DETAILED DESCRIPTION

[0023] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0025] In the description of this utility model, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0026] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0027] It is understandable that, referring to Figures 1 to 4 The PCB board transfer cart of the present invention includes a support frame 100, a support base 200 and a limit assembly 300. Rollers are provided at the four corners of the bottom of the support frame 100; the support base 200 is fixedly arranged at the upper end of the support frame 100, and the support base 200 is rotatably connected to a plurality of rollers 210. The plurality of rollers 210 are arranged horizontally and parallel to each other, and the plurality of rollers 210 are evenly spaced along the front and rear directions of the support base 200. The rollers 210 are used to support the PCB board, and a rear stopper 220 is provided at the rear end of the support base 200; the limit assembly 300 includes a fixed base 310 and a limit rod 320. The fixed base 310 is fixedly arranged at the front end of the support base 200, and the limit rod 320 is rotatably connected to the fixed base 310. The limit rod 320 and the rear stopper 220 can respectively abut the front and rear sides of the PCB to position the PCB board.

[0028] When placing the board, since the support base 200 is connected to multiple rollers 210 for rotation, the multiple rollers 210 are arranged horizontally and parallel to each other, and the multiple rollers 210 are evenly spaced along the front and rear directions of the support base 200, so that the PCB board can slide from front to back onto the supporting plane formed by the rollers 210 until the PCB board abuts the rear stopper 220. When the PCB board moves, it can drive the rollers 210 to rotate, thereby reducing the friction resistance between the PCB board and the rollers 210, so as to reduce the possibility of friction damage to the PCB board and facilitate the placement of the PCB board. Then, by rotating the limit rod 320, the limit rod 320 and the rear stopper 220 respectively abut the front and rear sides of the PCB to position the PCB board, thereby reducing the shaking and deviation of the PCB board and reducing the possibility of the PCB board sliding off the support base 200, so as to improve the transportation stability of the PCB board. During transportation, by pushing the support frame 100, the rollers rotate, thereby driving the PCB board on the support base 200 to move, so as to facilitate the transportation of the PCB board.

[0029] It is understandable that, referring to Figures 1 to 3 The limiting components 300 are provided in two groups, and the two groups of limiting components 300 are symmetrically arranged on the left and right sides of the support base 200. Since the two groups of limiting components 300 are symmetrically arranged on the left and right sides of the support base 200, the limiting rods 320 on the left and right sides of the support base 200 simultaneously abut and limit the PCB board, so that the left and right sides of the PCB board are subjected to balanced force, which can improve the positioning stability of the PCB board and further reduce the possibility of the PCB board slipping off the support base 200.

[0030] It is understandable that, referring to Figures 1 to 4 A buffer block 221 is provided on the side of the rear stopper 220 near the limiting rod 320. The buffer block 221 can abut against the PCB. By providing the buffer block 221 on the side of the rear stopper 220 near the limiting rod 320, when placing the PCB, the buffer block 221 abuts against the PCB to cushion the impact of the collision between the PCB and the limiting rod 320. This reduces the possibility of damage to the PCB from colliding with the limiting rod 320, thereby improving the transportation quality of the PCB.

[0031] It should be noted that the buffer block 221 can be an elastic part such as rubber or plastic, which can produce elastic deformation to play a collision buffering role.

[0032] Specifically, refer to Figures 1 to 3 The buffer blocks 221 are provided in a plurality and are evenly spaced along the axial direction of the rear stopper 220. Since the buffer blocks 221 are evenly spaced along the axial direction of the rear stopper 220, the buffer blocks 221 simultaneously abut the PCB board to distribute the force, which can further reduce the possibility of the PCB board being damaged by collision with the limiting rod 320, thereby improving the transportation quality of the PCB board.

[0033] It is understandable that, referring to Figure 1 and Figure 2 A guide assembly 400 is provided at the upper end of the support base 200. The guide assembly 400 includes two guide wheels 410, which are rotatably connected to the support base 200. The two guide wheels 410 are symmetrically arranged on the left and right sides of the support base 200, allowing the PCB to pass between the two guide wheels 410. When the PCB board is slid from the front to the back onto the support plane formed by the rollers 210, the PCB board passes between the guide wheels 410 on the left and right sides of the support base 200. The guide wheels 410 guide and limit the PCB board, allowing the PCB board to slide smoothly onto the support plane and reduce the possibility of the PCB board shaking left and right, thereby improving the transportation quality of the PCB board.

[0034] It should be noted that the guide wheel 410 is axially arranged vertically so that the PCB board moves back and forth to drive the guide wheel 410 to rotate, thereby reducing the friction resistance between the PCB board and the guide wheel 410, thereby reducing the possibility of friction damage to the PCB board.

[0035] Specifically, refer to Figure 1 and Figure 2 The guide assemblies 400 are provided in multiple groups, and the multiple groups of guide assemblies 400 are evenly spaced along the front-to-back direction of the support base 200. Since the multiple groups of guide assemblies 400 are evenly spaced along the front-to-back direction of the support base 200, the multiple groups of guide assemblies 400 can guide and limit the position of the PCB board, which can further improve the position stability of the PCB board, reduce the possibility of the PCB board shaking from side to side, and thus improve the transportation quality of the PCB board.

[0036] It is understandable that, referring to Figure 1 The rear end of the support frame 100 is provided with a handle 110. The handle 110 facilitates the user to apply force to push the support frame 100, thereby improving the convenience of use of the PCB board transfer cart.

[0037] It is understandable that, referring to Figure 1 and Figure 4The support frame 100 is a rectangular frame, which is composed of multiple horizontal support rods 120 and multiple vertical support rods 130. The horizontal support rods 120 on the left and right sides of the bottom of the support frame 100 extend backward from the position of the vertical support rod 130 connected to the rear end to form an extension part 121. The end of the extension part 121 is connected with a reinforcing rib 140, and the reinforcing rib 140 is arranged obliquely in the direction close to the vertical support rod 130. The end of the reinforcing rib 140 away from the extension part 121 is connected to the vertical support rod 130. Since the end of the extension part 121 is connected to the reinforcing rib 140, the reinforcing rib 140 is arranged obliquely toward the direction close to the vertical support rod 130, and the end of the reinforcing rib 140 away from the extension part 121 is connected to the vertical support rod 130, so that a triangular stable structure is formed between the extension part 121, the reinforcing rib 140 and the vertical support rod 130, which can reduce the possibility of the PCB board transfer cart flipping backward when it stops suddenly, thereby reducing the possibility of the PCB board falling and being damaged due to the sudden stop and flipping of the PCB board transfer cart, thereby improving the transportation stability of the PCB board.

[0038] Specifically, refer to Figure 1 and Figure 4 The rollers at the rear end of the support frame 100 are arranged on the extension portion 121. By arranging the rollers at the rear end of the support frame 100 on the extension portion 121, the distance between the front and rear rollers can be increased to improve the support stability, thereby further reducing the possibility of the PCB board transfer cart flipping backward when it stops suddenly.

[0039] It is understandable that, referring to Figure 1 and Figure 4 The two rollers at the front end of the support frame 100 are both configured as fixed rollers 150, and the two rollers at the rear end of the support frame 100 are both configured as universal rollers 160. The universal rollers 160 are provided with brakes 161, which are used to lock the universal rollers 160. The universal rollers 160 facilitate the movement and reversal of the PCB board transfer cart, thereby improving its ease of use. When the PCB board transfer cart moves to a preset position, the brakes 161 lock the universal rollers 160 to position the PCB board transfer cart, thereby facilitating the loading and unloading of PCB boards.

[0040] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
