Description

Technical Field

[0001] The invention relates to the technical field of mechanical automation, and in particular to a seat back covering wire. Background Art

[0002] Cars have become a rigid need in people's lives. As the demand continues to increase, the demand for car seats has also increased greatly. In the process of seat production, in order to improve the comfort of the seat, the backrest needs to be covered.

[0003] At present, the covering of car seat backrests is mainly done manually. Although there are automatic covering machines, the covering of seat backrests with complex structures still needs to be done manually using fixed-position fixed fixtures. Due to the complicated covering procedures and the need for many processes, multiple handling or transfers are required in the middle, resulting in low operating efficiency. Multiple handling consumes manpower and material resources, and requires the storage of intermediate materials and semi-finished products, resulting in inventory waste. If one person completes all the processes of backrest covering and reduces intermediate handling and storage, it will result in high labor intensity and extremely low work efficiency, which is not worth the loss.

[0004] On the other hand, the fixtures used for fixed-post backrest wrapping are single and cannot be used for multiple models. When wrapping is required for multiple models or the backrests of multiple models are wrapped on the same production line, it will cause a lot of inconvenience and may also cause the production line to be suspended and the fixture of another model needs to be replaced. This not only consumes time, but also requires the preparation of multiple sets of fixtures, resulting in increased production costs, reduced work efficiency, and more consumption of resources. Summary of the invention

[0005] In view of the defects and shortcomings in the background technology, the present invention provides a seat back covering line for multiple types of vehicles, which can meet the beat production mode, achieve zero intermediate inventory, reduce intermediate production costs, reduce the material and manpower of intermediate transportation, and effectively improve work efficiency.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A multi-vehicle seat backrest covering line includes a support structure, a motor drive assembly, a transmission plate chain, a tensioning mechanism and a covering clamping device; the motor drive assembly and the tensioning mechanism are installed on the support structure, the support structure includes a bracket and a workbench, the workbench is installed on the bracket, and a circle of transmission plate chains connected end to end are laid around the upper and lower surfaces of the workbench, and the covering clamping device is installed on the transmission plate chain.

[0008] A further measure taken is that the covering clamping device includes a positioning mechanism and a turning mechanism.

[0009] Further measures taken are: the positioning mechanism includes a base, a support plate, a skeleton positioning pin and a positioning pin switching part, the support plate is installed on one side of the base, the skeleton positioning pin is installed on the top of the support plate through the positioning pin switching part, and is switched to the position of different models through the positioning pin switching part.

[0010] Further measures taken are: the positioning pin switching part includes a connecting piece and a spring rotating button, the skeleton positioning pin is fixedly connected to one end of the connecting piece, and the spring rotating button passes through the other end of the connecting piece and is rotatably connected to the top of the support plate.

[0011] Further measures taken are: the flipping mechanism includes an active flipping mechanism, which includes a rotating seat, a fixed concave-convex block and an unlocking handle, the fixed concave-convex block has multiple card positions, and is installed on the base close to the side of the support plate, one end of the unlocking handle passes through the base and the middle of the fixed concave-convex block and is connected to one side of the rotating seat, and the other side of the rotating seat is connected to the support plate, and the rotating seat is provided with a cam that cooperates with the card position on the side close to the fixed concave-convex block, and the cam is separated or engaged with the card position through the unlocking handle.

[0012] Further measures taken are: the active flipping mechanism also includes a locking part, which includes a lock body, a locking handle, a spring limit pin and a stop block. The lock body is installed on the top of the base, and the stop block is installed on the side of the support plate close to the base and located behind the lock body. The locking handle is installed on one end of the spring limit pin, and the other end passes through the lock body. When the rotating seat is combined with the fixed concave and convex block, the locking handle can be rotated to reach the stop block and fix the stop block.

[0013] Further measures taken are: the flipping mechanism also includes a driven flipping mechanism, the driven flipping mechanism includes a bearing and a fastener, the bearing is installed between the base and the support plate, the fastener passes through the support plate and the center of the bearing and is connected to the base, so that the support plate can be rotatably fixed on the base.

[0014] Further measures taken are: the driven flipping mechanism also includes a limit block, which is installed on the side of the base close to the support plate through a limit seat and is located at the bottom of the support plate close to the front and rear ends. The bottom of the support plate is cut into an arc segment. When the flipping angle of the driven flipping mechanism is too large, the bottom of the support plate rotates beyond the arc segment and will contact the limit block, causing it to be unable to rotate.

[0015] A further measure taken is that the transmission plate chain includes a transmission chain and a connecting plate between the transmission chains.

[0016] Further measures taken are: tool hanging strips are installed on the sides of the workbench, and side sealing nets are installed on the bottom edge.

[0019] 2) The present invention is provided with a positioning pin switching mechanism, which cooperates with the skeleton positioning pin through a connecting piece and a spring rotating knob to switch to positioning fixtures of different models, so that the covering fixture can quickly respond to the rapid production of multiple vehicle models switching between each other, thereby improving the utilization rate of the fixture, reducing production costs, improving production efficiency and saving production time.

[0020] 3) The present invention flexibly realizes the flipping of the seat back by providing an active flipping mechanism and a passive flipping mechanism, and performs production operations more flexibly to improve work efficiency. At the same time, a locking portion is provided to lock the flipping mechanism to improve the stability of the device. A limit seat is provided to limit the flipping angle so that it is not too large, which may easily cause loss of center of gravity or damage to the device, and the flipping mechanism is kept to improve the service life of the device.

[0021] 4) The present invention arranges tool hanging bars on the side of the workbench to facilitate the placement of tools, improve work efficiency, and avoid the loss of tools and parts; and installs side sealing nets on the bottom edge to protect the bottom transmission plate chain and clamps to avoid collision with surrounding objects and damage to the machine.

DETAILED DESCRIPTION

[0028] In order to more clearly understand the technical solution adopted by the present invention, the preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0029] Please refer to the attached Figures 1 to 5 As shown, a multi-type seat backrest covering line includes a support structure 1, a motor drive assembly, a transmission plate chain 2, a tensioning mechanism 3 and a covering clamping device 4; the motor drive assembly and the tensioning mechanism 3 are installed on the support structure 1, and the support structure 1 includes a bracket 101 and a workbench 102, the workbench 102 is installed on the support 101, and a circle of transmission plate chains 103 connected end to end are laid around the upper and lower surfaces of the workbench 102, and the covering clamping device 4 is installed on the transmission plate chain 103.

[0030] The covering clamping device 4 includes a positioning mechanism 5 and a flipping mechanism 6. The positioning mechanism 5 includes a base 501, a support plate 502, a skeleton positioning pin 503 and a positioning pin switching part 504. The support plate 502 is installed on one side of the base 501. The skeleton positioning pin 503 is installed on the top of the support plate 502 through the positioning pin switching part 504, and is switched to the position of different models through the positioning pin switching part 504; the positioning pin switching part 504 includes a connecting piece 505 and a spring rotating button 506. The skeleton positioning pin 503 is fixedly connected to one end of the connecting piece 505, and the spring rotating button 506 passes through the other end of the connecting piece 505 and is rotatably connected to the top of the support plate 502.

[0031] The flip mechanism 6 includes an active flip mechanism 7 and a driven flip mechanism 8; the active flip mechanism 7 includes a rotating seat 701, a fixed concave-convex block 702, a locking portion 703 and an unlocking handle 704, the fixed concave-convex block 702 has multiple card positions, and is installed on the base 501 close to the support plate 502. One end of the unlocking handle 704 passes through the middle of the base 501 and the fixed concave-convex block 702 and is connected to one side of the rotating seat 701, and the other side of the rotating seat 701 is connected to the support plate 502. The rotating seat 701 is provided with a cam that cooperates with the card position on the side close to the fixed concave-convex block 702, and The cam is separated or engaged with the locking position by unlocking the handle 704. The locking portion 703 includes a lock body 705, a locking handle 706, a spring limit pin 707 and a block 708. The lock body 705 is installed on the top of the base 501, and the block 708 is installed on the side of the support plate 502 close to the base 501 and is located behind the lock body 705. The locking handle 704 is installed on one end of the spring limit pin 707, and the other end passes through the lock body 705. When the rotating seat 701 is combined with the fixed concave and convex block 702, it can be rotated through the locking handle 706 to reach the block 708 and fix the block 708.

[0032] The driven flipping mechanism 8 includes a bearing, a limit block 802 and a fastener 801. The bearing is installed between the base 501 and the support plate 502. The fastener 801 passes through the support plate 502 and the center of the bearing to be connected to the base 501, so that the support plate 502 can be rotatably fixed on the base 501. The limit block 802 is installed on the side of the base 501 close to the support plate 502 through the limit seat 803 and is located at the bottom of the support plate 502 close to the front and rear ends. The bottom of the support plate 502 is cut into an arc segment 804. When the flip angle of the driven flipping mechanism 8 is too large, the bottom of the support plate 502 rotates beyond the arc segment 804 and will contact the limit block 802, making it unable to rotate.

[0033] The transmission plate chain 2 comprises a transmission chain 201 and a connecting plate 202 between the transmission chains. A tool hanging bar 103 is installed on the side of the workbench 102, and a side sealing net 104 is installed on the bottom edge.

[0034] When performing the covering operation on the car seat backrest, first debug the tensioning mechanism 3 and turn on the motor drive assembly to drive the transmission plate chain 2 for reflux transmission, then put the seat backrest on the fixture, and position the seat backrest through the skeleton positioning pin 503 on the positioning mechanism 5. The covering operation is carried out in different steps and processes. Operators of different jobs wait at the corresponding positions of the workbench 102 for the completion of the previous covering operation and flow to their own workstations, and then carry out the covering operation. The seat backrest can be covered in the backrest covering line for assembly line operation. The covering work of all seats can be completed in one step, reducing the intermediate transportation and storage, and effectively improving the working efficiency.

[0035] When covering the seat backs of different models, there is no need to replace the covering clamping device 4. It is only necessary to adjust the spring rotating knob 506 of the positioning pin switching part 504 and rotate the skeleton positioning pin 503 on the connecting part 505 to rotate the skeleton positioning pin 503 to the position of different models, thereby facilitating the covering operation of the backrests of various models on the same covering line, improving the utilization rate of the covering clamping device 4, saving production costs and improving working efficiency.

[0036] In order to better cover the backrest, the backrest needs to be turned over during the backrest covering process, which can be achieved through the turning mechanism 6. First, the locking handle 706 of the locking part 703 is rotated to rotate the spring stop pin 707 of the fixed block 708 back into the lock body 705, and the block 708 on the support plate 502 is released, and then the unlocking handle 704 is pushed to separate the fixed concave-convex block 702 from the rotating seat 701. Next, the operator slightly turns over the backrest to rotate the rotating seat 701, and the driven turning mechanism 8 also rotates accordingly; after rotating to a certain angle, the unlocking handle 704 is pulled, and the rotating seat 701 returns to its original position and combines with the fixed concave-convex block 72, and the cam is engaged with the fixed concave-convex block, thereby fixing the turning mechanism 6 and fixing the backrest at a certain turning angle.

[0037] In order to further fix the flipping mechanism 6, the locking handle 7006 can also be rotated, the spring limit pin 707 can be turned to the stop block 708 and the stop block 708 can be fixed, so as to further fix the active flipping mechanism 7; in addition, during the flipping process, the cooperation of the limit block 802 and the arc segment 804 of the driven flipping mechanism 8 can avoid the flipping angle of the flipping mechanism 6 being too large, and can also protect the wrapping clamping device 4 and increase the service life of the device; and the tool hanging strip 103 can facilitate the placement of wrapping working tools and parts, avoid the loss of tools and parts, and facilitate operation; the side sealing net 104 can protect the bottom transmission plate chain 2 and the clamp to avoid collision with surrounding objects and damage to the machine.

[0038] The above description is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary persons in the art should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
