Description

Technical Field

[0001] This utility model relates to the field of lighting processing equipment technology, and in particular to a fully automatic string light assembly machine. Background Technology

[0002] String lights are widely used in holiday decorations and landscape lighting due to their rich colors and flexible arrangement. String lights achieve their decorative purpose by connecting multiple light bulbs in series on the same wire, allowing for different lighting effects from each bulb.

[0003] However, existing parallel light string production equipment can only achieve partial automation, and some steps still require manual intervention. For example, key processes such as inserting copper sheets, assembling light strips and flexible heads, and pressing in light covers and cables still require manual intervention, resulting in low production efficiency and high labor costs. At the same time, manual operation is prone to significant errors, leading to a low yield rate of light string production.

[0004] Therefore, there is an urgent need for a highly automated, multifunctional, and seamlessly integrated fully automatic string light assembly equipment to solve the problems of low production efficiency and unstable quality in existing technologies, while meeting the market demand for diversified string light products.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] See Figures 2 to 11 This utility model provides a fully automatic light string assembly machine for automatically assembling light strings, thereby improving production efficiency and the yield rate of light strings, and thus reducing costs.

[0050] String lights are decorative items that can be wrapped around trees to create an ornamental effect. A string of lights consists of a cable and several light bulbs mounted on the cable. (See reference) Figure 1 The exploded view of a light bulb in a string of lights assembled by this fully automatic light string assembly machine shows that the top cover 71 is fastened to the upper part of the lamp head 72, and two copper plates 73 are respectively inserted into the slots of the lamp head 72. The cable (not shown in the figure) is held between the top cover 71 and the lamp head 72, so that the needle tip on the copper plate pierces the cable, realizing the conductivity of the light bulb; after the flexible head 74 and the light strip 75 are inserted, they are installed in the groove at the lower end of the lamp head 72, so that the upper conductive plate of the light strip 75 contacts the lower end of the copper plate 73, realizing the flow of current and making the lower light-emitting end of the light strip 75 light up; the protrusion at the opening of the lamp housing 76 is engaged with the lower end of the lamp head 72, and the light-emitting end of the light strip 75 is inserted into the lamp housing 76, thus completing the assembly. The structural principle of the light string can also be found in patent CN219889366U. 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 flexible head described in this application is similar to the rubber core in that patent; the lamp housing described in this application is similar to the light-transmitting lamp housing 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. The difference is that the light strip described in this application is long and narrow, with welded positive and negative conductive plates at the ends; and the cable described in this application has a two-parallel structure, with two corresponding copper sheets.

[0051] refer to Figure 2The fully automatic string light assembly machine includes a body 1, a first feeding device 2, a second feeding device 3, a third feeding device 4, and an integrated device 5. The body 1 includes a frame 11 and a first turntable 12 with multiple feeding positions arranged circumferentially. The frame 11 supports the entire equipment, and multiple transmission links are arranged at the lower part of the frame 11, thereby providing driving force to the upper devices through the transmission links. The first turntable 12 is mounted on the frame 11. In use, the first turntable 12 is driven to rotate by the motor on the lower side, thereby driving the feeding positions to move circumferentially to perform multi-step operations. The first feeding device 2 is used to feed the lamp head and copper sheet and assemble them into the feeding positions of the first turntable 12. Specifically, according to the rotation direction of the first turntable 12, the lamp head is first fed into the first turntable 12, and then the copper sheet is installed into the lamp head. The second feeding device 3 is used to feed and assemble the light strip and the flexible head. The second feeding device 3 includes a light strip conveying assembly 31, a flexible head feeding assembly 32, and an assembly assembly 33. The light strip conveying assembly 31 is used to convey the light strip to the assembly assembly 33, the flexible head feeding assembly 32 is used to feed the flexible head to the assembly assembly 33, and the assembly assembly 33 is used to assemble the light strip and the flexible head, and install the assembled light strip and the flexible head onto the lamp head of the first turntable 12. Specifically, the flexible head feeding assembly 32 first feeds the flexible head to the assembly assembly 33, and the assembly assembly 33 then moves the flexible head to the position of the light strip conveying assembly 31. The light strip conveying assembly 31 separates the light strip, feeds it, and inserts it into the flexible head to complete the assembly of the light strip and the flexible head. The third feeding device 4 is used to convey the lamp housing and assemble the lamp housing with the lamp head of the first turntable 12. The integrated device 5 is used to transport the assembled lamp head and lamp housing to the pressing position. Simultaneously, the integrated device 5 feeds the cable and top cover. The integrated device 5 presses the fed cable and top cover to the top of the lamp head, thereby completing the assembly and production of the entire light string.

[0052] Specifically, the first feeding device 2, the second feeding device 3, the third feeding device 4 and the integrated device 5 are arranged sequentially along the rotation direction of the first turntable 12. As the first turntable 12 rotates, each feeding position is moved to the position of each device, thereby completing each assembly step.

[0053] Furthermore, the first feeding device 2 includes a lamp head feeding assembly 21, a copper sheet feeding assembly 22, and a copper sheet detection assembly 23. In the rotation direction along the first turntable 12, the copper sheet feeding assembly 22 is located behind the lamp head feeding assembly 21, and the copper sheet detection assembly 23 is located behind the copper sheet feeding assembly 22. The lamp head feeding assembly 21 conveys the lamp head to one of the feeding positions, the copper sheet feeding assembly 22 conveys the copper sheet and inserts it into the lamp head at the feeding position, and the copper sheet detection assembly 23 slides to detect the position of the copper sheet.

[0054] Specifically, the lamp head feeding assembly 21 consists of a lamp head feeding tray 211, a lamp head conveyor belt 212, and a lamp head handling hand 213. The lamp head feeding tray 211 is a vibrating tray for feeding, which sorts and feeds the materials in the tray sequentially through vibration, which is existing technology. The lamp head conveyor belt 212 is connected to the lamp head feeding tray 211 and is driven by a motor to transport the lamp head to the picking position of the lamp head handling hand 213. The lamp head handling hand 213 is driven by the transmission linkage at the bottom of the frame 11. The lamp head handling hand 213 clamps the lamp head and moves it to one of the feeding positions of the first turntable 12. The feeding position is equipped with a gripper to hold the lamp head, thereby completing the lamp head feeding.

[0055] The first feeding device 2 also includes a lamp head rotating component 24, which is located at the front feeding position of the copper sheet feeding assembly 22. The end of the lamp head rotating component 24 is provided with a rotating head. When the lamp head moves to the lower side of the rotating head, the rotating head inserts downward into the lamp head and rotates horizontally by 90 degrees, thereby adjusting the position of the copper sheet insertion slot inside the lamp head to facilitate the subsequent insertion of copper sheets. It can be understood that the lamp head rotating component 24 is also provided with a detection component. When the detection component detects that the position of the lamp head is correct, it will not perform the rotation operation.

[0056] The copper sheet feeding assembly 22 includes a copper sheet feeding tray 221, a copper sheet conveyor belt 222, and a copper sheet inserter 223. The copper sheet feeding tray 221 is also a vibratory feeder, which is existing technology. The copper sheet conveyor belt 222 is connected to the copper sheet feeding tray 221. A channel for clamping and conveying copper sheets is provided in the middle of the copper sheet conveyor belt 222 to prevent the copper sheets from tilting or falling over. The copper sheets are conveyed to the picking position of the copper sheet inserter 223 by a motor drive. The copper sheet inserter 223 clamps the copper sheet at the picking position and moves it to the top of the lamp head of the first turntable 12, and then inserts the copper sheet into the copper sheet insertion slot of the lamp head, completing the first copper sheet insertion step.

[0057] The copper sheet detection assembly 23 is equipped with a micro-motion sensor and a cylinder at its end. The micro-motion sensor moves up and down under the drive of the cylinder. When the micro-motion sensor moves down and approaches the copper sheet, it triggers a signal to complete the copper sheet detection. When no copper sheet is detected, no signal is triggered.

[0058] This equipment has two sets of copper sheet feeding components 22 and copper sheet detection components 23 for inserting copper sheets into the two copper sheet insertion slots inside the lamp head. Each set of copper sheet detection components 23 has a set of copper sheet detection components 23 behind it. The last set of copper sheet detection components 23 also has a set of lamp head rotating parts 24 behind it, which is used to rotate the lamp head back to the correct position.

[0059] Furthermore, the light strip conveying assembly 31 includes a light strip layering component 311, a light strip cutting component 312, and a light strip flipping component 313. The light strip layering component 311 is provided with a layering clamping piece 311a, which swings to separate the light strip plate 331d. The light strip cutting component 312 moves up and down to cut the light strip plate 331d to form a light strip. The light strip flipping component 313 clamps the light strip and swings and flips it so that the light strip is vertically inserted into the soft head on the assembly assembly 33.

[0060] Specifically, the light strips are arranged in a plate-like shape before being loaded, that is, multiple light strips are arranged horizontally, similar to the shape of a ladder in real life. The light strip conveying assembly 31 also includes a light strip loading platform 331b and a light strip drive unit 331c. The light strip loading platform 331b is used to receive the falling light strip plate 331d, and the light strip drive unit 331c drives the light strip plate 331d on the light strip loading platform 331b to move forward. The light strip layering unit 311 is used to load the stacked light strip plates 331d one by one. The layering clips 311a on the light strip layering unit 311, through each swing, drop the light strip plate 331d located at the bottom layer onto the light strip loading platform 331b. Then, the light strip plate 331d on the platform is pushed forward and cut by the light strip cutting unit 312, so that the fixed edges on both sides of the light strip plate 331d are cut off, leaving only the strip-shaped light strips for subsequent loading.

[0061] Specifically, four layered clips 311a are provided and are located on both sides of the light strip plate 331d. The four layered clips 311a are driven by a connecting rod. The layered clips 311a have a circular structure and two levers are provided on the side. The two levers are vertically spaced and arranged circumferentially, that is, the positions of the two levers are offset relative to each other. The width of the vertical spacing between the two levers is the thickness of the light strip plate 331d. Initially, the lower lever supports the light strip plate 331d, and the connecting rod is activated to rotate the layered clamping plate 311a. The lower lever gradually detaches from the light strip plate 331d, while the upper lever gradually inserts into the gap between the bottom light strip plate 331d and the upper layer light strip plate 331d. As the layered clamping plate 311a rotates, the lower lever completely detaches from the bottom light strip plate 331d, and the bottom light strip plate 331d falls onto the light strip loading platform 331b, thus completing one loading cycle. Subsequently, the layered clamping plate 311a rotates in the opposite direction, the upper lever detaches from the light strip plate 331d, and the lower lever re-supports the light strip plate 331d for the next loading cycle.

[0062] The light strip cutting component 312 is located at the end of the light strip feeding platform 331b. The end of the light strip cutting component 312 is provided with a cutting blade and a moving mechanism. The moving mechanism drives the cutting blade to move up and down to cut the fixed edge of the side of the light strip plate 331d.

[0063] Furthermore, the light strip conveying assembly 31 also includes a light strip detection component 314 and a moving rotating component 315 located between the light strip cutting component 312 and the light strip flipping component 313. The end of the light strip detection component 314 is provided with an energizing device to detect the position of the conductive terminals of the light strip. The moving rotating component 315 drives the light strip to move and rotate 90 degrees to the left or right so that it can be clamped by the light strip flipping component 313.

[0064] The light strip detection component 314 is equipped with a driving component to move the energizing device at its end up and down and left and right. The energizing device detects whether the conductive sheet at the end of the light strip is energized. Furthermore, since the light strips on the light strip plate 331d are arranged in a Z-shape (the conductive sheet of the previous light strip faces right, and the conductive sheet of the next light strip faces left), the light strip detection component 314 needs to move left and right to align the positions of the conductive sheets on the light strips.

[0065] The movable rotating component 315 is located between the end of the light strip loading platform 331b and the light strip flipping component 313. The movable rotating component 315 is used to receive the inspected light strip and rotates horizontally 90 degrees to the left or right depending on the orientation of the conductive sheet on the light strip, thereby ensuring that the light-emitting end of the light strip always faces the side where the light strip flipping component 313 is located. The movable rotating component 315 includes a driving component to lift the light strip and move it back and forth and up and down, so that the light strip moves to the pickup point position of the light strip flipping component 313.

[0066] The light strip flipping component 313 includes a light strip clamping block 313a and a flipping drive component 313b. The light strip clamping block 313a is used to pick up and clamp the light-emitting end of the light strip. The flipping drive component 313b is connected to the light strip clamping block 313a to drive the light strip clamping block 313a to flip, thereby causing the light strip to flip vertically by 90 degrees, so that the conductive sheet of the light strip faces upward, ensuring that the conductive sheet is inserted into the flexible head on the assembly assembly 33. It can be understood that the light strip flipping component 313 is also provided with a light strip inserter. The light strip inserter picks up the light strip and moves it above the flexible head. The light strip inserter controls the insertion of the light strip and embeds the conductive sheet of the light strip into the flexible head.

[0067] The soft head feeding assembly 32 also includes a soft head vibrating plate, a soft head conveyor belt, and a soft head handling arm. It has a similar structure to the lamp head feeding assembly 21 mentioned above, and is existing technology so it will not be described in detail.

[0068] Furthermore, the assembly component 33 includes a second turntable 331, a flexible head rotating component 332, a dispensing component 333, and a baking component 334. The second turntable 331 includes multiple assembly positions. The flexible head rotating component 332 is respectively disposed at the front and rear positions of the light strip conveying component 31 and rotates the flexible head on the assembly position horizontally. The dispensing component 333 and the baking component 334 are located on the rear side of the light strip conveying component 31. The dispensing component 333 and the baking component 334 dispense glue and bake glue on the assembled flexible head and light strip, respectively.

[0069] Multiple assembly positions on the second turntable 331 are equipped with soft-head grippers 335. The soft-head grippers 335 clamp or release the soft head through two clamping blocks and springs. The soft-head feeding assembly 32 feeds the soft head to the soft-head grippers 335. The second turntable 331 rotates, moving the soft head to the next assembly position. The soft-head rotating component 332 is equipped with a rotating head and a driving component. The driving component drives the rotating head to move up and down. The rotating head clamps the soft head and rotates it horizontally by 90 degrees so that the lamp strip insertion slot on the lower side of the soft head is aligned with the lamp strip. After the lamp strip is inserted into the soft head, the second soft-head rotating component 332 clamps the soft head and rotates it back to the center position.

[0070] The dispensing component 333 and the baking component 334 are arranged along the rotation direction of the second turntable 331. The dispensing component 333 moves downward to dispense adhesive onto the flexible head on the second turntable 331, thereby fixing the lamp strip to the flexible head and preventing it from loosening. The baking component 334 is located at the rear assembly position of the dispensing component 333. The baking component 334 is a UV lamp. The baking component 334 bakes the flexible head after dispensing in the previous step. The baking component 334 is distributed in multiple assembly positions to ensure that the dispensing position on the flexible head is dried.

[0071] The second feeding assembly also includes a flexible tip inserter 34, which is located at the intersection of the second turntable 331 and the first turntable 12. The flexible tip inserter 34 is used to transport the assembled flexible tip and insert it into the flexible tip slot at the bottom of the lamp holder. The flexible tip slot is consistent with the appendix of patent CN219889366U. Figure 4 Similarly, the soft tip inserter 34 controls the clamping and insertion of the soft tip through the clamping structure and the driving structure, respectively. Specifically, the soft tip inserter 34 picks up the soft tip and moves it to the lower side of the lamp head on the first turntable 12. By moving upward, the soft tip is embedded in the soft tip groove at the lower part of the lamp head.

[0072] Furthermore, the third feeding device 4 includes a lamp housing conveying assembly 41, a lamp housing flipping assembly 42, and a lamp housing insertion assembly 43. The lamp housing conveying assembly 41 vibrates and conveys the lamp housing. The lamp housing flipping assembly 42 clamps the lamp housing and flips it to be placed in the lamp housing insertion assembly 43. The lamp housing insertion assembly 43 pushes the lamp housing to the feeding position of the first turntable 12. The lamp housing insertion assembly 43 pushes the lamp housing to insert the lamp strip.

[0073] The lamp housing conveying assembly 41 includes a lamp housing feeding tray and a lamp housing conveyor belt. The lamp housing conveyor belt is connected to the lamp housing feeding tray. The lamp housing feeding tray is a vibrating plate for feeding, and its structure is similar to that of the lamp head feeding tray 211 mentioned above.

[0074] The lamp housing flipping assembly 42 is located between the lamp housing conveying assembly 41 and the lamp housing insertion assembly 43. Because the lamp housing is vibrated during feeding, the opening of the lamp housing becomes heavier, causing it to face downwards, making subsequent insertion of the lamp housing and lamp head impossible. The lamp housing flipping assembly 42 is used to clamp and flip the lamp housing, thereby changing the orientation of the lamp housing opening. The lamp housing flipping assembly 42 places the flipped lamp housing into the lamp housing insertion assembly 43. The lamp housing insertion assembly 43 moves the lamp housing below the lamp head, allowing the light strip to enter the lamp housing through the opening. The lamp housing is then pushed upwards, completing the engagement between the lamp housing and the lamp head.

[0075] The lamp housing insertion assembly 43 includes a lamp housing moving part 431 and a lamp housing assembly part 432. The lamp housing moving part 431 is a strip-shaped conveyor belt. The lamp housing is held between the conveyor belts and transported to the lamp head below the first turntable 12. The lamp housing assembly part 432 is provided with a clamp and an upper block. The clamp picks up the lamp housing and moves upward, so that the light-emitting end of the lamp strip is inserted into the lamp housing. The upper block pushes the lamp housing up, so that the lamp housing and the lamp head are assembled.

[0076] Furthermore, the lamp housing flipping assembly 42 includes a lamp housing moving cylinder 421, a lamp housing picking head 422, and a gear drive 423. The lamp housing picking head 422 and the gear drive 423 are mounted on the drive end of the lamp housing moving cylinder 421. The lamp housing picking head 422 is mounted on the gear drive 423 and picks up the lamp housing. The gear drive 423 drives the picking head to flip 180 degrees.

[0077] The lamp housing is conveyed to the top of the lamp housing pickup head 422 via the lamp housing conveyor belt. The end of the lamp housing pickup head 422 has an arc-shaped structure. Driven by the lamp housing moving cylinder 421, the lamp housing pickup head 422 is inserted upward into the opening of the lamp housing to complete the pickup.

[0078] The gear drive component 423 includes two half-toothed gears, one of which is connected to the non-pickup end of the lamp housing pickup head 422. The gear rotates to drive the lamp housing pickup head 422 to rotate, thereby causing the lamp housing to rotate 180 degrees, so that the opening of the lamp housing changes direction, and under the drive of the lamp housing moving cylinder 421, it moves to the receiving point of the lamp housing moving component 431 to complete the rotation of the lamp housing.

[0079] Furthermore, the integrated device 5 includes a conveying component 51, a cable conveying component 52, a top cover feeding component 53, and a pressing component 54. The conveying component 51 clamps the lamp head and rotates it to the pressing position. The cable conveying component 52 punches holes in the cable and conveys the cable to the top of the lamp head. The top cover feeding component 53 feeds the cable and clamps the top cover, moving it to the top of the cable. The pressing component 54 is located above the pressing position and presses down on the top cover so that the top cover is fastened to the lamp head.

[0080] The transport assembly 51 is located between the first turntable 12 and the pressing member 54. The transport assembly 51 is equipped with a clamping block for holding the lamp head and a rotating device. The rotating device drives the clamping block to move the assembled lamp head and lamp housing back and forth.

[0081] The top cover feeding assembly 53 is used to feed the top cover. The top cover feeding assembly 53 includes a top cover feeding tray, a top cover conveyor belt, and a top cover handling arm. The top cover feeding tray is connected to the top cover conveyor belt. The top cover feeding tray uses a vibratory feeder. 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 component. The clamping block is set on the flipping component and is used to clamp the top cover. Since the top cover's fastening surface faces upward after vibratory feeding, it needs to be flipped to fasten with the upper end of the lamp head. The flipping component is used to flip the top cover and move it to the upper part of the lamp head for subsequent pressing steps.

[0082] Furthermore, the cable conveying assembly 52 includes a cable conveying drive wheel 521 and a punching component 522. The cable conveying drive wheel 521 rotates to clamp and drive the cable to move. The punching component 522 includes a punching cylinder 522a and upper punching blocks 522b and lower punching blocks 522c that are engaged vertically. The end of the punching cylinder 522a is provided with a punching needle 522d for punching the cable. The upper punching blocks 522b and lower punching blocks 522c are engaged to form a first channel for the punching needle 522d to move up and down, and a second channel for the cable to move laterally. The first channel and the second channel are vertically connected.

[0083] The cable feed drive wheel 521 is fixed on the frame 11. The cable feed drive wheel 521 includes an upper wheel and a lower wheel that are approximately in contact with each other. The distance between the upper wheel and the lower wheel is approximately the thickness of the cable. When the upper wheel and the lower wheel roll relative to each other, the cable located between them will be driven forward, thereby achieving a stable feeding effect.

[0084] The punching component 522 is located behind the cable drive wheel 521 and is used to punch holes in the cable. Explanation: Cable punching is used to achieve series and parallel connections for light strings. For example, when light bulbs need to be connected in parallel, two copper plates inside the bulb are inserted into the two electrode wires of the cable, respectively connecting the positive and negative electrodes. This allows the current to directly form a circuit loop when passing through the bulb, achieving parallel connection. When light bulbs need to be connected in series, a hole is punched in one of the electrode wires of the cable, such as the negative wire. Current would be interrupted when passing through this hole, preventing current flow. By simultaneously inserting two copper plates into the same electrode wire, with the two plates positioned to the left and right of the hole on the negative wire, current can flow through the two copper plates when passing through the hole, thus forming a series circuit. Different signal controls for the lights are achieved through series and parallel connections.

[0085] The punching component 522 includes a punching cylinder 522a and two punching blocks that are engaged vertically. The punching cylinder 522a is used to drive the punching needle 522d to move up and down to punch the cable on the lower side. The separate upper punch block 522b and lower punch block 522c facilitates processing and mold opening. The upper punch block 522b and lower punch block 522c are interlocked by a dovetail groove structure. The upper punch block 522b has a vertically penetrating first channel, and the lower punch block 522c also has a vertically penetrating first channel at the corresponding position, allowing the punching needle 522d to move up and down within the first channel. The lower side of the upper punch block 522b has a groove, and the upper side of the upper punch block 522b has a groove. When the upper and lower punch blocks 522c are interlocked, the two grooves form a horizontal second channel. The second channel is used for cable insertion and movement, and the second channel is perpendicularly connected to the first channel to ensure that the punching needle 522d can accurately punch the cable.

[0086] The cable conveying assembly 52 also includes a wire cutter 523, located behind the punching member 522. When the length of the produced light string meets the requirements, the wire cutter 523 is activated to cut the cable, thereby completing the entire production process of one light string. The wire cutter 523 includes a cutter head and a drive unit. The drive unit can be a cylinder or a connecting rod. The cutter head is located at the end of the drive unit, and the drive unit drives the cutter head to move up and down to cut the cable.

[0087] Furthermore, the integrated device 5 also includes a lamp housing clamping assembly 55 located at the pressing position. The lamp housing clamping assembly 55 includes a first clamping block 551, a second clamping block 552, and a clamping drive member 553. The clamping drive member 553 drives the first clamping block 551 and the second clamping block 552 to move closer or further away from each other. The first clamping block 551 and the second clamping block 552 are each provided with a clearance groove 554 for accommodating the lamp housing on opposite sides. The groove wall of the clearance groove 554 is in contact with the surface of the lamp housing.

[0088] The lamp housing clamping assembly 55 is used to clamp the lamp housing, thereby ensuring that the lamp housing will not be subjected to excessive force and crack when the pressing member 54 presses the top cover to the top of the lamp head. The first clamping block 551 and the second clamping block 552 are located on both sides of the pressing position, and the first clamping block 551 and the second clamping block 552 move under the drive of the driving member. Specifically, the driving member is a linkage structure, and the two linkages rotate through gears to drive relative movement. The clearance grooves 554 of the first clamping block 551 and the second clamping block 552 are aligned. When the first clamping block 551 and the second clamping block 552 are in contact, the two clearance grooves 554 merge, so that the lamp housing is wrapped between the clearance grooves 554. The shape of the clearance grooves 554 after merging is the same as the shape of the lamp housing, so that the outer surface of the lamp housing can fit against the groove wall of the clearance groove 554. When the pressing component 54 presses down on the top cover, the first clamping block 551 and the second clamping block 552 fit against the lamp housing, dispersing the force on the lamp housing and preventing excessive force on one point of the lamp housing, which could lead to damage.

[0089] The pressing component 54 is equipped 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 onto the upper part of the lamp head. At the same time, the cable is pressed between the top cover and the lamp head, and during the pressing process, the copper sheet pierces into the cable.

[0090] The fully automatic string light assembly machine also includes a feeding device 6, which includes a transmission belt and a motor. The motor drives the transmission belt to move in order to feed the assembled string lights.
