As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0030] In order to better understand the technical solutions and beneficial effects of the disclosure, the disclosure will be further described in detail below in combination with specific embodiments:

[0031] Please refer to Figure 1 which is a seat cover sewing needle device 10 of an embodiment of the utility model.

[0032] In combination with Figures 2 to 6As shown, the seat cover sewing device 10 comprises a sewing platform 100, a sewing head 200, a moving mechanism 300, a plurality of clamp buckles 400 and a seat cover fixing assembly 500. The sewing head 200 is fixed on the sewing platform 100, and the sewing part of the sewing head 200 is arranged towards the sewing platform 100. The moving mechanism 300 comprises a transverse driving cylinder (not shown), a transverse moving rod 310, a longitudinal driving cylinder (not shown), a longitudinal moving rod 320 and a transverse sliding rail 330. The sewing platform 100 is provided with a longitudinal sliding groove 101. The transverse driving cylinder and the longitudinal driving cylinder are both located in the sewing platform 100. The transverse moving rod 310 is movably arranged on the transverse sliding rail 330. The driving end of the transverse driving cylinder is connected with the transverse moving rod 310 to drive the transverse moving rod 310 to move along the transverse sliding rail 330. The longitudinal moving rod 320 is located in the longitudinal sliding groove 101. The transverse sliding rail 330 is fixedly connected with the longitudinal moving rod 320. The driving end of the longitudinal driving cylinder is connected with the longitudinal moving rod 320 to drive the longitudinal moving rod 320 to move in the longitudinal sliding groove 101, and then the longitudinal moving rod 320 drives the transverse sliding rail 330 to move. Each clamp buckle 400 comprises a stationary block 410, a moving block 420 and a buckle driving cylinder 430. The driving end of the buckle driving cylinder 430 is connected with the moving block 420. The stationary block 410 and the buckle driving cylinder 430 are both arranged on the transverse moving rod 310. The buckle driving cylinder 430 and the stationary block 410 form a buckle groove 400a. The seat cover fixing assembly 500 comprises a bottom plate 510, a fixing clamp 520, a plurality of fixing columns 530, an adhesive (not shown), a seat cover piece 540 and a buckling strip. The adhesive is arranged on the bottom plate 510. The buckling strip is arranged on the adhesive. The seat cover piece 540 covers the buckling strip and the adhesive and is arranged on the bottom plate 510. The fixing clamp 520 clamps the seat cover piece 540. The plurality of fixing columns 530 are connected with the bottom plate 510 and located in the corresponding buckle groove 400a. When the buckle driving cylinder 430 drives the moving block 420 to close the moving block 420 and the stationary block 410, the fixing columns 530 abut against the stationary block 410, the moving block 420 and the buckle driving cylinder 430 respectively, so that the clamp buckle 400 is fixedly connected with the bottom plate 510 through cooperation with the fixing columns 530. It can be understood that before the bottom plate 510 is pushed, the moving block 420 and the stationary block 410 are in a separated state, i.e. the clamp buckle 400 is in an unlocked state. After the fixing clamp 520 is actuated to clamp the seat cover piece 540, a hand pushes the bottom plate 510 to make the fixing columns 530 enter the buckle groove 400a, and then the buckle driving cylinder 430 drives the moving block 420 to close the moving block 420 and the stationary block 410. At this time, the periphery of the fixing columns 530 abuts against the moving block 420, the stationary block 410 and the buckle driving cylinder 430 respectively, thereby fixing the bottom plate 510 and preventing the fixing columns 530 from being separated from the buckle groove 400a in subsequent sewing.

[0033] In the embodiment, the seat cover sewing device 10 corresponds to the actual diagram as shown in Figure 7 The seat cover sewing device 10 adopts the clamp buckle 400, which is installed on the transverse moving rod 310. The seat cover fixing assembly 500 has fixing columns 530. When the buckle strip and the seat cover piece 540 are fixed and installed, the moving bottom plate 510 is moved so that the fixing columns 530 are located in the corresponding buckle slot 400a. Then, the machine is operated so that the buckle driving cylinder 430 drives the moving block 420 to close, so that the clamp buckle 400 buckles the fixing column 530. Therefore, when the machine performs the sewing step, the seat cover piece 540 will not be offset under the action of the fixing clamp 520, and the bottom plate 510 will not be offset under the action of the clamp buckle 400. In this way, the seat cover sewing device 10 does not need to move by needle and does not need manpower. In the case that the clamp buckle 400 buckles the fixing column 530, the bottom plate 510 is moved only by the cooperation of the transverse moving rod 310 and the longitudinal moving rod 320. During this period, the side walls of the fixing column 530 abut against the stationary block 410, the moving block 420 and the buckle driving cylinder 430, respectively. When the sewing step is performed, the bottom plate 510 is not easy to be separated from the clamp buckle 400.

[0034] It can be understood that before the seat cover fixing assembly 500 is placed, the clamp buckle 400 is in an unlocked state and does not buckle the fixing column 530. The state diagram is as shown in Figure 1 When the seat cover fixing assembly 500 is pushed until the fixing column 530 is located in the buckle slot 400a, the clamp buckle 400 plays a role of preliminary limiting. The state diagram is as shown in Figure 5 Then, the buckle driving cylinder 430 is controlled by computer operation to drive the moving block 420, so that the moving block 420 is buckled with the stationary block 410 to seal the opening of the buckle slot 400a, so that the clamp buckle 400 buckles the fixing column 530. The state diagram is as shown in Figure 4

[0035] In the embodiment, the number of the clamp buckle 400 is equal to the number of the fixing column 530.

[0036] Further, the transverse moving rod 310 and the longitudinal moving rod 320 are vertically arranged. It can be understood that, as shown in Figure 2 When the transverse moving rod 310 and the longitudinal moving rod 320 are vertically arranged, the upper part of the sewing platform 100 is taken as a horizontal plane, the moving direction of the transverse moving rod 310 coincides with the direction of the X axis (horizontal axis), and the moving direction of the longitudinal moving rod 320 coincides with the direction of the Y axis (vertical axis). In this way, when the seat cover is sewn, the moving distance of the bottom plate 510 in the X axis and the Y axis can be directly observed.

[0037] ​In one embodiment, both the stationary block 410 and the locking drive cylinder 430 are mounted on the side of the transverse moving rod 310. In this embodiment, since a locking groove 400a is formed between the locking drive cylinder 430 and the stationary block 410, and the locking groove 400a is also located on the side of the transverse moving rod 310, after the car seat material is installed, the base plate 510 is moved horizontally on the sewing platform 100 until the fixing post 530 enters the locking groove 400a, without the need to move the base plate 510 up and down.

[0038] like Figure 4 As shown, in one embodiment, the longitudinal moving rod 320 includes a first longitudinal moving rod 321 and a second longitudinal moving rod 322, and the longitudinal slide groove 101 includes a first longitudinal slide groove 1011 and a second longitudinal slide groove 1012. The first longitudinal moving rod 321 is located in the first longitudinal slide groove 1011, and the second longitudinal moving rod 322 is located in the second longitudinal slide groove 1012. The transverse slide rail 330 is fixedly connected to the first longitudinal moving rod 321 and the second longitudinal moving rod 322 respectively, so that the first longitudinal moving rod 321 and the second longitudinal moving rod 322 jointly support the transverse slide rail 330. The driving end of the longitudinal drive cylinder is connected to the first longitudinal moving rod 321. Since both the first longitudinal moving rod 321 and the second longitudinal moving rod 322 are fixedly connected to the transverse slide rail 330, when the longitudinal drive cylinder drives the first longitudinal moving rod 321 to move a certain distance in the first longitudinal slide groove 1011, the second longitudinal moving rod 322 follows and moves a certain distance in the second longitudinal slide groove 1012, thereby realizing the movement of the base plate 510 on the Y-axis. In another embodiment, the drive end of the longitudinal drive cylinder is connected to the first longitudinal moving rod 321 and the second longitudinal moving rod 322, respectively.

[0039] Furthermore, the lateral moving rod 310 is perpendicular to the first longitudinal moving rod 321, and the lateral moving rod 310 is perpendicular to the second longitudinal moving rod 322.

[0040] In one embodiment, the number of fixing clips 520 is greater than or equal to three, to ensure that each fixing clip 520 can properly hold the seat piece 540.

[0041] like Figure 5 As shown, in one embodiment, multiple retaining clips 520 are arranged toward the center portion of the base plate 510, so that the multiple retaining clips 520 form a piece placement area. The piece placement area is projected onto the base plate 510, and the seat piece 540, adhesive, and fastening strip are all located in the piece placement area. It can be understood that the multiple retaining clips 520 are used to clamp the edge portion of the seat piece 540 to fix the seat piece 540. The multiple retaining clips 520 are arranged together to form a piece placement area, so as to facilitate the operator to place the seat piece 540.

[0042] In one of the embodiments, the adhesive is a self-adhesive.

[0043] In one of the embodiments, the fixing columns 530 are vertically arranged on the bottom plate 510. In this way, when the needle sewing operation is performed, since the clamping buckles 400 buckle the fixing columns 530, when the horizontal driving cylinder and / or the longitudinal moving cylinder drives the horizontal moving rod 310 and / or the longitudinal moving rod 320 to move, the horizontal moving rod 310 and / or the longitudinal moving rod 320 drives the bottom plate 510 to move, at this time, the side wall part of the fixing column 530 is uniformly stressed at any position, which can ensure the stability of the needle sewing and prevent the fixing column 530 from being separated from the buckle slot 400a.

[0044] The present disclosure also provides an automobile seat manufacturing equipment, which comprises the seat cover sewing device 10 of any one of the above embodiments.

[0045] Compared with the prior art, the present disclosure has at least the following advantages:

[0046] The seat cover sewing device 10 described above adopts the clamping buckle 400, the clamping buckle 400 is installed on the horizontal moving rod 310, the seat cover fixing assembly 500 has the fixing column 530, when the installation buckling strip and the seat piece 540 are completed and fixed, the bottom plate 510 is moved so that the plurality of fixing columns 530 are located in the corresponding buckle slot 400a, then the machine is operated so that the buckle driving cylinder 430 drives the moving block 420 to close, so that the clamping buckle 400 buckles the fixing column 530, so that when the machine performs the needle sewing step, the seat piece 540 will not be deviated under the action of the fixing clamp 520, and the bottom plate 510 will not be deviated under the action of the clamping buckle 400. In this way, the seat cover sewing device 10 does not need to move the needle, and does not need manpower, and only needs to move the bottom plate 510 by cooperation of the horizontal moving rod 310 and the longitudinal moving rod 320 under the condition that the clamping buckle 400 buckles the fixing column 530.

[0047] The above-described embodiments only express several implementation manners of the present disclosure, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the disclosed patent. It should be noted that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent should be subject to the appended claims.
