Description

Technical Field

[0001] The invention relates to a stamping device, in particular to a lamp tube bracket forming line. Background Art

[0002] During the forming process of the lamp tube bracket, it is necessary to punch holes in the lamp tube bracket to facilitate the connection with the lamp holder plug during the overall assembly. Currently, before punching the lamp tube bracket, it is necessary to first cut a whole continuous lamp tube bracket according to the required length with a cutting knife, and then send it to the punching equipment for punching processing. This cutting method is inefficient and requires a large loss of the cutting knife. After technical improvements, the lamp tube bracket can be cut by punching a cutting knife. This method is more efficient and requires less loss of the cutting knife. However, the end position of the lamp tube bracket will be deformed during the punching process. If it is directly sent to the punching equipment for processing, it is easy to cause aggravated deformation and affect the quality of the lamp tube processing. Therefore, a device with better processing and forming effect is urgently needed. Summary of the invention

[0003] The object of the present invention is to provide a lamp tube bracket forming line to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problem is:

[0005] A lamp tube bracket forming line includes: a conveying device having a conveying surface extending in a front-to-rear direction; a feeding mechanism located on the upstream side of the conveying device, the feeding mechanism having a feeding frame that can move downward toward or upward away from the conveying surface; a punching and shaping mechanism including working units located on the left and right sides of the conveying device, the working units including a first base, a first upper mold and a first lower mold arranged in the first base, the first base can move in a direction approaching or away from the conveying surface, a shaping mold is arranged on the side of the first upper mold facing the conveying surface, the first lower mold is provided with a shaping block and a punching rod, the first upper mold and the first lower mold can approach each other so that the shaping block abuts against the shaping mold, and the punching rod penetrates upward into the shaping block and the shaping mold.

[0006] The technical solution has at least the following beneficial effects: the lamp tube bracket that needs to be punched is sent to the conveying surface of the conveying device, and the conveying surface moves, driving the lamp tube bracket to move to the punching and shaping mechanism. At this time, the first bases in the two working units on the left and right sides respectively approach the conveying surface, so that the shaping molds located on the left and right sides of the lamp tube bracket respectively enter the two ends of the lamp tube bracket to position the lamp tube bracket left and right, and the first lower mold approaches the first upper mold so that the shaping block of the first lower mold abuts against the lamp tube bracket, and the lamp tube bracket is pressed against the shaping mold to flatten the part of the lamp tube bracket that is deformed due to punching. At the same time, the punching rod in the first lower mold also moves up relative to the shaping block and passes through the lamp tube bracket to punch the lamp tube bracket. The shaping block presses the bottom side of the lamp tube bracket against the bottom side of the shaping die, effectively preventing the punching rod from pulling and deforming the surface of the lamp tube bracket when punching the lamp tube bracket, thereby improving the punching processing quality of the lamp tube bracket. After completion, the first upper mold and the first lower mold are separated from each other, the punching rod withdraws from the shaping block and the lamp tube bracket, and the first base and the second base move away from each other, so that the two ends of the lamp tube bracket withdraw from the shaping die respectively. At this time, the lamp tube bracket falls onto the conveying surface and is continued to be transferred to the next workstation by the conveying surface. In this way, when punching the lamp tube bracket, the end position of the lamp tube bracket can be flattened and shaped at the same time, and the pulling and deformation of the position near the punching hole during the punching process can be reduced, thereby improving the quality and efficiency of the punching processing of the lamp tube bracket.

[0007] As a further improvement of the above technical solution, the present invention also includes a first material blocking mechanism, which includes a first material blocking drive and a first material blocking member. The first material blocking drive is located beside the conveying surface, and the first material blocking drive is connected to the first material blocking member. The first material blocking drive can drive the first material blocking member to protrude upward or retract downward into the conveying surface. The first material blocking drive provides a driving force for the first material blocking member to move up and down. Before the lamp tube holder moves into position with the conveying surface, the first material blocking drive drives the first material blocking member to extend upward from the conveying surface to block the movement of the lamp tube holder, thereby ensuring the accuracy of the transfer of the lamp tube holder on the conveying surface and improving the accuracy of the alignment of the lamp tube holder and the shaping mold. After the punching process of the lamp tube holder is completed, the first material blocking drive drives the first material blocking member downward to below the conveying surface, and the lamp tube holder can continue to move on the conveying surface.

[0008] As a further improvement of the above technical solution, the present invention also includes a first pressing mechanism, which includes a first pressing drive and a first pressing block. The first pressing drive is located above the conveying device, and the first pressing drive is connected to the first pressing block. The first pressing block and the shaping die are opposite to each other in the left-right direction, and the first pressing drive can drive the first pressing block to move up and down. The first pressing drive can provide a driving force for the first pressing block to move in the up-and-down direction. When the lamp tube holder moves into position with the conveying surface, the first pressing drive drives the first pressing block to move downward, and the first pressing block is used to press the lamp tube holder against the conveying device, thereby further positioning the lamp tube holder. At this time, the first bases on the left and right sides of the lamp tube holder are close to each other, ensuring that the two shaping dies can enter the two ends of the lamp tube holder respectively, and when the lamp tube holder is punched and shaped, the stability of the position of the lamp tube holder can also be ensured. After the processing of the lamp tube holder is completed, the first pressing drive drives the first pressing block to move up and reset.

[0009] As a further improvement of the above technical solution, the first lower mold includes a lower template, a first guide column, a spring and a pressure plate. The lower template can move up and down in the first base. The pressure plate is located above the lower template. The first guide column is connected to the bottom side of the pressure plate. The bottom of the first guide column is slidably connected in the lower template. The spring is connected between the pressure plate and the lower template. The shaping block is connected to the top side of the pressure plate. The punching rod is connected to the top side of the lower template. The top end of the punching rod is inserted into the pressure plate. The pressing plate is limited by the sliding of the first guide column and the lower template, and the spring provides support for the pressing plate. At this time, the pressing plate and the lower template form a whole, and the whole is moved upward close to the first upper mold. The pressing plate first contacts the first upper mold. At this time, the shaping block on the top side of the pressing plate is pressed against the bottom side of the lamp tube bracket. As the lower template gradually moves upward, the spring is gradually compressed, and the pressure of the shaping block on the lamp tube bracket gradually increases, and the deformed position on the lamp tube bracket is flattened and shaped. When the punching rod on the top side of the lower template protrudes upward from the shaping block, the punching rod punches a hole in the lamp tube bracket and is inserted into the shaping mold, thereby realizing the shaping and punching processing of the lamp tube bracket. After completion, the lower template moves downward, the punching rod withdraws from the shaping mold, and the pressing plate moves downward and leaves the lamp tube bracket.

[0010] As a further improvement of the above technical solution, the top side of the pressing plate is connected with a second guide post, and the top of the second guide post is slidably connected to the first upper mold. The second guide post on the top side of the pressing plate and the first upper mold form a sliding connection limit in the up and down direction. When the pressing plate moves up and down, the horizontal deviation of the pressing plate can be effectively reduced, making the pressing plate move more smoothly, thereby improving the quality of punching and shaping.

[0011] As a further improvement of the above technical solution, the present invention also includes an upper punching mechanism, which is located between the feeding mechanism and the punching and shaping mechanism, and includes processing units located on the left and right sides of the conveying device, and the processing units include a second base that can be close to or away from the conveying surface, a second upper mold and a second lower mold arranged in the second base, a forming block is provided on the side of the second lower mold facing the conveying surface, and a punching knife is provided on the position of the second upper mold facing the forming block, and the second upper mold can move up and down in the second base. When the lamp tube holder enters the conveying surface, the conveying surface first drives the lamp tube holder through the upper punching mechanism, and punches the top side of the end of the lamp tube holder in the upper punching mechanism. Specifically, the second bases in the two processing units on the left and right sides are respectively close to the conveying surface, so that the forming blocks located on the left and right sides of the lamp tube holder respectively enter the two ends of the lamp tube holder to position the lamp tube holder left and right, and the second upper mold is close to the second lower mold, so that the punching knife of the second upper mold is pressed toward the lamp tube holder, and the lamp tube holder is punched and cooperated with the forming block to complete the punching process on the top side of the end of the lamp tube holder. Then the second upper mold is moved up and reset, and the two second bases are moved away from each other, so that the two forming blocks are out of the two ends of the lamp tube holder, and the lamp tube holder can continue to be transferred by the conveying surface.

[0012] As a further improvement of the above technical solution, the conveying device includes two belt conveyors spaced apart in the left-right direction, the two belt conveyors respectively form the conveying surface, and a transmission shaft is connected between the two belt conveyors. The two belt conveyors respectively have a rotatable conveyor belt, and the two are synchronously connected by the transmission shaft, and the two rotatable conveyor belts are used to form two conveying surfaces for conveying the lamp holder, and by ensuring that the two conveying surfaces move synchronously, the lamp holder is placed on the two conveying surfaces for conveying, so that the lamp holder can be smoothly moved and conveyed.

[0013] As a further improvement of the above technical solution, the feeding mechanism includes a feeding lifting drive located between the two belt conveyors, and the feeding lifting drive is connected to the feeding rack. The feeding lifting drive can provide a driving force for the feeding rack to move in the up and down directions, and the feeding rack for feeding the lamp tube bracket can be placed between the two belt conveyors. Before the lamp tube bracket is loaded, the feeding lifting drive drives the feeding rack to move to the top of the stroke, at which time the lamp tube bracket can be fed into the upper rack, and then the feeding lifting drive drives the feeding rack to move to the bottom of the stroke, and the lamp tube bracket is placed on the conveying surfaces on both sides, so as to realize stable feeding of the lamp tube bracket, and then the feeding lifting drive moves up and resets.

[0014] As a further improvement of the above technical solution, the feeding rack is surrounded by a feeding trough facing upwards. The lamp tube bracket can be directly fed into the feeding trough from the previous station, and the feeding trough limits it. When the feeding rack moves down to place the lamp tube bracket on the conveying surface, it effectively prevents the lamp tube bracket from falling, thereby improving the stability of feeding the lamp tube bracket.

[0015] As a further improvement of the above technical solution, the present invention also includes a transfer mechanism, the transfer mechanism includes a transfer translation drive and a transfer gripper, the transfer translation drive is connected to the transfer gripper, and the transfer translation drive can drive the transfer gripper to move left and right to approach or move away from the loading rack. When loading the lamp tube holder to the loading rack, the transfer translation drive drives the transfer gripper to move synchronously with the lamp tube holder, the transfer gripper clamps the lamp tube holder, and assists the lamp tube holder in loading into the loading rack. When the loading rack is loaded into place, the transfer gripper releases the lamp tube holder, and the transfer translation drive returns to reset in the direction away from the loading rack, so that the lamp tube holder can be accurately delivered to the loading rack, which is particularly suitable for the case where the lamp tube holder is pushed into the loading rack by an external device.

[0025] Reference Figure 1 and Figure 2The lamp tube bracket forming line includes a conveying device, a feeding mechanism and a punching and shaping mechanism. The conveying device has a conveying surface extending in the front-back direction; the feeding mechanism is located on the conveying upstream side of the conveying device, and the feeding mechanism has a feeding frame 210 that can move downward to approach or upward to move away from the conveying surface; the punching and shaping mechanism includes working units located on the left and right sides of the conveying device, and the working units include a first base 310, a first upper mold 320 and a first lower mold arranged in the first base 310, and the first base 310 can move in the direction of approaching or moving away from the conveying surface. Of course, the first base 31 0 is connected to the first translation drive, which drives the first base 310 to move left and right. The first translation drive has various structural forms. For example, the first translation drive can adopt a cylinder, an electric screw or a hydraulic cylinder. A shaping die 321 is provided on the side of the first upper die 320 facing the conveying surface. The first lower die is provided with a shaping block 331 and a punching rod 332. The first upper die 320 and the first lower die can be close to each other, so that the shaping block 331 is against the shaping die 321, and the punching rod 332 is upwardly penetrated into the shaping block 331 and the shaping die 321.

[0026] As can be seen from the above, the lamp tube bracket that needs to be punched is sent to the conveying surface of the conveying device, and the conveying surface moves, driving the lamp tube bracket to move to the punching and shaping mechanism. At this time, the first base 310 in the two working units on the left and right sides respectively approaches the conveying surface, so that the shaping molds 321 located on the left and right sides of the lamp tube bracket respectively enter the two ends of the lamp tube bracket to position the lamp tube bracket left and right. The first lower mold approaches the first upper mold 320, so that the shaping block 331 of the first lower mold abuts against the lamp tube bracket, and the lamp tube bracket is pressed against the shaping mold 321 to flatten the part of the lamp tube bracket that is deformed due to punching. At the same time, the punching rod 332 in the first lower mold also moves up relative to the shaping block 331 and passes through the lamp tube bracket to punch the lamp tube bracket. The bottom side of the bracket is pressed against the bottom side of the shaping die 321, which effectively prevents the punching rod 332 from causing the surface of the lamp tube bracket to be pulled and deformed when punching the lamp tube bracket, thereby improving the punching processing quality of the lamp tube bracket. After completion, the first upper mold 320 and the first lower mold are separated from each other, the punching rod 332 withdraws from the shaping block 331 and the lamp tube bracket, and the first base 310 and the second base 610 move away from each other, so that the two ends of the lamp tube bracket respectively withdraw from the shaping die 321. At this time, the lamp tube bracket falls onto the conveying surface and is continued to be transferred to the next workstation by the conveying surface. In this way, when punching the lamp tube bracket, the end position of the lamp tube bracket can be flattened and shaped at the same time, and the pulling deformation of the position near the punching hole during the punching process is reduced, thereby improving the quality and efficiency of the punching processing of the lamp tube bracket.

[0027] When the lamp tube holder moves into position with the conveying surface, the conveying surface movement can be stopped so that the lamp tube holder is aligned with the punching and shaping mechanism. In order to improve the accuracy of the movement of the lamp tube holder, a structure for limiting the position of the lamp tube holder after it is moved into position can also be set on the conveying device. Specifically, the present invention also includes a first material blocking mechanism, which includes a first material blocking drive and a first material blocking member 400. The first material blocking drive is located beside the conveying surface. The first material blocking drive is transmission-connected to the first material blocking member 400. The first material blocking drive can drive the first material blocking member 400 to protrude upward or be retracted downward into the conveying surface. The first material blocking drive provides driving force for the first material blocking member 400 to move up and down, and its structural forms are various. For example, the first material blocking drive can adopt a cylinder, an electric screw or a hydraulic cylinder. Before the lamp tube holder moves into position with the conveying surface, the first material blocking drive drives the first material blocking member 400 to extend upward from the conveying surface to block the movement of the lamp tube holder, thereby ensuring the accuracy of the transfer of the lamp tube holder on the conveying surface and improving the accuracy of the alignment of the lamp tube holder and the molding die 321. After the punching process of the lamp tube holder is completed, the first material blocking drive drives the first material blocking member 400 downward to below the conveying surface, and the lamp tube holder can continue to move on the conveying surface.

[0028] Furthermore, in order to strengthen the positioning of the lamp tube bracket after it is transferred into place, the present invention also includes a first pressing mechanism, which includes a first pressing drive 510 and a first pressing block 520. The first pressing drive 510 is located above the conveying device, and the first pressing drive 510 is transmission-connected to the first pressing block 520. The first pressing block 520 and the molding die 321 are opposite to each other in the left-right direction, and the first pressing drive 510 can drive the first pressing block 520 to move up and down. The first pressing drive 510 can provide a driving force for the first pressing block 520 to move in the up and down directions. There are various structural forms. For example, the first pressing drive 510 can adopt a cylinder, an electric screw or a hydraulic cylinder. When the lamp tube holder moves into place with the conveying surface, the first pressing drive 510 drives the first pressing block 520 to move downward, and the first pressing block 520 is used to press the lamp tube holder against the conveying device, so as to further position the lamp tube holder. At this time, the first bases 310 on the left and right sides of the lamp tube holder are close to each other, ensuring that the two molding molds 321 can respectively enter the two ends of the lamp tube holder, and when the lamp tube holder is punched and shaped, the stability of the position of the lamp tube holder can also be ensured. After the processing of the lamp tube holder is completed, the first pressing drive 510 drives the first pressing block 520 to move upward and reset.

[0029] In actual applications, when the first pressing drive 510 drives the first pressing block 520 to press down the lamp tube holder to position it, the lamp tube holder is pressed against the conveying device to position it. At this time, the point of force of the first pressing block 520 pressing down the lamp tube holder can be on the fixed structure of the conveying device itself, thereby preventing the conveying surface from being pressed down and deformed. In addition, a pallet can be installed on the fixed structure of the conveying device itself, and the height of the pallet can be gradually raised along the conveying direction of the conveying device. When the lamp tube holder moves with the conveying surface, it can gradually move to the pallet, and the height of the lamp tube holder can be raised by using the pallet to support it, and then the lamp tube holder is pressed down and positioned on the pallet by the first pressing block 520.

[0030] The first material blocking mechanism and the first material pressing mechanism can be arranged in two in the left and right directions respectively, so that during the transfer of the lamp tube holder, the lamp tube holder is blocked from both ends and pressed down to position the lamp tube holder at both ends.

[0031] In each working unit, the first lower mold includes a lower mold plate 333, a first guide column 334, a spring 335 and a pressing plate 336. The lower mold plate 333 can move up and down in the first base 310. Of course, a first lifting drive is provided on the first base 310. The first lifting drive is connected to the lower mold plate 333 and the lower mold plate 333 is driven by the first lifting drive to move up and down. There are many structural forms of the first lifting drive. For example, the first lifting drive can adopt a cylinder, an electric screw or a hydraulic cylinder. The pressing plate 336 is located above the lower mold plate 333. The first guide column 334 is connected to the bottom side of the pressing plate 336. The bottom of the first guide column 334 is slidably connected to the lower template 333, the spring 335 is connected between the pressure plate 336 and the lower template 333, the shaping block 331 is connected to the top side of the pressure plate 336, the punching rod 332 is connected to the top side of the lower template 333, and the top end of the punching rod 332 is inserted into the pressure plate 336. In actual applications, there are multiple first guide columns 334 and multiple springs 335, and the multiple first guide columns 334 and multiple springs 335 are evenly arranged between the pressure plate 336 and the lower template 333 to improve the connection stability between the pressure plate 336 and the lower template 333. The pressing plate 336 is limited by the sliding of the first guide column 334 and the lower mold plate 333, and the spring 335 provides support for the pressing plate 336. At this time, the pressing plate 336 and the lower mold plate 333 form a whole, and the whole is moved upward to approach the first upper mold 320. The pressing plate 336 first contacts the first upper mold 320. At this time, the shaping block 331 on the top side of the pressing plate 336 presses against the bottom side of the lamp bracket. As the lower mold plate 333 gradually moves upward, the spring 335 is gradually compressed. The shaping block 331 gradually increases the pressure on the lamp tube bracket to flatten and shape the deformed position on the lamp tube bracket. When the punching rod 332 on the top side of the lower template 333 protrudes upward from the shaping block 331, the punching rod 332 punches a hole in the lamp tube bracket and inserts it into the shaping die 321, thereby realizing the shaping and punching processing of the lamp tube bracket. After completion, the lower template 333 moves downward, the punching rod 332 withdraws from the shaping die 321, and the pressing plate 336 moves downward to leave the lamp tube bracket.

[0032] Naturally, in order to allow the punching rod 332 to pass through the pressing plate 336, the shaping block 331 and be inserted into the shaping mold 321, a first through hole is provided on the pressing plate 336 opposite to the punching rod 332, the first through hole passes through the shaping block 331, and a second through hole is provided on the bottom side of the shaping mold 321 opposite to the first through hole.

[0033] In order to improve the stability of the movement of the pressing plate 336, in this embodiment, the top side of the pressing plate 336 is connected with a second guide post 337, and the top of the second guide post 337 is slidably connected to the first upper mold 320. In practical applications, there are multiple second guide posts 337, and multiple second guide posts 337 are evenly arranged between the layer plate and the first upper mold 320. The second guide post 337 on the top side of the pressing plate 336 and the first upper mold 320 form a sliding connection limit in the up and down direction. When the pressing plate 336 moves up and down, the horizontal deviation of the pressing plate 336 can be effectively reduced, so that the pressing plate 336 moves more smoothly, thereby improving the quality of punching and shaping.

[0034] For some lamp brackets, the top surface thereof needs to be punched. In this embodiment, the present invention further comprises an upper punching mechanism, which is located between the feeding mechanism and the punching and shaping mechanism. The upper punching mechanism comprises processing units located on the left and right sides of the conveying device, such as Figure 3 As shown, the processing unit includes a second base 610 that can be close to or away from the conveying surface, a second upper mold 620 and a second lower mold 630 arranged in the second base 610. Of course, the second base 610 is connected to the second translation drive, and the second translation drive drives the second base 610 to move left and right. The second translation drive has various structural forms. For example, the second translation drive can adopt a cylinder, an electric screw or a hydraulic cylinder. A forming block 631 is provided on the side of the second lower mold 630 facing the conveying surface, and a punching knife 621 is provided on the position of the second upper mold 620 facing the forming block 631. The second upper mold 620 can move up and down in the second base 610. When the lamp tube holder enters the conveying surface, the conveying surface first drives the lamp tube holder through the upper punching mechanism, and punches the top side of the end of the lamp tube holder in the upper punching mechanism. Specifically, the second base 610 in the two processing units on the left and right sides respectively approaches the conveying surface, so that the forming blocks 631 located on the left and right sides of the lamp tube holder respectively enter the two ends of the lamp tube holder to position the lamp tube holder left and right, and the second upper mold 620 approaches the second lower mold 630, so that the punching knife 621 of the second upper mold 620 is pressed toward the lamp tube holder, punches the lamp tube holder and cooperates with the forming block 631 to complete the punching process on the top side of the end of the lamp tube holder, and then the second upper mold 620 moves up and resets, and the two second bases 610 move away from each other, so that the two forming blocks 631 are out of the two ends of the lamp tube holder, and the lamp tube holder can continue to be transferred by the conveying surface.

[0035] In the processing unit, in order to drive the second upper mold 620 to move up and down in the second base 610, it is natural that a second lifting drive is provided on the second base 610. The second lifting drive is transmission-connected to the second upper mold 620, and the second upper mold 620 is driven by the second lifting drive to move downward toward the second lower mold 630 or upward away from the second upper mold 620. There are various structural forms of the second lifting drive. For example, the first material stop drive can adopt a cylinder, an electric screw or a hydraulic cylinder.

[0036] Similarly, when the lamp tube holder moves into position with the conveying surface, the movement of the conveying surface can be stopped so that the lamp tube holder is aligned with the upper punching mechanism. In order to improve the accuracy of the movement of the lamp tube holder, a structure for limiting the position of the lamp tube holder after it is moved into position can also be set on the conveying device. Specifically, the present invention also includes a second material blocking mechanism, the second material blocking mechanism includes a second material blocking drive and a second material blocking member, the second material blocking drive is located beside the conveying surface, the second material blocking drive is transmission-connected to the second material blocking member, and the second material blocking drive can drive the second material blocking member to protrude upward or be retracted downward into the conveying surface. The second material blocking drive provides driving force for the second material blocking member to move up and down, and its structural forms are various. For example, the second material blocking drive can adopt a cylinder, an electric screw or a hydraulic cylinder. Before the lamp tube holder moves into position with the conveying surface, the second material blocking drive drives the second material blocking member to extend upward from the conveying surface to block the movement of the lamp tube holder, thereby ensuring the accuracy of the transfer of the lamp tube holder on the conveying surface and improving the accuracy of the alignment of the lamp tube holder and the forming block 631. After the punching process on the top side of the lamp tube holder is completed, the second material blocking drive drives the second material blocking member downward to below the conveying surface, and the lamp tube holder can continue to move on the conveying surface.

[0037] Furthermore, in order to strengthen the positioning of the lamp tube bracket after it is moved into place, the present invention also includes a second pressing mechanism, the second pressing mechanism includes a second pressing drive and a second pressing block, the second pressing drive is located above the conveying device, the second pressing drive is transmission-connected to the second pressing block, the second pressing block and the forming block 631 are opposite to each other in the left-right direction, and the second pressing drive can drive the second pressing block to move up and down. The second pressing drive can provide a driving force for the second pressing block to move in the up and down directions. There are various structural forms. For example, the second pressing drive can adopt a cylinder, an electric screw or a hydraulic cylinder. When the lamp tube holder moves into place with the conveying surface, the second pressing drive drives the second pressing block to move downward, and the lamp tube holder is pressed against the conveying device by the second pressing block, so as to further position the lamp tube holder. At this time, the second bases 610 on the left and right sides of the lamp tube holder are close to each other, ensuring that the two forming blocks 631 can respectively enter the two ends of the lamp tube holder, and when the lamp tube holder is punched and shaped, the stability of the position of the lamp tube holder can also be ensured. After the processing of the lamp tube holder is completed, the second pressing drive drives the second pressing block to move upward and reset.

[0038] In actual applications, when the second pressing drive drives the second pressing block to press down the lamp tube holder to position it, the lamp tube holder is pressed against the conveying device to position it. At this time, the point of force of the second pressing block pressing down the lamp tube holder can be on the fixed structure of the conveying device itself, thereby preventing the conveying surface from being pressed down and deformed. In addition, a support plate can be installed on the fixed structure of the conveying device itself, and the height of the support plate can be gradually raised along the conveying direction of the conveying device. When the lamp tube holder moves with the conveying surface, it can gradually move to the support plate, and the height of the lamp tube holder can be raised by using the support plate, and then the lamp tube holder is pressed down and positioned on the support plate by the second pressing block.

[0039] The second material blocking mechanism and the second material pressing mechanism can be arranged in two in the left and right directions respectively, so that during the transfer of the lamp tube holder, the lamp tube holder is blocked from both ends and pressed down to position the lamp tube holder at both ends.

[0040] The conveying device is mainly used to provide driving force for conveying translation, and its structural forms include various types, such as roller conveyors, chain conveyors, etc. In this embodiment, the conveying device includes two belt conveyors 110 arranged at intervals in the left and right directions, and the two belt conveyors 110 respectively form the conveying surfaces, and a transmission shaft 120 is connected between the two belt conveyors 110. The two belt conveyors 110 respectively have rotatable conveyor belts, and the two are synchronously connected by the transmission shaft 120. The two rotatable conveyor belts are used to form two conveying surfaces for conveying the lamp holder, and by ensuring that the two conveying surfaces move synchronously, the lamp holder is placed on the two conveying surfaces for conveying, so that the lamp holder can be smoothly moved and conveyed.

[0041] The lamp holder that needs to be punched and shaped is placed in the loading rack 210. There are many ways to load the lamp from the loading rack 210 to the conveying surface. For example, the loading is achieved by flipping the loading rack 210 to pour out the lamp holder. In this embodiment, the loading mechanism includes a loading rack located between the two belt conveyors 110, and the loading lifting drive 220 is connected to the loading rack 210. The loading lifting drive 220 can provide a driving force for the loading rack 210 to move in the up and down direction. There are many structural forms. For example, the loading lifting drive 220 can use a cylinder, an electric screw or a hydraulic cylinder. A loading rack 210 for loading lamp tube brackets can be placed between two belt conveyors 110. Before loading the lamp tube brackets, the loading lifting drive 220 drives the loading rack 210 to move to the top of the stroke. At this time, the lamp tube brackets can be fed into the upper rack 210, and then the loading lifting drive 220 drives the loading rack 210 to move to the bottom of the stroke, and the lamp tube brackets are placed on the conveying surfaces on both sides to achieve stable loading of the lamp tube brackets, and then the loading lifting drive 220 moves up and resets.

[0042] Furthermore, the loading rack 210 is surrounded by a loading trough facing upwards. The lamp holder can be directly fed into the loading trough from the previous station, and the loading trough limits the position of the lamp holder. When the loading rack 210 moves down to place the lamp holder on the conveying surface, the lamp holder can be effectively prevented from falling, thereby improving the stability of loading the lamp holder.

[0043] In order to assist in the translation of the lamp tube holder onto the loading rack 210, in this embodiment, the present invention also includes a transfer mechanism, which includes a transfer translation drive 710 and a transfer clamp 720. The transfer translation drive 710 is transmission-connected to the transfer clamp 720. The transfer translation drive 710 can drive the transfer clamp 720 to move left and right to approach or move away from the loading rack 210. The transfer translation drive 710 is mainly used to provide a driving force for reciprocating translation in a linear direction. There are various structural forms. For example, the transfer translation drive 710 can adopt a cylinder, an electric screw or a hydraulic cylinder, etc., and the transfer clamp 720 is mainly used to realize the clamping and releasing of the lamp tube holder, and can adopt electric clamps, pneumatic clamps, etc. When loading the lamp tube holder onto the loading rack 210, the transfer translation drive 710 drives the transfer clamp 720 to move synchronously with the lamp tube holder, and the transfer clamp 720 clamps the lamp tube holder to assist in loading the lamp tube holder into the loading rack 210. When the loading rack 210 is loaded into place, the transfer clamp 720 releases the lamp tube holder, and the transfer translation drive 710 returns and resets in the direction away from the loading rack 210. This ensures that the lamp tube holder is accurately delivered to the loading rack 210, which is particularly suitable for situations where the lamp tube holder is pushed into the loading rack 210 by an external device.

Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
