[0033] It is understandable that the processing and assembly of parts are generally carried out on the main line, which can effectively improve the production efficiency of parts. During the transportation of parts on the main line, the main line is always in a conveying state and cannot be paused, but the parts need to be processed, assembled and tested.

[0034] In this case, the existing technology uses manual operation on the main line body to operate the parts, or uses robots to transfer the parts from the main line body, and then transport them back to the main line body after the relevant processes are completed. However, the manual operation on the main line body is labor-intensive, and due to the tight operation time, it is easy to make operational errors. In addition, the cost of using robots for transportation is high.

[0035] In order to solve the above problems, the utility model proposes a transfer device 100, which aims to solve the technical problems of the prior art that manual operation of parts on the main line body 1 is labor-intensive, prone to operating errors, and high robot handling costs.

Specifically, taking the example that the processing mechanism 2 includes one processing line body, the processing line body is arranged on one side of the two opposite sides of the main line body 1 in the second direction, and is used to receive the materials transported by the main line body 1, and perform processing such as caching, assembly, and testing on the received materials.

[0040] Further, in order to improve the convenience and efficiency of material processing, in the embodiments of the present utility model, please refer to Figure 1 and Figure 2 , the transfer device 100 also includes a transfer mechanism 3. The transfer mechanism 3 can be implemented by a transfer line body. The number of transfer lines is generally not limited.

The first transfer line 31 and the second transfer line 32 are extended along the second direction and spaced apart along the first direction, and the first processing line 21 is located between the first transfer line 31 and the second transfer line 32.

[0045] In the case of adding the second processing line 22, the third transfer line 33 and the fourth transfer line 34, in order to realize the reasonable layout of the second processing line 22, the third transfer line 33 and the fourth transfer line 34 without increasing the volume of the transfer device 100 too much, in the embodiment of the present utility model, please refer to Figure 1 The second processing line 22 is extended along the first direction, and the second processing line 22 and the main line 1 are spaced apart along the second direction.

[0049] There are many ways to implement the main line body 1. In the embodiments of the present utility model, please refer to Figure 1 and Figure 2The main line body 1 includes a feed line body section 11 and a discharge line body section 12. The feed line body section 11 has a first station 111, and the discharge line body section 12 has a second station 121. The first transfer line body 31 and the third transfer line body 33 are located on opposite sides of the first station 111, and the second transfer line body 32 and the fourth transfer line body 34 are located on opposite sides of the second station 121.

In addition, the materials processed by the first processing line body 21 and the second processing line body 22 can be transported back to the main line body 1 through the second station 121, so that the main line body 1 does not need to set a station for each of the first processing line body 21 and the second processing line body 22, thereby improving the structural compactness of the main line body 1.

[0050] Based on the above content, in order to realize the linkage use of the first transport line 31 and the third transport line 33, in the embodiment of the present utility model, please refer to Figure 1 and Figure 2 , one of the first transfer line 31 and the third transfer line 33 can move in a direction close to or away from the main line 1, driving the other of the first transfer line 31 and the third transfer line 33 to move in a direction close to or away from the first processing line 21 or the second processing line 22. For example, when the first transfer line 31 moves in a direction close to the main line 1, it can drive the third transfer line 33 to move in a direction close to the second processing line 22. At this time, the first transfer line 31 receives the material transported by the main line 1, and the third transfer line 33 transfers the received material to the second processing line 22 for processing, thereby realizing the simultaneous processing of two materials and improving the processing efficiency of batch materials.

[0051] Similarly, it can be inferred that in order to realize the linkage use of the second transport line body 32 and the fourth transport line body 34, in the embodiment of the present utility model, please refer to Figure 1 and Figure 2 , one of the second transfer line body 32 and the fourth transfer line body 34 can move in a direction close to or away from the main line body 1, driving the other of the second transfer line body 32 and the fourth transfer line body 34 to move in a direction close to or away from the first processing line body 21 or the second processing line body 22. For example, when the second transfer line body 32 moves in a direction close to the main line body 1, it can drive the fourth transfer line body 34 to move in a direction close to the second processing line body 22. At this time, the second transfer line body 32 transfers the processed materials to the main line body 1, and the fourth transfer line body 34 receives the materials transported by the second processing line body 22 for transfer, so as to realize the simultaneous transfer of two materials and improve the transfer efficiency of batch materials.

[0052] In one embodiment of the present invention, please refer to Figure 1 and Figure 2 The conveying speed of the feed line segment 11 is lower than the conveying speed of the discharge line segment 12. This is to ensure that after the processed materials enter the discharge line segment 12, they can be quickly separated from the materials in the feed line segment 11, thereby increasing the discharge speed of the product.

[0053] In one embodiment of the present invention, please refer to Figure 1 and Figure 2 The main line body 1 also includes a straight line body section 13, which is connected between the feed line body section 11 and the discharge line body section 12. By setting the straight line body section 13, when the processing equipment on both sides of the main line body 1 fails, since the processing equipment on both sides of the main line body 1 no longer performs transfer and processing actions, at this time, the material is transported to the straight line body section 13 through the feed line body section 11, and then transported to the discharge line body section 12 by the straight line body section 13, thereby ensuring the transportation of the material; when the processing equipment on one side of the two sides of the main line body 1 fails, the faulty side no longer performs transfer and processing actions, half of the material is transported as usual through the normal side, and the other half of the material is transported through the straight line body section 13, thereby ensuring the normal transportation of the overall material.
