DETAILED DESCRIPTION

[0034] The following will be combined with the accompanying Figures 1-4 Further detailed description of the present application.

[0035] Embodiment 1

[0036] The circuit board transport device disclosed by the embodiment of the present application refers to Figure 1 and Figure 2 The circuit board transport device includes a transport frame 1, the transport frame 1 includes two side frames 14, and the cross bar 11 and the support rod 12 can be provided with one or more than one, and the embodiment takes two cross bars 11 and two support rods 12 as an example. Two cross bars 11 are parallel, two support rods 12 are parallel, and the cross bar 11 is located directly above the support rod 12, and the end of the cross bar 11 and the support rod 12 is detachably connected with the side frame 14 through bolts to form the main structure of the transport frame 1. The bottom of the side frame 14 is also threadedly connected with a pulley, and the specific pulley can be a universal wheel with or without brake, which facilitates the movement of the transport device.

[0037] Referring to Figure 1 and Figure 2 A plurality of fixed plates 2 are further arranged between the cross bar 11 and the support rod 12, the fixed plate 2 is vertically arranged and can move along the length direction of the cross bar 11 and is locked by the locking piece 3. A plurality of clamping grooves 21 are formed on the side wall of the fixed plate 2, the clamping groove 21 penetrates the fixed plate 2 along the horizontal direction, and the plurality of clamping grooves 21 are arranged at equal intervals along the vertical direction. When the circuit board needs to be transported, one end of the circuit board can be inserted into the clamping groove 21, the distance between the adjacent fixed plates 2 is adjusted, and then the fixed plates 2 are locked; or the distance between the fixed plates 2 can also be adjusted and the fixed plates 2 are locked, and then the end of the circuit board is inserted into the end of the clamping groove 21.

[0038] Further, the clamping grooves 21 are formed on the two opposite side walls of the fixed plate 2, and the clamping grooves 21 on the opposite surfaces of the adjacent fixed plates 2 correspond to each other and are equal in height, so that the two ends of the circuit board can enter one clamping groove 21 respectively, and the adjacent two fixed plates 2 provide support for the circuit board at the same time. The circuit board can also be installed on the fixed plate 2 and then the fixed plate 2 is locked, or the circuit board is sequentially slid into the clamping groove 21 from the end of the clamping groove 21 after the position of the fixed plate 2 is adjusted, to realize the installation of the circuit board on the transport device.

[0039] With reference to Figure 1 and Figure 3 A plurality of sliding grooves 23 are formed on the bottom of the fixing plate 2, and the number of the sliding grooves 23 is consistent with the number of the supporting rods 12. In this embodiment, the number of the sliding grooves 23 is two. The supporting rods 12 are one-to-one correspondingly accommodated in the sliding grooves 23. When the fixing plate 2 moves, the supporting rods 12 are always located in the sliding grooves 23, so that the fixing plate 2 can be limited from being separated from the transport frame 1, and the guiding effect is achieved.

[0040] With reference to Figure 2 The locking member 3 comprises a mounting portion 31 and a clamping portion 32. The mounting portion 31 is detachably connected to the top of the fixing plate 2 by a bolt. The clamping portion 32 is rotatably connected to the end of the mounting portion 31 away from the fixing plate 2. Specifically, the bolt can be used as a rotating shaft by penetrating the mounting portion 31 and the clamping portion 32, and the rotating damping force can be provided by the friction force generated by the nut pressing or the damping ring sleeved outside the rotating shaft. In this way, the clamping portion 32 is not easy to rotate. When the clamping portion 32 is rotated, the mounting portion 31 and the clamping portion 32 are wrapped around the lateral side of the cross rod 11, and the clamping portion 32 can abut against the cross rod 11 at this time, so as to limit the movement of the fixing plate 2.

[0041] Further, in this application, the cross rod 11 is a round rod. In order to increase the contact area between the clamping portion 32 and the cross rod 11, the clamping portion 32 comprises a main body portion rotatably connected with the mounting portion 31, and an abutting portion fixed to one end of the main body portion. The end of the abutting portion away from the main body portion is also fixedly connected with the mounting portion 31 by a bolt. The abutting portion comprises an arc-shaped portion 332 capable of abutting against the outer wall of the cross rod 11, and a deformation portion 331 close to one end of the mounting portion 31. The deformation portion 331 has a deformation allowance, which can be a deformable metal portion, so as to improve the damping force between the mounting portion 31 and the clamping portion 32. By arranging the arc-shaped portion 332, the friction force between the clamping portion 32 and the cross rod 11 can be increased, and the position of the fixing plate 2 can be further stabilized. A plurality of indication marks 22 are adhered to the side wall of the fixing plate 2 in the vertical direction. The indication marks 22 are one-to-one used for indicating the positions of the indication slots 21, and are sequentially marked with numbers from top to bottom (not shown in the figure), so as to quickly show the number of the transported circuit boards. The indication marks 22 in the same column are divided into two colors and are arranged at intervals in the vertical direction, so as to facilitate the differentiation between adjacent indication marks 22.

[0042] The implementation principle of the circuit board conveying device is as follows: when the circuit boards of the same specification need to be transferred, one circuit board is first inserted into the clamping groove 21 of the fixed plate 2, and the adjacent fixed plate 2 is moved to provide support for the two fixed plates 2, at this time, the two fixed plates 2 can be locked in position by the locking piece 3, and other circuit boards can be inserted between the two clamping grooves 21 of the fixed plate 2 and installed on the conveying frame 1 for conveying; the circuit boards of other specifications or multiple circuit boards of the same specification can also be conveyed by using the conveying frame 1 in the above manner.

[0043] Embodiment 2

[0044] The difference between the embodiment of the application and embodiment 1 is that:

[0045] Referring to Figure 4 , two side plates 13 are used to replace the two side frames 14, and the cross rod 11 and the support rod 12 are detachably connected to one side plate 13 at one end and detachably connected to the other side plate 13 at the other end. A plurality of clamping grooves 21 are formed on the surfaces of the two side plates 13 facing each other, and the clamping grooves 21 penetrate the side plates 13 in the horizontal direction, and the clamping grooves 21 between the side plates 13 and the adjacent fixed plates 2 are aligned one by one. In the above manner, the space between the side plates 13 and the fixed plates 2 can also be used to install circuit boards, thereby increasing the conveying capacity of the conveying frame 1.
