Description

Technical Field

[0001] This invention relates to the technical field of time switch manufacturing, and more specifically to an automatic assembly equipment for time switches. Background Technology

[0002] A time-controlled switch is a power switch control device composed of a single-chip microprocessor as its core and electronic circuits. It can control the opening and closing of home appliances in a daily or weekly cycle and at multiple time periods. It is suitable for the automatic control of various industrial and household electrical appliances, and is safe, convenient, energy-saving and cost-effective.

[0003] like Figure 1 As shown, the time control switch includes a housing, a positive conductive plate, a negative conductive plate, and a light guide post. The housing has a battery slot and a locking hole for the light guide post. Currently, the assembly process of the time control switch is mainly manual, where the positive and negative conductive plates are inserted into the two ends of the battery slot, and then the light guide post is placed in the locking hole. The assembly equipment is then manually operated to press the light guide post into the locking hole. The current assembly process of the time control switch relies mainly on manual labor, resulting in low production efficiency, high labor costs, and even the possibility that tired workers may reverse the positions of the positive and negative conductive plates, affecting the normal use of the circuit. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an automatic assembly equipment for time-controlled switches that can improve processing efficiency, increase processing accuracy, and reduce labor costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic assembly equipment for a time-controlled switch, comprising a workbench, a processing and transport line positioned on the workbench with multiple stations, a conveyor line parallel to the processing and transport line for transporting the housing, a feeding mechanism distributed sequentially along the transport direction of the processing and transport line and corresponding to individual stations of the processing and transport line, a positive electrode assembly mechanism, a negative electrode assembly mechanism, a conductive sheet bending mechanism, a first flipping mechanism, a light guide post installation mechanism, a second flipping mechanism, and a discharging mechanism. The feeding mechanism transports the housing from the conveyor line to the processing and transport line, allowing the housing to complete the installation of the positive electrode conductive sheet, the negative electrode conductive sheet, and the light guide post at different stations in sequence, and finally the discharging mechanism transports the housing to the conveyor line.

[0006] As a further improvement of the present invention, the conductive sheet bending mechanism includes a pressure plate for pressing down the conductive sheet, a pressure cylinder for moving the pressure plate up and down, two bending rods located below the housing, a bending cylinder for moving the two bending rods toward each other, and a bending cylinder for moving the bending cylinder up and down. After the pressure plate presses down the two conductive sheets on the housing into place, the bending cylinder moves the two bending rods toward each other so that the parts of the two conductive sheets that protrude from the housing are bent.

[0007] As a further improvement of the present invention, bending grooves are provided at the ends of the two bending rods near the housing. The two bending grooves are arranged facing each other and the groove height is less than the length of the lower end of the conductive sheet protruding from the housing. After the bending cylinder drives the two bending rods to move into place, the parts of the two conductive sheets protruding from the housing are inclined relative to the horizontal plane and located in the bending grooves. The bending cylinder drives the two bending rods to move upward so that the two bending rods partially extend into the inner cavity of the housing and the parts of the two conductive sheets protruding from the housing are flattened.

[0008] As a further improvement of the present invention, both of the bending rods are provided with a bending surface that can tilt relative to the vertical plane and force the end of the conductive sheet to bend.

[0009] As a further improvement of the present invention, both the positive electrode assembly mechanism and the negative electrode assembly mechanism include a direct vibration conveying channel, a vibratory plate connected to one end of the direct vibration conveying channel, a support block positioned at the other end of the direct vibration conveying channel and used to support the conductive sheet, a gate-shaped limiting member located above the support block, a limiting cylinder for driving the limiting member to move up and down, a first gripper for clamping the conductive sheet, a first drive assembly for driving the first gripper to rotate and translate, a second gripper located above the first gripper and used to clamp the conductive sheet, and a second drive assembly for driving the second gripper to rotate and move. The support block has limiting grooves for inserting both ends of the limiting member and located on both sides of the conductive sheet. By inserting both ends of the limiting member into the corresponding limiting grooves, the conductive sheet is partially obstructed by the limiting member and cannot move. The end of the conductive sheet that extends beyond the end face of the support block can be clamped by the first gripper.

[0010] As a further improvement of the present invention, the light guide column mounting mechanism includes a pressing cylinder positioned above the processing transport line, a fourth driving component that drives the pressing cylinder to move up and down, a column conveying component connected to the fourth driving component and located below the pressing cylinder, a material distribution base positioned on one side of the processing transport line, a material distribution block that can move linearly relative to the material distribution base, a column conveying pipe positioned above the material distribution block, a material distribution cylinder for driving the material distribution block to move, and a light guide column vibrating plate connected to the column conveying pipe. The material distribution base has an opening for the light guide column to pass through. The material discharge hole is connected to the column conveying component via a guide tube. The column conveying component is misaligned with the material discharge hole. The material distribution block has a material distribution hole that can accommodate the light guide column. The column conveying component has a pressure hole that allows the output shaft of the pressing cylinder to enter and a guide hole that conveys the light guide column into the pressure hole. When the material distribution hole contains the light guide column from the column conveying component, the material distribution cylinder drives the material distribution block to move so that the material distribution hole and the material discharge hole are connected. The light guide column passes through the guide tube and the guide hole to reach the pressure hole. The output shaft of the pressing cylinder extends into the pressure hole and presses the light guide column into the housing.

[0011] As a further improvement of the present invention, it also includes two sets of positioning components corresponding to the positive electrode assembly mechanism and the negative electrode assembly mechanism, respectively. Each set of positioning components includes two positioning cylinders positioned on both sides of the processing transport line and a positioning plate positioned on the output shaft of the positioning cylinder. The end of the positioning plate not connected to the positioning cylinder is located above the processing transport line. The surface of the positioning plate facing the processing transport line is provided with a positioning block that matches the battery slot of the housing. The positioning plate has a hole for the conductive sheet to pass through. The hole passes downward through the positioning block. The positioning cylinder drives the positioning plate to move towards the processing transport line so that the positioning block enters the battery slot of the housing.

[0012] As a further improvement of the present invention, the end face edges of the positioning blocks facing the processing and transport line are all chamfered.

[0013] As a further improvement of the present invention, both the first flipping mechanism and the second flipping mechanism include a third gripper, a third drive assembly that can drive the third gripper to rotate and move up and down, a lifting member located below the housing, and a lifting cylinder that is arranged opposite to the third gripper and can drive the lifting member to move up and down. When the third gripper clamps the housing, the third drive assembly and the lifting cylinder together move the housing upward. After the lifting cylinder is reset, the third drive assembly drives the housing to rotate 10°.

[0014] As a further improvement of the present invention, it also includes a vision inspection component located between the light guide post mounting mechanism and the second flipping mechanism, and a sorting lane positioned at the end of the processing transport line.

[0015] The beneficial effects of this invention are as follows: The feeding mechanism moves the housing on the conveyor line to the processing and transport line. The housing passes through the positive electrode assembly mechanism, negative electrode assembly mechanism, conductive sheet bending mechanism, first flipping mechanism, light guide post installation mechanism and second flipping mechanism in sequence along the processing and transport line. Finally, the unloading mechanism moves the assembled housing back to the conveyor line. Compared with the existing technology that uses manual methods, this design can realize the automated installation of the positive and negative electrodes of the battery compartment and the light guide post. It has a high degree of automation, high processing efficiency and high qualification rate of finished housing products, saving labor costs for manufacturers. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0030] Reference Figures 1 to 12 As shown, an automatic assembly equipment for a time-controlled switch in this embodiment includes a workbench 1, a processing and transport line 2, a conveyor line 3, a feeding mechanism 4 distributed along the transport direction of the processing and transport line 2 and corresponding to individual workstations of the processing and transport line 2, a positive electrode assembly mechanism 5, a negative electrode assembly mechanism 6, a conductive sheet bending mechanism 7, a first flipping mechanism 8, a light guide post mounting mechanism 9, a second flipping mechanism 10, and a discharging mechanism 11.

[0031] The processing and transport line 2 adopts existing technology.

The bearing block 53 has a limiting groove 531 that communicates with the inner cavity of the material channel and is used to support the conductive sheet. The conductive sheet is T-shaped. The maximum width of the limiting groove 531 matches the maximum width of the conductive sheet. The inner cavity width of the limiting member 54 is adapted to the width of the smaller part of the conductive sheet.

The first gripper 56 is located in the length direction of the material channel. The second drive assembly 59 includes a pneumatic gripper with the same pneumatic gripper as the limiting cylinder 55, a rotary cylinder that drives the pneumatic gripper to rotate, a vertical cylinder that drives the rotary cylinder to move up and down, and a horizontal cylinder that drives the vertical cylinder to move along the length direction of the material channel. The second gripper 58 is positioned on the output shaft of the pneumatic gripper and is located above the first gripper 56.

[0034] Both the feeding mechanism 4 and the discharging mechanism 11 have structures similar to those of the second drive assembly 59. Both the feeding mechanism 4 and the discharging mechanism 11 include a horizontal cylinder perpendicular to the transport direction of the processing transport line 2, a vertical cylinder positioned on the output shaft of the horizontal cylinder and perpendicular to the horizontal plane, a pneumatic gripper fixedly connected to the output shaft of the vertical cylinder, and a gripper positioned on the output shaft of the pneumatic gripper.

[0035] The conductive sheet bending mechanism 7 includes a pressure plate 71, a pressure cylinder 72, two bending rods 73, a bending cylinder 74, and a bending cylinder 75. The pressure cylinder 72 and the bending cylinder 75 are both positioned on the same bracket. The pressure cylinder 72 is a linear cylinder, and its output shaft is fixedly connected to one end of the pressure plate 71. The other end of the pressure plate 71 is located above the guide rail. The bending cylinder 75 can be a linear cylinder of model MXS12-30A, and the bending cylinder 74 is a finger cylinder of model MHZ2-32D. The cylinder body is fixedly connected to the output shaft of the bending cylinder 75. One end of each of the two bending rods 73 is positioned on the two output shafts of the bending cylinder 74. Both bending rods 73 are located below the guide rail. Through holes for the bending rods 73 to pass through are opened on the part of the guide rail that supports the end of the housing. There are two conductive sheet bending mechanisms 7, which are located on both sides of the processing transport line 2, so that the conductive sheet can be processed by the corresponding conductive sheet bending mechanism 7 no matter which side of the battery slot of the housing faces the processing transport line 2.

[0036] Both the first flipping mechanism 8 and the second flipping mechanism 10 include a third gripper 81, a third drive assembly 82, a lifting member 83, and a lifting cylinder 84. The third drive assembly 82 includes a rotary swing gripper of model MRHQ16D-180S that is fixedly connected to the third gripper 81 and a linear cylinder for driving the rotary swing gripper to move up and down. The third gripper 81 is located above one of the guide rails and is in a horizontal plane. The lifting cylinder 84 is a linear cylinder located on the other side of the guide rail with its output shaft pointing vertically downward. The lifting member 83 is connected to the output shaft of the lifting cylinder 84 by a connecting plate. The lifting member 83 is located below the guide rail adjacent to the lifting cylinder 84. A through hole is opened on the part of the guide rail that supports one end of the housing for the lifting member 83 to pass through.

[0037] The light guide column mounting mechanism 9 includes a pressing cylinder 91, a fourth drive assembly 92, a column conveying component 93, a material distribution base 94, a material distribution block 95, a column conveying tube 96, a material distribution cylinder 97, and a light guide column vibratory plate 98. The fourth drive assembly 92 includes a bracket located on one side of the processing transport line 2 and fixedly connected to the worktable 1, and a vertical cylinder positioned on the bracket and perpendicular to the horizontal plane. The cylinder body of the pressing cylinder 91 is positioned on the bracket and the output shaft is vertically downward. The pressing cylinder 91 has two output shafts. The column conveying component 93 is located directly below the pressing cylinder 91. The column conveying component 93 has a pressing hole 931 that is adapted to the output shaft of the pressing cylinder 91 and is vertically downward, and a relative length of the pressing hole 931. The guide post hole 932 is inclined and communicates with the pressure hole 931. The material distribution base 94 is positioned on the bracket and has two material dropping holes 941 for the light guide post to pass through. The two material dropping holes 941 are connected to the two guide post holes 932 on the column conveying component 93 through the guide tubes respectively. The material distribution cylinder 97 is a linear cylinder and is fixedly connected to the material distribution base 94. The material distribution base 94 has a material distribution block 95 that is fixedly connected to the output shaft of the material distribution cylinder 97. The material distribution block 95 has two material distribution holes 951 that can accommodate the light guide post. Two column conveying pipes 96, both fixedly connected to the material distribution base 94, are set above the material distribution block 95. Both column conveying pipes 96 can be connected to the light guide post vibrating plate 98 through the guide tubes.

[0038] In the initial state, the two dispensing holes 951 are located directly below the two conveying pipes 96, and the two dispensing holes 951 are offset from the two dropping holes 941. The height of the pressure plate 71 and the third gripper 81 is greater than the height of the guide rail. The first gripper 56 faces the bearing block 53, and both ends of the limiting member 54 are inserted into the limiting groove 531. The assembly steps are as follows.

[0039] Step 1: Place the housing on the conveyor line 3. As the conveyor belt 3 moves to the stop, the housing slides relative to the conveyor line 3. The feeding mechanism 4 transports the housing to the first station of the processing and transportation line 2.

[0040] In the second step, the housing moves along the processing and transport line 2 to the station corresponding to the positive electrode assembly mechanism 5. The vibratory feeder 52 and the direct vibration conveyor 51 successively transport the conductive sheet into the limiting groove 531 of the bearing block 53. The conductive sheet touches the limiting member 54 and stops moving. One end of the conductive sheet extends out of the limiting groove 531 and is located between the two first grippers 56. The first drive component 57 drives the two first grippers 56 to move towards each other and clamp the end of the conductive sheet. Then, the limiting cylinder 55 drives the limiting member 54 to move upward and disengage from the limiting groove 531. The first drive component 57 drives the first gripper 56 to rotate 90° so that the conductive sheet passes through the inner cavity of the limiting member 54 and remains upright and is located below the second gripper 58. Under the drive of the second drive component 59, the second gripper 58 first clamps the conductive sheet. The first gripper 56 releases the conductive sheet and resets with the first drive component 57. Then, the second gripper 58 rotates 90° and partially inserts the conductive sheet into the positive electrode of the battery slot of the housing. Finally, the second gripper 58 resets.

[0041] The third step is to move the housing along the processing and transport line 2 to the station corresponding to the negative electrode assembly mechanism 6, repeat the second step, and complete the installation of the conductive sheet at the negative electrode of the battery slot on the housing.

[0042] Step 4: The housing moves along the processing and transport line 2 to the station corresponding to the conductive sheet bending mechanism 7. The pressing cylinder 72 drives the pressing plate 71 to move downward. The pressing plate 71 that is not corresponding to the battery slot will press the housing and stop moving. The pressing plate 71 corresponding to the battery slot will press the conductive sheets at both ends of the battery slot downward and stop after touching the housing. The ends of the two conductive sheets both protrude from the bottom of the battery slot. The bending cylinder 75 drives the bending cylinder 74 and the bending rod 73 to move upward as a whole into place. The ends of the two conductive sheets are located between the ends of the two bending rods 73. Then the bending cylinder 74 drives the two bending rods 73 to move towards each other. The two bending rods 73 push the ends of the two conductive sheets to bend towards each other. After the conductive sheets are bent into place, the pressing cylinder 72, the bending cylinder 74 and the bending cylinder 75 are all reset.

[0043] In the fifth step, the housing moves along the processing transport line 2 to the station corresponding to the first flipping mechanism 8. Driven by the third drive assembly 82, the third gripper 81 moves downward and clamps the housing. The lifting cylinder 84 drives the lifting component 83 to move upward, so that the lifting component 83 supports one end of the housing. Then, the third gripper 81 and the lifting component 83 together lift the housing upward, so that the housing leaves the station. Then, the lifting component 83 stops moving. The third gripper 81 continues to drive the housing to move upward a certain distance. The housing rotates 180° with the third gripper 81. Finally, the third gripper 81 moves the flipped housing downward. The lifting component 83 supports one end of the housing again and moves downward with the third gripper 81 until the flipped housing returns to the station. The third gripper 81 and the lifting component 83 are both reset.

[0044] Step 6: The housing moves along the processing and transport line 2 to the station corresponding to the light guide post mounting mechanism 9. The light guide post vibratory plate 98 simultaneously transports the two light guide posts to the material distribution block 95. As the fourth drive assembly 92 moves the pressing cylinder 91 and the post conveying component 93 downward as a whole, the ports of the two pressing holes 931 correspond to and are adjacent to the two holes on the housing for installing the light guide posts. The two light guide posts are located in the two material distribution holes 951 respectively. Then, the material distribution cylinder 97 drives the material distribution block 95. The material distribution block 95 moves in a straight line until the material distribution hole 951 corresponds to the material drop hole 941. The material distribution block 95 stops moving, the conveying column tube 96 is misaligned with the material distribution hole 951, and the light guide column in the material distribution hole 951 passes through the material drop hole 941, the guide tube and the lead column hole 932 in sequence and enters the pressing hole 931. The two output shafts of the pressing cylinder 91 enter the two pressing holes 931 respectively and press the two light guide columns into the housing. Then the pressing cylinder 91, the fourth drive component 92 and the material distribution cylinder 97 are all reset.

[0045] Step 7: The housing moves along the processing transport line 2 to the station corresponding to the second flipping mechanism 10, and Step 5 is repeated, the housing is flipped 180°;

[0046] Step 8: The housing moves along the processing and transport line 2 to the station corresponding to the discharge mechanism 11. The discharge mechanism 11 moves the housing containing the conductive sheet and light guide column back to the conveyor line 3 for subsequent collection or entry into the next process.

[0047] Compared with the existing technology that uses manual methods, this design can achieve automated installation of the positive and negative terminals of the battery slot and the light guide column. It has a high degree of automation, high processing efficiency and high qualification rate of the finished shell, saving labor costs for manufacturers. The design of using the lifting component 83 to support one end of the shell can avoid the phenomenon that the shell rotates relative to the third gripper 81 due to gravity when it is held by the third gripper 81, and make up for the defect that the shell is easy to get stuck between the two guide rails and cannot move upward.

[0048] As an improved implementation, the fourth step mentioned in the aforementioned embodiment has a defect. The two bending rods 73 move towards each other, forcing the two conductive sheets to bend. During the bending process, the conductive sheets bend significantly, and the reaction force against the bending rods 73 also increases. The friction between the end of the bending rods 73 and the sidewall of the conductive sheet is high, accelerating the wear of the conductive sheets and affecting the conductivity of subsequent wire connections, thus impacting usability. Furthermore, wear on the bending rods 73 can lead to incomplete bending of the conductive sheets, affecting their structural stability. To solve the aforementioned problems, refer to... Figure 11As shown, each of the two bending rods 73 has a bending groove 76 near its end in the housing. The two bending grooves 76 are arranged facing each other, and the height of the grooves is less than the length of the lower end of the conductive sheet protruding from the housing. The operation in the fourth step mentioned above will change to the following operation: After the housing is pressed down by the pressure plate 71, the bending cylinder 75 drives the bending cylinder 74 and the bending rods 73 to move upward into position as a whole. The ends of the two conductive sheets are located between the ends of the two bending rods 73. Then, the bending cylinder 74 drives the two bending rods 73 to move towards each other. Due to the edge formed by the bending grooves 76, the two bending rods 73 will first push the conductive sheet to bend at a certain angle. After the bent part of the conductive sheet contacts the top of the wall of the bending groove 76, the bending cylinder 75 drives the bending cylinder 74 and the bending rod 73 to continue to move upward as a whole. The bottom of the bending groove 76 pushes the end of the conductive sheet upward until the end of the conductive sheet bends 90° relative to the part of the conductive sheet located in the battery slot. The pressing cylinder 72, the bending cylinder 74 and the bending cylinder 75 are all reset. Compared with the previous embodiment, this design changes the bending step of the conductive sheet from one step to two steps, which greatly reduces the wear between the bending rod 73 and the conductive sheet and indirectly ensures the structural stability of the conductive sheet and the bending rod.

[0049] Further optimization, refer to Figure 11 As shown, both bending rods 73 are provided with bending surfaces 77 that are inclined relative to the vertical plane and force the ends of the conductive sheets to bend. The two bending surfaces 77 are arranged facing each other and connected to the bottom of the bending groove 76. When the housing moves to below the pressure plate 71, the two bending surfaces 77 are located below the two ends of the battery slot of the housing, respectively. The bending cylinder 75 drives the bending cylinder 74 and the bending rods 73 to move upward into position as a whole. Then, the pressure cylinder 72 drives the pressure plate 71 to move downward. The pressure plate 71 presses the two conductive sheets... Both are pushed downwards, and the lower ends of the two conductive sheets pass through the battery slot and slide relative to the bending surface 77, thus bending them. After the pressure plate 71 moves into place, the bending cylinder 74 drives the two bending rods 73 to move towards each other, and the lower end of the conductive sheet is bent into place. Finally, the pressure cylinder 72, bending cylinder 74 and bending cylinder 75 are all reset. Compared with the previous embodiment, this design can perform preliminary bending of the lower end of the conductive sheet while the conductive sheet moves downwards, thus shortening the processing time of the conductive sheet bending step and improving processing efficiency.

[0050] As one specific implementation method of the improvement, refer to Figure 9 and Figure 10As shown, it also includes two sets of positioning components 14 corresponding to the positive electrode assembly mechanism 5 and the negative electrode assembly mechanism 6, respectively. Each set of positioning components 14 includes two positioning cylinders 141 and two positioning plates 142. Both positioning cylinders 141 are linear cylinders, located on opposite sides of the processing transport line 2. The two positioning plates 142 are fixedly connected to the output shafts of the two positioning cylinders 141. Positioning blocks 143 matching the battery casing slots are provided on the surfaces of the two positioning plates 142 facing the processing transport line 2. The positioning plates 142 have holes 144 for conductive sheets to pass through, penetrating downwards through the positioning blocks 143. When the casing moves to the position corresponding to the positive electrode assembly mechanism 5 or the negative electrode assembly mechanism 6... After the corresponding workstation is reached, the two positioning cylinders 141 drive the corresponding positioning plates 142 to move downwards respectively. The positioning block 143 that does not correspond to the battery slot stops moving after contacting the surface of the housing. The positioning block 143 that corresponds to the battery slot is inserted into the battery slot and stops moving after the positioning plate 142 contacts the surface of the housing. Then, the second gripper 58 inserts the conductive sheet into the hole 144 and one end of the battery slot in turn. Finally, the positioning cylinder 141 is reset, and the upper end of the conductive sheet separates from the hole 144. This design uses the cooperation of the positioning block 143 and the battery slot to calibrate the position of the housing at the workstation. The hole 144 corresponds to both ends of the battery slot and is used to guide the conductive sheet to be inserted into the battery slot, which improves the auxiliary positioning function and facilitates the smooth insertion of the conductive sheet into the battery slot.

[0051] Further optimization, refer to Figure 10 As shown, the end face edges of the positioning block 143 facing the processing transport line 2 are all chamfered. This design can further improve the smoothness of the positioning block 143 being inserted into the battery slot and can help adjust the position of the housing relative to the work station.

[0052] As one specific implementation of the improvement, the number of components installed on the housing may vary due to missing conductive sheets or light guide pillars during assembly, thus affecting the housing's pass rate. To distinguish between qualified and unqualified housings, refer to... Figure 9As shown, it also includes a vision inspection component 12 located between the light guide post mounting mechanism 9 and the second flipping mechanism 10, and a sorting lane 13 positioned at the end of the processing transport line 2. The vision inspection component 12 is composed of a camera and a ring light source of existing technology. The camera is located above the ring light source and facing the processing transport line 2. The camera lens is located at the center line of the ring light source. During use, the assembled shell moves to the station of the vision inspection component 12, the camera takes a picture and feeds the picture information back to the controller for comparison with the standard picture in the controller. If the comparison shows that it is a qualified product, the controller feeds a signal to the feeding mechanism 11, and the shell that has been photographed moves to the discharging mechanism 11. The discharging mechanism 11 moves the shell to the conveyor line 3. If the comparison shows that it is a defective product, the controller feeds a signal to the feeding mechanism 11, and the shell that has been photographed moves to the discharging mechanism 11. The discharging mechanism 11 does not perform a clamping operation, and the next shell that moves to the discharging mechanism 11 will push the defective shell to the sorting lane 13. This design can classify and collect the shells, improving the pass rate of the assembled shells.
