[0002] There is a charger shell, such as Fig. 9 As shown, a groove is provided at the side end of the charger housing for the internal wire to extend outward from the housing. In order to fix the wire, a fixing plastic fastener is usually inserted into the groove to clamp the wire. In the process of assembling the plastic fastener to the charger housing, it is usually assembled manually, and the whole assembly process is inefficient. Summary of the invention

[0003] In order to improve the efficiency of assembling plastic fasteners, the present application provides a plastic fastener assembly machine.

[0004] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0005] The cam is a device for assembling plastic fasteners according to the present invention, wherein the cam is a device for assembling plastic fasteners and the cam is a device for assembling plastic fasteners according to the present invention. The cam is a device for assembling plastic fasteners according to the present invention, wherein the cam is a device for assembling plastic fasteners according to the present invention, wherein the cam is a device for assembling plastic fasteners according to the present invention, wherein the cam is a device for assembling plastic fasteners according to the present invention, wherein the cam is a device for assembling plastic fasteners according to the present invention, wherein the cam is a device for assembling plastic fasteners according to the present invention,

[0006] By adopting the above technical scheme, when the plastic fastener assembly machine is used, the plastic fasteners are gathered in the vibrating loading tray. As the vibrating loading tray works, the plastic fasteners are vibrated into the loading chute in turn, and the plastic fasteners are clamped and moved by claws that can move in three-coordinate directions until the plastic fasteners enter the material transfer base. The material transfer plate moves horizontally to move the plastic fasteners in the material feeding base horizontally out, and then the loading rod moves vertically and pushes the plastic fasteners through the loading table. At this time, the positioning fixture clamps the shell, and the plastic fasteners are directly clamped with the shell under the push of the loading rod, thereby completing the assembly of the shell and the plastic fasteners. This scheme enables the entire assembly process to be completed by the machine, which greatly improves the assembly efficiency.

[0007] Preferably, a conveying track is provided on the lower side of the frame, and a plurality of clamp bases are arranged on the conveying track for horizontal sliding in sequence, a plurality of the positioning clamps are arranged at the upper end of the clamp base along the sliding direction of the clamp base, and a plurality of the material transfer bases are arranged along the sliding direction of the clamp base and aligned with the positioning clamps.

[0008] By adopting the above technical solution, the conveying track conveys the fixture base horizontally in sequence, and multiple positioning fixtures are fixed on the fixture base at the same time. A shell can be clamped on each positioning fixture, and multiple material transfer bases are also provided. When assembling, the clamps clamp the plastic fasteners to the material transfer base in sequence, and then convey them synchronously through the material transfer plate and the loading rod, and finally assemble them. The entire assembly process can be carried out synchronously, so that multiple plastic fasteners can be assembled at the same time, thereby further improving the assembly efficiency.

[0009] Preferably, the frame includes a material transfer rack to which the material transfer base is fixed, a first through hole for a fastener to pass through is vertically opened in the middle of the material transfer base, a second through hole aligned with the first through hole and for the fastener to pass through is vertically opened on the material transfer rack, a third through hole aligned with the second through hole and for the fastener to be inserted and penetrated is vertically opened on the material transfer plate, a loading channel aligned with the third through hole and for the fastener to pass through is vertically opened on the loading platform, a support bar abutting against the lower end surface of the material transfer plate and covering the third through hole is provided on the lower side of the material transfer plate, the upper end surface of the support bar is flush with the upper end surface of the loading platform, and one end of the support bar abuts against the side end of the loading platform.

[0010] By adopting the above technical scheme, when assembling, the clamp inserts the plastic fastener into the first through hole of the material transfer base, and the plastic fastener slides directly into the second through hole along the first through hole. When the material transfer plate moves horizontally to the third through hole and is aligned with the second through hole, the plastic fastener enters the third through hole again and abuts against the upper end surface of the support bar. As the material transfer plate moves horizontally, the plastic fastener moves along with it. When it moves to the third through hole and is aligned with the loading channel, the loading rod can slide vertically and be inserted into the third through hole, thereby pushing the plastic fastener into the loading channel and finally assembling. This scheme makes the plastic fastener more accurate and more stable during the transmission process, reduces the occurrence of errors, reduces the assembly stop phenomenon caused by transmission errors, and further speeds up the assembly efficiency.

[0011] Preferably, the first through hole, the third through hole and the upper opening of the charging channel are in a flared shape.

[0012] By adopting the above technical solution, when the plastic fastener is moved to the material transfer base through the clamping jaws, in order to ensure that the plastic fastener can be accurately inserted, the upper end opening of the first through hole is set to a flared shape, making the insertion of the plastic fastener more convenient. Similarly, when the plastic fastener is inserted into the third through hole and the loading channel, the open-shaped upper opening can play the same role.

[0013] Preferably, a pushing rod is vertically slidably provided on the upper side of the material transfer rack and can penetrate into the first through hole, the second through hole and the third through hole in sequence.

[0014] By adopting the above technical solution, in order to ensure that the fastener can move in the first through hole, the second through hole and the third through hole, the width of the hole must be greater than the width of the plastic fastener. When the fastener is slightly tilted outward, the plastic fastener can easily get stuck in the first through hole or the second through hole. In this solution, a push rod is provided so that when the plastic fastener enters the first through hole, the push rod can be used to push the plastic fastener directly into the third through hole, thereby ensuring that the transmission of the plastic fastener is smoother and faster, thereby improving assembly efficiency.

[0015] Preferably, both side ends of the material transfer rack are provided with stoppers on both sides of the material transfer plate for the material transfer plate to slide and abut against.

[0016] By adopting the above technical scheme, when the material transfer plate moves, on the one hand, the third through hole on the material transfer plate should be aligned with the second through hole, and on the other hand, the third through hole should be aligned with the loading channel, so that the accuracy of the moving position of the material transfer plate determines whether the plastic fastener can be smoothly transferred. In this scheme, stop members are arranged on both side ends of the material transfer frame, so that the material transfer plate stops when it abuts against the stop members during movement, and the two groups of stop members correspond to the two moving ends of the material transfer plate, so that the material transfer plate can be accurately positioned and stopped, thereby making the plastic fastener more accurate and more stable during the transmission process.

[0017] Preferably, a pushing platform is vertically slidably provided on the lower side of the conveying track to push the fixture base to move vertically upward, a positioning block is provided at the corner of the lower end of the fixture base, and a positioning groove is provided on the upper end of the pushing platform for inserting the positioning block.

[0018] By adopting the above technical scheme, when the conveying track is conveying the clamp base, the clamp base may not be able to maintain a horizontal state and may be slightly tilted. At this time, when assembling the plastic fasteners, the plastic fastener assembly may be skewed, resulting in poor assembly quality. The clamp base is pushed vertically upward by the pushing table to make the clamp base separate from the conveying track, so that the clamp base maintains a relatively horizontal state before preparing for assembly, thereby ensuring the accuracy of subsequent assembly. At the same time, when assembling the plastic fasteners, the downward pressure of the loading rod will be relatively large. In this scheme, the clamp base is supported by the pushing table, so that the assembly process is more stable. At the same time, the pushing table remains in a horizontal position, and the position of the clamp base can also be made more accurate by the pushing table.

[0019] Preferably, both side ends of the positioning block are inclined, the positioning groove is flared, and both side walls of the positioning groove are parallel to both side end surfaces of the positioning block.

[0020] By adopting the above technical solution, the positioning block is set to be wedge-shaped, and the positioning groove is set to be a flared groove corresponding to the positioning block, so that when the pushing platform pushes the clamp base, the lower end of the positioning block is first inserted into the positioning groove, and then inserted along the inclined surface. When the pushing platform pushes the clamp base, even if the position of the clamp base is slightly offset, it can still be accurately pushed, which is more convenient.

[0021] Preferably, a fixing column abutting against the upper end surface of the shell is vertically arranged at the lower end of the frame on the upper side of the positioning fixture.

[0022] By adopting the above technical solution, when the loading rod pushes the plastic fastener to be assembled on the shell, the shell may shake due to the large force, thereby causing inaccurate assembly position. In this solution, a fixed column is set. When the pushing platform pushes the clamp base to move up to the highest point, the fixed column just directly abuts against the upper end surface of the shell, thereby fixing the shell, making the assembly process more stable.

[0023] Preferably, the clamp comprises a finger cylinder and a clamp fixed on two clamping fingers of the finger cylinder, and a limiting block is provided on one side close to the finger cylinder at an end surface of one clamp close to the other clamp.

[0024] By adopting the above technical scheme, when the clamping claw clamps the plastic fastener, the clamped state of the plastic fastener will determine whether it can be directly inserted into the first through hole. In this scheme, a clamping head is provided on the clamping finger of the finger cylinder, and a limit block is provided on one of the clamping heads. When the plastic fastener is clamped by the clamping head, the limit block is firstly abutted against the plastic fastener, and then the clamping head is used to clamp it, so as to maintain the clamped shape of the plastic fastener, thereby making it more convenient and more accurate to insert the subsequent plastic fastener into the first through hole.

[0025] In summary, the beneficial technical effects of this application are:

[0026] 1. When the plastic fastener assembly machine is used, the plastic fasteners are gathered in the vibrating loading tray. As the vibrating loading tray works, the plastic fasteners are vibrated into the loading slideway in turn. The plastic fasteners are clamped and moved by the clamps in the three-coordinate directions until the plastic fasteners enter the material transfer base. The material transfer plate moves horizontally to move the plastic fasteners in the material feed base out horizontally. Then the loading rod moves vertically and pushes the plastic fasteners through the loading table. At this time, the positioning fixture clamps the shell. The plastic fasteners are directly connected with the shell under the push of the loading rod, thereby completing the assembly of the shell and the plastic fasteners. The entire assembly process is completed by the machine, which greatly improves the assembly efficiency.

[0027] 2. When assembling, the clamp inserts the plastic fastener into the first through hole of the material transfer base, and the plastic fastener slides directly into the second through hole along the first through hole. When the material transfer plate moves horizontally to the third through hole aligned with the second through hole, the plastic fastener enters the third through hole and abuts against the upper end surface of the support bar. As the material transfer plate moves horizontally, the plastic fastener moves along with it. When it moves to the third through hole aligned with the loading channel, the loading rod can slide vertically and insert into the third through hole, thereby pushing the plastic fastener into the loading channel and finally assembling, so that the plastic fastener is more accurate and more stable during the transmission process, reducing the occurrence of errors, reducing the assembly stop phenomenon caused by transmission errors, and further accelerating the assembly efficiency;

[0028] 3. Push the fixture base vertically upward through the pushing table to make the fixture base separate from the conveying track, so that the fixture base remains in a relatively horizontal state before assembly, thereby ensuring the accuracy of subsequent assembly. At the same time, when assembling plastic fasteners, the downward pressure of the loading rod will be relatively large. In this solution, the fixture base is supported by the pushing table, making the assembly process more stable. At the same time, the pushing table remains in a horizontal position, and the position of the fixture base can also be made more accurate through the pushing table. BRIEF DESCRIPTION OF THE DRAWINGS
