[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0039] See also Figures 1 to 3 As shown, an embodiment of the present invention provides a product line variable speed transmission control system, which includes at least one operating line 1, a positioning mechanism 2, an operating mechanism 3 and at least one conveying line 4.

[0040] The operation line 1 is provided with an operation area, and the operation line 1 is configured to transport the product to be processed at a first speed. In this embodiment, the operation line 1 is a carrier line for line laying and automatic operation. After the product to be processed is transported to the operation area, it is fixed by the positioning mechanism 2 and then processed by the operation mechanism 3. Generally speaking, the operation line 1 can be a processing operation platform.

[0041] The positioning mechanism 2 is used to cooperate with the operation line 1 to fix the product to be processed in the operation area. In this embodiment, if a plane rectangular coordinate system is established with the operation surface of the operation line 1 as a reference, the positioning mechanism 2 is used to cooperate with the operation line 1 to fix the product to be processed in the X-axis direction and the Y-axis direction.

[0042] Preferably, the positioning mechanism 2 in this embodiment includes a support frame 21 and a positioning and fixing device 22 .

[0043] The support frame 21 is arranged between the working line 1 and the conveying line 4 and fixed on the working line 1, and a positioning gate 23 is arranged on the support frame 21. The positioning gate 23 is mainly used to constrain the position of the product to be processed in the Y-axis direction. When the positioning gate 23 is closed, the product to be processed will be prevented from being transmitted forward.

[0044] The positioning and fixing device 22 is arranged on the work line 1, and is used to cooperate with the positioning gate 23 and the work line 1 to fix the product to be processed in the work area. The positioning and fixing device 22 is mainly used to fix the product to be processed in the X-axis direction, which is mainly achieved by cooperating with the work line 1. Generally speaking, a baffle will be set on the work line 1. In this embodiment, a baffle setting scheme for a single work area is given, that is, an S-shaped baffle 11 is provided on the work line, and the baffle 11 is arranged so that the feed port of the work line 1 is larger than the discharge port. With such a setting method, both the situation of a single work area and the feed amount can be taken into account. It is understandable that it can also be set as a double work area. In this case, the baffle can be set in the middle of the work line 1, and another positioning and fixing device 22 can be configured on the other side of the work line 1.

[0045] It is worth noting that the product line variable speed transmission control system in this embodiment also includes a control mechanism, which communicates with the positioning gate 23, the operation line 1 and the positioning and fixing device 22 by means of signal connection. When the positioning gate 23 detects that the product to be processed has arrived at the preset position, it sends a signal to the control mechanism, and the control mechanism drives the operation line 1 to stop transmission and activates the positioning and fixing device 22 to fix the product to be processed.

[0046] Preferably, a sensor may be provided at the positioning gate 23 to determine whether the product to be processed has reached the preset position, for example, by determining whether the product to be processed has hit the positioning gate 23 through the sensor.

[0047] As a better implementation, in some embodiments, the positioning and fixing device 22 includes a fixed end 221 and a hydraulic rod 222. The fixed end 221 is fixed to the work line 1, one end of the hydraulic rod 222 is fixed to the fixed end, and the other end is provided with a clamping plate 223 for clamping the product to be processed. In this way, the adjustment and positioning of the product to be processed in the X-axis direction can be achieved by extending and retracting the hydraulic rod 222.

[0048] The operating mechanism 3 is disposed at one side of the operating area and is used to process the product to be processed after being fixed by the positioning mechanism 2. In this embodiment, the operating mechanism 3 is an operating robot.

[0049] The conveyor line 4 is disposed adjacent to the operating line 1 , and the conveyor line 4 is configured to transmit the processed products processed by the operating mechanism at a second speed, and the second speed is greater than the first speed.

[0050] As a preferred embodiment, the second speed is three times the first speed. It is understandable that this embodiment does not limit this. In the actual production process, the speed relationship between the second speed and the first speed can be flexibly set according to the actual situation to find a balance between economy and efficiency. In addition, the transmission length of the transmission line 4 in this embodiment is 0.8 to 1.2 meters. Of course, its transmission length can also be determined according to demand.

[0051] Furthermore, the number of the operating lines 1 and the conveying lines 4 included in the product line speed transmission control system can also be set according to the requirements. Figure 1 As shown, for example, another operation line 1 can be set at the other end of the conveyor line 4 to deploy manual operations or the next automatic operation. It is understandable that another conveyor line 4 can be set after the newly added operation line 1, which can be reasonably set according to the number and type of workstations.

[0052] In summary, the product line different speed transmission control system in the present invention is to divide the original overall assembly line into several short lines according to demand through the interval setting of the operation line 1 and the transmission line 4, wherein the transmission speed of the transmission line 4 is greater than that of the operation line 1, so as to form a combination mode of slow line and fast line, that is, the operation is carried out on the operation line 1 as the slow line, and the product is quickly taken away from the automatic operation station by the transmission line 4 as the fast line. By balancing the line speed, more dense workpieces can be placed on the operation line 1, reducing the difficulty of laying out the line, and effectively improving the utilization efficiency of the operation station.

[0053] At the same time, the present invention also provides a product line different speed transmission control method using the above product line different speed transmission control system, the method comprising the following steps:

[0054] The product to be processed is transported at a first speed by the operation line 1. When the product to be processed is located in the operation area, the positioning mechanism 2 cooperates with the operation line 1 to fix the product to be processed in the operation area. The product to be processed in the operation area is processed by the operation mechanism 3, and the processed product processed by the operation mechanism is transported by the conveyor line 4 at a second speed greater than the first speed, so that the processed product leaves the operation line 1 at an accelerated speed.

[0055] The product line differential speed transmission control method of the present invention divides the original overall assembly line into a number of short lines as required by setting the operation line 1 and the transmission line 4 at intervals, thereby forming a combination mode of slow lines and fast lines. By balancing the line speed rhythm, more densely packed workpieces can be placed on the operation line 1, reducing the difficulty of laying out the lines and effectively improving the utilization efficiency of the operation stations.
