Description

Technical Field

[0001] The utility model relates to the field of machinery, and particularly relates to an automatic product fixing mechanism. Background Art

[0002] When a PCB (Printed Circuit Board) is spray-painted, it needs to be positioned and fixed to facilitate spray-painting. To improve the spray-painting production capacity, multiple PCBs are usually centrally placed in a customized fixture before spray-painting. Since double-sided spray-painting is required, the PCBs placed in the fixture need to be reliably fixed in the fixture to prevent the PCBs from falling or shifting when the fixture is flipped.

[0003] The current solution for fixing PCBs is to set independent manually rotatable blocks around each independent PCB. After the PCBs are placed in the fixture, the positions of the rotatable blocks are adjusted one by one manually to ensure that the rotatable blocks can reliably hold the PCBs. After the spray-painting is completed, the locks are released one by one manually. Thus, when the number of PCBs to be processed is large, manually unlocking and fixing the fixture one by one requires a large amount of time and labor costs. At the same time, manual fixing increases the risk of the rotatable blocks hitting the PCBs, resulting in damage to the PCBs; there may also be cases of incorrect fixing or missed fixing, increasing the risk of the PCBs falling when flipped; and manual operation has uncertainty, and it is difficult to unify the operation methods, which also increases the risk of the rotatable blocks failing to rotate. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems that manual fixing is time-consuming, labor-intensive, and the operation is cumbersome, and the non-standard actions lead to low product quality. The utility model provides an automatic product fixing mechanism, which can automatically unlock and lock, improve efficiency, save labor costs, and improve product quality.

[0005] To solve the above technical problems, an embodiment of the utility model discloses an automatic product fixing mechanism, including:

[0006] A fixture, which is provided with a placement groove for placing a product;

[0007] A rotating mechanism, which is arranged at the outer edge of the placement groove. The rotating mechanism includes a limiting block and a rotatable block, and the rotatable block is rotatably connected to the limiting block in a manner that it can rotate a first angle;

[0008] A state switching mechanism, which is used to drive the rotatable block to rotate the first angle in a forward or reverse direction along a first direction, so as to drive the rotatable block to switch between a locked state and an unlocked state;

[0009] In the locked state, the rotatable block presses the product along the first direction.

[0010] In the unlocked state, the rotating block does not contact the product.

[0011] For the convenience of description, the implementation mode of the present application is described by taking the product being a PCB as an example, and taking the automatic product fixing mechanism being arranged on a PCB painting production line as an example, but it is not limited to this and may also be other production lines.

[0012] By adopting the above technical solution, when the PCB needs to be painted, the PCB needs to be placed in the placement groove of the fixture first. Since the rotating block is rotatably connected to the limit block in a manner that it can rotate by a first angle, the state switching mechanism can be used to drive the rotating block to rotate in the opposite direction around the first direction by a first angle, so that the rotating block is converted from an unlocked state to a locked state. At this time, the rotating block presses the PCB along the first direction, thereby fixing the PCB. There is no need to manually rotate the rotating block to rotate the rotating block to fix the PCB, thereby saving time and labor costs. At the same time, the machine operation is more standardized, and the uncertainty caused by manual operation can be avoided, so that the fixing effect is better, and the subsequent painting work is not affected, thereby ensuring the painting quality and product quality.

[0013] Similarly, after the PCB is painted, it is necessary to take the PCB out of the placement slot. At this time, the state switching mechanism can be used to drive the rotating block to rotate positively around the first direction by a first angle, so that the rotating block is converted from a locked state to an unlocked state. At this time, the rotating block does not contact the PCB, and the PCB is not fixed. There is no need to manually rotate the rotating block so that the rotating block rotates away and does not contact the PCB, saving time and labor costs. At the same time, the machine operation is more standardized and the uncertainty caused by manual operation can be avoided.

[0014] In summary, the automatic product fixing mechanism provided in the embodiment of the present application can automatically unlock and lock, which greatly improves efficiency, saves labor costs and improves product quality.

[0015] According to another specific embodiment of the utility model, the embodiment of the utility model discloses an automatic product fixing mechanism, the state switching mechanism includes an automatic unlocking mechanism, the automatic unlocking mechanism includes a first toggle member and a first driving part, the first driving part is used to drive the first toggle member to move along the second direction to contact the rotating block, and drive the rotating block to rotate positively around the first direction to the first angle, thereby driving the rotating block to be converted from the locked state to the unlocked state, and a part of the limit block extends along the second direction;

[0016] In the locked state, the rotating block extends along the third direction and forms the first angle relative to a portion of the limiting block, and the rotating block presses the product along the first direction;

[0017] In the unlocked state, the rotating block extends along the second direction and is located above a portion of the limiting block along the first direction, the rotating block does not contact the product, and the second direction and the third direction intersect with the first direction respectively.

[0018] By adopting the above technical solution, after the PCB is painted, it is necessary to take the PCB out of the placement slot. At this time, the rotating block is converted from a locked state to an unlocked state through the automatic unlocking mechanism, that is, the rotating block is converted from pressing the PCB along the first direction to not contacting the PCB.

[0019] Specifically, the first driving unit drives the first toggle member to move in the second direction so that the first toggle member contacts the rotating block. As the first toggle member continues to move in the second direction, the rotating block also continues to rotate forwardly around the first direction until it rotates forwardly around the first direction by a first angle so that the rotating block is converted from a locked state to an unlocked state. At this time, the rotating block does not contact the PCB, and the PCB is not fixed. There is no need to manually rotate the rotating block so that the rotating block rotates away and does not contact the PCB, thereby saving time and labor costs. At the same time, the machine operation is more standardized and the uncertainty caused by manual operation can be avoided.

[0020] According to another specific embodiment of the utility model, the embodiment of the utility model discloses an automatic product fixing mechanism, wherein the first driving part includes a first driving member and a first connecting member, wherein the first connecting member is connected to the first toggle member along the first direction, and wherein the first driving member is connected to the first connecting member along the second direction, and the first driving member is used to drive the first connecting member to move along the second direction to drive the first toggle member to move along the second direction.

[0021] With the above technical solution, after the PCB is painted, it is necessary to take the PCB out of the placement slot. Since the first driving member is connected to the first connecting member, and the first connecting member is connected to the first toggle member, the first driving member can drive the first connecting member to move in the second direction, thereby driving the first toggle member to move in the second direction, so that the first toggle member contacts the rotating block, and as the first toggle member continues to move in the second direction, the rotating block also continuously rotates forward around the first direction until it rotates forward around the first direction by a first angle, so that the rotating block is converted from a locked state to an unlocked state.

[0022] At this time, the rotating block does not contact the PCB, and the PCB is not fixed. There is no need to manually rotate the rotating block so that the rotating block can be rotated away and not contact the PCB, saving time and labor costs. At the same time, the machine operation is more standardized and the uncertainty caused by manual operation can be avoided.

[0023] According to another specific embodiment of the utility model, the embodiment of the utility model discloses an automatic product fixing mechanism, which also includes a third driving mechanism, and the third driving mechanism is used to drive the first toggle member to move along the first direction so that the first toggle member contacts the rotating block or does not contact the rotating block along the first direction.

[0024] By adopting the above technical solution, when the above unlocking work is completed, the third driving mechanism drives the first toggle member to move upward along the first direction (that is, move away from the PCB), so that the first toggle member moves along the first direction until it does not contact the rotating block. At this time, there is no interference from the first toggle member, and the fixture can drive the PCB to continue to move to the next production line or it is convenient to take the PCB out of the placement slot of the fixture at this time, and then carry out the painting work of the next batch of PCBs.

[0025] When the above-mentioned unlocking work is required, the third driving mechanism drives the first toggle member to move downward along the first direction (that is, move in the direction close to the PCB), so that the first toggle member moves along the first direction until it contacts the rotating block, so that the first toggle member can drive the rotating block to rotate positively around the first direction by a first angle, that is, the above-mentioned unlocking work can be performed.

[0027] By adopting the above technical solution, when the above unlocking work is completed, since the third driving member is connected to the third connecting member, and the third connecting member is connected to the first connecting member, the third driving member can drive the third connecting member to move upward along the first direction at this time, so as to drive the first connecting member to move upward along the first direction, thereby driving the first toggle member to move upward along the first direction (that is, move in the direction away from the PCB), so that the first toggle member moves along the first direction until it does not contact the rotating block. At this time, there is no interference from the first toggle member, and the fixture can drive the PCB to continue to move to the next production line or it is convenient to take the PCB out of the placement slot of the fixture at this time, and then carry out the painting work of the next batch of PCBs.

[0028] When the above-mentioned unlocking work is required, the third driving member can drive the third connecting member to move downward along the first direction, so as to drive the first connecting member to move downward along the first direction, thereby driving the first toggle member to move downward along the first direction (that is, move in the direction close to the PCB), so that the first toggle member moves along the first direction until it contacts the rotating block, so that the first toggle member can drive the rotating block to rotate positively around the first direction to the first angle, that is, the above-mentioned unlocking work can be performed.

[0029] At the same time, since the first connecting member is connected to the third connecting member in a slidable manner along the second direction, that is, when the first driving member drives the first connecting member to move along the second direction, the first connecting member can move relative to the third connecting member along the second direction.

[0033] In the locked state, the rotating block extends along the third direction and forms the first angle relative to a portion of the limiting block, and the rotating block presses the product along the first direction;

[0034] In the unlocked state, the rotating block extends along the second direction and is located above a portion of the limit block along the first direction, the rotating block does not contact the product, the second direction and the third direction intersect with the first direction respectively, and the fourth direction is perpendicular to the second direction.

[0035] By adopting the above technical solution, when the PCB needs to be painted, the PCB needs to be placed in the placement slot, and then the rotating block is converted from an unlocked state to a locked state through the automatic locking mechanism, that is, the rotating block is converted from not contacting the PCB to pressing the PCB along the first direction.

[0036] Specifically, the second driving unit drives the second toggle member to move in the fourth direction so that the second toggle member contacts the rotating block. As the second toggle member continues to move in the fourth direction, the rotating block also continues to rotate in the opposite direction around the first direction until it rotates in the opposite direction around the first direction by a first angle so that the rotating block is converted from an unlocked state to a locked state. At this time, the rotating block presses the PCB in the first direction to fix the PCB. There is no need to manually rotate the rotating block to rotate the rotating block to fix the PCB, which saves time and labor costs. At the same time, the machine operation is more standardized, which can avoid the uncertainty caused by manual operation, so that the fixing effect is better.

[0038] With the above technical solution, when the PCB needs to be painted, the PCB needs to be placed in the placement groove. Since the second driving member is connected to the second connecting member, and the second connecting member is connected to the second toggle member, the second driving member can drive the second connecting member to move along the fourth direction, thereby driving the second toggle member to move along the fourth direction, so that the second toggle member contacts the rotating block, and as the second toggle member continues to move along the fourth direction, the rotating block also continuously rotates in the opposite direction around the first direction until it rotates in the opposite direction around the first direction by a first angle, so that the rotating block is converted from an unlocked state to a locked state.

[0039] At this time, the rotating block presses the PCB along the first direction, thereby fixing the PCB. There is no need to manually rotate the rotating block to fix the PCB, which saves time and labor costs. At the same time, the machine operation is more standardized, which can avoid the uncertainty caused by manual operation, so that the fixing effect is better.

At this time, there is no interference from the second toggle member, and the clamp can drive the PCB to continue to move to the next production line, such as for painting.

[0042] When the above-mentioned locking work is required, the fourth driving mechanism drives the second toggle member to move downward along the first direction (that is, move in the direction close to the PCB), so that the second toggle member moves along the first direction until it contacts the rotating block, so that the second toggle member can drive the rotating block to rotate in the opposite direction around the first direction by a first angle, that is, the above-mentioned locking work can be performed.

At this time, there is no interference from the second toggle member, and the clamp can drive the PCB to continue to move to the next production line, such as for painting.

[0084] Exemplarily, refer to Figure 4 and Figure 7 , the state switching mechanism is used to drive the rotating block 202 to rotate a first angle in the positive direction (i.e., Figure 4 the X direction shown) or the negative direction (i.e., Figure 4 the g direction shown) of the first direction, thereby driving the rotating block 202 to switch between the locked state and the unlocked state; wherein, in the locked state, the rotating block 202 presses the PCB 300 along the first direction (such as Figure 4 the state shown); in the unlocked state, the rotating block 202 does not contact the PCB 300 (refer to Figure 4 the state shown) and Figure 7 ).

[0085] Specifically, refer to Figures 1 to 4 and in combination with Figure 7, the automatic unlocking mechanism 400 described below drives the rotating block 202 to rotate forward by a first angle around the first direction (i.e., the Figure 2 X direction shown), so that the rotating block 202 is converted from the locked state to the unlocked state, that is, from the state shown in Figure 4 to the state shown in Figure 7 .

[0086] It should be noted that the specific value of the first angle is not limited in the embodiment of the present application, and it is specifically selected according to the structure of the PCB 300, as long as the rotating block 202 can press the PCB 300 in the first direction and fix the PCB in the locked state without bumping into the small parts on the PCB 300. For example, it can be 30°, 35°, 40°, 45°, etc.

[0087] Adopting the above technical solution, when the PCB 300 needs to be painted, the PCB 300 needs to be placed in the placement groove 101 of the fixture 100 first. Since the rotating block 202 is rotatably connected to the limiting block 201 in a manner that can rotate by a first angle, the state switching mechanism can drive the rotating block 202 to rotate in the reverse direction of the first direction (i.e., the Figure 4 f direction shown) by a first angle (that is, the angle between the rotating block 202 and the limiting block 201 rotates from 0° to the first angle), so that the rotating block 202 is converted from the unlocked state to the locked state. At this time, the rotating block 202 presses the PCB 300 in the first direction, thus fixing the PCB 300, and there is no need for manual rotation of the rotating block 202 to fix the PCB 300, saving time and labor costs. At the same time, the machine operation is more standard, and the non-uniformity and uncertainty brought by manual operation can be avoided, so that the fixing effect is better and the subsequent painting work is not affected, ensuring the painting quality and the quality of the PCB 300.

[0088] Similarly, when the painting of the PCB 300 is completed, the PCB 300 needs to be taken out of the placement groove 101. At this time, the state switching mechanism can drive the rotating block 202 to rotate forward by a first angle around the first direction (i.e., the Figure 4 g direction shown) (that is, the angle between the rotating block 202 and the limiting block 201 rotates from the first angle to 0°), so that the rotating block 202 is converted from the locked state to the unlocked state. At this time, the rotating block 202 does not contact the PCB 300, so the PCB 300 is not fixed, and there is no need for manual rotation of the rotating block 202 to make the rotating block 202 rotate away from the PCB 300, saving time and labor costs. At the same time, the machine operation is more standard, and the uncertainty brought by manual operation can be avoided.

[0089] Exemplarily, refer to Figure 4 and Figure 5, the limiting block 201 includes a limiting block body 2010, and the limiting block body 2010 extends along the second direction (i.e., Figure 4 the Y direction shown), along the first direction and away from the limiting block body 2010 (i.e., Figure 4 the b direction shown), the limiting block body 2010 is convexly provided with a first limiting strip 2011 and a second limiting strip 2012, and both the first limiting strip 2011 and the second limiting strip 2012 extend along the second direction (i.e., Figure 4 the Y direction shown), and along the second direction, both the first limiting strip 2011 and the second limiting strip 2012 include a first end and a second end.

[0090] Exemplarily, referring to Figure 6a and Figure 6b and combining with Figure 4 , along the width direction of the rotating block 202 (i.e., Figure 4 the L direction shown), both sides of the rotating block 202 are provided with recesses. For the convenience of description, one side of the recess is called the first recess 2020, and the other side is called the second recess 2021. The first recess 2020 includes a first wall 2022 of the first recess and a second wall 2023 of the first recess. The first wall 2022 and the second wall 2023 of the first recess are arranged at an angle and are arc-connected, so that the second wall 2023 of the first recess protrudes from the first wall 2022 of the first recess along the width direction of the rotating block 202.

[0091] The second recess 2021 also includes a first wall 2024 of the second recess and a second wall 2025 of the second recess. The first wall 2024 and the second wall 2025 of the second recess are arranged at an angle and are arc-connected, so that the second wall 2025 of the second recess protrudes from the first wall 2024 of the second recess along the width direction of the rotating block 202.

[0092] Exemplarily, referring to Figure 6a and Figure 6b and combining with Figure 1a and Figure 4 , in the locked state, the rotating block 202 extends along the third direction (i.e., Figure 4 the a direction shown), the second end 2014 of the first limiting strip contacts the first recess 2020 and abuts against the first wall 2022 of the first recess, so that the first limiting strip 2011 is limited in the first recess 2020 (refer to Figure 6a ), the first end 2015 of the second limiting strip contacts the second recess 2021 and abuts against the first wall 2024 of the second recess, so that the second limiting strip 2012 is limited in the second recess 2021 (refer to Figure 6b ).

[0093] Exemplarily, in the unlocked state (refer to Figure 7), the rotating block 202 extends along the second direction (i.e., Figure 4 the Y direction shown), and along the first direction (i.e., Figure 4 the X direction shown), the rotating block 202 is located above the limiting block 201 and is parallel to it. Specifically, along the width direction of the rotating block 202 (i.e., Figure 4 the a direction shown), both sides are parallel to the first limiting strip 2011 and the second limiting strip 2012 respectively.

[0094] In this way, when the rotating block 202 rotates reversely by a first angle around the first direction, under the limitation of the second end 2014 of the first limiting strip and the first end 2015 of the second limiting strip, the rotating block 202 can no longer rotate reversely, that is, it cannot rotate excessively, preventing it from hitting the small parts on the PCB 300 and causing damage to them. Because at this time, the first wall 2022 of the first recess abuts against the second end 2014 of the first limiting strip, and the first wall 2024 of the second recess abuts against the first end 2015 of the second limiting strip.

[0095] Similarly, when the rotating block 202 rotates reversely by a first angle around the first direction, under the limitation of the second end 2014 of the first limiting strip and the first end 2015 of the second limiting strip, the rotating block 202 can no longer rotate forward, that is, it cannot be converted from the locked state to the unlocked state, because at this time, the second wall 2023 of the first recess is stuck by the second end 2014 of the first limiting strip, and the second wall 2025 of the second recess is stuck by the first end 2015 of the second limiting strip.

[0096] Exemplarily, referring to Figure 4 and Figure 5 and combining with Figure 2 , the rotating block 202 further includes a sliding rod 203 extending along the first direction (i.e., Figure 4 the X direction shown), the limiting block 201 further includes an extension 2017 extending along the first direction, the extension 2017 is provided with a receiving hole 2018, the sliding rod 203 passes through the limiting block body 2010 and enters the receiving hole 2018, and is connected to the extension 2017 by a bolt 204. An elastic member 205 is attached inside the receiving hole 2018, and the elastic member 205 is sleeved on the sliding rod 203.

[0097] Exemplarily, the elastic member 205 is a spring. By providing the spring, the friction force when the rotating block 202 rotates relative to the limit block 201 around the first direction is increased. In this way, when the rotating block 202 rotates in the opposite direction by a first angle around the first direction, the friction force between the rotating block 202 and the limit block 201 is increased by the spring. Therefore, without the action of external force, the rotating block 202 can no longer continue to rotate in the opposite direction, that is, it can no longer rotate excessively, so as to prevent the small parts on the PCB 300 from being hit and damaged. Similarly, when the rotating block 202 rotates in the opposite direction by a first angle around the first direction, the rotating block 202 can no longer rotate back in the positive direction, that is, it can no longer be converted from a locked state to an unlocked state.

[0098] Exemplarily, two ear blocks 206 are further provided on a side of the rotating block 202 away from the limiting block 201 . The two ear blocks 206 are spaced apart along the width direction of the rotating block 202 so that light from a sensor described later can pass through the gap between the two ear blocks 206 .

[0099] For example, reference Figures 1 to 4 The state switching mechanism includes an automatic unlocking mechanism 400, which includes a first toggle member 401 and a first driving unit 402. The number of the first toggle members 401 corresponds to the number of the above-mentioned rotating mechanism 200. The first toggle member 401 is a first driving unit 402. Figure 1a When unlocking is required, the first lever 4010 extends in the second direction (ie, the X direction shown in FIG. Figure 1a The first lever 4010 is located on the right side of the rotating block 202 , and along the first direction, the first lever 4010 is located above the limiting block 201 and does not contact the limiting block 201 .

[0100] Exemplarily, the first driving portion 402 includes a first driving member 4020 and a first connecting member 4021. Along the first direction, the first connecting member 4021 is connected to the first lever 4010. Along the second direction, the first driving member 4020 is connected to the first connecting member 4021. The first driving member 4020 is used to drive the first connecting member 4021 to move leftward along the second direction, so as to drive the first lever 4010 to move leftward along the second direction (i.e., Figure 1a d direction as shown), so that the first lever 4010 contacts the rotating block 202. As the first lever 4010 continuously moves to the left along the second direction, the rotating block 202 also continuously moves forward (i.e., Figure 4 g direction as shown) until it is rotated positively around the first direction by a first angle, so that the rotating block 202 is converted from the locked state to the unlocked state (i.e., from Figure 4 The state shown is converted to Figure 7 status shown).

[0101] Exemplarily, the first driving member 4020 is a cylinder, but is not limited thereto. Any mechanism capable of driving the first connecting member 4021 to perform a linear motion in the second direction, such as a motor, etc., is acceptable. The first connecting member 4021 is a first connecting plate, and the first connecting plate is a rectangular plate.

[0102] Exemplarily, referring to Figures 1 to 4 and combining with Figure 7 , in the locked state, the rotating block 202 extends in the third direction (i.e., the Figure 4 a direction shown), and forms a first angle (i.e., the Figure 4 α shown) with respect to the above-mentioned limiting block body 2010. The rotating block 202 presses against the PCB 300 in the first direction (i.e., the Figure 4 X direction shown); in the unlocked state, the rotating block 202 extends in the second direction (i.e., the Figure 7 Y direction shown), and is located above the limiting block body 2010 in the first direction. The rotating block 202 does not contact the PCB 300.

[0103] With the above technical solution, when the painting of the PCB 300 is completed, the PCB 300 needs to be taken out from the placement groove 101. At this time, the automatic unlocking mechanism 400 converts the rotating block 202 from the locked state to the unlocked state, that is, the rotating block 202 changes from pressing against the PCB 300 in the first direction to not contacting the PCB 300. At this time, the rotating block 202 does not contact the PCB 300, so it does not fix the PCB 300. There is no need for manual rotation of the rotating block 202 to make the rotating block 202 rotate away to not contact the PCB 300, saving time and labor costs. At the same time, the machine operation is more standard, and the uncertainty brought by manual operation can be avoided.

[0104] Exemplarily, referring to Figure 1 , Figure 1a and Figure 2 , the automatic unlocking mechanism 400 further includes a third driving mechanism 403. The third driving mechanism 403 includes a third driving member 4030, a third connecting member 4031, and a fifth connecting member 4034. Along the first direction (i.e., the Figure 1 X direction shown), the output end of the third driving member 4030 passes through the fifth connecting member 4034 and is connected to the third connecting member 4031. The fifth connecting member 4034, the third connecting member 4031, and the first connecting member 4021 are sequentially arranged at intervals in the first direction (i.e., the Figure 1 X direction shown). There are four support columns 4035 arranged at intervals along the outer edge of the fifth connecting member 4034 between the fifth connecting member 4034 and the third connecting member 4031, but is not limited thereto. It can also be five, six, seven, etc.

[0105] Exemplarily, the third driving member 4030 is a cylinder, but is not limited thereto. Any mechanism that can drive the third connecting member 4031 to perform a linear motion in the first direction is acceptable, such as a motor. The third connecting member 4031 is a third connecting plate, the third connecting plate is a rectangular plate, the fifth connecting member 4034 is a fifth connecting plate, and the fifth connecting plate is a rectangular plate.

[0106] Exemplarily, a first sliding rail 4032 is provided on the surface of the third connecting member 4031 facing the first connecting member 4021, and a first sliding block 4033 is provided on the surface of the first connecting member 4021 facing the third connecting member 4031. Driven by the first driving member 4020, the first sliding block 4033 is configured to move along the first sliding rail 4032, so that the first connecting member 4021 can move relative to the third connecting member 4031 in the second direction.

[0107] That is to say, the first connecting member 4021 is connected to the third connecting member 4031 in a slidable manner in the second direction.

[0108] Exemplarily, the third driving member 4030 is configured to drive the first lever 4010 to move in the first direction, so that the first lever 4010 contacts or does not contact the rotating block 202 in the first direction.

[0109] Specifically, when the above unlocking operation is completed, at this time, the third driving member 4030 can drive the third connecting member 4031 to move upward in the first direction (i.e., move in the direction close to the fifth connecting member 4034, that is, Figure 1 the b direction shown), to drive the first connecting member 4021 to move upward in the first direction, thereby driving the first lever 4010 to move upward in the first direction (i.e., move in the direction away from the PCB 300), so that the first lever 4010 moves in the first direction to not contact the rotating block 202. At this time, without the interference of the first lever 4010, the fixture 100 can drive the PCB 300 to continue moving to the next production line or at this time it is convenient to take out the PCB 300 from the placement slot 101 of the fixture 100, and then perform the painting work on the next batch of PCBs 300.

[0110] When the above unlocking operation needs to be performed, the third driving member 4030 can drive the third connecting member 4031 to move downward in the first direction (i.e., move in the direction away from the fifth connecting member 4034, that is, Figure 1c direction as shown), so as to drive the first connecting member 4021 to move downward along the first direction, thereby driving the first lever 4010 to move downward along the first direction (that is, to move in the direction close to PCB300), so that the first lever 4010 moves along the first direction to the left side of the rotating block 202 and contacts the rotating block 202, so that the first lever 4010 can drive the rotating block 202 to rotate positively around the first direction to a first angle, that is, the above-mentioned unlocking operation can be performed.

[0111] Exemplarily, the automatic unlocking mechanism 400 further includes a bracket 404, the bracket 404 includes a first plate 4040 and a second plate 4041, the first plate 4040 is located on the ground and is arranged along the second direction (ie Figure 1 The second plate 4041 includes two plates spaced apart along the second direction, each of the two second plates 4041 includes a first portion 4042 and a second portion 4043, one end of the first portion 4042 is connected to the first plate 4040, the other end of the first portion 4042 is connected to the second portion 4043, the first portion 4042 and the second portion 4043 are arranged at 90°, and the fifth connecting member 4034 is arranged between the two second portions 4043.

[0112] For example, reference Figures 1 to 2 and Figure 10 The outer edge of the clamp 100 is also provided with a positioning hole 102, and the first connecting member 4021 is provided with a positioning column 103 corresponding to the positioning hole 102 on a side facing the clamp 100. In this way, when the third driving member 4030 drives the first connecting member 4021 to move in a direction close to the PCB 300, it can move to a set position, preventing the first toggle member 401 from being unable to contact the rotating block 202 due to an incorrect movement direction.

[0113] Exemplarily, a sensor is provided on the first connecting member 4021, and the sensor is used to detect whether the rotating block 202 is in a locked state or an unlocked state.

[0114] Specifically, the light emitted by the sensor can pass through the gap between the two ear blocks 206 to determine the angle between the ear block 206 and the limit block 201. If the angle between the ear block 206 and the limit block 201 is the first angle, it means that the rotating block 202 is in a locked state at this time, preventing the rotating block 202 from excessively rotating and causing damage to the PCB300, or not rotating into place and not completely fixing the PCB300, thereby affecting the painting work described later.

[0115] Similarly, the light emitted by the sensor can pass through the gap between the two ear blocks 206 to determine the angle between the ear block 206 and the limit block 201. If the angle between the ear block 206 and the limit block 201 is 0°, it indicates that the rotating block 202 is in the unlocked state at this time, preventing the rotating block 202 from not rotating in place completely and not leaving the PCB 300 completely, which affects the removal of the PCB 300. At this time, if the PCB 300 is forcibly removed, it will cause damage to the PCB 300.

[0116] Exemplarily, referring to Figures 8 to 11 and combining with Figure 1 and Figure 1a , the state switching mechanism further includes an automatic locking mechanism 500. The difference between the automatic locking mechanism 500 and the above-mentioned automatic unlocking mechanism 400 lies in the positions and movement trajectories of the first toggle member 401 and the second toggle member 501.

[0117] Specifically, referring to Figure 2 , along the second direction (such as the Y direction shown in Figure 1a ), the first toggle member 401 is located on the right side of the rotating block 202. When unlocking work needs to be performed, along the first direction (such as the X direction shown in Figure 1a ), the first toggle member 401 is located above the limit block 201 and does not contact the limit block 201. The first driving member 4020 drives the first connecting member 4021 to move leftward along the second direction, so as to drive the first lever 4010 to move leftward along the second direction (i.e., the d direction shown in Figure 1a ), so that the first lever 4010 contacts the rotating block 202. As the first lever 4010 continuously moves leftward along the second direction, the rotating block 202 also continuously rotates positively around the first direction until it rotates positively around the first direction by a first angle, so that the rotating block 202 is converted from the locked state to the unlocked state (i.e., from the state shown in Figure 4 to the state shown in Figure 7 ).

[0118] When locking work needs to be performed, along the second direction, the second toggle member 501 is located on the left side of the rotating block 202. Along the first direction, the second toggle member 501 is located above the limit block 201 and does not contact the limit block 201. The second driving member 5020 drives the second connecting member 5021 to move forward along the fourth direction (such as the e direction shown in Figure 11 ), so that the second toggle member 501 moves forward along the fourth direction to contact the rotating block 202. As the second toggle member 501 continuously moves forward along the fourth direction, the rotating block 202 also continuously rotates positively around the first direction until it rotates reversely around the first direction by a first angle, so that the rotating block 202 is converted from the unlocked state to the locked state. The fourth direction (such as the Z direction shown in Figure 8 ) is perpendicular to the second direction (such as the Y direction shown in Figure 8 ).

[0119] Another difference is that the second connecting member 5021 is connected to the fourth connecting member 5031 in a slidable manner along the fourth direction, and the second driving member 5020 is connected to the second connecting member 5021 along the fourth direction, and the second driving member 5020 is used to drive the second connecting member 5021 to move forward along the fourth direction, so as to drive the second toggle member 501 to move forward along the fourth direction (such as Figure 11 e direction as shown), so that the second toggle member 501 contacts the rotating block 202. As the second toggle member 501 continuously moves forward along the fourth direction, the rotating block 202 also continuously moves in the reverse direction around the first direction (i.e. Figure 4 f direction as shown in FIG. 1 ) until it is rotated in the opposite direction around the first direction by a first angle, so that the rotating block 202 is converted from the unlocked state to the locked state (i.e., from Figure 7 The state shown is converted to Figure 4 status shown).

[0120] Exemplarily, the second shifting member 501 is a second shifting rod, and the second driving member 5020 is a cylinder, but not limited thereto, any mechanism that can drive the second connecting member 5021 to perform linear motion along the fourth direction can be used, such as a motor, etc. The second connecting member 5021 is a second connecting plate, which is a rectangular plate, and the fourth connecting member 5031 is a fourth connecting plate, which is a rectangular plate.

[0121] And the bracket of the automatic locking mechanism 500 is different from that of the automatic unlocking mechanism.

[0122] Specifically, the bracket of the automatic locking mechanism 500 is composed of a bracket along the fourth direction (i.e. Figure 8 The sixth connecting member 405 extending in the Z direction (shown in FIG. 1 ) is connected to the four connecting members extending in the first direction (ie, Figure 8 The fourth driving member 5030 is connected to the fourth connecting member 5031 through the sixth connecting member.

[0123] In addition, the structure of the automatic locking mechanism 500 is the same as that of the above-mentioned automatic unlocking mechanism 400. Specifically, the second driving part 502 of the automatic locking mechanism 500 has the same structure as the first driving part of the automatic unlocking mechanism 400, and the fourth driving mechanism 503 of the automatic locking mechanism 500 has the same structure as the third driving mechanism of the automatic unlocking mechanism 400, which will not be repeated in the embodiments of the present application.

[0124] The first direction (i.e. Figure 2 The X direction shown) and the second direction (i.e. Figure 2The first direction and the second direction intersect each other, and the second direction and the fourth direction (ie, Figure 2 The Z direction shown in the figure) are perpendicular to each other, and the third direction (i.e. Figure 4 The a direction shown in the figure) intersects with the first direction and the second direction respectively.

[0125] In summary, reference Figures 1 to 11 When the PCB 300 needs to be sprayed with paint, the PCB 300 needs to be placed in the placement slot 101, and the fourth driving member 5030 drives the fourth connecting member 5031 to move downward along the first direction (ie Figure 8 c direction as shown), so as to drive the second connecting member 5021 to move downward along the first direction, thereby driving the second driving member 501 to move downward along the first direction (that is, to move in the direction close to PCB300), so that the second driving member 501 moves along the first direction until it contacts the rotating block 202, so that the second driving member 501 can drive the rotating block 202 to rotate in the opposite direction around the first direction by a first angle, that is, to be able to perform the locking work described later.

[0126] Exemplarily, the fourth driving member 5030 is a cylinder, but is not limited thereto. Any mechanism that can drive the fourth connecting member 5031 to perform linear motion along the first direction, such as a motor, etc., may be used.

[0127] Then, the automatic locking mechanism 500 converts the rotating block 202 from the unlocked state to the locked state, that is, the rotating block 202 is converted from not contacting the PCB 300 to pressing the PCB 300 along the first direction.

[0128] Specifically, since the second driving member 5020 is connected to the second connecting member 5021, and the second connecting member 5021 is connected to the second toggle member 501, the second driving member 5020 can drive the second connecting member 5021 to move forward along the fourth direction (ie Figure 11 e direction as shown), thereby driving the second toggle member 501 to move forward in the fourth direction (i.e., move in the direction close to PCB 300), so that the second toggle member 501 contacts the rotating block 202. As the second toggle member 501 continues to move forward in the fourth direction, the rotating block 202 also continuously moves in the reverse direction around the first direction (i.e., Figure 4 f direction as shown in FIG. 1 ) until it is rotated in the opposite direction around the first direction by a first angle, so that the rotating block 202 is converted from the unlocked state to the locked state (i.e., from Figure 7 The state shown is converted to Figure 4 status shown).

[0129] When the second driving member 5020 drives the second connecting member 5021 to move in the fourth direction, the second slider 5033 provided on the second connecting member 5021 can move synchronously along the second slide rail 5032 provided on the fourth connecting member 5031, so that the second connecting member 5021 can move relative to the fourth connecting member 5031 in the fourth direction.

[0130] At this time, the rotating block 202 presses the PCB 300 along the first direction, thereby fixing the PCB 300. There is no need for manual rotation of the rotating block 202 to fix the PCB 300, saving time and labor costs. At the same time, the machine operation is more standard, which can avoid the uncertainty brought by manual operation, so that the fixing effect is better.

[0131] After the above-mentioned locking work is completed, the fourth driving member 5030 can drive the fourth connecting member 5031 to move upward along the first direction (i.e., Figure 8 the b direction shown), so as to drive the second connecting member 5021 to move upward along the first direction, thereby driving the second toggling member 501 to move upward along the first direction (i.e., move in the direction away from the PCB 300), so that the second toggling member 501 moves along the first direction to a position where it does not contact the rotating block 202. At this time, without the interference of the second toggling member 501, the fixture 100 can drive the PCB 300 to continue moving to the next production line, such as for painting work.

[0132] After the painting of the PCB 300 is completed, the fixture 100 drives the PCB 300 to continue moving forward to the automatic unlocking mechanism 400. When unlocking work is required, the third driving member 4030 can drive the third connecting member 4031 to move downward along the first direction (i.e., Figure 1 the c direction shown), so as to drive the first connecting member 4021 to move downward along the first direction, thereby driving the first toggling member 401 to move downward along the first direction (i.e., move in the direction close to the PCB 300), so that the first toggling member 401 moves along the first direction to the right side of the rotating block 202 and contacts the rotating block 202, so that the first toggling member 401 can drive the rotating block 202 to rotate positively by a first angle around the first direction, that is, the unlocking work described later can be performed.

[0133] Then, the automatic unlocking mechanism 400 converts the rotating block 202 from the locked state to the unlocked state, that is, the rotating block 202 changes from pressing the PCB 300 along the first direction to not contacting the PCB 300.

[0134] Specifically, the first driving member 4020 drives the first connecting member 4021 to move leftward along the second direction (i.e., Figure 1ain the d direction shown in the figure), to drive the first lever 4010 to move leftward in the second direction, so that the first lever 4010 contacts the rotating block 202. As the first lever 4010 continuously moves leftward in the second direction, the rotating block 202 also continuously rotates positively around the first direction (i.e., Figure 4 in the g direction shown in the figure), until it rotates positively around the first direction by a first angle, so that the rotating block 202 is converted from the locked state to the unlocked state (i.e., from Figure 4 the state shown in the figure is converted to Figure 7 the state shown in the figure).

[0135] When the first driving member 4020 drives the first connecting member 4021 to move leftward in the second direction, the first slider 4033 provided on the first connecting member 4021 can move synchronously along the first sliding rail 4032 provided on the third connecting member 4031, so that the first connecting member 4021 can move relative to the third connecting member 4031 in the second direction.

[0136] At this time, the rotating block 202 does not contact the PCB 300, so it does not fix the PCB 300. There is no need for manual rotation of the rotating block 202 to make the rotating block 202 rotate away from the PCB 300, saving time and labor costs. At the same time, the machine operation is more standard, and the uncertainty brought by manual operation can be avoided.

[0137] When the above unlocking work is completed, at this time, the third driving member 4030 can drive the third connecting member 4031 to move upward in the first direction (i.e., Figure 1 in the b direction shown in the figure), to drive the first connecting member 4021 to move upward in the first direction, thereby driving the first lever 4010 to move upward in the first direction (i.e., the direction away from the PCB 300), so that the first lever 4010 moves in the first direction until it does not contact the rotating block 202. At this time, without the interference of the first lever 4010, the fixture 100 can drive the PCB 300 to continue to move to the next production line or it is convenient to take out the PCB 300 from the placement groove 101 of the fixture 100 at this time, and then perform the painting work on the next batch of PCB 300.
