[0048] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0049] As Figures 1 to 7 shown, a flat tray provided by an embodiment of the present utility model includes a substrate 1 and a plurality of stop bars 2. Multiple layers of material plates can be stacked and placed on the substrate 1, and the plurality of stop bars 2 are installed on the substrate 1 and can limit the material plates.

[0050] The stop bar 2 includes a sleeve 21, a connecting rod 22 and a locking member 23. The sleeve 21 is sleeved outside the connecting rod 22, the connecting rod 22 can slide in the sleeve 21, an accommodating groove 2131 for installing the locking member 23 is provided on the outer peripheral surface of the sleeve 21, and an avoidance groove 24 is provided between the outer surface of one end of the connecting rod 22 close to the substrate 1 and the inner wall surface of the sleeve 21, and the accommodating groove 2131 communicates with the avoidance groove 24.

[0051] A connecting hole 11 is provided on the substrate 1, and a stopping portion 1121 is provided in the connecting hole 11. The connecting rod 22 can move relative to the sleeve 21 along the first direction a and switch between a first position and a second position. When the connecting rod 22 is in the first position, the locking member 23 protrudes from the outer peripheral surface of the sleeve 21 and abuts against the stopping portion 1121 to prevent the stop bar 2 from detaching from the connecting hole 11, thereby locking the stop bar 2 on the substrate 1.

[0052] After the connecting rod 22 is switched from the first position to the second position, the locking member 23 can move from the accommodating groove 2131 to the avoidance groove 24 when the blocking rod 2 moves along the first direction, so that the locking member 23 can avoid the stop portion 1121, releasing the abutment between the locking member 23 and the stop portion 1121, so that the blocking rod 2 can enter or leave the connecting hole 11, thereby realizing the insertion and removal of the blocking rod 2 in the connecting hole 11.

[0053] When the blocking rod 2 is installed on the substrate 1, the connecting rod 22 is manipulated to move from the first position to the second position along the first direction. At this time, the avoidance groove 24 is used to provide a space for the locking member 23 to move. After the blocking rod 2 is inserted into the connecting hole 11, the locking member 23 moves from the receiving groove 2131 to the avoidance groove 24. At this time, the locking member 23 is simultaneously accommodated in the receiving groove 2131 and the avoidance groove 24, so that the locking member 23 does not protrude from the outer surface of the sleeve 21, and the blocking rod 2 is smoothly inserted into the connecting hole 11 of the substrate 1. Then, after the connecting rod 22 returns to the first position, the locking member 23 protrudes from the outer peripheral surface of the sleeve 21, forming an abutment with the stopper 1121, thereby locking the blocking rod 2 and preventing the blocking rod 2 from being pulled out of the connecting hole 11.

[0054] When the blocking rod 2 needs to be disassembled, the connecting rod 22 is operated to move from the first position to the second position. At this time, the avoidance groove 24 is docked with the accommodating groove 2131. When the blocking rod 2 moves in the connecting hole 11 along the first direction, the locking member 23 is affected by the external force and enters the avoidance groove 24. The locking member 23 no longer abuts the stop portion 1121, so that the blocking rod 2 can be smoothly pulled out of the connecting hole 11.

[0055] In this embodiment, the position of the locking member 23 can be changed by switching the connecting rod 22 between the first position and the second position. When the locking member 23 protrudes from the sleeve 21, it is blocked by the stop portion 1121, and the blocking rod 2 cannot be separated from the connecting hole 11, so that the blocking rod 2 is in a locked state. When part of the locking member 23 enters the avoidance groove 24, the blocking rod 2 is no longer blocked by the stop portion 1121 when moving in the connecting hole 11, and is now in an unlocked state. The blocking rod 2 can be pulled out or inserted into the connecting hole 11 without hindrance. During the plugging and pulling out of the blocking rod 2, it is only necessary to move the connecting rod 22 along the first direction to lock or unlock the blocking rod 2, thereby realizing a quick plugging and pulling out process of the blocking rod 2, which can reduce the installation time of the blocking rod 2 and does not require special tools. The installation is more convenient, thereby enhancing work efficiency.

[0056] In one embodiment, the connecting rod 22 includes a rod body 221 and a locking head 222. The locking head 222 is connected to one end of the rod body 221 close to the substrate 1. An avoidance groove 24 is provided between the locking head 222 and the sleeve 21. The rod body 221 moves in the sleeve 21, thereby driving the locking head 222 to move in the first direction, so that the position of the avoidance groove 24 in the first direction can change, which helps to cooperate with the locking member 23 to achieve locking or unlocking.

[0057] When the connecting rod 22 is in the first position, the receiving groove 2131 and the avoidance groove 24 are misaligned in the first direction a. The locking member 23 abuts against the wall surface of the connecting hole 11 and the locking head 222 in the second direction b. The second direction b is not parallel and does not coincide with the first direction a. At this time, the locking member 23 cannot enter the avoidance groove 24. Under the blocking of the locking member 23 and the stop portion 1121, the blocking rod 2 is held in the connecting hole 11 and is in a locked state.

[0058] When the connecting rod 22 is switched from the first position to the second position, one end of the locking head 222 protrudes from the sleeve 21. The avoidance groove 24 approaches the receiving groove 2131 in the first direction. The avoidance groove 24 is aligned with the receiving groove 2131 in the second direction to provide a movable space for the locking member 23. After the locking member 23 moves towards the avoidance groove 24, the locking function of the locking member 23 is released.

[0059] Wherein, after the connecting rod 22 is switched to the second position, when the blocking rod 2 moves in the connecting hole 11, a force is applied to the locking member 23 through the hole wall of the connecting hole 11 and / or the stop portion 1121, which can drive the locking member to move from the receiving groove 2131 into the avoidance groove 24.

[0060] In one embodiment, the second direction b is perpendicular to the first direction a. The first direction a is the vertical direction as shown in Figure 2 and the second direction b is the horizontal direction as shown in Figure 2 . The first position is above the second position. When the connecting rod 22 moves downward relative to the sleeve 21, it can move from the first position to the second position. When the connecting rod 22 moves upward relative to the sleeve 21, it can move from the second position to the first position.

[0061] In one embodiment, the locking head 222 includes a first connecting portion 2221 and a second connecting portion 2222. The first connecting portion 2221 is arranged in the first direction at one end of the second connecting portion 2222 close to the rod body 221. That is, in the first direction, the first connecting portion 2221 is located above the second connecting portion 2222. The avoidance groove 24 is formed between the outer peripheral surface of the first connecting portion 2221 and the inner wall surface of the sleeve 21, so that when the avoidance groove 24 moves up and down with the first connecting portion 2221, the alignment and misalignment of the avoidance groove 24 and the receiving groove 2131 can be realized.

[0062] Wherein, when in the first position, the locking member 23 abuts between the wall surface of the connecting hole 11 and the second connecting portion 2222 in the second direction, and the receiving groove 2131 is located below the avoiding groove 24, and a dislocation can be formed in the first direction. When the connecting rod 22 moves downward to the second position, the end of the second connecting portion 2222 away from the first connecting portion 2221 protrudes from the sleeve 21. At this time, the first connecting portion 2221 moves downward to the receiving groove 2131, so that the avoiding groove 24 is aligned with the receiving groove 2131 in the second direction, thereby realizing the avoidance of the locking member 23 to the stop portion 1121.

[0063] In an embodiment, in the direction away from the first connecting portion 2221, the dimension of the second connecting portion 2222 in the second direction gradually increases, that is, the width of the second connecting portion 2222 in the horizontal direction gradually increases. When the connecting rod 22 moves from the second position to the first position, the second connecting portion 2222 can push the locking member 23 away from the avoiding groove 24, so that the locking member 23 protrudes from the outer peripheral surface of the sleeve 21, thereby realizing the locking of the stop rod 2 in the connecting hole 11.

[0064] In an embodiment, in the first direction, the cross-sectional shape of the second connecting portion 2222 is trapezoidal, and the outer portion of the second connecting portion 2222 has an inclined surface. Through the above inclined surface, the gap between the second connecting portion 2222 and the sleeve 21 gradually decreases downward. In this way, when the connecting rod 22 moves upward to the first position, the locking member 23 leaves the avoiding groove 24 and contacts the above inclined surface, and the inclined surface can push the locking member 23. Under the limitation of the receiving groove 2131, the locking member 23 moves in the second direction, so that the locking member 23 can protrude from the outer surface of the sleeve 21.

[0065] Further, the second connecting portion 2222 is conical, and when the locking member 23 is installed at any position on the outer peripheral surface of the sleeve 21, the second connecting portion 2222 can push the locking member 23.

[0066] In an embodiment, at the junction of the first connecting portion 2221 and the second connecting portion 2222, the dimension of the first connecting portion 2221 in the second direction is the same as the dimension of the second connecting portion 2222 in the second direction, so that the outer surface of the second connecting portion 2222 and the outer surface of the first connecting portion 2221 are smoothly transitioned, and there is no step at the junction of the first connecting portion 2221 and the second connecting portion 2222, and the locking member 23 will not be stuck when leaving the avoiding groove 24.

[0067] In an embodiment, the first connecting portion 2221 is cylindrical, and the dimension of the first connecting portion 2221 in the second direction remains the same from top to bottom.

[0068] In one embodiment, the lock head 222 further includes a limiting portion 2223. The limiting portion 2223 is connected to one end of the second connecting portion 2222 away from the rod body 221. A limiting groove 2132 is provided on the sleeve 21. When the connecting rod 22 moves back and forth in the first direction, the limiting portion 2223 can enter or leave the limiting groove 2132. Among them, when the connecting rod 22 moves from the first position to the second position, one end of the second connecting portion 2222 away from the first connecting portion 2221 protrudes from the sleeve 21, and the limiting portion 2223 can leave the limiting groove 2132. When the connecting rod 22 moves from the second position to the first position, the limiting portion 2223 is fitted in the limiting groove 2132, thereby limiting the relative position of the connecting rod 22 and the sleeve 21.

[0069] In one embodiment, the limiting portion 2223 is annular and is arranged around the outer edge of the second connecting portion 2222. Correspondingly, the limiting groove 2132 is annular, so that the second connecting portion 2222 and the sleeve 21 can perform relative movement in the circumferential direction, which is convenient for the assembly of the limiting portion 2223 and the limiting groove 2132, and can improve the assembly efficiency of the connecting rod 22 on the sleeve 21.

[0070] In one embodiment, the connecting rod 22 further includes an elastic member 25 sleeved outside the rod body 221. The elastic member 25 is arranged inside the sleeve 21. When the connecting rod 22 moves from the first position to the second position, the elastic member 25 is squeezed. The elastic member 25 is used to generate an elastic force for driving the connecting rod 22 to return to its original position, so that the connecting rod 22 can return to the first position to realize the stop between the locking member 23 and the stop portion 1121, and further realize the locking of the shift lever 2.

[0071] During the process of installing the shift lever 2 on the substrate 1, by an operator pressing the connecting rod 22, the connecting rod 22 moves from the first position to the second position. After the connecting rod 22 moves to the second position, the avoidance groove 24 is aligned with the receiving groove 2131 in the second direction. The shift lever 2 is inserted into the connecting hole 11. Under the extrusion of the wall surface of the connecting hole 11 and the stop portion 1121, the locking member 23 is pushed to move from the receiving groove 2131 to the avoidance groove 24. After being inserted in place, the connecting rod 22 is released. Under the elastic force of the elastic member 25, the connecting rod 22 automatically returns to its original position, and the second connecting portion 2222 pushes the locking member 23 to leave the avoidance groove 24 and abut against the stop portion 1121, thereby realizing the locking of the shift lever 2.

[0072] In this embodiment, by manually pressing the connecting rod 22, the insertion and extraction of the shift lever 2 in the connecting hole 11 can be realized. Releasing the connecting rod 22 can lock it, which can achieve the purpose of quickly installing and disassembling the shift lever 2 and save the disassembly and assembly time of the shift lever 2.

[0073] In one embodiment, the elastic member 25 is a spring.

[0074] In one embodiment, a first step 214 is provided inside the sleeve 21, and a second step 2213 is provided on the rod body 221. The elastic member 25 is located between the first step 214 and the second step 2213 in the first direction, thereby defining the position of the elastic member 25. During the movement of the connecting member in the first direction, the elastic member 25 can be compressed or restored to its deformed state.

[0075] In one embodiment, the sleeve 21 includes a first sleeve 211 and a second sleeve 212 connected to each other. The first sleeve 211 is located at the end of the second sleeve 212 away from the substrate 1. The dimension of the first sleeve 211 in the second direction is larger than the dimension of the second sleeve 212 in the second direction, such that the first step 214 is formed at the junction of the first sleeve 211 and the second sleeve 212.

[0076] The rod body 221 includes a first rod body 2211 and a second rod body 2212 connected to each other. The first rod body 2211 is located at the end of the second rod body 2212 away from the lock head 222. The dimension of the first rod body 2211 in the second direction is larger than the dimension of the second rod body 2212 in the second direction, and the second step 2213 is formed at the junction of the first rod body 2211 and the second rod body 2212.

[0077] The first rod body 2211 and the elastic member 25 are arranged inside the first sleeve 211. One end of the second rod body 2212 is arranged inside the first sleeve 211 and connected to the first rod body 2211, and the other end of the second rod body 2212 is arranged inside the second sleeve 212 and connected to the lock head 222.

[0078] Since the dimension of the second rod body 2212 in the second direction is small, a cavity for accommodating the elastic member 25 is formed between one end of the second rod body 2212 and the first sleeve 211. One end of the elastic member 25 abuts against the first step 214, and the other end of the elastic member 25 abuts against the second step 2213, which can limit the elastic member 25. When the connecting rod 22 is pressed to move from the first position to the second position, the rod body 221 moves inside the sleeve 21, and the second step 2213 squeezes the elastic member 25. When the connecting rod 22 is released, the elastic force of the elastic member 25 pushes the second step 2213, causing the connecting rod 22 to return to the first position.

[0079] The sleeve 21 is a tubular structure with openings at both ends. During assembly, first, the elastic member 25 is sleeved on the rod body 221, and the rod body 221 is inserted into the sleeve 21 through one end opening, such that the first rod body 2211 enters the first sleeve 211 and the second rod body 2212 enters the second sleeve 212. Then, the lock head 222 is inserted into the sleeve 21 through the other end opening, and the lock head 222 is installed on the second rod body 2212.

[0080] In one embodiment, the first rod body 2211 and the second rod body 2212 are cylindrical, and the first sleeve 211 and the second sleeve 212 are cylindrical, facilitating the relative axial movement between the connecting rod 22 and the sleeve 21.

[0081] In one embodiment, a snap ring 223 is provided at one end of the connecting rod 22 away from the substrate 1. The snap ring 223 can abut against the sleeve 21 to limit the connecting rod 22 when the connecting rod 22 moves from the first position to the second position, thereby being able to limit the downward movement distance of the connecting rod 22.

[0082] In one embodiment, a plurality of locking members 23 are provided. A plurality of receiving grooves 2131 are provided and arranged around the outer peripheral surface of the sleeve 21. Each locking member 23 is arranged in a corresponding receiving groove 2131. When the connecting rod 22 switches to the second position, the plurality of locking members 23 can move synchronously towards the avoidance groove 24. When the connecting rod 22 switches to the first position, the plurality of locking members 23 abut against the stop portion 1121, further enhancing the locking effect of the shift lever 2.

[0083] In one embodiment, the locking member 23 is a ball, the receiving groove 2131 is circular, and in the second direction, the opening area of the end of the receiving groove 2131 close to the connecting rod 22 is larger than the opening area of the end of the receiving groove 2131 away from the connecting rod 22, such that the ball can only move towards the inside of the drum and cannot move out of the receiving groove 2131 towards the outside of the drum.

[0084] In one embodiment, the substrate 1 has a first surface 12 and a second surface 13 oppositely arranged in the first direction. The connecting hole 11 extends from the first surface 12 to the second surface 13 along the first direction a. In the direction from the first surface 12 to the second surface 13, the size of the stop portion 1121 gradually increases in the second direction, that is, the width of the stop portion 1121 in the horizontal direction gradually increases, such that the gap between the stop portion 1121 and the sleeve 21 gradually decreases from bottom to top, so that the locking member 23 cannot be pulled out from the connecting hole 11.

[0085] When pulling out the shift lever 2 from the connecting hole 11, after the connecting rod 22 moves to the second position and the avoidance groove 24 is aligned with the receiving groove 2131, the avoidance groove 24 provides space for the locking member 23. Since the gap between the stop portion 1121 and the sleeve 21 gradually decreases, the stop portion 1121 can push the locking member 23 to gradually move towards the direction of the avoidance groove 24, thereby releasing the abutment between the stop portion 1121 and the locking member 23.

[0086] In one embodiment, a third step 215 is provided at one end of the sleeve 21 close to the substrate 1. The third step 215 abuts against the first surface 12, and the insertion position of the sleeve 21 in the connecting hole 11 can be defined through the third step 215.

[0087] In one embodiment, the sleeve 21 further includes a third sleeve 213. A receiving groove 2131 is provided on the third sleeve 213. A limiting groove 2132 is provided at one end of the third sleeve 213 away from the second sleeve 212. The second sleeve 212 is connected between the first sleeve 211 and the third sleeve 213. At the junction of the second sleeve 212 and the third sleeve 213, the dimension of the second sleeve 212 in the second direction is different from the dimension of the third sleeve 213 in the second direction, so that a third step 215 is formed at the junction of the second sleeve 212 and the third sleeve 213, and the installation position of the stop lever 2 is defined when the stop lever 2 is installed on the substrate 1.

[0088] In one embodiment, the connection hole 11 includes a first hole 111, a second hole 112 and a third hole 113. The first hole 111, the second hole 112 and the third hole 113 communicate with each other. The first hole 111 is closer to the first surface 12 than the second hole 112. The third hole 113 is provided at one end of the second hole 112 away from the first hole 111. In the direction from the first surface 12 to the second surface 13, the dimension of the second hole 112 in the second direction gradually increases. The stop portion 1121 is the hole wall surface of the second hole 112, so that the dimension of the stop portion 1121 in the second direction gradually increases, and the locking member 23 can be stopped.

[0089] In the direction from the first surface 12 to the second surface 13, the dimension of the first hole 111 in the second direction remains the same and is the same as the dimension of the second hole 112 at the end close to the first hole 111 in the second direction. The dimension of the third hole 113 in the second direction remains the same and is the same as the dimension of the second hole 112 at the end away from the first hole 111 in the second direction. Since the dimension of the second hole 112 in the second direction gradually increases, the dimension of the first hole 111 in the second direction is smaller than the dimension of the third hole 113 in the second direction.

[0090] In the initial state, the locking member 23 protrudes from the outer peripheral surface of the sleeve 21. After pressing the connecting rod 22 and moving it to the second position, the third sleeve 213 is gradually inserted into the connection hole 11. The inner wall of the first hole 111 can squeeze the locking member 23 to move into the avoidance groove 24, so that the stop lever 2 can be inserted into the connection hole 11 or pulled out from the connection hole 11. When the stop lever 2 is inserted into the connection hole 11, after releasing the pressing on the connecting rod 22, the second connecting portion 2222 squeezes the locking member 23 to protrude from the receiving groove 2131 and abut against the hole wall surface of the second hole 112 to achieve locking.

[0091] In this embodiment, by providing the third hole 113, when the lock head 222 protrudes from the sleeve 21, a receiving space for the lock head 222 can be provided.

[0092] In one embodiment, the cross-sectional shape of the first hole 111 in the second direction is circular, the cross-sectional shape of the second hole 112 in the second direction is circular, and the cross-sectional shape of the third hole 113 in the second direction is circular.

[0093] On the other hand, an embodiment of the present invention provides a PCB processing device, including a machine table, a manipulator, a processing main body, and the flat carrier of the above embodiment. The substrate 1 is used to carry the material plate. The manipulator is used to clamp the material plate and drive the material plate to be transferred between the flat carrier and the machine table. The processing main body is used to process the material plate. The PCB processing device is a drilling machine or a routing machine.

[0094] In one embodiment, the PCB processing device is a laser drilling machine. The processing main body includes a high-speed galvanometer. After the laser beam reaches the galvanometer, the galvanometer emits an accurate laser beam to process holes in the material plate.

[0095] Among them, there are two flat carriers. An unprocessed material plate is placed on one flat carrier, and a processed material plate is placed on the other flat carrier. The manipulator can transfer the unprocessed material plate on one flat carrier to the laser drilling machine for laser processing. After processing, it is grabbed and transferred to the other flat carrier by the manipulator.

[0096] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
