Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dispensing, in particular to a connector processing joint dispensing machine. BACKGROUND

[0002] In the field of electronic devices, automobile wiring harnesses, communication equipment, etc., a large number of connectors are used to connect different devices. In the process of processing each connector, the joints of the connectors and the wires need to be sealed. The sealing of the connector joints is usually achieved by dispensing machines to coat glue quantitatively. The existing connector joint dispensing machine generally consists of a dispensing mechanism, a feeding device and a positioning clamp. The core function is to accurately coat glue (such as epoxy resin, silicone, etc.) on the connection part of the joint and the wire. The main functions include sealing against moisture, fixing terminals, insulation protection and corrosion prevention, to avoid the intrusion of external moisture, dust or chemicals into the joint, prevent signal transmission failure, circuit short circuit or metal terminal oxidation caused by poor contact, etc.

[0003] At present, the mainstream dispensing method is single-head single-side dispensing, that is, a single dispensing head is used to coat glue on one side of the connector joint. Some devices need to be combined with manual or mechanical overturning mechanisms to complete double-side dispensing to meet the full-sealing requirement. The traditional device only fixes the end of the joint by the clamp, and lacks effective constraint on the middle section of the wire. When the wire is affected by its own gravity, overturning dispensing or external vibration, it is easy to bend or deviate, so that the connection part of the joint and the wire cannot maintain the preset dispensing gap, which may cause local accumulation, overflow or incomplete coverage of the glue during coating, resulting in uneven thickness of the sealing layer, forming a leakage channel, reducing the waterproof and dustproof performance of the joint, and possibly causing internal circuit failure after long-term use. In addition, the existing device adopts single-side dispensing mode, and needs to realize joint double-side coating by mechanical rotation. During the overturning process, the connector is easy to be pulled or twisted, causing internal wire breakage or insulation layer damage. At the same time, the process cycle of single-side dispensing is long, which seriously restricts the batch production efficiency. SUMMARY

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] The embodiments provided by the present application will be described in detail below:

[0034] As Figures 1 to 4 and Figures 6 to 9As shown, a connector processing joint dispensing machine, comprising a work platform 1 and a plurality of connecting lines 2, the upper surface of the work platform 1 is fixedly connected with a moving platform 11, the moving platform 11 is slidably connected with a moving frame 12, the moving frame 12 is inserted with a clamp plate 13, the plurality of connecting lines 2 are clamped by the clamp plate 13, the side wall of the work platform 1 is fixedly connected with a gantry 14 through bolts, the gantry 14 is fixedly connected with a lifting module 15, the lifting module 15 is slidably connected with a lifting block 16, the lifting block 16 is provided with a dispensing assembly;

[0035] It should be noted that the connecting line 2 is composed of a line body and a joint, the clamp plate 13 is a special clamp for fixing the joint of the connecting line 2, and the clamp plate 13 can clamp and fix the connecting line 2; the moving platform 11 is provided with a linear driving device for driving the moving frame 12 to slide horizontally on the moving platform 11, which is a prior art and has a wide range of options, for example, an electric push rod directly pushes the moving frame 12, or a sliding lead screw is added at the bottom of the moving frame 12 to control the movement, and different driving devices can be selected according to actual needs, so no further structural limitation is made in the specification and the drawings; the outside of the work platform 1 is provided with an ultraviolet lamp device corresponding to the position of the moving platform 11, which also belongs to a variety of shapes of prior art, so it is not shown in the figure, and the ultraviolet lamp device is used for irradiation and curing of the dispensing connecting line 2; the lifting module 15 is composed of a frame and an electric screw rod, and the electric screw rod of the lifting module 15 is threadedly connected with the lifting block 16, and the lifting block 16 moves up and down by rotating the screw rod.

[0036] The dispensing assembly comprises a connecting plate 41 fixedly connected to the lifting block 16, a small motor 42 fixedly connected to each end of the side of the connecting plate 41 close to the lifting block 16, the output shafts of the two small motors 42 penetrating through the connecting plate 41, an electric telescopic rod two 43 fixedly connected to one end of the output shaft of each small motor 42 penetrating through the connecting plate 41, a fixed rod 44 fixedly connected to the telescopic shaft of each electric telescopic rod two 43, a fixed frame 45 fixedly connected to the top of each fixed rod 44 through bolts, a pressing plate 46 fixedly connected to the top of each fixed frame 45 through bolts, a through hole linearly arranged between each fixed frame 45 and the adjacent pressing plate 46, a dispensing device 47 slidably connected in the through hole between the two fixed frames 45 and the two pressing plates 46, the dispensing device 47 being symmetrically arranged with the connecting line 2 as the center line, a connecting pipe 48 fixedly connected to the top of each dispensing device 47, an electric telescopic rod three 49 fixedly connected to each fixed frame 45, and the telescopic end of each electric telescopic rod three 49 being fixedly connected with the adjacent dispensing device 47.

[0037] It needs to be explained that the fixed frame 45 is composed of a frame body and an inclined plate, the inclined plate is used to keep the glue dispenser 47 inclined when it is on the fixed frame 45, that is, it can make the glue dispenser 47 inclined to the joint of the connecting wire 2; the glue dispenser 47 is composed of a plurality of glue dispensing heads, a plurality of glue dispensing pipes and a hollow plate, the glue dispensing head of the glue dispenser 47 is detachably installed in the glue dispensing pipe of the glue dispenser 47, that is, the glue dispensing head of the glue dispenser 47 in the prior art is screwed on the glue dispensing pipe of the glue dispenser 47; the plurality of glue dispensing pipes of the glue dispenser 47 are fixedly connected with the hollow plate of the glue dispenser 47, the hollow plate of the glue dispenser 47 is communicated with the connecting pipe 48, the connecting pipe 48 shown in the drawings is only a structure for facilitating drawing, the connecting pipe 48 is a flexible soft pipe rather than a hard pipe, and the connecting pipe 48 is externally connected with a conveying pump, that is, the conveying pump can pump glue into the inside of the glue dispenser 47 through the connecting pipe 48, and then pump it out by the glue dispensing head; the hollow plate of the glue dispenser 47 is provided with a protruding part on one side of the electric telescopic rod three 49, and the telescopic end of the electric telescopic rod three 49 is fixedly connected with the protruding part of the hollow plate of the glue dispenser 47.

[0038] Specifically, before the connecting wire 2 is glued, the lifting block 16 is at the highest position, and then the lifting block 16 drives the small motor 42 to the highest position through the connecting plate 41, and the output shaft of the small motor 42 drives the electric telescopic rod two 43 to rotate, and the electric telescopic rod two 43 drives the fixed frame 45 and the pressing plate 46 to rotate at the same time through the fixed rod 44, at this time, the glue dispenser 47 is in a vertical state, or the glue dispensing head of the glue dispenser 47 is in an outward state, which is used to facilitate the worker to take and place the clamp plate 13 on the moving frame 12.

[0039] In the process of dispensing the connecting line 2, the worker needs to first take the clamp plate 13 off the moving frame 12, then place the connecting line 2 joint that needs to be sealed and dispensed in the clamp plate 13 after opening the clamp plate 13, then fix the joint of the connecting line 2 after closing the clamp plate 13, and then reinsert the clamp plate 13 into the moving frame 12. At this time, the worker can start the device, wherein the coded controller controls the electric screw rod of the lifting module 15 to drive the lifting block 16 to move downward in the frame of the lifting module 15, at this time the lifting block 16 will drive the small motor 42 to move downward through the connecting plate 41, then the controller controls the small motor 42 to rotate, the small motor 42 drives the fixed rod 44 to rotate through the electric telescopic rod two 43, the fixed rod 44 drives the dispenser 47 to rotate through the fixed frame 45 and the pressing plate 46, at this time the dispensing head of the dispenser 47 rotates close to the joint of the connecting line 2 clamped by the clamp plate 13. The dispensing head is located beside the joint of the connecting line 2, that is, the dispensing head of the dispenser 47 is not completely aligned with the part of the connecting line 2 that needs to be dispensed, at this time the controller controls the conveying pump to convey the glue into the hollow plate of the dispenser 47 through the connecting pipe 48, the glue in the hollow plate of the dispenser 47 will be divided into several dispensing pipes, then the glue will be squeezed out by the dispensing heads. In the process of squeezing out the glue, the controller also controls the telescopic shaft of the electric telescopic rod two 43 to extend and retract, the telescopic shaft of the electric telescopic rod two 43 drives the fixed frame 45 and the pressing plate 46 to move horizontally by a short distance synchronously through the fixed rod 44, the fixed frame 45 and the pressing plate 46 can drive the dispenser 47 to move horizontally synchronously, the horizontal movement of the dispenser 47 can move the dispensing heads on it from one side of the joint of the connecting line 2 to the other side, that is, the movement of the dispenser 47 can cover a single larger joint of the connecting line 2, and the dispensing heads of the dispenser 47 can simultaneously dispense the joints of multiple connecting lines 2. In addition, since the dispenser 47 is provided with two batches and is symmetrical about the connecting line 2, the dispensing heads on the two dispensers 47 are on both sides of the joint of the connecting line 2, so that the dispensing heads on the two dispensers 47 can simultaneously dispense both sides of the joint of the connecting line 2. Compared with the single-sided dispensing operation of the existing connecting line 2 joint dispenser, simultaneous dispensing of both sides of the connecting line 2 by the two dispensers 47 can improve the dispensing efficiency, and there is no need to flip the connecting line 2 for dispensing, thereby directly avoiding the situation of shaking the connecting line 2 during flipping, and further improving the dispensing efficiency.

[0040] It should be noted that after the dispensing is completed by the dispenser 47, at this time the controller controls the conveying pump to stop conveying glue into the connecting pipe 48, and at the same time the controller controls the electric screw rod of the lifting module 15 to drive the lifting block 16 to move upward for a short distance, the lifting block 16 drives the small motor 42 to move upward for a short distance through the connecting plate 41, the small motor 42 drives the electric telescopic rod two 43 to drive the fixed rod 44 to move upward for a short distance synchronously through the output shaft, and the fixed rod 44 drives the dispenser 47 to move upward for a short distance through the fixing frame 45 and the pressing plate 46 at the same time, at this time the dispenser 47 can move upward away from the joint position of the connecting line 2 which is dispensed. Then the output shaft of the small motor 42 is controlled to rotate, the output shaft of the small motor 42 drives the fixed rod 44 to rotate through the electric telescopic rod two 43, the fixed rod 44 drives the dispensing head of the dispenser 47 to rotate outward through the fixing frame 45 and the pressing plate 46 at the same time, so that the dispensing head of the dispenser 47 is away from the joint of the connecting line 2 which is dispensed, and then the electric screw rod of the lifting module 15 is controlled again to drive the lifting block 16 to continue to move upward, so that the dispenser 47 moves to the initial vertical state or the dispensing head of the dispenser 47 is in the outward state, so that the connecting line 2 is not blocked. At this time the linear drive device of the moving platform 11 is controlled by the controller to drive the moving frame 12 to move towards the ultraviolet lamp, and at the same time the ultraviolet lamp irradiates and cures the glue at the joint dispensing position of the connecting line 2, and finally the workman can take away the clamp plate 13 from the moving frame 12, so that the dispensing and sealing operation of a batch of connecting lines 2 can be completed.

[0041] In addition, the short distance movement in the above can be replaced by controlling the extension of the telescopic shaft of the electric telescopic rod three 49, and after the telescopic shaft of the electric telescopic rod three 49 is extended, the dispenser 47 is driven to move away from the connecting line 2, that is, the two dispensers 47 move to both sides, at this time the dispensing pipe of the dispenser 47 slides in the through hole of the fixing frame 45 and the pressing plate 46, at this time the dispensing head of the dispenser 47 is away from the joint position of the connecting line 2 which is dispensed. For some connecting lines 2 with protruding structures, the collision between the dispensing head of the dispenser 47 and the joint protruding structure of the connecting line 2 can be avoided when the dispensing is moved, so that the dispensing head of the dispenser 47 is prevented from being damaged, and at the same time the joint of the connecting line 2 is prevented from being damaged.

[0042] It should be noted that when only the above structure is used for dispensing operation, an additional component is needed to fix the end of the wire head which is not fixed on the clamp plate 13, so that the connecting line 2 as a whole remains in a vertical state, preventing the other end of the connecting line 2 from sagging and hindering the normal dispensing process during the dispensing process.

[0043] Based on this problem, the present scheme further adds a holding assembly for fixing the connecting line 2.

[0044] As Figure 2 , Figure 4And Figure 5 As shown in the figure, the clamp plate 13 is provided with a retaining assembly for retaining the vertical state of the connecting line 2, the retaining assembly comprises two fixed seats 31 fixedly connected to the clamp plate 13 by bolts, two shaft rods 32 are fixedly connected to each of the two fixed seats 31, an electric telescopic rod one 33 is rotatably connected to each of the shaft rods 32, two torsion springs one 34 are sleeved on each of the shaft rods 32, the two ends of each of the torsion springs one 34 are fixedly connected with the outer wall of an adjacent electric telescopic rod one 33 and the fixed seat 31 respectively, a connecting rod 35 is fixedly connected to the top end of the telescopic shaft of each of the electric telescopic rod one 33, two connecting rods 35 located on the same side are a group, and there are two groups in total, as shown in the figure, Figure 2 As shown in the figure, the two groups of connecting rods 35 are symmetrically arranged about the clamp plate 13, a rotating rod 36 is rotatably connected between the two connecting rods 35 of each group, there are two rotating rods 36, the two ends of the two rotating rods 36 pass through the connecting rods 35 to the two sides, a torsion spring two 37 is sleeved on the surface of each end of the two rotating rods 36, each of the torsion springs two 37 abuts against an adjacent connecting rod 35 and the end of the rotating rod 36 respectively, a hollow rod 38 is fixedly connected to the outer surface of each of the two rotating rods 36 between the two connecting rods 35, and a stage 39 is fixedly connected to each of the two connecting rods 35 of each group.

[0045] It should be noted that the outer surface of the hollow rod 38 is wrapped with a layer of rubber skin for anti-skid effect when the hollow rod 38 contacts with the connecting line 2, the two stages 39 extend to the two sides respectively and are bent upwards for storing the line body part of the connecting line 2 which is not clamped.

[0046] Specifically, initially, under the action of torsion spring 34, two groups of connecting rods 35 are in a state of approaching each other through electric telescopic rod 33, at this time, hollow rods 38 are in a state of mutual resistance, after the clamp plate 13 clamping the connecting line 2 is inserted on the moving frame 12, the staff needs to hold the connecting line 2 which is not clamped, then pull one of the shelves 39, at this time, the shelf 39 will drive the electric telescopic rod 33 to rotate around the shaft 32 to the direction away from the other side of the electric telescopic rod 33. When the electric telescopic rod 33 rotates, the torsion spring 34 will be elastically tightened, then the unclamped connecting line 2 is placed between the two hollow rods 38, at this time, the staff needs to lay the connecting line 2 on the surface of the hollow rod 38 at the same height as the hollow rod 38, it is not necessary to lay completely and uniformly, that is, the connecting line 2 will not be stacked. At this time, the shelf 39 is loosened, and under the elastic resetting action of the torsion spring 34, the electric telescopic rod 33 reversely rotates around the shaft 32, at this time, the electric telescopic rod 33 will drive the rotating rod 36 to clamp the connecting line 2 through the connecting rod 35, at this time, the part of the connecting line 2 above the two hollow rods 38 can be placed on any one of the shelves 39. Based on the above dispensing process, after starting the device, the controller will control the synchronous extension of the telescopic shaft of all electric telescopic rods 33, the telescopic shaft of the electric telescopic rod 33 will drive the two rotating rods 36 to move upward synchronously through all connecting rods 35, the two rotating rods 36 will drive the two hollow rods 38 to move upward synchronously, because the surface of the hollow rod 38 has a layer of rubber skin, when the hollow rod 38 moves upward, the hollow rod 38 will roll on the connecting line 2, that is, the hollow rod 38 will rotate, the rotation of the hollow rod 38 will drive the rotating rod 36 to rotate on the connecting rod 35, the rotation of the rotating rod 36 will make the torsion spring 37 elastically tighten, at this time, under the elastic resetting action of the torsion spring 37, the hollow rod 38 will be pushed by the rotating rod 36 to generate a reverse rotating force, that is, at this time, the two hollow rods 38 will pull the connecting line 2 upward, the part of the connecting line 2 below the two hollow rods 38 will be straightened, through the pulling of the connecting line 2 by the hollow rod 38, the connecting line 2 will keep vertical, avoiding the bending of the connecting line 2 which causes the connecting line 2 to be unable to keep effective dispensing space with the connector, further ensuring that the glue will not overflow when dispensing on both sides of the connector of the connecting line 2 simultaneously, also preventing the connecting line 2 from affecting the movement trajectory of the dispensing head of the dispenser 47, avoiding the connecting line 2 from being contaminated with glue, while keeping the connecting line 2 vertical, it can also prevent the wire harness from being knotted during dispensing.

[0047] It needs to be explained that the line body of the connecting line 2 is not kept vertical with its joint, that is, the line body of the connecting line 2 is inclined compared with its joint, and the space on the inclined side of the line body of the connecting line 2 is smaller. Since the glue is synchronously extruded, the amount of glue is the same. If the glue space is small, the glue in the small space will overflow. If the line body of the connecting line 2 is inclined, the movement trajectory of the glue dispenser 47 will be affected. If there is residual glue on the glue dispensing head of the glue dispenser 47, the glue will adhere to the line body of the connecting line 2 during the movement of the glue dispenser 47, causing the line body to be contaminated.

[0048] In addition, the torsion spring two 37 is mainly used to prevent hard pulling of the line body of the connecting line 2 from causing the joint of the connecting line 2 to be separated from the clamp plate 13 or the line body of the connecting line 2 to be loose. The two ends of the torsion spring two 37 are movably connected with the connecting rod 35 and the rotating rod 36. When the torsion force borne is less than the friction force borne by the two ends, that is, the pulling force of the hollow rod 38 pulling the connecting line 2 is within the preset range, the torsion spring two 37 normally provides the torsion moment of the hollow rod 38 in the opposite direction. When the torsion force borne is greater than the friction force borne by the two ends, that is, the pulling force of the hollow rod 38 pulling the connecting line 2 is too large, and the joint of the connecting line 2 is pulled off, the two ends of the torsion spring two 37 slide, and the hollow rod 38 is no longer provided with a greater torsion moment, thereby avoiding damage to the connecting line 2 when pulling the line body of the connecting line 2.

[0049] Further, for connecting lines 2 of different lengths, the worker can manually control the extension or contraction of the extension shaft of the electric telescopic rod one 33 through the controller. For example, for longer connecting lines 2, the extension shaft of the electric telescopic rod one 33 can be controlled to extend, and the extension shaft of the electric telescopic rod one 33 will drive the connecting rod 35 to move upward, and the connecting rod 35 will drive the hollow rod 38 to move upward synchronously through the rotating rod 36. For shorter connecting lines 2, the extension shaft of the electric telescopic rod one 33 can be controlled to contract.

[0050] As shown in Figure 3 The top of the clamp plate 13 is fixedly connected with a vibrator 5 on both sides.

[0051] Specifically, after the above-mentioned dispensing of the connecting line 2 is completed, that is, when the dispenser 47 is away from the joint position of the connecting line 2 which is dispensed, at this time the controller controls the vibrator 5 to start. After the vibrator 5 starts, it will vibrate. The vibration force generated by the vibrator 5 will be transmitted to the connecting line 2 through the clamp plate 13, and then the connecting line 2 will vibrate synchronously. By vibrating the connecting line 2 through the vibrator 5, the unhardened state of the glue on the joint of the connecting line 2 can be promoted to flow. The glue will enter the gap between the joint of the connecting line 2 and the wire body, so that the glue can form a more uniform protective film after solidification, avoiding the situation that the glue is excessively accumulated or incompletely covered on the joint of the connecting line 2, and improving the quality of the dispensing and sealing of the joint of the connecting line 2.

[0052] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
