[0027] like Figures 1-5 As shown, the utility model provides a spray line support rod fixing device.

[0028] In an exemplary embodiment, the spray line support rod fixing device includes a support frame 1, a guide rail is provided on the support frame 1, and a plurality of clamping mechanisms 7 are provided on the guide rail. The clamping mechanisms 7 are used to fix the support rod 10. The support frame 1 is provided with a driving mechanism, and the driving mechanism includes a conveyor belt 4. The clamping mechanism 7 is connected to the conveyor belt 4, and the clamping mechanism 7 can move cyclically along the guide rail under the drive of the conveyor belt 4.

[0029] In this embodiment, multiple clamping mechanisms 7 are set up, which can fix the support rod 10 on each conveying device 9 under the drive of the driving mechanism. Before the support rod 10 enters the target point, the support rod 10 is locked to prevent it from rotating. When the robot arm 8 visually locates and places the product subsequently, it can achieve precise correspondence, ensuring the normal production of the product, avoiding product placement failure, and reducing losses in the production process.

[0030] It is worth noting that the cyclically movable clamping mechanism 7 provided in this embodiment can fix each support rod 10 on the conveying device 9 to ensure that the support rod 10 is fixed before entering the target point, thereby achieving precise positioning and accurate placement of the product.

[0031] In an exemplary embodiment, the clamping mechanism 7 includes a connecting portion and a clamping portion, the connecting portion is connected to the conveyor belt 4, and the clamping portion is provided on the connecting portion.

[0032] The clamping jaw mechanism 7 in the embodiment mainly adopts a connecting part and a clamping part. The connecting part is mainly used for being connected with the guide rail to move on the guide rail. The driving force of the connecting part is derived from the conveying belt 4. The conveying belt 4 can drive the whole clamping jaw mechanism 7 to move along the guide rail in the moving process. The clamping part is mainly used for fixing the supporting rod 10.

[0033] For example, the connecting part includes a mounting plate 702 and a fixed plate 701. The bottom of the mounting plate 702 is provided with a plurality of guide wheels 703 matched with the guide rail. The mounting plate 702 is provided with a connecting plate 704 used for being connected with the conveying belt 4. The fixed plate 701 is arranged on the side of the mounting plate 702 away from the guide wheels 703. The clamping part is arranged on the fixed plate 701. The number of the guide wheels 703 in the embodiment is four, which are symmetrically distributed on both sides of the guide rail to provide stable guiding effect. The fixed plate 701 in the embodiment is installed on the upper surface of the mounting plate 702. The clamping part is installed on the fixed plate 701 by means of bolt connection or the like.

[0034] For example, the clamping part includes a fixed seat 705. The fixed seat 705 is symmetrically provided with clamping arms 708. The clamping arms 708 are rotationally connected to the fixed seat 705. The clamping arms 708 are provided with positioning blocks 709. The positioning blocks 709 are provided with clamping blocks 710. The clamping blocks 710 are provided with clamping grooves 711 which can be matched with the supporting rod 10. Figure 2 As shown in the figure, the clamping blocks 710 have loosening positions and clamping positions. The clamping blocks 710 close to the conveying device 9 are clamping positions. The clamping blocks 710 away from the conveying device 9 are loosening positions. When the clamping blocks 710 are in the clamping positions, the clamping grooves 711 of the clamping blocks 710 fix the supporting rod 10. In the embodiment, the clamping arms 708 are rotationally connected to the fixed seat 705. When it is needed to clamp the supporting rod 10, the clamping arms 708 are rotated. The end portions of the clamping arms 708 are close to each other, thereby driving the clamping blocks 710 to be close to each other. Finally, the clamping blocks 710 are rotated by ninety degrees from the horizontal position to the vertical position, thereby realizing the switching from the loosening position to the clamping position. When in the clamping position, there is a certain gap between the two clamping blocks 710. The clamping grooves 711 limit the clamping of the supporting rod 10. When in the clamping position, the inner wall of the clamping grooves 711 is in full contact with the supporting rod 10, thereby increasing the friction between the supporting rod 10 and the clamping grooves 711. Finally, the function of preventing the supporting rod 10 from rotating is realized.

[0035] It is worth noting that in this embodiment, a switching mechanism is provided in the fixed seat 705. The switching mechanism is mainly used to drive the clamping block 710 to switch between the release position and the clamping position. The switching mechanism in this embodiment includes a connecting rod 706 that is slidably connected to the fixed seat 705. The front end of the connecting rod 706 (the end away from the conveyor belt 4) is fixedly connected to a connecting piece 707, and the clamping arm 708 is hinged on the connecting piece 707. When the connecting rod 706 slides backward, the connecting rod 706 drives the connecting piece 707 backward, and the connecting piece 707 drives the end of the clamping arm 708 to move backward. Due to the limiting effect of the fixed seat 705, the surface of the clamping arm 708 is stuck, so that the clamping arm 708 can only rotate around the connecting piece 707, thereby achieving the approach of the clamping blocks 710, and finally achieving the fixation of the support rod 10. The connecting rod 706 is driven pneumatically.

[0036] In an exemplary embodiment, the driving mechanism also includes a driving motor, a driving wheel 2 and a driven wheel 3. The driving motor is arranged on the support frame 1, the driving wheel 2 is arranged at the output end of the driving motor, the driving wheel 2 is arranged on the support frame 1, and the conveyor belt 4 is wound between the driving wheel 2 and the driven wheel 3.

[0037] In this embodiment, the motor drives the driving wheel 2 to rotate, and the driving wheel 2 drives the driven wheel 3 to rotate through the conveyor belt 4. The driving wheel 2 and the driven wheel 3 tension the conveyor belt 4, thereby stably driving the clamping mechanism 7 to move.

[0038] For example, the driving wheel 2 and the driven wheel 3 may also be sprockets. Accordingly, the conveyor belt 4 may be a chain, which cooperates with the sprockets and can also drive the clamping mechanism 7 to move.

[0039] Exemplarily, the conveyor belt 4 has the same shape as the guide rail, and the relative distance between the conveyor belt 4 and the guide rail is equal at all places. In this embodiment, the guide rail and the conveyor belt 4 are both elliptical, so that the clamping mechanism 7 can be driven to clamp the support rod 10 in a circular and reciprocating manner.

[0040] In an exemplary embodiment, the guide rail includes a first rail 5 and a second rail 6 connected end to end. The first rail 5 is a straight rail, and the second rail 6 is a curved rail.

[0041] In this embodiment, the first track 5 and the second track 6 can form the entire guide rail into an elliptical circulating track, so that the clamping mechanism 7 can achieve a reciprocating cycle.

[0042] In an exemplary embodiment, the distance between the clamping jaws 7 is equal to the distance between the supporting rods 10 .

[0043] In this embodiment, the spacing between the clamping mechanisms 7 and the spacing between the support rods 10 are in a corresponding pattern. In this embodiment, the support rods 10 have a dedicated workstation on the conveying equipment 9, and the distances between the support rods 10 are equal. Correspondingly, the distances between the clamping mechanisms 7 are also equal.

[0044] It is worth noting that after the clamping mechanism moves to the designated point along the guide rail, the sensor senses that the support rod 10 enters the target area. At this time, the clamping mechanism 7 is facing the support rod 10, controlling the clamping block 710 to close, clamping the support rod 10, and fixing it.

[0045] It should also be noted that in this embodiment, the transmission speed of the conveyor belt 4 must be kept the same as the conveying speed of the conveying device 9 so as to achieve stable clamping of the support rod 10.

[0046] In an exemplary embodiment, the support frame 1 includes support legs and a support plate, wherein the support plate is disposed on the support legs, and the guide rails are disposed on the support plate.

[0047] In this embodiment, the support legs are used to support the entire device and ensure the stability of the support rod fixing device.

[0048] In summary, the utility model can fix the support rods 10 on the conveying equipment 9 by setting up multiple clamping mechanisms 7, ensuring that each support rod 10 is in a stable fixed state when entering the loading area, thereby achieving effective visual positioning and precise product placement.

[0049] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
