Description

Technical Field

[0001] The invention relates to the technical field of lamp detection, and in particular to a hardness detection device for an impact-resistant LED lamp housing. Background Art

[0002] The hardness test of lamp housing is an important part to ensure the quality and safety of lamps. Since the materials of lamp housing are diverse, including metal (such as aluminum, steel, etc.), plastic, glass, etc., the hardness test method will also vary depending on the material.

[0003] The impact hardness test of the lamp shell on the assembly line is mostly carried out by fixing the lamp shell on an intermittently moving conveyor belt. When the lamp shell arrives at the test point, the conveyor belt stops, and the lamp shell stays for a fixed time before continuing to run. During the stay period, the cylinder or hydraulic cylinder drives the punch to impact the lamp shell. If the lamp shell is deformed or cracked, it is considered unqualified.

[0004] However, manual determination of test results on the assembly line requires a lot of manpower, has limited test efficiency, and high test costs. In addition, lamps made of some materials may break and splash during testing, which may injure workers. Therefore, it does not meet existing needs. We propose a hardness testing device for impact-resistant LED lamp housings. Summary of the invention

[0025] The present invention has the following beneficial effects:

[0026] 1. The hardness detection device for the impact-resistant LED lamp shell can impact the lamp shell through the cooperation of the hydraulic cylinder and the impact head. Through the cooperation of the fixed sleeve, the pressure sleeve and the detection spring, when the impact head contacts the lamp shell, the detection spring absorbs the impact and is compressed. If the hardness of the lamp shell is qualified, the detection spring remains compressed. If the hardness of the lamp shell is unqualified, the lamp shell is squeezed and deformed or directly ruptured by the impact head. Through the cooperation of the conveyor belt and the limit mechanism, the lamp shell can be fixed on the track, so that the lamp shell will not be displaced during the movement and the impact detection process, thereby ensuring the smoothness of the detection process. Different from the prior art, this scheme installs a synchronization rod on the side of the fixed sleeve. Through the cooperation of the synchronization rod, the transmission plate and the through groove, different responses can be made to the detection results, making the streamlined detection more automated, reducing labor costs and improving detection efficiency.

[0027] 2. The hardness detection device for the impact-resistant LED lamp shell hinges the transmission plate and the reinforcement seat, and cooperates with the synchronization rod and the straight through groove and the arc through groove, so that when the detection fails, the synchronization rod enters the arc through groove from the straight through groove. Since the arc through groove is arc-shaped and the movement of the synchronization rod is vertical, the synchronization rod is squeezed with the arc through groove after entering the arc through groove, so that the transmission plate is displaced as a whole, and the trigger block is displaced by the impact of the trigger block and the transmission plate. Through the cooperation of the double-tooth rack, the fixed rack and the double gear, when the trigger block moves, the knock-down bar moves outward, thereby pushing the lamp shell that fails the detection into the defective product collection port, further reducing the amount of manual operation, further reducing the detection cost and improving the detection efficiency.

[0028] 3. The hardness testing device for the impact-resistant LED lamp housing is provided with a limit mechanism. When the lampshade positioning block reaches the testing point, the movable bolt will slide and fit with the connecting hook. When the lever is rotated upward, the cross bar will be driven to move upward, thereby causing the connecting hook to move upward. The lampshade positioning block, the rope and the movable bolt are driven. When the connecting hook hooks the movable bolt and moves upward, the lampshade positioning block will be pulled down by the rope, thereby causing the lampshade positioning block to be retracted into the track piece, thereby releasing the restriction on the lamp housing, and the knock-down bar can smoothly push the unqualified lamp housing into the track piece;

[0029] Moreover, a reducing-stroke bevel groove is provided between the arc-shaped groove and the straight-line groove, so that before the synchronization rod enters the arc-shaped groove, the output wheel shaft rubs against the reducing-stroke bevel groove and rotates, so that the triggering time of the cross bar is earlier than the triggering time of the trigger block, thereby ensuring that the lamp housing is unlocked earlier than the time when the lamp housing is pushed out, ensuring the logical reliability of the present invention, and making the operation of the device smoother.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1: This embodiment is intended to promote the solution of the problem that the manual determination of the test results in the assembly line requires a large amount of manpower, the test efficiency is limited, the test cost is high, and some materials of lamps may break and splash during the test, which may injure the staff. Please refer to Figure 1-9 A device for detecting the hardness of an impact-resistant LED lamp housing comprises an intermittently running conveyor belt 10 for transmitting the lamp housing, a housing 20 is arranged on the side of the conveyor belt 10, a hydraulic cylinder 210 is installed on the side of the housing 20, an impact head 220 for detecting the hardness of the lamp housing is arranged at the telescopic end of the hydraulic cylinder 210, the conveyor belt 10 comprises a crawler 110, the crawler 110 comprises a plurality of crawlers 111 hinged at the head and tail, a limiting mechanism 600 for placing and limiting the lamp housing is installed on the crawler 111, a fixing sleeve 230 is installed on the upper side of the impact head 220, a pressure sleeve 240 is installed at the bottom end of the telescopic end of the hydraulic cylinder 210, the pressure sleeve 240 is plugged and engaged with the fixing sleeve 230, and a detection spring 250 for detecting the impact resistance of the lamp housing is installed between the pressure sleeve 240 and the fixing sleeve 230.

[0042] In the specific setting, the conveyor belt 10 is set as an electric conveyor belt, and is set to automatically stop for a period of time when the product reaches the detection point. This intermittent conveyor belt is very common in existing industrial production and is a conventional technical means known to personnel in this field.

[0043] When the limiting mechanism 600 moves with the conveyor belt 10 to the bottom of the impact head 220, the conveyor belt 10 stops intermittently, and the hydraulic cylinder 210 drives the impact head 220 to hit the lamp housing; if the detection spring 250 is compressed and the lamp housing is intact, the test result is considered qualified; if the lamp housing is deformed or broken, the test result is considered unqualified.

[0044] A synchronization rod 260 is installed on the side of the fixed sleeve 230, and a reinforcement seat 310 is installed on the side of the casing 20. A transmission plate 320 is hinged in the middle of the reinforcement seat 310. A through slot 330 is opened on the transmission plate 320, and the synchronization rod 260 passes through the through slot 330. A torsion spring 311 is installed at the connection between the transmission plate 320 and the reinforcement seat 310.

[0045] The through groove 330 includes a straight through groove 331 and an arc through groove 332. The arc through groove 332 is connected below the straight through groove 331. The bottom end of the straight through groove 331 is on the same horizontal line as the detection point of the lamp housing.

[0046] In normal state, the synchronization rod 260 is located at the top of the straight groove 331; during detection, the synchronization rod 260 moves downward with the impact head 220, and when the detection is completed; the synchronization rod 260 stops at the bottom of the straight groove 331, and the detection result is qualified; the synchronization rod 260 enters the arc groove 332, and the detection result is unqualified.

[0047] In this embodiment: through the cooperation of the hydraulic cylinder 210 and the impact head 220, the lamp housing can be impacted. Through the cooperation of the fixing sleeve 230, the pressure sleeve 240 and the detection spring 250, when the impact head 220 contacts the lamp housing, the detection spring 250 absorbs the impact and is compressed. If the hardness of the lamp housing is qualified, the detection spring 250 remains compressed. If the hardness of the lamp housing is unqualified, the compression amount of the detection spring 250 will exceed a preset threshold value, which is set according to the hardness standard of a qualified lamp housing, so that the lamp housing is squeezed and deformed or directly ruptured by the impact head 220;

[0048] Through the cooperation of the conveyor belt 10 and the limiting mechanism 600, the lamp housing can be fixedly placed on the track piece 111, so that the lamp housing will not be displaced during the moving process and the impact detection process, thereby ensuring the smoothness of the detection process;

[0049] Different from the prior art, this solution installs a synchronization rod 260 on the side of the fixed sleeve 230. Through the cooperation of the synchronization rod 260, the transmission plate 320 and the groove 330, different responses can be made to the detection results, making the streamlined detection more automated, reducing labor costs and improving detection efficiency.

[0050] Embodiment 2: This embodiment aims to solve the problem that unqualified products need to be removed manually after testing, which is costly and inefficient. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 9 A defective product collection port 11 is provided on the conveyor belt 10, and a trigger block 410 and a knock-down bar 490 are slidably installed on the side of the casing 20. The trigger block 410 and the knock-down bar 490 are transmission-coordinated. When the synchronization rod 260 enters the arc-shaped groove 332, it pushes the transmission plate 320 to rotate, triggering the transmission plate 320 to hit the trigger block 410, and the knock-down bar 490 pushes the lamp housing that fails the inspection into the defective product collection port 11.

[0051] See Figure 3 A fixed rack 440 is fixedly installed on the side of the casing 20, and a double-tooth rack 450 is slidably arranged below the fixed rack 440. A connecting block 420 is installed on the side of the trigger block 410, and a double gear 430 is rotatably installed on the side of the connecting block 420. The double gear 430 is meshed with the double-tooth rack 450 and the fixed rack 440 at the same time. An output rack 470 is installed on the side of the knock-down bar 490, and a transmission gear 460 is rotatably installed inside the casing 20. The transmission gear 460 is meshed with the output rack 470 and the double-tooth rack 450 at the same time. A reset spring 480 for resetting is installed between the trigger block 410 and the casing 20.

[0052] When the trigger block 410 is moved by an external force, the double-tooth rack 450 will move along the direction of the fixed rack 440 through the transmission of the connecting block 420 and the double gear 430. Due to the rolling stroke of the double gear, the actual movement distance of the double-tooth rack will be greater than the movement distance of the trigger block. This amplified movement distance is transmitted to the output rack 470 through the transmission gear 460, which in turn drives the knock-down bar 490 to move, ensuring that the lamp housing is effectively pushed out within a limited space. When the trigger block is reset, the reset spring 480 will provide the necessary force to restore the trigger block 410 to its initial state.

[0053] In this embodiment, the transmission plate 320 is hinged to the reinforcement seat 310, and the synchronization rod 260 cooperates with the straight through groove 331 and the arc through groove 332, so that when the detection fails, the synchronization rod 260 enters the arc through groove 332 from the straight through groove 331. Since the arc through groove 332 is arc-shaped and the movement of the synchronization rod 260 is vertical, the synchronization rod 260 enters the arc through groove 332 and is squeezed with the arc through groove 332, so that the transmission plate 320 is displaced as a whole, and the trigger block 410 and the transmission plate 320 are connected. 0 is struck, causing the trigger block 410 to move. Through the cooperation of the double-tooth rack 450, the fixed rack 440 and the double gear 430, when the trigger block 410 moves, the double-tooth rack 450 will move in the same direction as the trigger block 410, and the double-tooth rack 450 moves a longer distance. Then, through the transmission of the double-tooth rack 450 and the output rack 470, the knock-down bar 490 moves outward, thereby pushing the lamp housing that fails the inspection into the defective product collection port 11, further reducing the amount of manual operation, further reducing the inspection cost and improving the inspection efficiency.

[0054] Embodiment 3: This embodiment is intended to promote the solution of the problem that the lamp housing is hindered when being pushed out due to the setting of the limiting mechanism 600. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 9 The limiting mechanism 600 includes a lampshade positioning block 610, a positioning outer ring 620 is provided on the outer ring at the bottom of the lampshade positioning block 610, a positioning center column 630 is provided at the bottom center of the positioning outer ring 620, the positioning outer ring 620 is slidably matched with the track piece 111, a slot 690 is provided on the track piece 111, the positioning center column 630 is plugged into the slot 690, and an unlocking spring 640 is installed on the outer side of the positioning center column 630.

[0055] The side of the track piece 111 is movably mounted with a movable bolt 660 for controlling the contact limit of the lampshade positioning block 610, the side of the housing 20 is movably mounted with a connecting hook 530 that movably cooperates with the movable bolt 660, the end of the synchronization rod 260 is rotatably mounted with an output wheel shaft 270, the output wheel shaft 270 is clearance-matched with the straight through groove 331, the end of the output wheel shaft 270 is fixedly mounted with a shaft end wheel 280, the side of the shaft end wheel 280 is mounted with a lever 290, and the connecting hook 530 is drivingly connected with the cross bar 510,

[0056] When the synchronization rod 260 enters the arc-shaped through groove 332 , the lever 290 moves the cross bar 510 , so that the lampshade positioning block 610 unlocks the lamp housing.

[0057] A rope 650 is installed at the bottom of the positioning center column 630, and the other end of the rope 650 is connected to the slot 690. A slider 670 is installed on the side of the slot 690. A slide groove 680 is opened inside the track piece 111, and the slider 670 slidably cooperates with the slide groove 680.

[0058] A vertical groove 550 is opened on the side of the housing 20, and the cross bar 510 is slidably installed in the vertical groove 550. A connecting rod 520 is vertically installed at the bottom of the cross bar 510. The bottom of the connecting rod 520 is connected to the connecting hook 530, and a pressure spring 540 is installed between the cross bar 510 and the vertical groove 550.

[0059] The shaft end wheel 280 and the cross bar 510 maintain clearance fit, and the cross bar 510 will not be triggered when the shaft end wheel 280 moves up and down.

[0060] See Fig. 9 A distance reducing bevel groove 333 is connected between the straight through groove 331 and the arc through groove 332 to ensure that the lamp housing is released earlier than it is pushed out. Originally, the output wheel shaft 270 will not rotate before entering the arc through groove 332, but the setting of the distance reducing bevel groove 333 allows the output wheel shaft 270 to rotate in advance, ensuring the accurate triggering time of the device mechanism and improving the reliability of the device.

[0061] In this embodiment: through the setting of the limiting mechanism 600, when the lampshade positioning block 610 arrives at the detection point, the movable bolt 660 will slide and fit with the connecting hook 530, and through the setting of the output wheel shaft 270, the shaft end wheel 280 and the lever 290, after the synchronization rod 260 enters the arc-shaped groove 332, the output wheel shaft 270 and the arc-shaped groove 332 rub and roll, so that the shaft end wheel 280 rotates, and when the lever 290 rotates upward, it will drive the cross bar 510 to move upward, thereby causing the connecting hook 530 to move upward, and the lampshade positioning block 610, the rope 650 and the movable bolt 660 are driven. When the connecting hook 530 hooks the movable bolt 660 and moves upward, the lampshade positioning block 610 will be pulled down by the rope 650, so that the lampshade positioning block 610 is retracted into the track 111, so that the lamp housing is released from restriction, and the knock-down bar 490 can smoothly push the unqualified lamp housing into the track 111.

[0062] Moreover, by setting a reducing-stroke bevel groove 333 between the arc-shaped groove 332 and the straight groove 331, the output wheel shaft 270 rubs against the reducing-stroke bevel groove 333 and rotates before the synchronization rod 260 enters the arc-shaped groove 332, so that the triggering time of the cross bar 510 is earlier than the triggering time of the trigger block 410, thereby ensuring that the lamp housing is unlocked earlier than the time when the lamp housing is pushed out, ensuring the logical reliability of the present invention, and making the device run more smoothly.

[0063] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
