Description

Technical Field

[0001] This invention relates to the field of automated assembly technology, and more particularly to assembly apparatus. Background Technology

[0002] A thermal relay is a relay that activates when the ambient temperature reaches a given value. Its principle involves firmly bonding two metals or alloys with significantly different coefficients of thermal expansion together to form a disc-shaped bimetallic strip. When the temperature rises to a certain value, the bimetallic strip bends upwards due to the greater expansion of the lower metal layer and the smaller expansion of the upper metal layer. This bending, when it reaches a certain point, actuates the electrical contacts, thus connecting or disconnecting the load circuit. When the temperature drops to a certain value, the bimetallic strip gradually returns to its original shape, and when it returns to a certain point, it reverses the action, actuating the electrical contacts to disconnect or connect the load circuit. The thermal relay's internal components are mounted on a base, and then a housing is installed to protect these internal components.

[0003] Currently, the assembly of the upper cover and transparent sheet on the thermal relay production line is done manually, which is labor-intensive and prone to incomplete assembly, making it impossible to guarantee product assembly consistency. Summary of the Invention

"Below," "below," and "under" the first feature in relation to the second feature includes the first feature directly below and diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0064] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0065] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0066] A thermal relay mounts its internal components on a base, which is then covered to protect the internal components. To facilitate observation of the components inside the cover, an opening is provided in the cover, through which a transparent sheet is installed. This provides both convenient observation and protection.

[0067] Currently, the assembly of the upper cover and transparent sheet on the thermal relay production line is done manually, which is labor-intensive and prone to incomplete assembly, making it impossible to guarantee product assembly consistency.

[0068] like Figures 1-13 As shown, this embodiment provides an assembly device to solve the above-mentioned problems. The assembly device includes a support 1 and an upper cover transmission mechanism 2, a transparent sheet transmission mechanism 3, a thermal relay body transmission mechanism 4, an assembly mechanism 5, and a transport mechanism 6 disposed on the support 1.

[0069] The upper cover transmission mechanism 2 is provided with a stop position 221, which is used to transmit the upper cover 100 to the stop position 221.

[0070] The assembly mechanism 5 is provided with a first station 512 and a second station 513. The transparent sheet transfer mechanism 3 is used to transfer the transparent sheet 200 to the first station 512. The transport mechanism 6 transports the upper cover 100 at the stopping position 221 to the second station 513. The assembly mechanism 5 is used to assemble the transparent sheet 200 on the first station 512 to the mounting port 101 of the upper cover 100 on the second station 513.

[0071] The thermal relay body transmission mechanism 4 is provided with an assembly position 41. The transport mechanism 6 assembles the upper cover 100, on which the transparent sheet 200 is mounted on the second station 513, to the thermal relay body 300 at the assembly position 41.

[0072] When the device is working, the upper cover transfer mechanism 2 first transfers the upper cover 100 without the transparent sheet 200 to the stopping position 221. At this time, the conveying mechanism 6 moves the upper cover 100 from the stopping position 221 to the second station 513. The transparent sheet transfer mechanism 3 transfers the transparent sheet 200 to the first station 512. The assembly mechanism 5 installs the transparent sheet 200 at the first station 512 onto the mounting port 101 of the upper cover 100 at the second station 513. Then, the conveying mechanism 6 assembles the upper cover 100 with the transparent sheet 200 installed at the second station 513 onto the thermal relay body 300, thus completing the assembly of the thermal relay. This process is completed entirely by the assembly device, thereby solving the problems of high labor intensity and incomplete installation of the upper cover 100 and transparent sheet 200 due to manual assembly, and the inability to guarantee product assembly consistency.

[0073] The structure and function of assembly mechanism 5 are described below, such as... Figure 2 and 3 As shown.

[0074] Optionally, the assembly mechanism 5 includes an assembly body 51, a clamping assembly, and an assembly assembly 53. The first station 512 and the second station 513 are respectively located on opposite sides of the assembly body 51. The clamping assembly is configured to press the upper cover 100 against the assembly body 51. The assembly body 51 is provided with a sliding hole 511. When the upper cover 100 is located at the second station 513, the mounting opening 101 is opposite to one end of the sliding hole 511, and the first station 512 is opposite to the other end of the sliding hole 511. The assembly assembly 53 is configured to drive the transparent sheet 200 located at the first station 512 to slide through the sliding hole 511 and be assembled onto the upper cover 100. In this embodiment, the shape of the sliding hole 511 is the same as the shape of the transparent sheet 200. Therefore, the transparent sheet 200 can slide in the sliding hole 511. Since the upper cover 100 is pressed to the second station 513 by the pressing component, the sliding hole 511 is opposite to the mounting port 101. Therefore, the assembly component 53 can drive the transparent sheet 200 of the first station 512 to slide through the sliding hole 511 and be assembled at the mounting port 101 of the upper cover 100.

[0075] Optionally, the clamping assembly includes a first driver and a pressure plate. The pressure plate is opposite to the second station 513. The first driver switches the pressure plate between a first state and a second state. The first state is the state where the upper cover 100 at the second station 513 is clamped to the assembly body 51 by the pressure plate; the second state is the state where the pressure plate is separated from the upper cover 100. In this embodiment, in the first state, the first driver drives the pressure plate to move towards the assembly body 51 until the pressure plate clamps the upper cover 100 on the assembly body 51. In the second state, the first driver drives the pressure plate to move away from the upper cover 100 of the assembly body 51 until the pressure plate is no longer opposite to the assembly body 51. When the conveying mechanism 6 conveys the upper cover 100 to or from the second station 513, in order to prevent interference between the pressure plate and the upper cover 100, the pressure plate is not opposite to the upper cover 100 in the second state.

[0076] Further, the pressure plate includes a first pressure plate 527 and a second pressure plate 528, and the first driver includes a first driving member 521, a driving plate 522, a first connecting plate 523, a second connecting plate 524, a first elastic member 525, and an abutment member 526. The first connecting plate 523 and the second connecting plate 524 are spaced apart along the first direction X on both sides of the assembly body 51. One end of the first connecting plate 523 and one end of the second connecting plate 524 are respectively fixed to the first pressure plate 527 and the second pressure plate 528. The other end of the first connecting plate 523 and the other end of the second connecting plate 524 are respectively slidably disposed on the driving plate 522 along the first direction X. The two ends of the member 525 are fixedly connected to the first connecting plate 523 and the second connecting plate 524 respectively. The first connecting plate 523 and the second connecting plate 524 are respectively provided with the first inclined surface 5231 and the second inclined surface 5241. The abutting member 526 is provided on the bracket 1 and abuts against the first inclined surface 5231 and the second inclined surface 5241 respectively. The cooperation structure between the first inclined surface 5231 and the second inclined surface 5241 and the abutting member 526 makes the first pressure plate 527 and the second pressure plate 528 approach each other or move away from each other when the first driving member 521 drives the driving plate 522 to rise or fall along the third direction Z. The first direction X and the third direction Z are perpendicular to each other. In this embodiment, the drive plate 522 is provided with a slide rail along the first direction X. The other end of the first connecting plate 523 and the other end of the second connecting plate 524 are respectively slidably engaged with the slide rail. The first connecting plate 523 and the second connecting plate 524 are respectively provided with a first inclined surface 5231 and a second inclined surface 5241. The first inclined surface 5231 and the second inclined surface 5241 are opposite to each other and move closer to the assembly body 51 along the third direction Z. The distance between the first inclined surface 5231 and the second inclined surface 5241 gradually increases. The abutting member 526 is disposed between the first inclined surface 5231 and the second inclined surface 5241 and abuts against the first inclined surface 5231 and the second inclined surface 5241 at the same time.

[0077] When the first driving member 521 drives the driving plate 522 to move closer to the assembly body 51 along the third direction Z, the abutting member 526 acts on the first inclined surface 5231 and the second inclined surface 5241, thereby causing the first connecting plate 523 and the second connecting plate 524 to move away from each other. At this time, the first pressure plate 527 and the second pressure plate 528 move away from the upper cover 100. At the same time, the distance between the first pressure plate 527 and the second pressure plate 528 gradually increases until the first pressure plate 527 and the second pressure plate 528 are no longer opposite to the upper cover 100. At this time, the pressure plate is in the second state.

[0078] When the first driving member 521 drives the driving plate 522 to move away from the assembly body 51 in the Z direction, the abutment member 526 slides relative to the first inclined surface 5231 and the second inclined surface 5241 respectively. Consequently, the first connecting plate 523 and the second connecting plate 524 move closer to each other under the action of the first elastic member 525. At this time, the first pressure plate 527 and the second pressure plate 528 move closer to the upper cover 100. Simultaneously, the distance between the first pressure plate 527 and the second pressure plate 528 gradually decreases until the first pressure plate 527 and the second pressure plate 528 simultaneously press the upper cover 100 against the assembly body 51. At this point, the pressure plate is in the first state. Specifically, the first driving member 521 can be, for example, a telescopic cylinder.

[0079] Optionally, the assembly component 53 includes a second driving member 531 and a push rod assembly 532. The push rod assembly 532 is opposite to the first station 512. The second driving member 531 is fixed to the bracket 1. The second driving member 531 drives the push rod assembly 532 to slide along the axial direction of the sliding hole 511. The push rod assembly 532 drives the transparent sheet 200 to slide through the sliding hole 511 and be assembled to the upper cover 100. In this embodiment, the push rod assembly 532 includes a push rod, a sliding groove seat, and a floating joint. The sliding groove seat is fixed to the bracket 1. The push rod is slidably engaged with the sliding groove seat. One end of the push rod is fixed with a floating joint. The other end of the push rod is opposite to the sliding hole 511. The driving end of the second driving member 531 is detachably connected to the floating joint. The second driving member 531 drives the push rod to slide relative to the sliding groove seat. Thus, the push rod can slide the transparent sheet 200 located at the first station 512 through the sliding hole 511 to the first station 512 and assemble it with the upper cover 100.

[0080] Optionally, the second drive component 531 can be, for example, an adjustable stroke cylinder, which can be adjusted in height according to the assembly requirements of the transparent sheet 200 and the upper cover 100 to ensure structural compatibility.

[0081] The structure and function of the transparent sheet transmission mechanism 3 are described below, such as... Figure 4 and 5 As shown.

[0082] Optionally, the transparent sheet transfer mechanism 3 includes a sliding bracket 31, a transfer component 8, and multiple carriers 34. The sliding bracket 31 is recessed with an annular groove. The transfer component 8 drives the multiple carriers 34 to move in an arrangement within the annular groove. The first station 512 is opposite to the annular groove. The carriers 34 are provided with receiving through holes 342 for accommodating the transparent sheet 200. The transparent sheet 200 is disposed within the receiving through holes 342. The push rod assembly 532 passes sequentially through the annular groove, the receiving through holes 342, and the sliding hole 511, and assembles the transparent sheet 200 located within the receiving through holes 342 onto the upper cover 100. In this embodiment, the carrier 34 is provided with a receiving through hole 342 for accommodating the transparent sheet 200. The transfer component 8 drives the carrier 34 to slide within the annular groove, thereby delivering the transparent sheet 200 to the first station 512.

[0083] Optionally, the annular chute includes a first chute 311 and a second chute 312. The first end of the first chute 311 and the first end of the second chute 312 are connected, and the second end of the first chute 311 and the second end of the second chute 312 are connected. The first end of the second chute 312 is provided with a loading position 3122, and the second end of the second chute 312 is provided with a discharging position 3121. The transmission component 8 includes a first transmission component 32, which includes a conveyor belt 321 and a second driver 322. The conveyor belt 321 is laid on the first chute 311, and the second driver 322 drives the conveyor belt 321 to rotate and make the conveyor belt 321 located on the first chute 311 rotate. The carrier 34 in the groove 311 slides from the first end of the first chute 311 to the second end; the transmission assembly 8 also includes a second transmission assembly 33, which includes a third drive member 331, a fourth drive member 332 and a fifth drive member 333. The third drive member 331 drives the carrier 34 located at the second end of the first chute 311 to slide to the loading position 3122. The fourth drive member 332 drives the carrier 34 located at the loading position 3122 to slide from the second end of the second chute 312 to the first end to the unloading position 3121. The fifth drive member 333 drives the carrier 34 located at the unloading position 3121 to slide into the first chute 311. In this embodiment, the first slide 311 and the second slide 312 are two straight slides that fit together. The first end of the first slide 311 and the first end of the second slide 312 are connected, and the second end of the first slide 311 and the second end of the second slide 312 are also connected. The conveyor belt 321 is disposed in the first slide 311, and the conveyor belt 321 drives the carrier 34 to slide from the first end of the first slide 311 to the second end. When the carrier 34 slides to the second end of the first slide 311, the third drive member 33... 1. The drive carrier 34 slides from the first chute 311 to the loading position 3122 at the second end of the second chute 312. At this time, from the second end of the second chute 312 to the first end of the second chute 312, the fourth drive member 332 drives the carrier 34 at the loading position 3122 to move out of the loading position 3122, thereby facilitating the movement of the carrier 34 in the first chute 311 to the loading position 3122. At this time, the carrier 34 that has moved out of the loading position 3122 pushes the carriers 34 in front of it to move in an orderly manner. In this cycle, the carriers 34 in the second chute 312 gradually move from the second end of the second chute 312 to the first end of the second chute 312. When the carrier 34 in the second chute 312 moves to the unloading position 3121 at the first end of the second chute 312, the fifth drive member 333 drives the carrier 34 located at the unloading position 3121 to slide onto the conveyor belt 321 of the first chute 311. Specifically, the third drive component 331, the fourth drive component 332, and the fifth drive component 333 can all be telescopic cylinders as power components.

[0084] The structure and function of the transparent sheet feeding mechanism are described below, such as... Figure 9 As shown.

[0085] Optionally, the assembly apparatus further includes a transparent sheet feeding mechanism, which includes a robotic arm 71 and a feeder 72. The robotic arm 71 is configured to move the transparent sheet 200 in the feeder 72 to the receiving through hole 342 of the carrier 34 located in the second chute 312. In this embodiment, multiple carriers 34 slide in an annular chute. To ensure that the receiving through hole 342 of each carrier 34 reaching the first station 512 contains a transparent sheet 200, the robotic arm 71 continuously moves the transparent sheet 200 in the feeder 72 to the receiving through hole 342 of the carrier 34 located in the second chute 312.

[0086] Optionally, the transparent sheet feeding mechanism further includes a feeding plate 74 and a positioning component 75. The feeding plate 74 is fixed to the sliding bracket 31 and has a feeding hole 741. When the carrier 34 slides between the feeding plate 74 and the sliding bracket 31, the positioning component 75 is used to align the receiving through hole 342 of the carrier 34 located between the feeding plate 74 and the sliding bracket 31 with the feeding hole 741. The robotic arm 71 moves the transparent sheet 200 into the feeding hole 741 and it falls into the receiving through hole 342. In this embodiment, the cross-sectional area of ​​the feeding hole 741 perpendicular to the axis gradually increases from the direction close to the receiving through hole 342 to the direction away from the receiving through hole 342. Therefore, when the robotic arm 71 feeds the transparent sheet 200 into the feeding hole 741, the transparent sheet 200 can slide into the receiving through hole 342 by its own gravity.

[0087] Optionally, the feeding plate 74 is provided with a plurality of feeding holes 741 at intervals along the sliding direction of the second slide groove 312, the positioning assembly 75 includes a seventh driving member 751 and a positioning plate 752, the carrier 34 is provided with a positioning groove 341, and the positioning plate 752 is provided with a plurality of positioning blocks 753 at intervals. When the plurality of carriers 34 slide between the feeding plate 74 and the sliding bracket 31, the seventh driving member 751 drives the positioning plate 752 to move and causes the plurality of positioning blocks 753 to be inserted into or disengaged from the positioning grooves 341 of the plurality of carriers 34 in a one-to-one correspondence.

[0088] In this embodiment, the side wall of the carrier 34 is provided with a V-shaped positioning groove 341, and a plurality of V-shaped positioning blocks 753 are spaced apart on the positioning plate 752. The seventh driving member 751 drives the positioning plate 752 to move towards the carrier 34 in the second slide groove 312, so that the plurality of positioning blocks 753 are inserted one-to-one into the positioning grooves 341 of the plurality of carriers 34. During the process of the positioning blocks 753 being inserted into the positioning grooves 341, the positioning blocks 753 will adjust the position of the carrier 34. When the positioning blocks 753 are fully inserted into the positioning grooves 341, the receiving through holes 342 of the plurality of carriers 34 correspond one-to-one with the plurality of feeding holes 741 and are opposite each other. At this time, the seventh driving member 751 drives the positioning plate 752 to move away from the second slide groove 312. Specifically, the seventh driving member 751 can be, for example, a telescopic cylinder.

[0089] Optionally, the transparent sheet transmission mechanism 3 further includes a position adjustment component 35, which includes a sixth driving member 351 and an adjusting rod 352. When the receiving through hole 342 is opposite to the adjusting rod 352, the sixth driving member 351 drives the adjusting rod 352 to have two positions: extending into the receiving through hole 342 and disengaging from the receiving through hole 342. In this embodiment, when the transparent sheet 200 is placed in the receiving through hole 342, the axis of the transparent sheet 200 and the receiving through hole 342 may not be perpendicular. Consequently, the push rod cannot accurately assemble the transparent sheet 200 to the mounting opening 101 of the upper cover 100. To prevent this from happening, the sixth driving member 351 drives the adjusting rod 352 to extend into the receiving through hole 342, thereby making the axis of the transparent sheet 200 perpendicular to the receiving through hole 342.

[0090] Optionally, the feeder 72 includes a storage hopper 721 and a screening tray 722. The storage hopper 721 provides transparent sheets 200 to the screening tray 722, and the screening tray 722 adjusts the position of the transparent sheets 200 within the screening tray 722 by vibration. In this embodiment, the transparent sheets 200 are screened (discretely or uniformly) by the vibration of the screening tray 722, thereby adjusting the position of the transparent sheets 200 within the screening tray 722, which facilitates the handling by the robotic arm 71.

[0091] Optionally, the transparent sheet feeding mechanism further includes a vision recognition component 73, which is fixed to the robotic arm 71. In this embodiment, the vision recognition component 73 includes a vision camera and a position adjustment component. The position adjustment component positions the vision camera on the robotic arm 71, and the position of the vision camera relative to the robotic arm 71 can be adjusted by the position adjustment component.

[0092] The structure and function of the conveying mechanism 6 are described below, such as... Figure 10 and 11 As shown.

[0093] Optionally, the conveying mechanism 6 includes a sliding component 61, a first conveying component 62, and a second conveying component 63. Both the first and second conveying components 62 and 63 are disposed on the sliding component 61. The sliding component 61 switches between a first position and a second position. When the sliding component 61 is in the first position, the first conveying component 62 is opposite to the stopping position 221, and the second conveying component 63 is opposite to the second workstation 513. When the sliding component 61 is in the second position, the first conveying component 62 is opposite to the second workstation 513, and the second conveying component 63 is opposite to the assembly position 41. In this embodiment, to improve assembly efficiency, both the first and second conveying components 62 and 63 are disposed on the sliding component 61, thereby driving the first and second conveying components 62 and 63 to move synchronously. When the sliding component 61 is in the first position, the first transport component 62 picks up the upper cover 100 without the transparent sheet 200 on the stopping position 221, and at the same time, the second transport component 63 picks up the upper cover 100 with the transparent sheet 200 on the second station 513; when in the second position, the first transport component 62 is opposite to the second station 513 and places the upper cover 100 without the transparent sheet 200 on the second station 513, and the second transport component 63 is opposite to the assembly position 41 and assembles the upper cover 100 with the transparent sheet 200 onto the thermal relay body 300.

[0094] Optionally, the stopping position 221, the second working position 513, and the assembly position 41 are arranged along the first direction X; the sliding component 61 includes a first sliding part 611, a second sliding part 612, and a sliding plate 613. The first sliding part 611 drives the second sliding part 612 to slide along the first direction X, and the second sliding part 612 drives the sliding plate 613 to slide along the second direction Y. The first transport component 62 and the second transport component 63 are both disposed on the sliding plate 613, and the first direction X and the second direction Y are perpendicular to each other. In this embodiment, the first sliding part 611 and the second sliding part 612 are both telescopic cylinders. The first slide groove 311 and the second slide groove 312 of the transparent sheet transport mechanism 3 are arranged along the third direction Z, and the thermal relay body transport mechanism 4 is a fork shifting mechanism, which causes the thermal relay body 300 to be transported along the third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0095] Optionally, the first conveying assembly 62 includes a first gripper cylinder 621, a first gripper, a motor 622, and an angle adjusting component 623. The motor 622 is mounted on the sliding assembly 61, and the shaft of the motor 622 is fixedly connected to the first gripper cylinder 621. The first gripper is mounted on the first gripper cylinder 621. The angle adjusting component 623 is used to detect the rotation angle of the motor 622. In this embodiment, when the angle of the upper cover 100 at the stopping position 221 is inconsistent with the angle of the upper cover 100 at the second work station 513, the angle adjusting component 623 needs to adjust the angle of the upper cover 100 through the motor 622. In this embodiment, the angle of the upper cover 100 at the stopping position 221 differs from the angle of the upper cover 100 at the second work station 513 by 90 degrees. Therefore, the angle adjusting component 623 detects the rotation angle of the motor 622 and thus rotates the upper cover 100 by 90 degrees.

[0096] Optionally, the angle adjustment component 623 includes a photoelectric switch receiver, a photoelectric switch transmitter, and a light-shielding ring. The light-shielding ring is sleeved on and fixedly connected to the rotating shaft. A notch is formed in the radial direction of the light-shielding ring. The photoelectric switch receiver and the photoelectric switch transmitter are located on opposite sides of the light-shielding ring and are both fixedly connected to the sliding assembly 61. In this embodiment, when the light signal emitted by the photoelectric switch transmitter passes through the notch and is received by the photoelectric switch receiver, the motor 622 is in the starting state, thereby driving the upper cover 100 to rotate. When the light signal emitted by the photoelectric switch transmitter is blocked by the light-shielding ring, the motor 622 stops working.

[0097] Optionally, the second conveying assembly 63 includes a fixed base 631, a sliding base 632, a second elastic element 633, a second gripper, and a second gripper cylinder 634. The fixed base 631 is fixed to the sliding assembly 61, the sliding base 632 is slidably disposed on the sliding assembly 61, the second elastic element 633 is disposed between the fixed base 631 and the sliding base 632 and abuts against both the fixed base 631 and the sliding base 632 respectively, the second gripper cylinder 634 is fixedly connected to the sliding base 632, and the second gripper is disposed on the second gripper cylinder 634. In this embodiment, the second elastic element 633 is a spring, which can play a buffering role, thereby preventing the second gripper cylinder 634 from damaging the upper cover 100 or the thermal relay body 300 when installing the upper cover 100 onto the thermal relay body 300.

[0098] Optionally, the second conveying assembly 63 further includes a first adjusting seat 635, a first adjusting bolt, a second adjusting seat 636, a second adjusting bolt, and a stop block 637. The first adjusting seat 635 and the second adjusting seat 636 are fixedly spaced on the slide plate 613 along the sliding direction of the sliding seat 632. The stop block 637 is fixed on the sliding seat 632 and located between the first adjusting seat 635 and the second adjusting seat 636. The first adjusting seat 635 and the second adjusting seat 636 are respectively provided with threaded holes along the sliding direction of the sliding seat 632. The first adjusting bolt and the second adjusting bolt are respectively screwed to the first adjusting seat 635 and the second adjusting seat 636. The first adjusting bolt and the second adjusting bolt can contact the stop block 637 respectively. In this embodiment, by adjusting the position of the first adjusting bolt relative to the first adjusting seat 635 and the position of the second adjusting bolt relative to the second adjusting seat 636, the distance between the first and second adjusting bolts can be adjusted. Since the stop block 637 is located between the first and second adjusting bolts, adjusting the distance between the first and second adjusting bolts can adjust the upper and lower limits of the sliding seat 632, improving the compatibility of the second conveying assembly 63 and avoiding difficulties in operation and adjustment caused by processing or assembly errors. In other embodiments, the first and second adjusting bolts can be replaced by a first adjusting cylinder and a second adjusting cylinder. The first adjusting cylinder is fixed to the first adjusting seat 635, and the second adjusting bolt is fixed to the second adjusting seat 636. By adjusting the extension and retraction of the first and second adjusting cylinders, the range of motion of the stop block 637 can be limited.

[0100] Optionally, the upper cover conveying mechanism 2 includes an upper cover conveying component 21 and a misalignment component 22. The misalignment component 22 includes a misalignment carrier and an eighth driving member. A stopping position 221 is disposed on the misalignment carrier. The discharge port of the upper cover conveying component 21 is opposite to the misalignment carrier and conveys the upper cover 100 to the stopping position 221. The eighth driving member drives the misalignment carrier to slide in a direction perpendicular to the discharge port. In this embodiment, the upper cover conveying component 21 is, for example, a direct vibration feeding component, which conveys the upper cover 100 through vibration. When the upper cover conveying component 21 conveys one upper cover 100 to the stopping position 221, in order to prevent other upper covers 100 from being conveyed to the stopping position 221, the eighth driving member drives the misalignment carrier to misalign the output port of the upper cover conveying component 21 with the stopping position 221.
