Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of component processing and assembling, in particular to an automatic locking device and an automatic assembling equipment. BACKGROUND

[0002] In the field of component processing and assembling, such as the assembling industry of smart phones, it is usually required to implant small parts onto workpieces. At present, when implanting small parts onto workpieces, multiple workstations and more workers need to be used to cooperate to complete the assembling of small parts and workpieces. However, the above-mentioned working mode has the problems of large number of workstations and high labor cost. In addition, when assembling small parts to workpieces, if it is required to lock screws from the side of small parts, the small parts are usually directly placed on the workpieces and then the two are locked, but there is usually no structure for positioning small parts on the workpiece, and this method is easy to cause the position of small parts on the workpiece to change. In the field of precise assembling and processing, this situation often leads to that the assembling result does not meet the requirements, and the workpiece after locking is completed does not meet the requirements, which needs to be reworked or directly scrapped.

The transfer assembly 13 is arranged adjacent to the film tearing assembly 12. The vision assembly 14 is arranged on the transfer assembly 13, and is used to position the small piece 2002 on the film tearing assembly 12. The adjusting assembly 15 is arranged on the transfer assembly 13 and is arranged adjacent to the vision assembly 14, and the adjusting assembly 15 is used to cooperate with the vision assembly 14 to adsorb the small piece 2002 and move the small piece 2002 to the jig assembly 22 under the driving of the transfer assembly 13. The correction assembly 16 is arranged adjacent to the transfer assembly 13, and is used to detect the position of the small piece 2002 adsorbed by the adjusting assembly 15 to adjust the position of the small piece 2002 by the adjusting assembly 15. Among them, the film tearing assembly 12, the transfer assembly 13 and the correction assembly 16 are arranged on the locking platform 70, and the fixing frame 11 and the film tearing assembly 12 can be connected to form a feeder mechanism.

[0144] Therefore, in order to accurately place the small piece 2002 on the jig assembly 22 and avoid the assembly of the small piece 2002 and the workpiece from being defective, the fixing frame 11 and the film tearing assembly 12 of the small piece feeding mechanism 10 cooperate to provide the small piece 2002, the vision assembly 14 and the adjusting assembly 15 are driven by the transfer assembly 13 to move above the film tearing assembly 12, the vision assembly 14 positions the small piece 2002 on the film tearing assembly 12, so that the adjusting assembly 15 can accurately adsorb the small piece 2002, after the adjusting assembly 15 adsorbs the small piece 2002, the vision assembly 14 and the adjusting assembly 15 are driven by the transfer assembly 13 to move above the correction assembly 16, the correction assembly 16 detects the position of the small piece 2002 adsorbed by the adjusting assembly 15, so that the adjusting assembly 15 adjusts the position of the small piece 2002, after the adjusting assembly 15 adjusts the position of the small piece 2002, the vision assembly 14 and the adjusting assembly 15 are driven by the transfer assembly 13 to move above the jig assembly 22, the vision assembly 14 positions the jig assembly 22 again, the adjusting assembly 15 adjusts the position of the small piece 2002 again under the cooperation of the vision assembly 14 and accurately places the adjusted small piece 2002 on the jig assembly 22, effectively avoiding the assembly of the small piece 2002 and the workpiece from being defective, and facilitating to improve the production efficiency.

[0145] It should be noted that when the adjusting assembly 15 adsorbs the small piece 2002 from the film tearing assembly 12, since the position of the small piece 2002 on the film 2004 is not fixed, there may be defects such as deviation, tilt, and warping, and therefore the vision assembly 14 needs to position the small piece 2002, so that the adjusting assembly 15 can accurately adsorb the small piece 2002 according to the position of the small piece 2002. After the adjusting assembly 15 adsorbs the small piece 2002, since the adjusting assembly 15 adsorbs the small piece 2002 according to the position of the small piece 2002, the position of the small piece 2002 on the adjusting assembly 15 also has defects such as deviation, tilt, and warping, and therefore the correction assembly 16 needs to detect the position of the small piece 2002, so that the adjusting assembly 15 adjusts the position of the small piece 2002, so that the position of the small piece 2002 on the adjusting assembly 15 meets the predetermined position. When the adjusting assembly 15 places the small piece 2002 on the jig assembly 22, since the jig assembly 22 is jacked up by the jacking mechanism 40, the jig assembly 22 may have defects such as deviation and tilt when it is placed on the sliding assembly 21 again, and therefore the adjusting assembly 15 needs to position the jig assembly 22 again, so that the adjusting assembly 15 adjusts the position of the small piece 2002 again according to the position of the jig assembly 22, so that the adjusting assembly 15 can accurately place the adjusted small piece 2002 on the jig assembly 22.

[0146] Specifically, please refer to Figure 5The film tearing assembly 12 comprises a frame 121, a platform surface 121a, a movement cavity 121b, a containing groove 121c and a guide 122. The frame 121 is arranged on the locking platform 70, one side of the frame 121 is arranged adjacent to the fixed frame 11 and connected with the fixed frame 11 or arranged spaced apart from the fixed frame 11, the other side of the frame 121 is arranged adjacent to the guide 122 and arranged spaced apart from the guide 122 or fixedly connected with the guide 122. The platform surface 121a, the movement cavity 121b and the containing groove 121c are sequentially arranged on the frame 121 and located between the fixed frame 11 and the guide 122, the platform surface 121a is used for laying the material belt 2001 provided by the fixed frame 11, so that the material belt 2001 enters the movement cavity 121b through the platform surface 121a, after the material belt 2001 passes through the movement cavity 121b, the protective film 2006 of the material belt 2001 is folded back by the upper cavity wall 121d of the movement cavity 121b and separated from the negative film 2004, the negative film 2004 and the small piece 2002 of the material belt 2001 after the protective film 2006 is torn off are laid on the groove bottom of the containing groove 121c, so that the adjusting assembly 15 can adsorb the small piece 2002 on the negative film 2004 from the containing groove 121c, and the negative film 2004 after the small piece 2002 is adsorbed is guided to a recycling position under the action of the guide 122.

[0147] The moving direction of the protection film 2006 which is turned back by the upper cavity wall 121d of the moving cavity 121b is parallel to the moving direction of the material belt 2001 and is above the material belt 2001, the protection film 2006 which is turned back by the upper cavity wall 121d of the moving cavity 121b needs to be conveyed into the container such as the recovery box below, but if the moving direction of the protection film 2006 is directly changed from the horizontal direction to downward movement, the protection film 2006 will interfere with the material belt 2001 below, therefore in an embodiment, the film tearing assembly 12 further comprises a deflection unit 123 and a deflection driving member (not shown in the figure), the deflection unit 123 is arranged on the frame 121 and above the platform surface 121a, for changing the moving direction of the protection film 2006 which is turned back by the upper cavity wall 121d of the moving cavity 121b, avoiding the interference between the torn protection film 2006 and the material belt 2001 on the platform surface 121a during recovery, thereby affecting the normal supply of the small pieces 2002. The deflection driving member is arranged on the frame 121 and below the platform surface 121a, for driving the protection film 2006 after the moving direction is changed by the deflection unit 123 to move, so as to move the protection film 2006, on the one hand, the torn protection film 2006 is recovered, on the other hand, the protection film 2006 is separated from the base film 2004, and at the same time, power is provided for the supply of the entire material belt 2001. In addition, the two groove walls of the accommodation groove 121c can also limit the left and right of the base film 2004, avoiding the movement of the base film 2004 from shifting when the base film 2004 is pulled by the protection film 2006, thereby causing the adjustment assembly 15 to be unable to effectively adsorb the small pieces 2002, which is beneficial to improve the adsorption yield. When the adjustment assembly 15 adsorbs the small pieces 2002, the situation that the small pieces 2002 and the base film 2004 are connected relatively firmly and drive the base film 2004 to move upward may also occur, through the upper cavity wall 121d of the moving cavity 121b, the base film 2004 can also be limited up and down when the above-mentioned situation occurs, avoiding the base film 2004 from being taken away by the adjustment assembly 15, and ensuring the normal supply of the small pieces 2002.

[0148] The deflection unit 123 comprises a first deflection shaft 1231, a second deflection shaft 1232 and a third deflection shaft 1233. The first deflection shaft 1231 is rotatably arranged on the frame 121 above the platform surface 121a, and the axial direction of the first deflection shaft 1231 is perpendicular to the moving direction of the material belt 2001 to smoothly receive the deflected protective film 2006. The second deflection shaft 1232 and the third deflection shaft 1233 are both rotatably arranged on the frame 121. The second deflection shaft 1232 is above the platform surface 121a, and the third deflection shaft 1233 is above the side of the platform surface 121a. The second deflection shaft 1232 is above the third deflection shaft 1233. The axial direction of the second deflection shaft 1232 is arranged at an acute angle with the axial direction of the first deflection shaft 1231 to change the moving direction of the protective film 2006 passing through the second deflection shaft 1232. The axial direction of the third deflection shaft 1233 is parallel to the moving direction of the material belt 2001 to change the moving direction of the protective film 2006 passing through the third deflection shaft 1233 again. After passing through the third deflection shaft 1233, the moving direction of the protective film 2006 is perpendicular to the moving direction of the material belt 2001 and passes through the side of the material belt 2001, thereby avoiding interference with the material belt 2001. The protective film 2006 passing through the third deflection shaft 1233 is connected with a deflection driving member to move under the pulling action of the deflection driving member. The deflection driving member provides the power for the movement of the protective film 2006. In this way, by arranging the first deflection shaft 1231, the second deflection shaft 1232 and the third deflection shaft 1233, and arranging the axial direction of the second deflection shaft 1232 at an acute angle with the axial direction of the first deflection shaft 1231, the moving direction of the protective film 2006 is changed to avoid interference between the moving direction of the deflected protective film 2006 and the moving direction of the material belt 2001. Obviously, the deflection unit 123 can also comprise more deflection shafts to change the moving direction of the protective film 2006.

[0149] In some embodiments, the fixed frame 11 cooperates with the film-removing assembly 12 to provide the implementation process of the small pieces 2002 as follows: first, the roll 2000 of the material tape 2001 is placed on the fixed frame 11, and one end of the material tape 2001 passes through the platform surface 121a and the movement cavity 121b. Then, the protective film 2006 on the material tape 2001 passing through the movement cavity 121b is folded back by the upper cavity wall 121d of the movement cavity 121b and separated from the negative film 2004, and the folded-back protective film 2006 passes through the first deflection shaft 1231, the second deflection shaft 1232 and the third deflection shaft 1233 in sequence, and finally connects with the deflection driving member. Then, the negative film 2004 is placed on the groove bottom of the accommodating groove 121c, and one end of the negative film 2004 is placed on the guide member 122, at this time, the small pieces 2002 are exposed on the negative film 2004, and the adjusting assembly 15 and the visual assembly 14 can cooperate to adsorb the small pieces 2002 from the negative film 2004. Then, after the small pieces 2002 on the groove bottom of the accommodating groove 121c are adsorbed, the deflection driving member pulls the protective film 2006 to move, and the protective film 2006 moves under the pulling of the deflection driving member and pulls the negative film 2004 to move forward and separate from the negative film 2004 by relying on the adhesion between the protective film 2006 and the negative film 2004, and the negative film 2004 adsorbing the small pieces 2002 moves along the guide member 122 to the recycling position until a predetermined number of small pieces 2002 are exposed on the groove bottom of the accommodating groove 121c. Thus, the small pieces 2002 are provided in a cycle.

[0150] In an embodiment, the deflection driving member can include a motor (not shown in the figure) and a winding drum (not shown in the figure), the winding drum is detachably connected with the motor, the motor drives the winding drum to rotate to wind the protective film 2006 on the winding drum, so as to pull the protective film 2006 to rotate. When the winding drum is fully wound with the protective film 2006, a new winding drum can be replaced. Alternatively, the deflection driving member can also be composed of two friction wheels meshing with each other, the two friction wheels meshing with each other clamp the protective film 2006 to drive the protective film 2006 to move and guide the protective film 2006 to the designated position.

[0151] In an embodiment, the second deflection shaft 1232 is obliquely arranged, the lower end of the second deflection shaft 1232 is connected with the third deflection shaft 1233, the included angle between the axial direction of the second deflection shaft 1232 and the axial direction of the first deflection shaft 1231 is 45°, and the included angle between the axial direction of the second deflection shaft 1232 and the axial direction of the third deflection shaft 1233 is also 45°. In this way, by arranging the second deflection shaft 1232 to be connected with the third deflection shaft 1233 and limiting the included angle between the axial directions of the second deflection shaft 1232 and the third deflection shaft 1233 to be 45°, the movement direction of the protective film 2006 is conveniently and smoothly changed. Obviously, the included angle between the axial direction of the second deflection shaft 1232 and the axial direction of the first deflection shaft 1231 can also be 10°, 15°, 30°, 60°, 75°, 80°, etc.

[0152] In an embodiment, referring to Figure 4 , the side of the guide 122 facing away from the frame 121 is arc-shaped, for guiding the sheet 2004 to a recycling position.

Obviously, the number of the flybar mechanisms can also be one, two, three, five or more.

The adjusting drive 151 is arranged on the transfer assembly 13, and the suction accessory 152 is connected to the adjusting assembly 15. The suction accessory 152 is used for adsorbing the small piece 2002, and can move along a first direction and rotate about the first direction under the driving of the adjusting drive 151. In this way, the adjusting assembly 15 can drive the suction accessory 152 to move to take and place the small piece 2002, and can also adjust the position of the suction accessory 152 to facilitate accurate taking and placing of the small piece 2002. In order to facilitate description and understanding, the first direction is defined as the Z-axis direction as shown in Figure 1 , the second direction is defined as the X-axis direction as shown in Figure 1 , and the third direction is defined as the Y-axis direction as shown in Figure 1 .

[0155] In an embodiment of the present application, referring to Figure 4The transfer assembly 13 comprises a first sliding unit 131 and a second sliding unit 132. The number of the first sliding units 131 is two, the two first sliding units 131 are arranged at intervals and located at two sides of the film tearing assembly 12, the two first sliding units 131 are arranged on the locking platform 70, and the two ends of the second sliding unit 132 are connected with the two first sliding units 131 respectively.

In this way, by arranging the two first sliding units 131, the balance of the second sliding unit 132, the adjusting assembly 15 and the visual assembly 16 during movement is facilitated, and the small piece 2002 is accurately taken and placed. The first sliding unit 131 and the second sliding unit 132 can be linear modules. The film tearing assembly 12 is located at the middle position of the two first sliding units 131.

[0156] It can be understood that in other embodiments, the number of the first sliding units 131 can also be one, and the transfer assembly 13 further comprises a guide rail (not shown) arranged at intervals with the first sliding unit 131, the guide rail is arranged on the locking platform 70, and the two ends of the second sliding unit 132 are connected with the first sliding unit 131 and the guide rail respectively.

[0157] In the embodiments of the present application, please refer to Figure 6 The visual assembly 14 comprises a first image sensor 141 and a first light source 142 arranged on the second sliding unit 132, the first image sensor 141 and the first light source 142 are coaxially arranged, the first image sensor 141 is used to acquire the image of the small piece 2002, and the first light source 142 is used to emit light so that the first image sensor 141 can acquire the image of the small piece 2002 more clearly. The first image sensor 141 can be an industrial camera or other image acquisition device capable of acquiring the image of the small piece 2002.

[0158] In the embodiments of the present application, please refer to Figure 6 The correction assembly 16 comprises a second image sensor 161 and a second light source 162 arranged adjacent to the transfer assembly 13 and the film tearing assembly 12, the second image sensor 161 is arranged on the locking platform 70 and located at the middle position of the two first sliding units 131, the second image sensor 161 is used to acquire the image of the small piece 2002, and the second light source 162 is used to emit light so that the second image sensor 161 can acquire the image of the small piece 2002 more clearly.

[0159] In the embodiments of the present application, please refer toFigure 2 The workpiece loading / unloading mechanism 30 may include a three-axis motion module 31 and a pick-and-place component 32. The three-axis motion module 31 is mounted on the locking platform 70 via a support frame 80. The pick-and-place component 32 is connected to the three-axis motion module 31 and is used to move along a first direction, a second direction, and a third direction under the drive of the three-axis motion module 31 to place the workpiece on the fixture assembly 22, or to remove the assembled workpiece and small parts 2002 from the fixture assembly 22 and unload them. The three-axis motion module 31 may be a three-axis linear module or a robot, and the pick-and-place component 32 may be a robot gripper, a suction nozzle, or other objects, which can be specifically set according to the type of workpiece.

[0160] In the embodiments of this application, please refer to Figure 7 and Figure 8 The fixture assembly 22 includes a fixture base 221, a base 222, and a support seat 223. The fixture base 221 is disposed on the sliding assembly 21. The base 222 is detachably disposed on the fixture base 221. The support seat 223 is detachably disposed on the base 222, and a contour block 2231 is disposed on the support seat 223. The contour block 2231 is used to support and position the small part 2002. The workpiece is placed on the support seat 223 and covers the small part 2002. The lifting mechanism 40 includes a lifting drive 41 and a lifting member 42 connected to the lifting drive 41. The lifting drive 41 is disposed below the sliding assembly 21, and the lifting member 42 is disposed on one side of the sliding assembly 21. The jig base 221 has a lifting clearance hole 221a so that the lifting member 42 passes through the lifting clearance hole 221a and abuts against the base 222 under the drive of the lifting drive member 41, and lifts the base 222 and the support seat 223. Thus, by setting the fixture base 221 on the sliding component 21, the fixture component 22 can move with the sliding component 21, facilitating the placement of the small part 2002 and the workpiece on the fixture component 22; by detachably setting the base 222 on the fixture base 221, the lifting drive component 41 can drive the lifting component 42 through the lifting clearance hole 221a and abut against the base 222, causing the base 222 and the carrier 223 to move closer to the flipping mechanism 50, thereby separating the base 222 and the carrier 223 from the fixture component 22, thus reducing the lifting load of the lifting mechanism 40; by detachably setting the carrier 223 on the base 222, the flipping mechanism 50 can receive the carrier 223 and flip the carrier 223, thereby reducing the flipping load of the flipping mechanism 50, and the locking mechanism 60 only needs to pass through the carrier 223 to lock the small part 2002 and the workpiece, which is beneficial to shortening the length of the locking mechanism 60.

[0161] In some embodiments, the jacking drive 41 can be a linear cylinder, the number of jacking members 42 is two, the two jacking members 42 are spaced apart and connected with the jacking drive 41 through a connecting plate (not shown) which is located below the sliding assembly 21 or the locking platform 70, and the two jacking members 42 are respectively located at two sides of the sliding assembly 21. In this way, by arranging two jacking members 42, the jacking mechanism 40 can keep the base 222 and the bearing seat 223 in a balanced state when jacking the base 222 and the bearing seat 223, and facilitate the turnover mechanism 50 to accurately receive the bearing seat 223.

[0162] In the embodiments of the present application, please refer to Figure 8 and Figure 9 The bearing seat 223 comprises a bearing plate 2232 and a floating plate 2233, the bearing plate 2232 is connected with the floating plate 2233 in a floating manner and faces the turnover mechanism 50, the bearing plate 2232 is provided with a receiving hole 2232a for accommodating a profiling block 2231, the profiling block 2231 is fixedly arranged in the receiving hole 2232a and elastically connected with the floating plate 2233 through a spring, rubber or other elastic object. As Figure 9The profiled block 2231 is stepped, and the accommodating hole 2232a of the bearing plate 2232 is also stepped, so that the profiled block 2231 cooperates with the accommodating hole 2232a to prevent the profiled block 2231 from being separated from the bearing plate 2232 under the elastic force of the elastic object, and the floating connection between the bearing plate 2232 and the floating plate 2233 is achieved through the elastic connection of the profiled block 2231 and the floating plate 2233. The locking hole 2231a is formed in the profiled block 2231 for the locking mechanism 60 to pass through to lock the small piece 2002 on the workpiece. The base 222 includes a guide plate 2221, a mounting plate 2222, a floating pin 2223, and an elastic member 2224. The guide plate 2221 is connected with the mounting plate 2222 and located between the mounting plate 2222 and the floating plate 2233. One end of the floating pin 2223 abuts against the mounting plate 2222 through the elastic member 2224 and is stopped on the guide plate 2221. The other end of the floating pin 2223 movably passes through the locking hole 2231a of the guide plate 2221, the floating plate 2233, the bearing plate 2232, and the profiled block 2231 and protrudes from the profiled block 2231. The other end of the floating pin 2223 is used for positioning the small piece 2002 and the workpiece. In this way, when the adjusting assembly 15 places the small piece 2002 on the bearing plate 2232, the other end of the floating pin 2223 protruding from the profiled block 2231 positions the small piece 2002 and the workpiece, so that the small piece 2002 and the workpiece can be accurately placed on the bearing plate 2232. After the bearing seat 223 is received by the overturning mechanism 50, the overturning mechanism 50 abuts against the floating pin 2223, so that the floating pin 2223 compresses the elastic member 2224, thereby enabling the overturning mechanism 50 to press the workpiece and the small piece 2002 tightly on the bearing plate 2232. In addition, after the base 222 is separated from the bearing plate 2232, the floating pin 2223 is separated from the bearing seat 223 with the base 222, so that the locking hole 2231a is exposed, facilitating the locking mechanism 60 to pass through the locking hole 2231a to lock the small piece 2002 and the workpiece. When the small piece 2002 and the workpiece are locked, because the floating pin 2223 is elastically connected with the mounting plate 2222, when the bearing seat 223 is connected with the base 222, the floating pin 2223 passes through the locking hole 2231a and abuts against the assembled small piece 2002 and workpiece. The floating pin 2223 compresses the elastic member 2224 under the action of the assembled small piece 2002 and workpiece, thereby avoiding the assembled small piece 2002 and workpiece from being pushed out of the bearing plate 2232.

[0163] In the embodiments of the present application, in order to further accurately position the workpiece, and at the same time enable the workpiece to be clamped on the bearing seat 223, the bearing plate 2232 of the bearing seat 223 is further provided with a first positioning member 2234 and a second positioning member 2235. The number of the first positioning member 2234 and the second positioning member 2235 is multiple, multiple first positioning members 2234 are arranged on the bearing plate 2232 according to the structure of the workpiece, and the multiple first positioning members 2234 position the workpiece in the first direction. Multiple second positioning members 2235 are arranged on the bearing plate 2232 along the contour of the workpiece, and are used to position the workpiece in the second direction and the third direction. It can also be understood that the multiple second positioning members 2235 are used to clamp or support the workpiece, so that the workpiece can be fixed on the bearing plate 2232, and the small part 2002 and the workpiece after assembly are prevented from being pushed out of the bearing plate 2232 by the floating pin 2223. In this way, by arranging the first positioning member 2234 and the second positioning member 2235, the workpiece can be further accurately positioned, and the assembly yield of the small part 2002 and the workpiece is improved. In addition, it can also prevent the small part 2002 and the workpiece after assembly from being pushed out of the bearing plate 2232 by the floating pin 2223.

[0164] In the embodiments of the present application, in order to facilitate the accurate placement of the bearing seat 223 on the base 222 again, multiple guide grooves 2233a are formed on the side of the floating plate 2233 facing the guide plate 2221, and multiple guide rods 224 are arranged on the side of the guide plate 2221 facing the floating plate 2233. The guide plate 2221 guides and positions the floating plate 2233 through the cooperation of the guide rods 224 and the guide grooves 2233a. In this way, by arranging the matching guide grooves 2233a and guide rods 224, the bearing seat 223 can be accurately placed on the base 222 again after the bearing seat 223 leaves the base 222, and the bearing seat 223 is prevented from being placed on the base 222 again due to a large deviation, which is not conducive to placing the small part 2002 and the workpiece on the bearing seat 223. It can be understood that the guide grooves and guide rods can also be arranged on the base 222 and the jig base 221 to ensure that the base 222 can be accurately placed on the jig base 221 again.

In this way, the turnover mechanism 50 realizes the fixation and turnover of the carrier 223. The turnover mechanism 50 can further comprise a bearing seat, a bearing and the like structure to realize the connection between the turnover driving piece 54 and the cover plate 51. The protruding piece 2236 can be arranged in the following way: one end of the protruding piece 2236 which is away from the turnover mechanism 50 passes through the carrier plate 2232 and protrudes from the carrier plate 2232, and is connected with the floating plate 2233, so that the protruding piece 2236 is connected with the carrier 223. In this way, the turnover mechanism 50 can receive and fix the carrier 223 through the cooperation between the bolt 53 and the protruding piece 2236. Alternatively, one end of the protruding piece 2236 which is away from the turnover mechanism 50 passes through the carrier plate 2232 and the floating plate 2233 and protrudes from the floating plate 2233, and is connected with the other end of the protruding piece 2236 through a screw, so that the protruding piece 2236 is connected with the carrier 223.

[0166] In some embodiments, after the turnover mechanism 50 receives the carrier 223, the carrier 223 is turned over, so that the small items are above the products. In the illustrated embodiment, the turnover angle of the turnover mechanism 50 is 180 degrees, i.e. the carrier 223 and the small items and products thereon are turned over by 180 degrees, so that the small items, the products and the carrier 223 are above the turnover mechanism 50, and the carrier 223, the small items, the products and the turnover mechanism 50 are arranged in sequence from top to bottom, so as to enable the locking mechanism 60 above the turnover mechanism 50 to lock the small items and the products. In other embodiments, the turnover angle of the turnover mechanism 50 can also be determined according to the position of the turnover mechanism relative to the locking mechanism 60, as long as the products and the small items after the turnover of the turnover mechanism 50 are opposite to the locking mechanism 60.

[0167] In the embodiments of the present application, the number of the protruding pieces 2236 is four, the number of the latches 53 is two and the shape of the latches 53 is concave, and the latch driving member 52 is a double-headed linear cylinder, so that each output end of the double-headed linear cylinder is connected with one latch 53, and each latch 53 corresponds to two protruding pieces 2236. In the illustrated embodiments, the protruding pieces 2236 are T-shaped, and the T-shaped protruding pieces 2236 have a certain gap with the side of the cover plate 51 away from the jacking mechanism 40 after passing through the protruding avoiding holes 511, and the latches 53 can make the cover plate 51 receive and fix the carrier seat 223 or loosen the carrier seat 223 by inserting or withdrawing the gap. The working process of the turnover mechanism 50 is as follows: the jacking driving member 41 drives the jacking piece 42 to pass through the jacking avoiding hole 221a to jack up the base 222 and the carrier seat 223 to move close to the turnover mechanism 50, the protruding pieces 2236 on the carrier seat 223 pass through the protruding avoiding holes 511 adaptively, the latch driving member 52 drives the latches 53 to slide to cooperate with the corresponding protruding pieces 2236, so as to fix the carrier seat 223 on the cover plate 51; at the same time, in the process that the carrier plate 2232 moves close to the cover plate 51, the cover plate 51 abuts against the floating pin 2223, so that the floating pin 2223 moves downward to compress the elastic member 2224, until the cover plate 51 contacts the workpiece and presses the workpiece and the small piece 2002 on the carrier plate 2232; the jacking driving member 41 drives the jacking piece 42 to drive the base 222 to move away from the carrier seat 223, so that the base 222 is separated from the carrier seat 223 to avoid interference with the cover plate 51 and the carrier seat 223 when the turnover driving member 54 turns over the cover plate 51 and the carrier seat 223; the turnover driving member 54 drives the cover plate 51 and the carrier seat 223 to turn over, so that the small piece 2002 is located above the workpiece. The locking mechanism 60 passes through the floating plate 2233 and the locking hole 2231a to lock the small piece 2002 on the workpiece by means of a screw, so as to complete the turnover and locking of the small piece 2002 and the workpiece. After the locking is completed, the turnover driving member 54 drives the cover plate 51 and the carrier seat 223 to turn over, the jacking driving member 41 drives the jacking piece 42 to drive the base 222 to move close to the carrier seat 223, until the base 222 abuts against the carrier seat 223, the latch driving member 52 drives the latches 53 to move away from the corresponding protruding pieces 2236, so that the cover plate 51 loosens the carrier seat 223, the jacking driving member 41 drives the jacking piece 42 to drive the base 222 and the carrier seat 223 to move away from the cover plate 51, until the base 222 and the carrier seat 223 are placed on the jig base 221.

[0168] In some embodiments, the latch 53 and the protruding piece 2236 can be a bevel matching, a concave-convex matching or other matching. For example, a groove is formed on the protruding piece 2236, and one end of the latch 53 is provided as a protrusion matched with the groove, and the fixing between the cover plate 51 and the bearing plate 2232 is achieved by inserting the protrusion into the groove. For example, one end of the protruding piece 2236 is provided as a T-shaped, and one end of the latch 53 is provided as a bevel, and the fixing between the cover plate 51 and the bearing plate 2232 is achieved by inserting the latch 53 into the right angle of the T-shaped protruding piece 2236.

The workpiece sensor 225 is used to sense the workpiece to determine that the workpiece is placed on the bearing seat 223. For example, when the workpiece sensor 225 generates a signal, it indicates that the workpiece has been placed on the bearing plate 2232, otherwise, the workpiece is not placed on the bearing plate 2232. In this way, it can be ensured that the base 222 is placed on the jig base 221, the bearing seat 223 is placed on the base 222, and the workpiece is placed on the bearing seat 223.
