[0031] 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 of 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.

[0032] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] Reference Figures 1 to 5 , the X direction shown in the figure is the first direction, and the Y direction shown in the figure is the second direction.

[0034] The utility model embodiment provides an assembly line device, including: a main conveying mechanism, including a first conveying component 1, the first conveying component 1 performs a conveying movement along a first direction, the first conveying component 1 includes at least one main conveying unit, an auxiliary conveying mechanism, including a second conveying component 2 and a pressing component 3, the second conveying component 2 and the first conveying component 1 are arranged relative to each other up and down, the second conveying component 2 performs a conveying movement along the first direction, the pressing component 3 is arranged on a side of the second conveying component 2 away from the first conveying component 1, the second conveying component 2 includes at least one auxiliary conveying unit, the pressing component 3 drives the auxiliary conveying unit to perform a lifting movement, and the auxiliary conveying unit and the main conveying unit jointly clamp the workpiece to convey the workpiece along the first direction. Reference Figures 1 to 7 According to the relationship between the upper and lower workstations on the assembly line, the direction of transfer from the upstream position to the downstream position is defined as the first direction. A first transmission component 1 is arranged on the processing machine frame 7. The first transmission component 1 transmits the workpiece along the first direction. The first transmission component 1 is composed of a first main delivery unit 11 and a second main delivery unit 12. A second transmission component 2 is arranged above the first transmission component 1. The second transmission component 2 is composed of a first auxiliary delivery unit 21 and a second auxiliary delivery unit 22. A pressing component 3 is arranged above the second transmission component 2. The pressing component 3 is responsible for driving the second transmission component 2 to perform an ascending and descending action. When the second transmission component 2 and the first transmission component 1 clamp the workpiece together, the two transmission components simultaneously transmit the workpiece along the first direction. For example, when workpieces A and B enter the device from the upstream of the assembly line, workpiece A is transported to the second main delivery unit 12 via the first main delivery unit 11, and the second main delivery unit 12 then transports workpiece A to the center of the second main delivery unit 12, and workpiece B is transported from the first main delivery unit 11 to the center of the first main delivery unit 11, and workpieces A and B are stationary, the pressing assembly 3 presses down the second transport assembly, and the distance between the first auxiliary delivery unit 21 and the first main delivery unit 11 is shortened until the workpiece B is clamped, and the distance between the second auxiliary delivery unit 22 and the second main delivery unit 12 is shortened. The distance is shortened until the workpiece A is clamped. When workpieces A and B need to be moved on the assembly line again after completing the processing flow, the second auxiliary conveying unit 22 and the second main conveying unit 12 move in the first direction while clamping workpiece B, and the first auxiliary conveying unit 21 and the first main conveying unit 11 move in the first direction while clamping workpiece A. At this time, since the pressing assembly 3 presses down the second transport assembly, the force applied to the workpiece is less than the maximum static friction of the workpiece, so that the workpiece will not slip during the acceleration process, and thus no relative position shift will occur.

[0035] In this embodiment, the second transport assembly is moved up and down by using a pressing device, so that the first auxiliary conveying unit 21 and the second auxiliary conveying unit 22 clamp the workpiece with the first main conveying unit 11 and the second main conveying unit 12 respectively, so that by applying sufficient pressure, the workpiece will not slip due to insufficient friction when it is restarted after being processed in a stationary state, and then there will be no positional deviation, thereby ensuring that the assembly line can run at a higher speed and improving the production efficiency of the assembly line.

[0036] In one embodiment, referring to Figure 1 and 4 The pressing assembly 3 includes a linear motion driving source and a support plate 37. The support plate 37 is arranged above the auxiliary feeding unit. The linear motion driving source is fixed on the support plate 37. The linear motion driving source includes a moving head 39. The moving head 39 is connected to the auxiliary feeding unit and performs lifting and lowering motion. The pressing assembly 3 includes a first linear motion driving source 31 and a second linear motion driving source 34, and also includes a support plate 37. The support plate 37 is connected and fixed to the processing machine frame 7. The function of the linear motion driving source is to drive the auxiliary feeding unit to move downward to clamp the workpiece. The linear motion driving source can be an electric cylinder or a pneumatic cylinder. The linear motion driving source includes a first linear motion driving source 31 and a second linear motion driving source 32. The front end of the upper moving part of the linear motion driving source is called the moving head 39. The moving head 39 is connected to the auxiliary feeding unit, and it directly drives the auxiliary feeding unit to perform lifting and lowering motion to achieve the clamping action. In particular, in order to reduce the influence of the inevitable shaking of the moving head of the linear motion driving source during operation on the auxiliary feeding unit, the moving head 39 is generally connected to the auxiliary feeding unit by a hinge.

[0037] In one embodiment, referring to Figure 1 and 4 The pressing assembly 3 also includes a linear motion guide and a follower. The linear motion guide is vertically fixed on the support plate 37. The follower is connected to the auxiliary delivery unit. The follower can be slid up and down on the linear motion guide. The pressing assembly is also equipped with a first linear motion guide 32 and a second linear motion guide 35. The two linear motion guides are respectively equipped with a first follower 33 and a second follower 36 that can slide on the guides. The linear motion guide is vertically fixed to the support plate 37. The first follower 33 and the second follower 36 are respectively connected to the first auxiliary delivery unit 21 and the second auxiliary delivery unit 22. The above structure can maintain the stability of the movement when the first linear motion driving source 31 and the second linear motion driving source 32 drive the first auxiliary delivery unit 21 and the second auxiliary delivery unit 22 to move up and down, and can also make the force applied by the first auxiliary delivery unit 21 and the second auxiliary delivery unit 22 on the workpiece more uniform.

[0038] In one embodiment, referring to Figure 1 and 4The assembly line equipment of the utility model further includes a guide assembly 5, a processing area 6 is provided between the main feeding unit and the auxiliary feeding unit, and the guide assembly 5 is arranged on both sides of the processing area 6 along the first direction. Due to the inevitable vibration and deviation during the operation of the assembly line equipment, the workpiece may be in a position state not suitable for processing when it arrives at the processing area 6. Therefore, it is necessary to provide guide assemblies 5 on both sides of the processing area 6. Through the guide assembly, the workpiece that is fed along the first direction and guided to the processing area 6 can be corrected in shape and position before entering the processing area 6, thereby reducing the processing error and improving the operation efficiency of the assembly line.

[0039] Further, refer to Figure 1 , 3 4, the guide assembly 5 includes a station positioning frame 51 and a guide back frame 53, the station positioning frame 51 and the guide back frame 53 are arranged on both sides of the processing area 6 along the first direction, and the station positioning frame 51 is arranged with a guide motor 52, and the guide motor 52 pushes and pulls the station positioning frame 51 in the left and right directions along the first direction. When the product only needs single-sided processing but has higher processing accuracy requirements, it is necessary to arrange a set of guide assemblies 5 that are conducive to single-sided processing on it. For example, if the workpiece needs to be processed at the front end of the second direction, then a station positioning frame 51 is arranged at the front end of the processing area 6 along the second direction, and a guide frame 53 is arranged at the rear end of the processing area 6 along the second direction. The guide frame 53 is connected to the processing machine frame 7, and the station positioning frame 51 is movably connected to the processing machine frame 7. A guide motor 52 is arranged on the left side of the station positioning frame 51 to push the station positioning frame 51 to guide the frame 53 along the second direction, thereby changing the distance between the station positioning frame 51 and the guide frame 53, so as to realize the alignment operation of the workpiece in the processing area 6, so as to facilitate processing. In some special cases, the station positioning frame 51 can also be pushed by the guide motor 52 to move along the second direction during the processing to press the workpiece on the guide frame 53, so as to increase the stability of the workpiece during the processing, thereby improving the processing accuracy and facilitating further automation.

[0040] In particular, refer to Figure 1 , 3and 4, the guide back frame 53 includes a plurality of supporting bars 54 and a guiding structure 55 arranged side by side, the supporting bars 54 extending along the first direction, and the guiding structure 55 arranged at the front and rear ends of the supporting bars 54 extending along the first direction. The guide back frame 53 is composed of a plurality of supporting bars 54, which are arranged horizontally and arranged up and down along the first direction, and a guiding structure 55 is arranged at the edge of each supporting bar 54, and the guiding structure 55 can guide the workpiece with position deviation transmitted from the front end of the first direction. The guide back frame 53 is designed to be composed of a plurality of supporting bars 54 arranged longitudinally, which is helpful for disassembling and replacing the supporting bars 54 when processing workpieces of different heights and sizes, so that the supporting bars 54 with different guiding structures 55 can be installed according to the needs of various different workpieces, so that the application of the assembly line equipment is more diversified.

[0041] In one embodiment, referring to Figure 2 and 5 The assembly line equipment of the utility model also includes a feed transmission mechanism 4, which is arranged along the first direction and located at the front end of the first transmission, and the feed transmission mechanism 4 includes at least one feeding unit. A first feeding unit 41 and a second feeding unit 42 are arranged on the feed frame 8 of the feed transmission mechanism 4, the first feeding unit 41 is composed of a first feeding motor 411 and a first belt line 412, the second feeding unit 42 is composed of a second feeding motor 421 and a second belt line 422, the first feeding motor 411 drives the first belt line 412 to start and stop operation, and the second feeding motor 421 drives the second belt line 422 to start and stop operation, the feed transmission mechanism 4 is arranged before the first transmission component 1, and is used to buffer the workpieces sent from the upstream, providing a buffer zone for the assembly line equipment of the utility model.

[0042] Further, refer to Figure 1 , 2, 4 and 5, the assembly line equipment of the utility model also includes a sensor 9 and a PLC (not shown in the figure). The sensor 9 is arranged on the first transmission component 1 and / or the feed transmission mechanism 4. The sensor 9 is connected to the PLC. The PLC controls the operation of the main feeding unit, the auxiliary feeding unit, the pressing component 3 and the feeding unit according to the information collected by the sensor 9. Sensors 9, such as through-beam sensors 9, are arranged on both sides above the first belt line 412, the second belt line 422, the third belt line 112 and the fourth belt line 122. The status of whether there is a product occupying the corresponding belt line is obtained by the sensor 9, and the stacking status in the current equipment is identified. The information obtained by the sensor 9 is transmitted to the PLC unit. The PLC will operate each motor and electric cylinder on the equipment according to the preset operation program based on the information obtained, so as to realize the self-feedback speed regulation of the equipment. For example, when it is recognized that the sensor 9 on the third belt line 112 and the fourth belt line 122 obtains information that the processing area 6 is in a processing state and is occupied by a workpiece, the PLC controls the first feeding motor 411 and the second feeding motor 421 to drive the first belt line 412 and the second belt line 422 to slow down or stop to wait for the downstream processing area 6 to complete the processing action. For another example, when the sensor 9 on the third belt line 112 and the fourth belt line 122 obtains information that the processing area 6 is in an idle state, the PLC controls the first feeding motor 411 and the second feeding motor 421 to drive the first belt line 412 and the second belt line 422 to accelerate to shorten the waiting time for feeding the processing area 6, thereby improving the efficiency of the assembly line.

[0043] Further, refer to Figure 5 , the feeding unit includes a first belt line 412 and a second belt line 422, the main feeding unit includes a third belt line 112 and a fourth belt line 122, the line speed of the first belt is the first line speed, the line speed of the second belt is the first line speed, the line speed of the third belt is the third line speed, the line speed of the fourth belt is the fourth line speed, the first line speed is less than the second line speed, the second line speed is less than the third line speed, and the third line speed is less than the fourth line speed. In order to further improve the efficiency of the assembly line, it is necessary to have different transport beats between the first belt line 412, the second belt line 422, the third belt line 112 and the fourth belt line 122 to shorten the waiting interval. The line speed of the fourth belt line 122 at the end of the equipment is the most critical speed that affects the flow of the workpiece out of the equipment. Therefore, the fourth line speed of the fourth belt line 122 should be the largest among the line speeds of the various belt lines of the equipment, followed by the third line speed of the third belt line 112, followed by the second line speed of the second belt line 422, and finally the first line speed of the first belt line 412. For example, the first line speed is 40Hz, the second line speed is 47Hz, the third line speed is 54Hz, and the fourth line speed is 61Hz. The setting of the line speed is determined by the product structure, size, and the rhythm of the post-process work. The line speed of each section is not a fixed value. Different products may use different line speeds, but the purpose is to optimize the production rhythm of the assembly line and reduce the waiting time of the bottleneck position.

[0044] In one embodiment, an elastic structure is arranged between the moving head 39 and the connection position of the auxiliary feeding unit to play a role of buffering and shock absorption when processing some workpieces whose appearance needs to be protected or are easily damaged, thereby reducing the possibility of mechanical movement causing damage to the appearance of the workpiece and improving the product quality.

[0045] In one embodiment, the first main conveying unit 11 includes a third belt line 112 that is in direct contact with the workpiece and provides power for transfer, and a first main conveying motor 111 for driving the third belt line 112 to operate. The second main conveying unit 12 includes a fourth belt line 122 that is in direct contact with the workpiece and provides power for transfer, and a second main conveying motor 121 for driving the fourth belt line 122 to operate. The third belt line 112 and the fourth belt line 122 are arranged adjacent to each other end to end along a first direction. The first auxiliary conveying unit 21 includes a first auxiliary conveying belt line 212 and a first auxiliary conveying motor 211 that drives the first auxiliary conveying belt line 212. The second auxiliary conveying unit 22 includes a second auxiliary conveying belt line 222 and a second auxiliary conveying motor 221 that drives the second auxiliary conveying belt line 222. The pressing assembly 3 includes a first linear motion driving source 31, a first linear motion guide rail 32, a first follower 33, a second linear motion driving source 34, a second linear motion guide rail 35, a second follower 36, a support plate 37 and a guide column 38. The processing machine frame 7 and the support plate 37 are connected and fixed. The first linear motion driving source 31 and the first linear motion guide rail 32 are a group installed and fixed on the support plate 37. The first follower 33 can be slidably mounted on the first linear motion guide rail 32 up and down. The lower end of the first follower 33 is connected to the upper end of the first auxiliary delivery unit 21. The first linear motion driving source 31 and the second linear motion driving source 34 are electric cylinders. There is a moving head 39 at the end of the electric cylinder. The moving head 39 is connected to the upper end of the first auxiliary delivery unit 21. The moving head 39 drives the first auxiliary delivery unit 21 to move up and down under the action of the electric cylinder. It can be adjusted according to actual production conditions. The first linear motion driving source 31 and the second linear motion driving source 34 can also use cylinders. The relationship between the second linear motion driving source 34, the second linear motion guide rail 35, the second follower 36 and the second auxiliary delivery unit 22 is the same as that between the first linear motion driving source 31, the first linear motion guide rail 32, the first follower 33 and the first auxiliary delivery unit 21, so it will not be repeated here. The first linear motion driving source 31 and the second linear motion driving source 34 work independently of each other, which makes it unnecessary for the workpiece A and the workpiece B to flow into and out of the assembly line equipment of the embodiment of the utility model at the same time, reduces the front end stacking, and further improves the efficiency of the assembly line. At the same time, the pressing height between the first linear motion driving source 31 and the second linear motion driving source 34 can be different, so that the first processing area 6 and the second processing area 6 can respectively process products of different heights or types, making the assembly line equipment of the utility model more diversified.

[0046] In order to further illustrate the working principle of the assembly line equipment of this embodiment, it is described below in the form of a processing flow sequence.

[0047] First, when there is no workpiece above all the belt lines, workpiece A is transferred from the upstream station of the assembly line equipment of the utility model to the first belt line 412, and workpiece A passes through the second belt line 422 and the third belt line 112 in sequence along the first direction to reach the fourth belt line 122. After the sensor 9 on the fourth belt line 122 detects that the workpiece is in place, the PLC issues an instruction to stop the operation of the fourth belt line 122. The PLC issues an instruction to the second linear motion driving source 34, and the moving head 39 on the second linear motion driving source 34 moves downward to drive the second auxiliary conveying unit 22 to press down, and the second auxiliary conveying belt line 222 and the fourth belt line 122 are clamped to the workpiece at the same time. At the same time, workpiece B is transferred from the upstream station of the assembly line equipment of the utility model to the first belt line 412, and workpiece B passes through the second belt line 422 in sequence along the first direction to reach the third belt line 112. After the sensor 9 on the third belt line 112 detects that the workpiece is in place, the PLC issues an instruction to stop the operation of the fourth belt line 122. The PLC issues an instruction to the first linear motion drive source 31, and the moving head 39 on the first linear motion drive source 31 moves downward to drive the first auxiliary conveying unit 21 to press down, and the first auxiliary conveying belt line 212 and the third belt line 112 are clamped to the workpiece at the same time. After workpiece A and workpiece B are clamped up and down, the guide motor 52 drives the station positioning frame 51 to push workpiece A and workpiece B to the guide back frame 53, so that workpiece A and workpiece B are fixed horizontally, and then the processing flow of workpiece A and workpiece B is started. In this process, workpiece C and workpiece D are transferred from the upstream station of the assembly line equipment of the utility model and are stacked and cached on the second belt line 422 and the first belt line 412 respectively, waiting for the processing to be completed. When workpiece B and workpiece A are processed, the guide motor 52 drives the station positioning frame 51 to return to the original position, the second auxiliary conveying belt line 222 and the fourth belt line 122 run simultaneously to drive workpiece A from a stationary state to a moving state, and push workpiece A into the downstream station, and then the moving head 39 on the second linear motion driving source 34 pulls up to drive the second auxiliary conveying unit 22 to return to the original position, the first auxiliary conveying belt line 212 and the third belt line 112 run simultaneously to drive workpiece A from a stationary state to a moving state, and the moving head 39 on the first linear motion driving source 31 pulls up to drive the first auxiliary conveying unit 21 to return to the original position. After that, workpiece C and workpiece D are respectively transferred to the fourth belt line 122 and the third belt line 112, and the above processing flow is repeated.

[0048] The utility model also provides an assembly line processing device, which comprises the assembly line equipment in the above embodiment.

[0049] The use of the above-mentioned assembly line processing device can improve the efficiency of processing production, improve the processing accuracy, and improve the quality of the finished product.
