easily lead to slippage and impact with the bottom of the trough or the outlet, causing end deformation, wear and disintegration of the elastic pin, and thus affecting quality. To address these issues, we propose a material receiving structure for assembly machines to solve the problems encountered in existing technologies. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A material receiving structure for an assembly machine includes a fixed frame, in which a lifting pneumatic gripper and a material receiving trough are movably disposed. A damping element is disposed in the material receiving trough, and the damping element includes a silicone block. The silicone block is arranged in a spiral shape and its outer surface is provided with anti-slip particles.

[0007] In a preferred embodiment of the material receiving structure for an assembly machine described in this utility model, the material receiving trough is inclined, and a silicone block is embedded in the bottom wall of the material receiving trough, with the top of the silicone block flush with the bottom wall of the material receiving trough.

[0008] As a preferred embodiment of the material receiving structure for an assembly machine described in this utility model, the outer surface of the silicone block is integrally provided with anti-slip particles, the diameter of which is 10-50μm.

[0009] In a preferred embodiment of the material receiving structure for an assembly machine described in this utility model, the anti-slip particles are arranged in a hemispherical shape.

[0010] In a preferred embodiment of the material receiving structure for an assembly machine described in this utility model, the silicone blocks are arranged with a sparse front and a dense back, and the distance between the upper half of the silicone blocks is smaller than the distance between the lower half.

[0011] In a preferred embodiment of the material receiving structure for an assembly machine described in this utility model, the upper half pitch of the silicone block is 25-30cm.

[0012] In a preferred embodiment of the material receiving structure for an assembly machine described in this utility model, the lower half pitch of the silicone block is 10-15cm.

[0013] As a preferred embodiment of the material receiving structure for an assembly machine described in this utility model, the inner wall of the fixed frame is fixed with an electric slide rail by bolts, and the output end of the electric slide rail is fixed with a lifting pneumatic gripper for driving the lifting pneumatic gripper to move horizontally.

[0016] The beneficial effects of this utility model are as follows: This structure achieves graded buffering by using an inclined receiving groove in conjunction with a damping component with silicone blocks that are sparse in the front and dense in the back. Combined with anti-slip particles to increase friction, it solves the problems in existing receiving structures where the elastic pin falls directly into the inclined receiving groove and then loses control of its sliding speed due to gravity acceleration, and the impact on the groove body causes end deformation, wear and disintegration, thus ensuring the receiving quality of the elastic pin.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1:

[0028] Reference Figures 1 to 5 This is the first embodiment of the present utility model. This embodiment provides a material receiving structure for an assembly machine, including a fixed frame 1. A pneumatic gripper 2 of model G40.1 is movably installed in the fixed frame 1 to hold the elastic pin 10 in the upper station 9 of the turntable 8. A material receiving groove 3 is also movably installed in the fixed frame 1. A damping element 4 is installed in the material receiving groove 3. The damping element 4 includes a silicone block 41. The silicone block 41 is arranged in a spiral shape and the outer surface of the silicone block 41 is provided with anti-slip particles 42.

[0029] The movable lifting pneumatic gripper 2 moves to the upper station 9 of the turntable 8 to stably clamp the finished elastic pin 10, ensuring that the elastic pin 10 is smoothly transferred from station 9. The movable receiving trough 3 can be adjusted according to the actual receiving needs to ensure that the elastic pin 10 falls accurately to complete the receiving. The damping element 4 in the receiving trough 3 is used to slow down the downward speed of the elastic pin 10. The spiral arrangement of the silicone block 41 can extend the downward path of the elastic pin 10 in the receiving trough 3, further reducing the downward speed and preventing it from hitting the trough body due to excessive speed. The anti-slip particles 42 on the outer surface of the silicone block 41 can increase the friction with the elastic pin 10, help slow down the downward speed, and enhance the contact stability between the silicone block 41 and the elastic pin 10. Together, they prevent the elastic pin 10 from deforming, wearing or disintegrating at the end due to loss of control of the sliding speed during the receiving process, thus ensuring the quality of receiving.

[0030] It should be noted that when the silicone block 41 embedded in the bottom wall of the receiving trough 3 contacts the outer periphery of the elastic pin 10, the anti-slip particles 42 can increase the friction to restrict rolling. Moreover, the distribution of the silicone block 41, which is sparse in the front and dense in the back, can further constrain the movement trajectory of the elastic pin 10 through gradient buffering, ensuring that it slides down the trough in a directional manner rather than rolling randomly. The silicone block 41 is made of food-grade silicone with a Shore hardness of 50-60HA. This hardness range is highly versatile in mechanical buffering scenarios and has both elasticity and wear resistance. Under the action of 20N pressure, when the compression is 5mm, it rebounds to more than 90% of the initial height within 10s after the pressure is released. This ensures that when the weight of the elastic pin 10 is the common specification of 5-20g, when it contacts the silicone block 41, the silicone block 41 can produce an elastic deformation of 0.5-2mm, buffering the initial sliding speed of the elastic pin 10 from 0.3-0.5m / s to 0.15-0.2m / s. After deformation, it can rebound quickly without affecting the subsequent passage of the elastic pin 10. The friction coefficient of the anti-slip particles 42 can be stably maintained at 0.35-0.45. The combined effect of the two causes the sliding speed of the elastic pin 10 to decrease to 0.05-0.1m / s within 0.5s.

[0031] Example 2:

[0032] Reference Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Specifically, Figure 3 In the middle, the receiving trough 3 is made of plastic and is inclined. The bottom wall of the receiving trough 3 is fitted with silicone blocks 41 by means of inlay. The top of the silicone blocks 41 is flush with the bottom wall of the receiving trough 3.

[0034] The inclined structure of the receiving groove 3 provides downward force for the elastic pin 10, and the embedded and flush silicone block 41 can initially contact the elastic pin 10 to achieve buffering without hindering the downward movement, thus avoiding hard contact wear.

[0035] Specifically, Figure 5 In the middle, anti-slip particles 42 are integrally formed on the outer surface of the silicone block 41, and the diameter of the anti-slip particles 42 is 10-50μm. The anti-slip particles 42 are arranged in a hemispherical shape;

[0036] The hemispherical anti-slip particles 42 can increase the friction with the elastic pin 10, slow down the sliding speed, and the 10-50μm size is adapted to the anti-slip requirements of the elastic pin 10, avoiding the anti-slip particles 42 being larger than 50μm and hindering sliding or smaller than 10μm and failing.

[0037] Specifically, Figure 4 In the middle, the silicone blocks 41 are arranged with a sparser front and a denser back. The distance between the upper half of the silicone blocks 41 is 5cm, which is smaller than the distance between the lower half, which is 8cm. The pitch of the upper half of the silicone blocks 41 is 25-30cm. The pitch of the lower half of the silicone blocks 41 is 10-15cm.

[0038] The upper half is sparsely distributed to achieve initial buffering and avoid excessive initial descent speed. The lower half is densely distributed to further enhance the buffering effect. The gradient distribution gradually decelerates the speed and prevents the elastic pin 10 from losing control.

[0039] Example 3:

[0040] Reference Figure 1 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0041] Specifically, Figure 1 In the middle, the inner wall of the fixed frame 1 is fixed with an electric slide rail 5 by bolts, and the output end of the electric slide rail 5 is fixed with a lifting pneumatic gripper 2 for driving the lifting pneumatic gripper 2 to move horizontally. The inner wall of the fixed frame 1 is fixed with an electric telescopic rod 6 by bolts, and the output end of the electric telescopic rod 6 is fixed with a receiving trough 3 for driving the receiving trough 3 to move.

[0042] The electric slide rail 5 enables the lifting pneumatic gripper 2 to transfer the elastic pin 10, and the electric telescopic rod 6 facilitates the adjustment of the position of the receiving trough 3, improving the flexibility and accuracy of receiving materials.

[0043] Specifically, Figure 1 In the middle, the bottom wall of the fixed frame 1 is fixed with a rectangular frame 7 by rivets, and the rectangular frame 7 is located below the high-end inlet of the receiving trough 3;

[0044] The rectangular frame 7 collects the elastic pins 10 that accidentally fall off during the material receiving process, thus avoiding material waste and equipment jamming.

[0045] Working principle: First, the electric slide rail 5 drives the lifting pneumatic gripper 2 to move horizontally, so that the lifting pneumatic gripper 2 moves to the upper station 9 of the turntable 8 and clamps the finished product elastic pin 10. Then, the electric slide rail 5 directly drives the lifting pneumatic gripper 2 holding the elastic pin 10 to move to the high-end entrance of the receiving trough 3. The lifting pneumatic gripper 2 releases the elastic pin 10, and the elastic pin 10 falls directly into the receiving trough 3.

[0046] The elastic pin 10 first contacts the sparsely distributed silicone blocks 41 in the upper half of the receiving trough 3. The elasticity of the silicone blocks 41 can initially buffer the downward speed of the elastic pin 10 and reduce the impact force caused by gravity acceleration.

[0047] As the elastic pin 10 slides down to the densely distributed silicone blocks 41 in the lower half of the receiving trough 3, the denser silicone blocks 41 further enhance the buffering effect. At the same time, the anti-slip particles 42 on the outer surface of the silicone blocks 41 increase the friction between them and the elastic pin 10, further slowing down the sliding speed and preventing the elastic pin 10 from hitting the bottom of the trough or the outlet due to loss of control of the sliding speed.

[0048] In addition, the electric telescopic rod 6, which is fixed to the inner wall of the fixed frame 1 by bolts, can drive the receiving trough 3 to move, so that the operator can adjust the position of the receiving trough 3 according to the actual receiving needs and ensure that the elastic pin 10 falls stably.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
