[0048] See Figures 1 to 14 The present invention provides a new type of automatic lamp assembly machine for automatically assembling lamp string heads, thereby improving production efficiency and the yield rate of lamp strings, thereby reducing costs.

[0049] A light string is a decorative object that can be wrapped around a tree to create a decorative effect. The light string consists of a cable and several bulbs mounted on the cable. This device is used to assemble the light string head at the top of the light string. For reference, the lamp head described in this application is similar to the lamp head body in that patent, the copper sheet described in this application is similar to the metal terminal in that patent, the wick described in this application is similar to the combination of the rubber core and the light source in that patent, the cable described in this application is similar to the power cord in that patent, and the top cover described in this application is similar to the lamp head top cover in that patent.

[0050] refer to Figure 1 The new automatic lamp assembly machine includes a body 1, a first loading device 2, a second loading device 3 and an integrated device 4. The body 11 includes a frame 1111 and a turntable 1212 with multiple loading positions arranged along the circumference. The frame 1111 is used to support the entire equipment, and a plurality of transmission connecting rods are provided at the lower part of the frame 1111, so as to provide driving force for each device on the upper side through the transmission connecting rods. The turntable 1212 is installed on the frame 1111. When in use, the turntable 1212 is driven to rotate by the motor on the lower side, thereby driving the loading position to move circumferentially, so that each loading position can perform multi-step operations. The first loading device 2 includes a lamp holder loading assembly 21 and a double copper sheet loading assembly 22. The lamp holder loading assembly 21 is used to load the lamp holder to the loading position on the turntable 12. The lamp holder loading assembly 21 and the double copper sheet loading assembly 22 are respectively positioned at the loading positions of the turntable 12, and the double copper sheet loading assembly 22 is located at the rear loading position of the lamp holder loading assembly 21. The double copper sheet loading assembly 22 can insert the copper sheet into the lamp holder on the turntable 12. The second loading device 3 is provided at the rear loading position of the first loading device 2. The second loading device 3 is used to load the lamp wick, and the second loading device 3 simultaneously inserts the lamp wick into the lamp holder on the turntable 12, thereby completing the assembly of the lamp holder. The integrated device 4 is located on the rear side of the second loading device 3. The integrated device 4 is used to transport the assembled lamp heads on the turntable 12 to the assembly position. The integrated device 4 is also used to load cables and top covers. The integrated device 4 presses the loaded cables and top covers to the top of the lamp heads, thereby completing the assembly production of the lamp string heads.

[0051] Specifically, the first loading device 2, the second loading device 3 and the integrated device 4 are arranged in sequence along the rotation direction of the turntable 12. As the turntable 12 rotates, each loading position is driven to move to the corresponding position of each device, so that the lamp head completes each assembly step.

[0052] The lamp holder loading assembly 21 includes a lamp holder loading tray 211, a lamp holder conveyor belt 212, and a lamp holder handling hand 213. The lamp holder loading tray 211 is connected to the lamp holder conveyor belt 212. The lamp holder loading tray 211 is loaded by vibration, so that the lamp holders in the tray are moved to the lamp holder conveyor belt 212 in sequence. The vibration tray loading is a prior art and will not be described in detail. A driving motor is provided at the bottom of the lamp holder conveyor belt 212 to drive the lamp holders on the lamp holder conveyor belt 212 to move. The lamp holder handling hand 213 is provided at the end of the lamp holder conveyor belt 212. The lamp holder handling hand 213 is provided with a connecting rod driving assembly and a lamp holder clamping hand. The connecting rod driving assembly is connected to the connecting rod at the bottom of the frame 11, and the lamp holder clamping hand is connected to the connecting rod driving assembly. The connecting rod driving assembly drives the lamp holder clamping hand to move up and down and forward and backward, so that the lamp holder clamping hand clamps the lamp holder on the lamp holder conveyor belt 212 and transports it to the loading position on the turntable 12. Each loading position of the turntable 12 is provided with a clamping hand for clamping the lamp head carried by the lamp head carrying hand 213, thereby completing the loading of the lamp head.

[0053] Furthermore, the double copper sheet loading assembly 22 includes a copper sheet loading tray 221, a copper sheet conveyor belt 222 and a copper sheet handling arm 223. The copper sheet loading tray 221 is connected to the copper sheet conveyor belt 222. The end of the copper sheet conveyor belt 222 is aligned with the loading position of the turntable 12. The copper sheet handling arm 223 moves between the turntable 12 and the copper sheet conveyor belt 222 and handles the copper sheet.

[0054] The copper sheet loading tray 221 is connected to the copper sheet conveyor belt 222. The copper sheet loading tray 221 loads the copper sheets in the tray in sequence by vibration, and the copper sheet conveyor belt 222 drives the copper sheets to the picking point of the copper sheet handling hand 223 through the driving motor, and then the copper sheet handling hand 223 picks up the copper sheets and inserts them into the lamp holder on the turntable 12.

[0055] Furthermore, two copper sheet loading trays 221 are provided, and the copper sheet conveyor belt 222 includes two conveying channels 222a and is respectively connected to the two copper sheet loading trays 221, and the two conveying channels 222a respectively convey copper sheets with opposite needle tip deviations.

[0056] The specific structure of the copper sheet and the structure of the copper sheet inserted into the lamp holder can refer to the attached drawings of the above patent CN219889366U. Figure 3 The lamp head of the light string needs to be loaded with three copper sheets, including a copper sheet in the middle and two copper sheets on both sides. The three copper sheets correspond to the two electrode wires and one light signal wire of the cable. In order to ensure that the needle tip of each copper sheet can be inserted into each wire of the cable, the copper sheet in the middle does not need to be deflected and can be directly inserted into the leftmost wire of the cable. The copper sheets on both sides are arranged horizontally, so the deflection of the needle tip needs to be adjusted to make it correspond to the middle electrode wire and the rightmost wire of the cable.

[0057] The conveying channels 222a on the copper sheet conveyor belt 222 are used to clamp the copper sheets, keeping them upright during movement. The two conveying channels 222a are connected to the openings of the two copper sheet loading trays 221. One conveying channel 222a is set to load copper sheets with the needle tips facing forward, and the other conveying channel 222a is set to load copper sheets with the needle tips facing backward. The specific deflection direction of the copper sheet needle tips can be adjusted by turning the copper sheet loading tray 221. As long as the two conveying channels 222a can respectively transport two rows of copper sheets with the needle tips facing opposite directions, it is sufficient.

[0058] Two sets of dual copper sheet loading assemblies 22 are provided, each set loading a single copper sheet. During each copper sheet handling process, the copper sheet handling arm 223 can select one of the two rows of copper sheets to grip and handle, completing the insertion of a copper sheet. The copper sheet handling arm 223 comprises a copper sheet clamp 223a and a clamping driver 223b. The copper sheet clamp 223a is mounted on the clamping driver 223b. The clamping driver 223b comprises a connecting rod driver 223c and a cylinder driver 223d, which drive the copper sheet clamp 223a to move back and forth, left and right, and up and down, thereby moving the copper sheet clamp 223a back and forth between the copper sheet conveyor belt 222 and the lamp head. Specifically, the clamping driver 223b drives the copper sheet clamp 223a forward and backward and up and down via the connecting rod driver 223c, while the clamping driver 223b drives the copper sheet clamp 223a to fine-tune its left and right movements via the cylinder driver 223d. It should be noted that the copper sheet clamping piece 223a selects the left and right rows of copper sheets for picking up by fine-tuning the movement left and right. The specific selection result needs to be adjusted according to the circuit of the light string. By selecting copper sheets with different deviations and inserting different wires, the control effect of the light string circuit can be achieved.

[0059] Furthermore, the first feeding device 2 also includes a single copper sheet feeding component 24 and a lamp head rotating component 23. The lamp head rotating component 23 is arranged between the double copper sheet feeding component 22 and the single copper sheet feeding component 24 and rotates the lamp head. The single copper sheet feeding component 24 is used to feed the copper sheet with the needle tip centered.

[0060] The single copper sheet loading assembly 24 has a similar structure to the double copper sheet loading assembly 22. The single copper sheet loading assembly 24 also includes a copper sheet loading tray 221, a copper sheet conveyor belt 222 and a copper sheet handling arm 223. The difference is that the single copper sheet loading assembly 24 only includes one copper sheet loading tray 221, and the copper sheet conveyor belt 222 is only provided with a conveying channel 222a. The copper sheet handling arm 223 is not provided with a cylinder driving part 223d for driving left and right movement. The copper sheet handling arm 223 only clamps a single row of copper sheets, and transports and inserts the copper sheets by moving up and down and forward and backward, without the need for left and right micro-movement to select the copper sheets. It should be noted that the two sets of double copper sheet loading components 22 are used to load and insert the copper sheet grooves on both sides of the lamp head respectively, and the single copper sheet loading component 24 is used to load and insert the copper sheet groove in the middle of the lamp head. Since the copper sheet groove in the middle is arranged vertically, that is, the same as the extension direction of the cable, the copper sheet needle tip clamped by the single copper sheet loading component 24 is not deviated and is located in the center of the copper sheet.

[0061] Because the copper sheet slots on both sides of the lamp holder extend perpendicular to the copper sheet slot in the middle, after the copper sheets on both sides are inserted, the lamp holder needs to be rotated 90 degrees to change the extension direction of the copper sheet slot in the middle to allow the copper sheet of the single copper sheet loading assembly 24 to be inserted. The lamp holder rotation assembly 23 is set at the front loading position of the single copper sheet loading assembly 24 to rotate the lamp holder. The lamp holder rotation assembly 23 includes a driving member and a rotating head. The driving member is driven by a connecting rod. It can be understood that the driving member can also be driven by a rotating motor that can be raised and lowered. The rotating head is connected to the driving end of the driving member. The driving member drives the rotating head to move up and down. The rotating head rotates itself through the meshing rotation of the gear structure. When the turntable 12 drives the lamp holder to rotate to the bottom of the lamp holder rotation assembly 23, the driving member drives the rotating head to descend so that the rotating head can be inserted into the upper part of the lamp holder. The gear rotation drives the lamp holder to rotate 90 degrees, thereby changing the extension direction of the copper sheet slot in the middle of the lamp holder to facilitate the subsequent insertion of the single copper sheet loading assembly 24.

[0062] The first feeding device 2 also includes a lamp holder positioning member 25. The lamp holder positioning member 25 is arranged at the feeding position between the lamp holder feeding assembly 21 and the double copper sheet feeding assembly 22. The lamp holder positioning member 25 has similar functions to the lamp holder rotating assembly 23. The lamp holder positioning member 25 is used to rotate the lamp holder and determine the direction of the lamp holder. Specifically, the lamp holder positioning member 25 includes a rotating motor, a rotating clamp and a moving part. The rotating cylinder is arranged on the moving part. The rotating clamp is located at the driving end of the rotating motor. The rotating clamp is provided with a detection member for identifying the direction and position of the copper sheet slot on the lamp holder. Since the direction and position of the three copper sheet slots in the lamp holder need to be determined before the copper sheet is inserted, rotation positioning is required to ensure that the extension direction of the copper sheet slot is the same as the direction of the subsequent copper sheet insertion. After the lamp holder loading assembly 21 loads the lamp holder, the lamp holder is driven by the turntable 12 to the bottom of the lamp holder positioning part 25, and the moving part drives the rotating motor and the rotating clamp to move, and drives the rotating clamp to descend to insert into the upper part of the lamp holder. The rotating clamp identifies the direction of the copper sheet groove in the lamp holder through the detection part, and then the rotating motor drives the rotating clamp to rotate left or right.

[0063] Furthermore, the first feeding device 2 also includes a copper sheet detection component 26, which is located at the rear feeding position of the double copper sheet feeding component 22. The end of the copper sheet detection component 26 is provided with a sensor to detect the position of the copper sheet needle tip in the lamp holder.

[0064] The copper sheet detection assembly 26 includes a vertical driving member 261, a transverse driving member 262, a detection slide core 263 and a fine motion member 264. The transverse driving member 262 is arranged on the vertical driving member 261 to drive the transverse driving member 262 to move up and down. The detection slide core 263 and the fine motion member 264 are arranged on the transverse movement to drive the detection slide core 263 and the fine motion member 264 to move transversely. The detection slide core 263 is installed on the fine motion member 264, and then drives the detection slide core 263 to move vertically, so that the detection slide core 263 slightly touches the needle tip of the copper sheet downward to detect the deflection direction of the copper sheet needle tip. Specifically, the end of the detection slide 263 is provided with two side-by-side sensing elements, which correspond to the left and right deflections of the copper sheet needle tip, respectively. When the detection slide 263 is driven by the micro-movement element 264, it moves slightly downward so that one of the left and right sensing elements touches the copper sheet needle tip, thereby detecting the deflection direction of the copper sheet needle tip and controlling the next set of dual copper sheet feeding assemblies 22 to feed another copper sheet. It should be noted that the vertical drive element 261 and the horizontal drive element 262 can be driven by connecting rods or cylinders, and the micro-movement element 264 is driven by a cylinder. The detection slide 263 can also be configured with a soft head to prevent damage to the copper sheet.

[0065] Furthermore, the second loading device 3 includes a wick loading tray 31, a wick conveyor belt 32 and a wick assembly component 33. The wick loading tray 31 is connected to the wick conveyor belt 32. The wick conveyor belt 32 transports the wick to the picking point of the wick assembly component 33. The wick assembly component 33 carries the wick and installs it to the lamp head on the turntable 12.

[0066] The wick loading tray 31 is a vibrating tray for loading, and the wick conveyor belt 32 clamps and conveys the wick. The wick loading tray 31 and the wick conveyor belt 32 are similar in structure to the above-mentioned lamp holder loading tray 211 and the lamp holder conveyor belt 212, and will not be described in detail.

[0067] Furthermore, the wick assembly component 33 includes a wick clamp 331, a pressing piece 332 and a wick driving piece 333. The wick clamp 331 picks up the wick and moves it to the lower side of the lamp head. The pressing piece 332 is installed on the wick driving piece 333 and is aligned with the wick on the wick clamp 331 up and down. The pressing piece 332 pushes up the wick to fix it to the lamp head.

[0068] The wick assembly assembly 33 includes a wick gripper 331, a pressing member 332, and a wick driver 333. The wick gripper 331 includes two clamps that are relatively close or relatively far apart, and a clamp control member. The clamp control member is connected to a connecting rod at the bottom of the frame 11, and the clamps are mounted on the clamp control member so that the clamp control member controls the clamps to clamp or open. The wick gripper 331 is mounted on the wick driver 333, and the wick driver 333 drives the wick gripper 331 to move vertically and laterally. Specifically, the wick driver 333 drives the wick gripper 331 to move via a connecting rod or a cylinder. Driven by the wick driver 333, the wick gripper 331 moves between the wick conveyor belt 32 and the lamp holder, so that the wick is transported from the wick conveyor belt 32 to the bottom of the lamp holder and a portion of the wick enters the lamp holder.

[0069] The pressing member 332 is mounted on the wick driver 333. The pressing member 332 is located directly below the wick gripper 331 and is used to press the wick upward so that the wick is inserted into the lower portion of the lamp holder. The pressing member 332 includes a push head 332a and an upper push cylinder 332b. The push head 332a is mounted on the driving end of the upper push cylinder 332b. When the wick gripper 331 grips the wick, the wick driver 333 drives the wick gripper 331 and the pressing member 332 to move as a whole, so that the wick moves to the bottom of the lamp holder and the end of the wick is inserted into the lamp holder to prevent the wick from falling. At this time, the wick gripper 331 separates to loosen the wick, and the upper push cylinder 332b pushes the push head 332a slightly upward to push the wick into the groove buckle at the bottom of the lamp holder, thereby completing the installation and fixation of the wick and the lamp holder.

[0070] The new automatic lamp assembly machine also includes an optometry device 5, which is arranged at the rear loading position of the second loading device 3. The optometry device 5 detects the assembled lamp head and wick to ensure that the wick can be lit normally. The optometry device 5 is provided with a conductive head and a lifting part. The lifting part drives the conductive head to move, and the conductive head contacts the copper sheet to generate a current circuit to detect whether the wick is lit normally.

[0071] Furthermore, the integrated device 4 includes a conveying component 41, a cable conveying component 42, a top cover loading component 43 and a pressing piece 44. The conveying component 41 clamps the lamp head and rotates it to the assembly position. The cable conveying component 42 conveys the cable to the top of the lamp head. The top cover loading component 43 loads and clamps the top cover to move it above the cable. The pressing piece 44 is located above the assembly position. The pressing piece 44 presses down the top cover so that the top cover is buckled onto the lamp head.

[0072] The transport assembly 41 is located between the turntable 12 and the pressing member 44. The transport assembly 41 is used to clamp the lamp head and transport and transfer it. The transport assembly 41 is provided with a clamping block and a rotating member. The clamping block is installed on the rotating member and is used to clamp the lamp head. The rotating member drives the clamping block to transport the assembled lamp head back and forth.

[0073] The top cover loading assembly 43 is used to load the top cover. It includes a top cover loading tray, a top cover conveyor belt, and a top cover handling arm. The top cover loading tray and the top cover conveyor belt are connected. The top cover loading tray is fed by a vibrating plate, and the top cover conveyor belt transports the top cover to the pickup point of the top cover handling arm. The top cover handling arm includes a clamping block and a flipping member. The clamping block is mounted on the flipping member and is used to clamp the top cover. Since the top cover's engaging surface faces upward after vibrating loading, it needs to be flipped to engage with the upper end of the lamp holder. The flipping member is used to flip the top cover and move it to the upper part of the lamp holder for the subsequent pressing step.

[0074] Furthermore, the cable conveying assembly 42 includes a wire transmission wheel 421 and a punching piece 422. The wire transmission wheel 421 clamps the cable up and down, and the cable transmission wheel rotates to convey the cable. The punching piece 422 is arranged on one side of the wire transmission wheel 421 to punch holes in the cable.

[0075] The wire feeding drive wheel 421 is fixed to the frame 11 and includes an upper wheel and a lower wheel positioned adjacent to each other. The width of the gap between the upper and lower wheels is roughly the thickness of the cable. The upper wheel can be fine-tuned by a crank, thereby changing the gap between the upper and lower wheels according to the thickness of the cable. When the upper and lower wheels roll relative to each other, the cable between them is driven forward, thereby achieving a stable feeding effect.

[0076] The punching member 422 is located at the rear side of the transmission wheel 421, and is used to punch holes in the cable. Explanation: Punching holes in the cable is used to achieve series and parallel connection of the light string. The cable in this device includes three conductors. For example, when the light bulbs need to be connected in parallel, the copper sheets on both sides of the lamp holder are respectively inserted into the two electrode conductors of the cable, and the copper sheet in the middle is inserted into the signal conductor, that is, the two copper sheets are respectively connected to the positive and negative electrodes, so that the current can directly form a circuit loop when passing through the light bulb to achieve parallel connection; when the light bulbs need to be connected in series, a hole is punched on one of the electrode conductors of the cable, such as punching a hole in the negative conductor. When the current passes through the punched hole, the power will be cut off, resulting in the inability of the current to pass through. By changing the needle tip deflection of the copper sheet, the two copper sheets are simultaneously inserted into the same electrode wire, and the two copper sheets are respectively on the left and right sides of the punching position of the negative conductor. In this way, when the current passes through the punching position, it will pass through the two copper sheets to achieve current flow, thereby forming a series circuit. Different signal control of the light is achieved through series and parallel connection.

[0077] Furthermore, two punching members 422 are provided, and the two punching members 422 punch holes in the middle and sides of the cable respectively. The punching members 422 include a punching cylinder 422a and an upper punching block 422b and a lower punching block 422c that are buckled together. A punching needle 422d for punching the cable is provided at the end of the punching cylinder 422a. The upper punching block 422b and the lower punching block 422c are buckled together to form a first channel for the punching needle 422d to move up and down, and a second channel for the cable to move laterally. The first channel is vertically connected to the second channel.

[0078] The two punching members 422 punch holes in the two electrode conductors of the cable. After one punching member 422 punches a hole, the other punching member 422 does not. The punching members 422 include a punching cylinder 422a and two punching blocks that snap together. The punching cylinder 422a is used to drive the punching needle 422d to move up and down to punch the cable on the lower side. The upper punching block 422b and the lower punching block 422c are separated, which can make mold processing more convenient. The upper punching block 422b and the lower punching block 422c are buckled up and down through a dovetail groove structure. The upper punching block 422b is provided with a vertically penetrating first channel, and the corresponding position of the lower punching block 422c is also provided with a vertically penetrating first channel, so that the punching needle 422d can move up and down in the first channel; a groove is provided on the lower side of the upper punching block 422b, and a groove is provided on the upper side of the upper punching block 422b. When the upper and lower punching blocks 422c are buckled, the two grooves form a horizontal second channel, and the second channel is used for cable insertion and movement, and the second channel is vertically connected to the first channel to ensure that the punching needle 422d can accurately punch the cable. It should be noted that for the punching member 422 used to punch the middle electrode conductor, its first channel is also located in the middle position, so that the punching needle 422d corresponds to the middle electrode conductor. For the punching member 422 used to punch the side electrode conductor, its first channel is also located in the side position, so that the punching needle 422d corresponds to the side electrode conductor. The signal conductors on the other side are not punched, so that the central copper sheet is always inserted into the signal conductor.

[0079] The cable conveying assembly 42 also includes a cutting element 423, located behind the punching element 422 along the cable conveying direction. When the length of the light string head produced meets the required length, the cutting element 423 is activated to cut the cable, thus completing the entire production process of a light string head. The cutting element 423 includes a cutting head and a driving element. The driving element can be a cylinder or a connecting rod structure. The cutting head is mounted at the end of the driving element, which drives the cutting head up and down to cut the cable.

[0080] The pressing member 44 is also provided with a driving structure and a pressing head. The pressing head is connected to the driving structure. The driving structure drives the pressing head to move up and down to press the top cover to the upper part of the lamp head. At the same time, the cable is pressed between the top cover and the lamp head. In the process of pressing the top cover into the lamp head, the copper sheet is synchronously inserted into the cable.

[0081] The novel automatic lamp assembly machine further includes a blanking device 6, which is located at the discharge position of the integration device 4. The blanking device 6 includes a transmission belt and a motor. The motor drives the transmission belt to move to blank the assembled light string heads.
