[0024] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0025] In an embodiment of the present invention, as Figures 1 to 6As shown in the figure, an L-shaped circuit board holder is provided, which includes a main frame body 1, a plurality of first row bars 2 and a plurality of second row bars 3. A bottom plate 11 is provided at the bottom of the main frame body 1, and an identification area 12 is provided at the bottom of the bottom plate 11. An L-shaped groove 13 is formed by inward depression on the front side of the main frame body 1. The inner bottom edge of the groove 13 slopes downward into the groove 13, and the inner bottom edge of the groove 13 is perpendicular to the inner side edge of the groove 13. Each of the first row bars 2 is distributed from top to bottom on the inner side edge of the groove 13, and each of the second row bars 3 is distributed from left to right on the inner bottom edge of the groove 13. A plurality of first slots 21 are evenly arranged on the first row bar 2, and a plurality of second slots 31 are evenly arranged on the second row bar 3. Each of the first slots 21 corresponds to each of the second slots 31 one by one. A spring piece 4 is detachably connected to one side wall of each of the first slots 21 and one side wall of each of the second slots 31. The movable ends of each of the spring pieces 4 extend into the first slots 21 and the second slots 31 respectively.

[0026] Further, the identification area 12 includes a two-dimensional code sheet 121 and a front-back identification hole 122. The two-dimensional code sheet 121 is installed in the middle of the bottom plate 11, and the front-back identification hole 122 is provided on one side of the bottom plate 11, and the front-back identification hole 122 penetrates through the bottom plate 11, the main frame body 1, and the groove 13 from bottom to top and opens outward. Specifically, when the main frame body 1 is pushed into the board handling machine by a carrier cart, the two-dimensional code sheet 121 is identified by the identification program in the board handling machine, so as to record or read the board serial number in the main frame body 1. At the same time, the front-back identification hole 122 can be detected by a detection mechanism. When the detection signal sent by the detection mechanism can pass through the front-back identification hole 122 smoothly without being blocked, it means that the position of the main frame body 1 is accurate, ensuring that the orientation of the main frame body 1 is correct when it enters the board handling machine, so that the board handling operation can be carried out smoothly.

[0027] Further, a plurality of positioning holes 14 are symmetrically provided on the front and rear sides of the bottom surface of the bottom plate 11. Specifically, the main frame body 1 can be positioned through the positioning holes 14 with the positioning pins on the carrier cart to ensure the position of the main frame body 1 on the carrier cart is fixed. At the same time, after the main frame body 1 is transported into the board handling machine by the carrier cart, it can accurately reach the corresponding position, so that the robot of the board handling machine can accurately perform the board handling operation. The plurality of positioning holes 14 can be divided into two groups. One group of positioning holes 14 is provided in the middle position of the bottom plate 11, and the other group of positioning holes 14 is provided on the front and rear sides of the bottom plate 11. The positioning pins of the carrier cart are positioned and fixed with the positioning holes 14 provided in the middle of the bottom plate 11. Another positioning pin can also be provided in the board handling machine to position with the other group of positioning holes 14, so that the position of each group of main frame bodies 1 is fixed after entering the board handling machine.

[0028] Further, a first partition strip 211 is provided between each of the first slots 21. The first partition strip 211 has a trapezoidal structure, and the first slot 21 has an inverted trapezoidal structure. The wide side of the first slot 21 opens outward, and the fixed end of the elastic piece 4 is detachably connected to the first partition strip 211. A second partition strip 32 is provided between each of the second slots 31. The second partition strip 32 has a trapezoidal structure, and the second slot 31 has an inverted trapezoidal structure. The wide side of the second slot 31 opens outward, and the fixed end of the elastic piece 4 is detachably connected to the second partition strip 32. Specifically, due to the above structure, the structures of the first slot 21 and the second slot 31 are both gradually shrinking inward from the opening side. When the rear side and the bottom of the plate member are gradually inserted into the first slot 21 and the second slot 31 respectively, the greater the clamping effect of the first slot 21 and the second slot 31 themselves, and at the same time, the greater the elastic clamping effect of the elastic piece 4, ensuring the stability of the plate member within the main frame body 1.

[0029] Further, the second partition strip 32 includes a base 321 and a peak portion 322 provided on the top of the base 321. The steepness of the two sides of the base 321 is greater than that of the two sides of the peak portion 322. A buffer portion 323 is connected between the bottom surface of the peak portion 322 and the top surface of the base 321. The two sides of the buffer portion 323 have a circular arc structure for connecting the sides of the peak portion 322 and the base 321. Specifically, when the bottom of the plate member is inserted into the second slot 31, the bottom of the plate member first passes through the peak portions 322 on both sides of the second slot 31 and elastically squeezes the elastic piece 4. When the bottom of the plate member reaches the position of the buffer portion 323, one side of the bottom of the plate member squeezes the elastic piece 4 towards the circular arc structure of the buffer portion 323, and causes the elastic piece 4 to deform towards the direction close to the base 321 with the circular arc structure as the fulcrum, so that the elastic piece 4 has a stronger elastic clamping effect on the plate member.

[0030] Further, the bottom of the main frame body 1 is a support portion 15 with a hollow structure. The support portion 15 opens towards the rear side of the main frame body 1. A cross beam 151 is provided at the opening of the support portion 15. A support plate 152 and a reinforcing rib 153 are arranged inside the support portion 15. The upper and lower sides of the support plate 152 are respectively fixedly connected to the upper and lower sides inside the support portion 15. One end of the reinforcing rib 153 is fixedly connected to the cross beam 151, and the other end is fixedly connected to the front side wall inside the support portion 15. Specifically, the hollow structure of the support portion 15 can effectively reduce the weight of the main frame body 1, so that it is more labor-saving when the carrier trolley transports the main frame body 1. The structure of the main frame body 1 is strengthened by the support plate 152 and the reinforcing rib 153, improving the firmness of the main frame body 1.

[0031] Working principle: When in use, the main frame 1 is placed on the carrier trolley, and the main frame 1 is transported to the retractable trigger machine by the trolley. The identification area 12 of the bottom plate 11 is used to check whether the main frame 1 is aligned, and the identification program of the retractable trigger machine can identify the serial numbers of all panels loaded in the main frame 1 through the identification area 12; an empty main frame 1 can also be placed into the retractable trigger machine through the trolley, and the identification program in the retractable trigger machine identifies and registers the identification area 12 of the main frame 1, and then the panel is inserted into the main frame 1 through the retractable trigger. In this process, the retractable trigger grabs the panel and inserts the back side of the panel into the first slot 21 first, and clamps the back side of the panel through the spring piece 4 in the first slot 21, and then passes the panel Drag it downward and insert the bottom of the plate into the second slot 31. The bottom of the plate is clamped by the spring piece 4 in the second slot 31. After the plate is installed in the groove 13 of the main frame 1, the plate will lean tightly against the groove 13 due to gravity to prevent the plate from falling out of the main frame 1 during transportation, thereby achieving a better fixing effect. In addition, under the clamping action of the spring piece 4, the plate is prevented from being damaged by bumps. At the same time, the spring piece 4 can adapt to the clamping of plates of different thicknesses; it can also adapt to the use of plates of different sizes. The longer the length of the rear side of the plate, the more the first slot 21 clamped at the rear side of the plate, and the longer the length of the bottom of the plate, the more the second slot 31 clamped at the bottom of the plate. Figure 1 It can be seen from the diagram that there are different sized panels installed on the main frame 1, wherein the rear side of the larger panel is fixed by the first slots 21 of the four first plug-in strips 2, and the bottom is fixed by the second slots 31 of the four second plug-in strips 3; wherein the rear side of the smaller panel is fixed by the first slots 21 of the three first plug-in strips 2, and the bottom is fixed by the second slots 31 of the three second plug-in strips 3, and so on, and the number of first plug-in strips and second plug-in strips to be used is determined according to the different lengths of the rear side and the bottom of the panel, and the scope of use is wider.
