[0027] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail in combination with the drawings.

[0028] The application provides a material bin. Exemplarily, the material bin provided by the application is a circuit board material bin 1, but is not limited thereto, and the application is not limited to the type of the material bin. For example, the material bin of the application can also be a tray material bin or a box material bin.

[0029] Reference Figure 1 The application will be described below by taking the material bin as the circuit board material bin 1 as an example.

[0030] The circuit board material bin 1 of the application comprises a frame 11, a movable part 12, a transmission part 13, a locking mechanism 14, an unlocking mechanism 15 and a lead screw mechanism.

[0031] It can be understood that the number of lead screws of the lead screw mechanism of the application can include one or more. The following is an example of two lead screws, i.e., a first lead screw 16 and a second lead screw 17.

[0032] Specifically, as shown in Figure 1 , the frame 11 has an accommodation space 111, the movable part 12 extends along a first direction (as shown in the X direction in Figure 1 ) and is accommodated in the accommodation space 111, the locking mechanism 14 is arranged on the frame 11, and the unlocking mechanism 15 is arranged opposite to the locking mechanism 14 along a second direction (as shown in the Y direction in Figure 1 ). Exemplarily, the frame 11 of the application further comprises a fixed part 112, the fixed part 112 extends along the first direction X, and the fixed part 112 is arranged opposite to the movable part 12 along the second direction Y, and the locking mechanism 14 is arranged on the side of the fixed part 112 away from the movable part 12.

[0033] Exemplarily, as shown in Figure 1 and Figure 2 , the fixed part 112 and the movable part 12 of the application are both provided with a plurality of sliding grooves 1121 arranged at intervals along the height direction (as shown in the Z direction in Figure 1 ) of the circuit board material bin 1 and a plurality of circuit boards 2. The sliding grooves 1121 extend along the first direction X, and the sliding grooves 1121 on the movable part 12 and the fixed part 112 are arranged one by one to enable the side edges of the circuit boards 2 to be fixed between the movable part 12 and the fixed part 112 in a manner of sliding into the sliding grooves 1121 on the movable part 12 and the fixed part 112 along the first direction X, and stored in the circuit board material bin 1.

[0034] Exemplarily, as shown in Figure 1As shown, the frame 11 of the embodiment of the present application further has an upper wall 1101, a lower wall 1102 and a column 1103 extending along the height direction Z between the upper wall 1101 and the lower wall 1102. The upper wall 1101, the lower wall 1102 and the column 1103 jointly form a containing space 111 and an opening 1104, so that the containing space 111 can communicate with the outside through the opening 1104, and thus the circuit board 2 can pass through the opening 1104 into the containing space 111 along the first direction X and be fixed between the movable element 12 and the fixed element 112.

[0035] The first screw rod 16 and the second screw rod 17 described above both extend along the second direction Y, and the first screw rod 16 and the second screw rod 17 are arranged in the containing space 111 along the first direction X. As shown in the height direction of the circuit board warehouse 1 (for example, the Z direction shown in the figure), the movable element 12 is located above the first screw rod 16 and the second screw rod 17, and the two ends of the movable element 12 are connected to the first screw rod 16 and the second screw rod 17 and are in driving connection with the first screw rod 16 and the second screw rod 17, respectively. Figure 1

[0036] Continuing to refer to Figure 1 , one end 1601 of the first screw rod is provided with a first synchronous pulley 161, and one end 1701 of the second screw rod is provided with a second synchronous pulley 171. As shown in the first direction (for example, the X direction shown in the figure), the transmission element 13 is connected to the first synchronous pulley 161 and the second synchronous pulley 171 to jointly form a synchronous belt transmission system having a main synchronous pulley (for example, the first synchronous pulley 161), a slave synchronous pulley (for example, the second synchronous pulley 171) and a synchronous belt (for example, the transmission element 13). Figure 1

[0037] Exemplarily, the first synchronous pulley 161 of the embodiment of the present application can rotate under the action of an external force (for example, driven by a motor at the device end), and since the first synchronous pulley 161 is in driving connection with the second synchronous pulley 171 through the transmission element 13, the first synchronous pulley 161 drives the transmission element 13 to move along the first direction (for example, the X direction shown in the figure), and the transmission element 13 drives the second synchronous pulley 171 to rotate synchronously. Figure 1

[0038] ​​​And, since the first synchronous pulley 161 is fixedly connected with the first screw rod 16, and the second synchronous pulley 171 is fixedly connected with the second screw rod 17, the first screw rod 16 rotates synchronously with the first synchronous pulley 161, and the second screw rod 17 rotates synchronously with the second synchronous pulley 171. Further, the embodiment of the present application converts the synchronous rotary motion of the first screw rod 16 and the second screw rod 17 into the synchronous linear motion of the two ends of the movable element 12 along the second direction Y, so as to drive the movable element 12 to move along the second direction Y through the transmission connection between the transmission element 13 and the movable element 12, and adjust the width W between the movable element 12 and the fixed element 112, so that the circuit board material bin 1 of the embodiment of the present application can be suitable for storing circuit boards 2 of different sizes.

[0039] Exemplarily, the first screw rod 16 and the second screw rod 17 of the embodiment of the present application are both ball screw rods, and the transmission element 13 is a synchronous belt. However, the embodiment of the present application does not make specific limitation on the form of transmission connection between the movable element 12 and the transmission element 13, as long as the transmission element 13 can drive the movable element 12 to move along the second direction Y. For example, the transmission connection between the movable element 12 and the transmission element 13 can also be in the form of a worm gear.

[0040] It can be understood that, after adjusting the width of the clamping groove, the circuit board material bin in the prior art is susceptible to external force and changes in the width of the clamping groove, which causes the phenomenon of clamping or dropping, affects the use of the circuit board material bin, and reduces the production efficiency.

[0041] However, the circuit board material bin 1 of the embodiment of the present application uses the locking mechanism 14 to limit the movement of the movable element 12 along the second direction (i.e. the depth direction of the circuit board material bin 1), and fixes the width W between the movable element 12 and the fixed element 112, so as to prevent the movable element 12 from moving due to external force and changing the width W between the movable element 12 and the fixed element 112.

[0042] The structure and working principle of the locking mechanism of the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0043] Figure 3 A perspective view of the locking mechanism and the unlocking mechanism provided by the embodiment of the present application is shown, wherein the locking mechanism is in the first state. Figure 4 A perspective view of the locking mechanism and the unlocking mechanism provided by the embodiment of the present application is shown, wherein the locking mechanism is in the second state.

[0044] Reference Figure 3 And Figure 4 The locking mechanism 14 of the embodiment of the present application has a locking portion 141 and a body portion 142.

[0045] Specifically, as Figure 3 And Figure 4As shown, the locking portion 141 is rotationally connected with the body portion 142. Exemplarily, the locking portion 141 has a rotation axis 1411 extending along a first direction (e.g. X direction as shown in Figure 3 and Figure 4 ). The body portion 142 further includes a base 1421 having two through holes 1422 oppositely arranged along the first direction X. Moreover, along the first direction X, the two ends of the rotation axis 1411 respectively pass through the two through holes 1422, and each end of the rotation axis 1411 is rotationally connected with the corresponding through hole 1422.

[0046] Therefore, the locking portion 141 of the embodiment of the present application can rotate relative to the body portion 142 along a third direction (e.g. R direction as shown in Figure 3 and Figure 4 ) in a forward direction or a reverse direction. Further, the locking mechanism 14 of the embodiment of the present application has at least a first state and a second state.

[0047] That is, when the locking mechanism 14 is in the first state, the locking portion 141 is pressed downward by an external force (e.g. elastic force from an elastic member), and the locking portion 141 and the body portion 142 jointly form a locking space 143 (see Figure 4 ) and limit part of the transmission member 13 (see Figure 4 ) in the locking space 143. Therefore, the locking portion 141 can limit the movement of the transmission member 13 relative to the base 1421 of the body portion 142 along the first direction X, so that the width W between the movable member 12 and the fixed member 112 remains unchanged.

[0048] In addition, the locking portion 141 can also rotate relative to the base 1421 of the body portion 142 along the third direction R under the action of an external force (e.g. pushing force from the unlocking mechanism 15) to switch the locking mechanism 14 from the first state to the second state.

[0049] That is, after the locking portion 141 rotates along the third direction R under the action of an external force (e.g. pushing force from the unlocking mechanism 15), the locking mechanism 14 is in the second state. When the locking mechanism 14 is in the second state, the locking portion 141 is spaced apart from the transmission member 13. That is, the transmission member 13 is no longer limited in the locking space 143 formed by the locking portion 141 and the body portion 142. Therefore, the transmission member 13 can move relative to the body portion 142 along the first direction, further driving the movable member 12 to move along a second direction (e.g. Y direction as shown in Figure 3 and Figure 4 ), so that the circuit board material bin 1 of the embodiment of the present application can adjust the width W between the movable member 12 and the fixed member 112.

[0050] Exemplarily, as shown in Figure 3 and Figure 4As shown, the unlocking mechanism 15 of the embodiment of the present application includes an unlocking portion 151 and an unlocking drive portion 152. For example, the unlocking drive portion 152 of the embodiment of the present application is a cylinder, but the embodiment of the present application does not limit the type of the unlocking drive portion 152. For example, the unlocking drive portion 152 can also be a motor.

[0051] Specifically, along the second direction (such as Figure 3 and Figure 4 The unlocking portion 1511 is connected to the unlocking driving portion 152, and the other end 1512 of the unlocking portion is arranged opposite to the locking portion 141. Therefore, when the unlocking driving portion 152 drives the other end 1512 of the unlocking portion to move along the second direction Y toward the locking portion 141, the other end 1512 of the unlocking portion applies an external force (for example, a thrust) to the locking portion 141, so that the locking portion 141 moves along the third direction (for example, Figure 3 and Figure 4 When the unlocking driving portion 152 drives the other end 1512 of the unlocking portion to move along the second direction Y away from the locking portion 141, the other end 1512 of the unlocking portion is separated from the locking portion 141 and no external force is applied to the locking portion 141. The locking portion 141 moves along the third direction (as shown in FIG. Figure 3 and Figure 4 The locking mechanism 14 is switched from the first state to the second state by rotating in the reverse direction (indicated by the R direction).

[0052] Exemplarily, the unlocking mechanism 15 of the embodiment of the present application further includes a fixing seat 153, and the unlocking drive part 152 is installed on the fixing seat 153 to play a fixing role to prevent the unlocking drive part 152 from driving the other end 1512 of the unlocking part to move along the second direction Y and cause deviation.

[0053] Exemplarily, the first direction (i.e., the width direction of the circuit board silo 1) is perpendicular to the second direction (i.e., the depth direction of the circuit board silo 1), and the third direction (i.e., the rotation direction of the locking portion 141 relative to the main body 142) surrounds the first direction.

[0054] Continue to refer Figure 3 and Figure 4 The locking mechanism 14 of the embodiment of the present application further includes an elastic member (not shown in the figure). The elastic member is provided on the main body 142 and has an elastic first end and an elastic second end.

[0055] Exemplarily, the elastic member includes a spring; but not limited to this, the embodiment of the present application does not limit the specific structure of the elastic member, as long as the locking portion 141 and the main body portion 142 can be elastically rotatably connected. For example, the elastic member may also include a torsion spring or an elastic rubber block.

[0056] Specifically, ifFigure 3 and Figure 4 As shown in

[0057] It can be understood that when the locking portion 141 is subjected to an external force (for example, the pushing force of the other end 1512 of the unlocking portion described above), the locking portion 141 is subjected to the pushing force of the other end 1512 of the unlocking portion and rotates in the positive direction of the third direction R, and the locking portion 141 and the body portion 142 press the elastic member, so that the elastic member is in a compressed state (as shown in Figure 3 As shown in

[0058] On the contrary, when the locking portion 141 is not subjected to an external force (for example, the pushing force of the other end 1512 of the unlocking portion described above), the elastic member is elastically opened and is in a reset state (as shown in Figure 4 As shown in

[0059] With reference to Figure 3 and in combination with Figure 4 The locking portion 141 of the present application further comprises a first locking member 1412, and the base 1421 further comprises a second locking member 1423.

[0060] Specifically, the second locking member 1423 extends along the second direction Y. Along the height direction (as shown in ​ and ​The first locking member 1412 and the second locking member 1423 are located on opposite sides of the transmission member 13 in the Z direction. When the locking mechanism 14 is in the first state, the first locking member 1412 and the second locking member 1423 jointly form a locking space 143, and part of the transmission member 13 is limited in the locking space 143 to limit the movement of the transmission member 13 relative to the second locking member 1423 in the first direction X. Exemplarily, the side of the first locking member 1412 facing the transmission member is provided with a plurality of wedge teeth 14121 spaced apart in the first direction X, and the side of the transmission member 13 facing the first locking member 1412 is provided with a plurality of tooth portions 131, the plurality of wedge teeth 14121 are matched with the plurality of tooth portions 131 on the transmission member 13, and the movement of the transmission member 13 relative to the locking mechanism 14 is further limited.

[0061] In summary, the locking mechanism 14 of the embodiment of the present application can automatically lock after adjusting the width between the movable member 12 and the fixed member 112, so as to limit the movement of the transmission member 13 relative to the locking mechanism 14, thereby preventing the movable member 12 from being moved by external force, affecting the width between the movable member 12 and the fixed member 112, and avoiding the occurrence of the phenomena of material jamming or falling.

[0062] Although the present application has been illustrated and described with reference to certain preferred embodiments thereof, it should be understood by those skilled in the art that the above content is a further detailed description of the present application in combination with specific embodiments, and cannot be regarded as a limitation of the specific implementation of the present application. Those skilled in the art can make various changes in form and details, including making a number of simple deductions or substitutions, without departing from the spirit and scope of the present application.
