Description

Technical Field

[0001] The utility model relates to the technical field of decorative lamp production, in particular to a positioning device for leather wire lamp injection equipment. Background Art

[0002] Leather wire lamp, also known as PVC soft wire lamp string, includes a wire, a leather wire wrapped around the wire, and a chip arranged in the leather wire and connected to the wire. The lamp head is integrated on the chip, thereby dividing the leather wire lamp into a leather wire part and a lamp head, wherein the lamp head is the part of the leather wire where the lamp head is located. In order to make the appearance of the leather wire lamp more beautiful, an injection molding mechanism is generally used to injection mold a decorative block on the lamp head of the leather wire lamp. The injection molding mechanism usually includes a fixed mold plate, a movable mold plate, a driving mechanism and an injection mechanism, etc. The fixed mold plate and the movable mold plate will be provided with a cavity groove according to the required shape of the decorative block. When it is necessary to perform injection molding on the leather wire lamp, the lamp head to be processed on the leather wire lamp is located in the cavity groove, and then the fixed mold plate and the movable mold plate are closed by the driving mechanism to form a complete cavity. The injection mechanism injects the molten plastic into the cavity, thereby realizing the installation of the decorative block on the leather wire lamp, that is, realizing the injection molding of the leather wire lamp.

[0003] There are usually multiple lamp heads on the leather wire lamp. When performing the injection molding process of the leather wire lamp, it is generally necessary to install the decorative blocks on the lamp heads one by one. The conveying mechanism conveys the leather wire lamp the same distance each time so that the lamp heads of the leather wire lamp can move one by one into the cavity groove of the injection molding mechanism. At present, the conveying mechanism generally adopts a roller to reel the leather wire lamp to realize the conveyance of the leather wire lamp. However, when curling, the leather wire lamp is easy to deviate from the circumferential direction of the roller, making the curling length too long, that is, the error of the conveying length is large, which makes it easy for the lamp head to deviate from the cavity groove of the injection molding mechanism and cause the decorative block to deviate from the specified installation position, which increases the unqualified rate of the injection molding process of the leather wire lamp, so it needs to be improved. Utility Model Content

[0004] In order to overcome the shortcoming of high failure rate of injection molding processing of leather-wire lamps in the prior art, the utility model provides a positioning device for leather-wire lamp injection molding equipment, which reduces the risk of the lamp head deviating from the cavity groove and causing the decorative block to deviate from the specified installation position, thereby reducing the failure rate of the injection molding processing of leather-wire lamps.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A positioning device for a leather wire lamp injection molding equipment comprises a workbench and an injection molding mechanism arranged on the workbench, the workbench is provided with a positioning mechanism and a conveying mechanism for conveying the leather wire lamp, the positioning mechanism, the injection molding mechanism and the conveying mechanism are arranged on the workbench in sequence, the positioning mechanism comprises a positioning piece, a first transverse driving assembly and a first lifting driving assembly, the first transverse driving assembly is used to drive the positioning piece to slide, the first transverse driving assembly is arranged on the first lifting driving assembly, the first lifting driving assembly is used to drive the first transverse driving assembly to rise and fall, the positioning piece is provided with a positioning groove, the leather wire portion width of the leather wire lamp is H, the diameter of the lamp head of the leather wire lamp is D1, the distance between the two side walls of the positioning groove is L, H<L<D1, the first lifting drive component can drive the positioning member to move to the first position, so that the leather wire part located before the lamp head to be processed is stuck in the positioning groove, the first transverse driving component can drive the positioning member to move from the first position to the second position, when the positioning member switches from the first position to the second position, the positioning member abuts against the deviated lamp head located before the lamp head to be processed, and slides with the leather wire lamp in the opposite direction to the conveying direction of the conveying mechanism, so that the deviated lamp head to be processed moves into the cavity groove of the injection molding mechanism.

[0007] In the above technical scheme, when this device is used to perform injection molding of a leather wire lamp, the conveying mechanism conveys the leather wire lamp so that the lamp head to be processed of the leather wire lamp moves to the injection molding mechanism. Before the injection molding mechanism processes the lamp head to be processed, the first lifting drive component drives the first transverse driving component to rise, that is, the positioning member rises, so that the leather wire portion located in front of the lamp head to be processed is stuck in the positioning groove, and then the first transverse driving component drives the positioning member to move transversely, that is, drives the positioning member to slide in the direction away from the workbench, so that the positioning member moves from the first position to the second position; if the lamp head to be processed does not deviate from the cavity groove of the injection molding mechanism, due to the leather wire The distance between each lamp head on the lamp is fixed, and each lamp head on the leather wire lamp is located at the specified position, that is, there is no deviation. When the positioning member is switched from the first position to the second position, the lamp head located before the lamp head to be processed will not hinder the sliding of the positioning member. When the positioning member is in the second position, the positioning member will contact with one of the lamp heads that has not deviated and is located before the lamp head to be processed; if the lamp head to be processed deviates from the cavity groove of the injection molding mechanism, the positioning member will contact with the deviated lamp head located before the lamp head to be processed when the positioning member is switched from the first position to the second position. Since the distance L between the two side groove walls of the positioning groove is smaller than the lamp head of the leather wire lamp The diameter D1 of the lamp head to be processed is 3400 mm / s, so the positioning piece will abut against the deviated lamp head located in front of the lamp head to be processed, that is, force is applied to the lamp head to make it slide together, so that the positioning piece slides with the leather wire lamp in the opposite direction of the conveying direction of the conveying mechanism, so that the lamp head located in front of the lamp head to be processed moves to the specified position. Even if it no longer deviates, since the distance between each lamp head on the leather wire lamp is fixed, the lamp head to be processed will no longer deviate from the specified position, that is, the deviated lamp head to be processed is moved into the cavity groove of the injection molding mechanism, thereby realizing the positioning of the leather wire lamp and reducing the deviation of the decorative block caused by the lamp head deviating from the cavity groove of the injection molding mechanism. The risk of the leather wire part being away from the designated installation position is reduced, thereby reducing the unqualified rate of the leather wire lamp injection molding processing; at the same time, the groove walls on both sides of the positioning groove will limit the distance that the leather wire part slides toward both sides, thereby preventing the leather wire lamp from sliding toward both sides too far to affect the abutment and cooperation between the positioning part and the lamp head, thereby improving the stability of the device; in addition, when the injection molding mechanism processes the lamp head to be processed, the first lifting drive assembly and the first transverse drive assembly drive the positioning part to reset, thereby canceling the snap-fitting cooperation between the leather wire part and the positioning groove, so that the conveying mechanism can subsequently convey the leather wire lamp, and the device can cyclically position and process, thereby realizing the injection molding processing of the leather wire lamp.

[0008] Preferably, a plurality of positioning grooves are provided, and the plurality of positioning grooves are arranged at intervals along the length direction of the positioning member.

[0009] In the structure, by providing a plurality of positioning grooves, the positioning member can be abutted and matched with the lamp heads on a plurality of leather-wire lamps at the same time, that is, the simultaneous positioning of a plurality of leather-wire lamps can be achieved, so that the device can process a plurality of leather-wire lamps at the same time, thus saving a large amount of overall time required for processing the leather-wire lamps and improving the processing efficiency of the device.

[0010] Preferably, the workbench is provided with a penetration plate, which is located on the side of the positioning mechanism away from the injection molding mechanism, and the penetration plate is provided with a plurality of penetration holes corresponding to the positioning grooves one by one, and the plurality of penetration holes are arranged at intervals along the length direction of the penetration plate, and the aperture of the penetration hole is D2, D1<D2.

[0011] In the structure, when the device is processing multiple leather wire lamps at the same time, the leather wire lamps are inserted into the corresponding penetration holes. The hole walls of the penetration holes can play a certain restrictive role in the moving path of the leather wire lamps, thereby reducing the risk of large errors in the transportation length of the leather wire lamps caused by the interlacing of the leather wire lamps, and improving the stability of the device.

[0012] Preferably, the workbench is slidably connected to two lifting rods, and the workbench is provided with a third lifting drive assembly for driving the lifting rods to rise and fall. The two lifting rods are located between the positioning mechanism and the conveying mechanism and are respectively located on both sides of the injection molding mechanism. The lifting rods are used to lift the leather wire lamp to make it separate from the cavity groove of the injection molding mechanism.

[0013] In the described structure, the decorative block generated by the injection molding mechanism when performing the injection molding process on the lamp head is easy to stick to the groove wall of the cavity groove, making it difficult for the lamp head to separate from the injection molding mechanism, which is not conducive to the subsequent transportation of the leather wire lamp; when the injection molding mechanism has completed the processing of the lamp head to be processed, before the transportation mechanism transports the leather wire lamp, the third lifting drive assembly drives the lifting rod to slide along the height direction of the workbench, so that the lifting rod lifts the leather wire parts located at the front and rear ends of the processed lamp head to be processed, so that after the processing of the lamp head to be processed is completed, it can rise and separate the decorative block from the groove wall of the cavity groove, even if the lamp head separates from the injection molding mechanism, the risk of affecting the transportation of the leather wire lamp due to the lamp head not being separated from the injection molding mechanism is reduced, and the stability of the device is improved.

[0014] Preferably, the workbench is provided with two guide plates, both of which are located between the positioning mechanism and the conveying mechanism and are respectively located on both sides of the injection molding mechanism, and the guide plates are provided with guide grooves corresponding to the positioning grooves.

[0015] In the structure, when the injection molding mechanism processes the leather wire lamp at the same time, the leather wire parts located at the front and rear ends of the lamp head to be processed are respectively plugged into two guide grooves, and the two guide grooves are respectively located on both sides of the injection molding mechanism. The cooperation between the leather wire lamp and the two guide grooves can limit the movement distance of the lamp head to be processed in the width direction of the workbench, preventing the lamp head to be processed from being displaced greatly in the width direction of the workbench and deviating from the cavity groove during the processing of the injection molding mechanism, reducing the risk of the lamp head deviating from the cavity groove and causing the decorative block to deviate from the designated installation position, and reducing the unqualified rate of the leather wire lamp injection molding. When the lifting rod drives the leather wire lamp to rise, the plug-in cooperation between the leather wire part and the guide groove can be cancelled, so that the conveying mechanism can subsequently convey the leather wire lamp.

[0016] Preferably, the conveying mechanism includes a clamping assembly for clamping the leather wire lamp and a second transverse driving assembly arranged on the workbench, the clamping assembly is arranged on the second transverse driving assembly, and the second transverse driving assembly is used to drive the clamping assembly to slide toward or away from the workbench.

[0017] In the described structure, compared with the conveying method of conveying the leather wire lamp directly by curling, the clamping component clamps the leather wire lamp so that the clamping component slides with the leather wire lamp, and the clamping component and the second transverse driving component can limit the conveying path of the leather wire lamp, thereby reducing the risk of the leather wire lamp deviating from the specified path and causing a large error in the conveying length, improving the accuracy of the conveying mechanism, and reducing the risk of the lamp head deviating from the specified position on the injection molding mechanism and causing the decorative block to deviate from the specified installation position, thereby reducing the unqualified rate of the leather wire lamp injection molding processing; at the same time, the second transverse driving component can drive the clamping component to slide in the direction close to or away from the workbench, that is, the clamping component can slide back and forth, so that each time the leather wire lamp is conveyed, the clamping component can repeat the previous movement path, saving the space required for the conveying mechanism.

[0018] Preferably, the clamping assembly includes a support frame, a first pressure plate and a second pressure plate which are arranged on the support frame and are opposite to each other, the support frame is arranged on the second transverse driving assembly, and the support frame is provided with a clamping driving member for driving the first pressure plate and the second pressure plate to be relatively close to or away from each other.

[0019] In the structure, the clamping assembly uses a first pressing plate and a second pressing plate to clamp the leather wire lamp, so that the clamping assembly can clamp leather wire lamps of different specifications and quantities, so that the conveying mechanism can be adapted to different usage requirements, thereby improving the practicality of the conveying mechanism.

[0020] Preferably, the conveying mechanism further comprises a second lifting drive member arranged on the second transverse driving assembly, the clamping assembly is arranged on the second lifting drive member, and the second lifting drive member is used to drive the clamping assembly to rise and fall.

[0021] In the structure, when the injection molding mechanism completes processing of the lamp head to be processed, the conveying mechanism conveys the leather wire lamp. Even if the clamping assembly clamps the leather wire lamp, before the second transverse driving assembly drives the clamping assembly to slide, the second lifting driving member drives the clamping assembly to rise along the height direction of the workbench, and the third lifting driving assembly drives the lifting rod to rise, so that while keeping the leather wire lamp as a whole rising, the leather wire lamp on the lifting rod is kept flush with the leather wire lamp on the clamping assembly to ensure that the leather wire lamp between the injection molding mechanism and the conveying mechanism is horizontally arranged when the leather wire lamp is conveyed, thereby reducing the risk of large errors in the conveying length of the leather wire lamp and improving the accuracy of the conveying mechanism.

[0022] Preferably, the workbench is provided with a cleaning device for cleaning residual material in the injection molding mechanism.

[0023] In the structure, when the injection molding mechanism completes processing of a lamp head to be processed, the cleaning device is used to clean the residual material in the injection molding mechanism before processing another lamp head, so as to prevent the residual material from affecting subsequent processing and reduce the unqualified processing rate.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. Reduce the risk of the lamp head deviating from the cavity groove and causing the decorative block to deviate from the designated installation position, and reduce the unqualified rate of the injection molding processing of the leather wire lamp;

[0026] 2. The positioning groove prevents the leather wire lamp from sliding too far to both sides to affect the abutment and cooperation between the positioning piece and the lamp head, thus improving the stability of the device;

[0027] 3. The clamping assembly and the second transverse drive assembly are used to transport the leather wire lamp, which reduces the risk of large errors in the attempted conveying length due to the leather wire lamp deviating from the specified path, improves the accuracy of the conveying mechanism, and reduces the unqualified rate of the leather wire lamp injection processing;

[0028] 4. The risk of affecting the delivery of the leather wire lamp due to the lamp head not being separated from the injection molding mechanism is reduced, and the stability of the device is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Embodiment 1

[0043] Reference Figure 1 , Figure 2 and Figure 3 A positioning device for a leather wire lamp injection equipment comprises a workbench 1, an injection molding mechanism 2 mounted on the workbench 1, a positioning mechanism 3 and a conveying mechanism 4 for conveying a leather wire lamp 5 are mounted on the workbench 1, and the positioning mechanism 3, the injection molding mechanism 2 and the conveying mechanism 4 are sequentially mounted on the workbench 1. The positioning mechanism 3 comprises a positioning member 31, a first transverse driving assembly 32 and a first lifting driving assembly 33, the first transverse driving assembly 32 is used to drive the positioning member 31 to slide, the first transverse driving assembly 32 is mounted on the first lifting driving assembly 33, and the first lifting driving assembly 33 is used to drive the first transverse driving assembly 32 to rise and fall.

[0044] Reference Figure 3 and Figure 4The positioning member 31 is provided with a positioning groove 312, the width of the leather wire portion 52 of the leather wire lamp 5 is H, the diameter of the lamp head 51 of the leather wire lamp 5 is D1, the distance between the two side groove walls of the positioning groove 312 is L, H<L<D1, the first lifting drive component 33 can drive the positioning member 31 to move to the first position, so that the leather wire portion 52 located before the lamp head 51 to be processed is inserted into the positioning groove 312, and the first transverse driving component 32 can drive the positioning member 31 to move from the first position to the second position. When the positioning member 31 switches from the first position to the second position, the positioning member 31 abuts against the deviated lamp head 51 located before the lamp head 51 to be processed, and drives the leather wire lamp 5 to slide in the opposite direction of the conveying direction of the conveying mechanism 4, so that the deviated lamp head 51 to be processed moves to the cavity groove 21 of the injection molding mechanism 2.

[0045] Reference Figure 3 and Figure 4 The leather wire lamp 5 includes a lamp head 51 and a leather wire part 52. The lamp head 51 is the part of the leather wire where the lamp head is located, and the leather wire part 52 is the other part of the leather wire.

[0046] Reference Figure 1 and Figure 2 , take the height direction of the workbench 1 as the direction of the Z axis, the length direction of the workbench 1 as the direction of the X axis, and the width of the workbench 1 as the direction of the Y axis, and establish a coordinate system with the X axis, Y axis, and Z axis, wherein the positive direction of the Z axis is up, the negative direction of the Z axis is down, the positive and reverse directions of the X axis are forward, and the negative direction of the X axis is backward, wherein the conveying direction of the leather wire lamp 5 is the negative direction of the X axis, and the positioning mechanism 3, the injection molding mechanism 2, and the conveying mechanism 4 are arranged in sequence along the conveying direction of the leather wire lamp 5.

[0047] According to a positioning device of a leather wire lamp injection molding equipment according to the present embodiment, when the device is used for injection molding of the leather wire lamp 5, the conveying mechanism 4 conveys the leather wire lamp 5 so that the lamp head 51 to be processed of the leather wire lamp 5 moves to the injection molding mechanism 2, and before the injection molding mechanism 2 processes the lamp head 51 to be processed, the first lifting drive component 33 drives the first transverse driving component 32 to rise, that is, the positioning member 31 rises, so that the leather wire part 52 located before the lamp head 51 to be processed is stuck in the positioning groove 312, and then the first transverse driving component 32 drives the positioning member 31 to move transversely, that is, drives the positioning member 31 to slide in the direction away from the workbench 1, so that the positioning member 31 moves from the first position to the second position; if the lamp head 51 to be processed does not deviate from the injection molding mechanism 2 The cavity groove 21 of the injection molding mechanism 2 is used as the molding tool 2. Since the distance between each lamp head 51 on the leather wire lamp 5 is fixed, each lamp head 51 on the leather wire lamp 5 is located at the specified position, that is, there is no deviation. When the positioning member 31 is switched from the first position to the second position, the lamp head 51 located before the lamp head 51 to be processed will not hinder the sliding of the positioning member 31. When the positioning member 31 is located at the second position, the positioning member 31 will contact with one of the lamp heads 51 that has not deviated and is located before the lamp head 51 to be processed; if the lamp head 51 to be processed deviates from the cavity groove 21 of the injection molding mechanism 2, when the positioning member 31 is switched from the first position to the second position, the positioning member 31 will contact with the deviated lamp head 51 that is located before the lamp head 51 to be processed. Due to the distance between the two side groove walls of the positioning groove 312 The distance L is smaller than the diameter D1 of the lamp head 51 of the leather wire lamp 5, so the positioning member 31 will abut against the deviated lamp head 51 located before the lamp head 51 to be processed, that is, force is applied to the lamp head 51 to make it slide together, so that the positioning member 31 slides with the leather wire lamp 5 in the opposite direction of the conveying direction of the conveying mechanism 4, so that the lamp head 51 located before the lamp head 51 to be processed moves to the specified position, even if it no longer deviates, since the distance between each lamp head 51 on the leather wire lamp 5 is fixed, the lamp head 51 to be processed will no longer deviate from the specified position, that is, the deviated lamp head 51 to be processed is moved into the cavity groove 21 of the injection molding mechanism 2, thereby realizing the positioning of the leather wire lamp 5 and reducing the lamp head 51 deviating from the cavity groove 21 of the injection molding mechanism 2. There is a risk that the decorative block deviates from the specified installation position, thereby reducing the unqualified rate of the injection molding of the leather wire lamp 5; at the same time, the groove walls on both sides of the positioning groove 312 will limit the distance that the leather wire part 52 slides toward both sides, thereby preventing the leather wire lamp 5 from sliding too far toward both sides to affect the abutment and cooperation between the positioning member 31 and the lamp head 51, thereby improving the stability of the device; in addition, when the injection molding mechanism 2 processes the lamp head 51 to be processed, the first lifting drive assembly 33 and the first transverse drive assembly 32 drive the positioning member 31 to reset, thereby canceling the snap-fitting between the leather wire part 52 and the positioning groove 312, so that the conveying mechanism 4 can subsequently convey the leather wire lamp 5, so that the device can cyclically position and process, thereby realizing the injection molding of multiple lamp heads 51 on the leather wire lamp 5.

[0048] Reference Figure 3 The positioning member 31 adopts a positioning plate 311 , and a positioning groove 312 is provided on the positioning plate 311 .

[0049] Reference Figure 3 The first lifting drive assembly 33 includes a mounting frame 331 and a first lifting cylinder 332. The first transverse driving assembly 32 includes a transverse frame 321 and a first transverse cylinder 322. The transverse frame 321 is slidably connected to the mounting frame 331. The mounting frame 331 is fixedly connected to the workbench 1. The first lifting cylinder 332 is fixedly connected to the mounting frame 331. One end of the piston rod of the first lifting cylinder 332 is fixedly connected to the transverse frame 321, so that the first lifting cylinder 332 drives the transverse frame 321 to move the first lifting cylinder 332 ... The moving frame 321 slides along the height direction of the workbench 1, i.e., the Z-axis direction, so that the traverse frame 321 is lifted and lowered; the positioning plate 311 is slidably connected to the traverse frame 321, and the first traverse cylinder 322 is fixedly connected to the traverse frame 321. One end of the piston rod of the first traverse cylinder 322 is fixedly connected to the positioning member 31, so that the first traverse cylinder 322 can drive the positioning plate 311 to slide in the direction close to or away from the workbench 1, i.e., slide along the X-axis direction, so that the positioning plate 311 moves horizontally. When it is necessary to move the positioning plate 311 to the first position, the piston rod of the first lifting cylinder 332 is extended, so that the traverse frame 321 rises, i.e., slides in the positive direction of the Z-axis, and the positioning plate 311 is installed on the traverse frame 321, so that the positioning member 31 rises, thereby moving the positioning member 31 to the first position. When it is necessary to switch the positioning member 31 from the first position to the second position, the piston rod of the first transverse cylinder 322 contracts, causing the positioning member 31 to slide away from the workbench 1, i.e., slide along the positive direction of the X-axis, thereby realizing the switching of the positioning member 31 between the first position and the second position.

[0050] Reference Figure 3 and Figure 5 Preferably, the mounting frame 331 is installed with a first displacement sensor, and the transverse frame 321 is fixedly connected with the first displacement block 3211. The first displacement sensor is used to detect the distance between itself and the first displacement block 3211 in the height direction of the workbench 1, that is, the Z-axis direction. When the distance between the first displacement sensor and the first displacement block 3211 reaches a specified value, the first displacement sensor feeds back information to the control system. The control system controls the first lifting cylinder 332 according to the feedback information to suspend the driving of the transverse frame 321 by the first lifting cylinder 332, so as to control the sliding distance of the transverse frame 321, so that the first displacement sensor can be used to control the sliding distance of the positioning member 31 from the first position to the second position, so that the sliding distance of the positioning member 31 is more accurate. At the same time, different sliding distances can be set by the first displacement sensor, so that the device can be suitable for more different usage conditions, thereby improving the practicality of the device.

[0051] Reference Figure 3 and Figure 5 Preferably, the transverse frame 321 is installed with a second displacement sensor 3212, and the positioning member 31 is fixedly connected to the second displacement block 3111. The second displacement sensor 3212 is used to detect the distance between itself and the second displacement block 3111 in the length direction of the workbench 1, that is, the X-axis direction. When the distance between the second displacement sensor 3212 and the second displacement block 3111 reaches a specified value, the second displacement sensor 3212 feeds back information to the control system, so that the control system controls the first transverse cylinder 322 according to the feedback information to suspend the driving of the positioning member 31 by the first transverse cylinder 322, so as to control the sliding distance of the positioning member 31, so that the second displacement sensor 3212 can be used to control the sliding distance of the positioning member 31 from the first position to the second position, so that the sliding distance of the positioning member 31 is more accurate, and different sliding distances can be set by the first displacement sensor, so that the device can be suitable for more different usage conditions, thereby improving the practicality of the device.

[0052] Since the decorative block generated by the injection molding mechanism 2 when the lamp head 51 is injected is easy to stick to the groove wall of the cavity groove 21 of the injection molding mechanism 2, it is difficult for the lamp head 51 to be separated from the injection molding mechanism 2. Therefore, in order to prevent the lamp head 51 from being separated from the injection molding mechanism 2 and affecting the transportation of the leather wire lamp 5, refer to Figure 5 and Figure 6, the workbench 1 is slidably connected to two lifting rods 11, and the workbench 1 is installed with a third lifting drive assembly 12 for driving the lifting rods 11 to rise and fall. The two lifting rods 11 are located between the positioning mechanism 3 and the conveying mechanism 4, and are respectively located on both sides of the injection molding mechanism 2. The lifting rods 11 are used to lift the leather wire lamp 5 to make it separate from the cavity groove 21 of the injection molding mechanism 2. Exemplary: the third lifting drive assembly 12 includes a third lifting cylinder 121 and a connecting plate 122 fixedly connected to the workbench 1, and the connecting plate 122 is fixedly connected to one end of the piston rod of the third lifting cylinder 121, so that the third lifting cylinder 121 can drive the connecting plate 122 to slide along the height direction of the workbench 1, and one end of the two lifting rods 11 is respectively fixedly connected to the two ends of the connecting plate 122; when the injection molding mechanism 2 completes the processing of the lamp head 51 to be processed, before the conveying mechanism 4 conveys the leather wire lamp 5, the third lifting drive assembly 12 drives the lifting rod 11 along the height direction of the workbench 1 Lifting and sliding, that is, the piston rod of the third lifting cylinder 121 is extended, even if the connecting plate 122 rises, so that the two lifting rods 11 rise at the same time, wherein the leather wire lamp 5 is located above the two lifting rods 11, so that the lifting rods 11 lift the leather wire part 52 located at the front and rear ends of the processed lamp head 51, so that after the processing of the lamp head 51 is completed, it can rise and make the decorative block separate from the groove wall of the cavity groove 21, even if the lamp head 51 is separated from the injection molding mechanism 2, thereby reducing the risk of affecting the transportation of the leather wire lamp 5 due to the lamp head 51 not being separated from the injection molding mechanism 2, and improving the stability of the device.

[0053] Reference Figure 5 and Figure 6 In order to further reduce the unqualified rate of the injection molding of the leather wire lamp 5, the workbench 1 is fixedly connected with two guide plates 13, both of which are located between the positioning mechanism 3 and the conveying mechanism 4 and respectively located on both sides of the injection molding mechanism 2, and the guide plates 13 are provided with guide grooves 131 corresponding to the positioning grooves 312. When the injection molding mechanism 2 processes multiple leather wire lamps 5 at the same time, the leather wire parts 52 on both sides of the lamp head 51 on the injection molding mechanism 2 are respectively inserted into the two guide grooves 131, and the two guide grooves 131 are respectively located on both sides of the injection molding mechanism 2. Through the cooperation between the leather wire lamp 5 and the two guide grooves 131, the moving distance of the lamp head 51 on the injection molding mechanism 2 in the extension direction of the Y axis can be limited, which prevents the lamp head 51 from being displaced greatly in the extension direction of the Y axis during the processing of the injection molding mechanism 2, causing the lamp head 51 to deviate from the specified position, reducing the risk of the lamp head 51 deviating from the specified position on the injection molding mechanism 2 and causing the decorative block to deviate from the specified installation position, thereby reducing the unqualified rate of the injection molding of the leather wire lamp 5. When the lifting rod 11 raises the leather wire lamp 5 , the plug-in fit between the leather wire portion 52 and the guide groove 131 can be cancelled, so that the conveying mechanism 4 can subsequently convey the leather wire lamp 5 .

[0054] Reference Figure 1 and Figure 2 In order to reduce the unqualified rate of processing, the workbench 1 is equipped with a cleaning device 14 for cleaning the residual material in the injection molding mechanism 2. The cleaning device 14 adopts a conventional cleaning device 14, exemplarily: the cleaning device 14 includes a cleaning frame, a clamping mechanism for clamping the residual material and a driving mechanism, the cleaning frame is fixedly connected to the workbench 1, the clamping mechanism is slidably connected to the cleaning frame, and the driving mechanism is used to drive the clamp to slide in a direction close to or away from the injection molding mechanism 2. After the injection molding mechanism 2 completes the processing of one of the lamp heads 51, the cleaning device is used to clean the residual material in the injection molding mechanism 2 before processing the other lamp head 51, that is, the driving mechanism drives the clamping mechanism to slide in a direction close to or away from the injection molding mechanism 2, so as to clamp out the residual material in the injection molding mechanism 2, prevent the residual material from affecting the subsequent processing, and reduce the unqualified rate of processing. Other structures are not described here.

[0055] In this embodiment, the injection molding mechanism 2 adopts a conventional injection molding mechanism 2, and the injection molding mechanism 2 includes a fixed mold plate, a movable mold plate, a driving assembly and an injection assembly. The fixed mold plate and the movable mold plate are provided with a cavity groove 21 according to the required shape of the decorative block. When it is necessary to perform injection molding on the leather wire lamp 5, the lamp head 51 to be processed on the leather wire lamp 5 is located in the cavity groove 21, that is, at a designated position on the injection molding mechanism 2. Thereafter, the fixed mold plate and the movable mold plate are closed by the driving assembly to form a complete cavity. The injection assembly injects the molten plastic into the cavity to realize the installation of the decorative block on the leather wire lamp 5. Other structures are not repeated here.

[0056] Embodiment 2

[0057] Based on Example 1,

[0058] Reference Figure 7 A plurality of positioning grooves 312 are provided, and the plurality of positioning grooves 312 are evenly arranged along the length direction of the positioning plate 311 , that is, along the Y-axis direction.

[0059] According to a positioning device of a leather wire lamp injection equipment of the present embodiment, a plurality of positioning grooves 312 are provided so that a positioning plate 311 can be simultaneously abutted and matched with the lamp heads 51 on a plurality of leather wire lamps 5, that is, a plurality of leather wire lamps 5 can be simultaneously positioned, so that the device can process a plurality of leather wire lamps 5 at the same time, thereby saving a large amount of overall time required for processing the leather wire lamps 5 and improving the processing efficiency of the device.

[0060] Reference Figure 7In order to prevent the leather wire lamps 5 from being staggered, the workbench 1 is fixedly connected with a penetration plate 15. The penetration plate 15 is located on the side of the positioning mechanism 3 away from the injection molding mechanism 2. The penetration plate 15 is provided with a plurality of penetration holes 151 corresponding to the positioning grooves 312. The plurality of penetration holes 151 are evenly arranged along the length direction of the penetration plate 15, i.e., the Y-axis direction. The aperture of the penetration hole 151 is D2, and D1 is less than D2. When the device processes a plurality of leather wire lamps 5 at the same time, each leather wire lamp 5 is inserted into the corresponding penetration hole 151. The hole wall of the penetration hole 151 can limit the sliding path of the leather wire lamp 5 to a certain extent, thereby reducing the risk of large errors in the conveying length of the leather wire lamp 5 caused by the staggering of the leather wire lamps 5 and improving the stability of the device.

[0061] Embodiment 3

[0062] Based on Example 1,

[0063] Reference Figure 8 and Fig. 9 The conveying mechanism 4 includes a clamping assembly 41 for clamping the leather wire lamp 5 and a second transverse driving assembly 42 installed on the workbench 1. The clamping assembly 41 is installed on the second transverse driving assembly 42. The second transverse driving assembly 42 is used to drive the clamping assembly 41 to slide toward or away from the workbench 1.

[0064] According to a positioning device of a leather wire lamp injection equipment of the present embodiment, the second transverse driving component 42 enables the clamping component 41 to have an initial position and an end position. When the conveying mechanism 4 is required to convey the leather wire lamp 5, the clamping component 41 is located at the initial position, and the clamping component 41 clamps the leather wire lamp 5. Then the second transverse driving component 42 drives the clamping component 41 away from the workbench 1, and the part of the leather wire lamp 5 clamped by the clamping component 41 slides along with the clamping component 41, thereby realizing the conveyance of the leather wire lamp 5. When the clamping component 41 After sliding to the end position, the second transverse driving component 42 no longer drives the clamping component 41 to slide, thereby realizing the transportation of a specific length of the leather wire lamp 5; then the clamping component 41 cancels the clamping of the leather wire lamp 5, so that the leather wire lamp 5 can be slid by the positioning member 31 so that the positioning mechanism 3 can position and adjust the leather wire lamp 5; at the same time, before the conveying mechanism 4 is needed to transport the leather wire lamp 5 next time, the second transverse driving component 42 drives the clamping component 41 to slide in the direction close to the workbench 1, so that the clamping component 41 is reset to the initial position. Compared with the prior art in which the leather wire lamp 5 is directly rolled up by a reel to realize the transportation of the leather wire lamp 5, the clamping component 41 clamps the leather wire lamp 5 so that the clamping component 41 slides with the leather wire lamp 5. During the movement of the clamping component 41 from the initial position to the final position, the clamped part of the leather wire lamp 5 can be kept sliding along the extension direction parallel to the X-axis, that is, it has a certain limiting effect on the transportation path of the leather wire lamp 5, reduces the risk of the leather wire lamp 5 deviating from the specified path and causing a large error in the transportation length, improves the accuracy of the transportation mechanism 4, and reduces the lamp head 51. The risk of the decorative block deviating from the designated position on the injection molding mechanism 2 causing it to deviate from the designated installation position reduces the unqualified rate of the injection molding of the leather wire lamp 5; at the same time, the second transverse driving component 42 can drive the clamping component 41 to slide in the direction close to or away from the workbench 1, so that the clamping component 41 can slide back and forth, that is, each time the conveying mechanism 4 conveys the leather wire lamp 5, the clamping component 41 can be reset to the initial position, so that each time the leather wire lamp 5 is conveyed, the clamping component 41 can repeat the previous movement path, thereby saving the space required for the conveying mechanism 4.

[0065] Reference Figure 8 and Fig. 9In order to enable the second transverse driving assembly 42 to drive the clamping assembly 41 to slide in a direction close to or away from the workbench 1, that is, to slide in the extension direction of the X-axis, the second transverse driving assembly 42 includes a sliding frame 421, a fixed frame 422 slidingly connected to the sliding frame 421, a transmission screw 423 rotatably connected to the sliding frame 421 and a driving motor 424 for driving the transmission screw 423 to rotate, the output end of the driving motor 424 is connected to one end of the transmission screw 423, the clamping assembly 41 is installed on the fixed frame 422, the fixed frame 422 is slidingly connected to the sliding frame 421, the fixed frame 422 is fixedly connected with a sliding block, the sliding block is threadedly connected to the transmission screw 423, the sliding frame 421 is fixedly connected with a guide rail, the guide rail and the transmission screw 423 are arranged along the extension direction of the X-axis, and the fixed frame 422 is fixedly connected with a guide block plugged in with the guide rail. When it is necessary to drive the clamping assembly 41 to slide, the driving motor 424 drives the transmission screw 423 to rotate, and the fixed block on the fixed frame 422 is threadedly connected to the transmission screw 423, and the guide rail and the guide block are plugged into and cooperated to limit the rotation of the fixed frame 422, so that the fixed frame 422 slides along the extension direction of the transmission screw 423, even if the fixed frame 422 slides in the direction of the X-axis, the clamping assembly 41 is installed on the fixed frame 422, so that the clamping assembly 41 slides in the direction of the X-axis, wherein the driving motor 424 can drive the transmission screw 423 to rotate in the opposite direction, so that the clamping assembly 41 can slide back and forth, that is, the second transverse driving assembly 42 can drive the clamping assembly 41 to slide in the direction close to or away from the workbench 1.

[0066] Reference Figure 8 and Fig. 9In order to achieve the clamping of the leather wire lamp 5 by the clamping assembly 41, the clamping assembly 41 includes a support frame 411 and a first pressure plate 412 and a second pressure plate 413 installed on the support frame 411 and arranged oppositely. The support frame 411 is installed with a clamping drive 4111 for driving the first pressure plate 412 and the second pressure plate 413 to move closer to or away from each other. Exemplary: the first pressure plate 412 is slidably connected to the support frame 411, a part of the support frame 411 serves as the second pressure plate 413, the support frame 411 is installed on the fixed frame 422, the clamping drive 4111 is a clamping cylinder fixedly connected to the support frame 411, and one end of the piston rod of the clamping cylinder is fixedly connected to the side of the first pressure plate 412 away from the second pressure plate 413, so that the clamping cylinder drives the first pressure plate 412 to slide in the direction of approaching or moving away from the second pressure plate 413. When clamping the leather wire lamp 5, the leather wire lamp 5 is located between the first pressure plate 412 and the second pressure plate 413, and the piston rod of the clamping cylinder is extended to make the first pressure plate 412 slide toward the second pressure plate 413, so that the first pressure plate 412 and the second pressure plate 413 are relatively close to each other, until the leather wire lamp 5 is tightly abutted against the two sides of the first pressure plate 412 and the second pressure plate 413 facing each other, that is, the leather wire lamp 5 is clamped by the first pressure plate 412 and the second pressure plate 413, wherein the first pressure plate 412 and the second pressure plate 413 enable the clamping assembly 41 to clamp leather wire lamps 5 of different specifications and quantities, so that the conveying mechanism 4 can be adapted to different usage requirements, thereby improving the practicability of the conveying mechanism 4.

[0067] In another embodiment, the second pressing plate 413 is fixedly connected to the support frame 411;

[0068] Reference Figure 8 and Fig. 9In order to further improve the conveying accuracy of the conveying mechanism 4, the conveying mechanism 4 also includes a second lifting drive member 43, which is used to drive the clamping assembly 41 to slide along the height direction of the workbench 1. Exemplary: the second lifting drive member 43 is a second lifting cylinder 431, the second lifting cylinder 431 is fixedly connected to the fixing frame 422, and the support frame 411 is fixedly connected to one end of the piston rod of the second lifting cylinder 431, so that the second lifting cylinder 431 can drive the support frame 411 to slide along the height direction of the workbench 1, that is, slide along the extension direction of the Z axis. When the injection molding mechanism 2 completes the processing of one of the lamp heads 51, the conveying mechanism 4 conveys the leather wire lamp 5, and even if the clamping component 41 clamps the leather wire lamp 5, before the second transverse driving component 42 drives the clamping component 41 to slide, the piston rod of the second lifting cylinder 431 extends, so that the support frame 411 rises along the height direction of the workbench 1. Even if the support frame 41 slides in the positive direction of the Z-axis, the clamping component 41 as a whole rises along the height direction of the workbench 1. Since the clamping component 41 clamps the leather wire lamp 5, the leather wire lamp 5 rises with the clamping component 41, and the third lifting driving component 12 drives the lifting rod 11 to rise, so that while keeping the leather wire lamp 5 as a whole rising, the leather wire lamp 5 on the lifting rod 11 is kept flush with the leather wire lamp 5 on the clamping component 41, so as to ensure that the leather wire lamp 5 between the injection molding mechanism 2 and the conveying mechanism 4 is arranged horizontally when the leather wire lamp 5 is conveyed, thereby reducing the risk of large errors in the conveying length of the leather wire lamp 5 and improving the accuracy of the conveying mechanism 4.

[0069] Reference Figure 8 and Fig. 9 Preferably, the fixing frame 422 is fixedly connected with a third displacement sensor 4221, and the supporting frame 411 is fixedly connected with a third displacement block 4112. The third displacement sensor 4221 is used to detect the distance between itself and the third displacement block 4112 in the height direction of the workbench 1, that is, the Z-axis direction. When the distance between the third displacement sensor 4221 and the third displacement block 4112 reaches a specified value, the third displacement sensor 4221 feeds back information to the control system. The control system can control the second lifting cylinder 431 according to the feedback information to suspend the driving of the second lifting cylinder 431 on the supporting frame 411, so as to control the rising height of the clamping assembly 41, so that the rising height of the clamping assembly 41 is more accurate.
