[0065] In the embodiments of this utility model, the same reference numerals denote the same parts, and for the sake of brevity, detailed descriptions of the same parts are omitted in different embodiments.

[0066] like Figure 1 and Figure 2 As shown, this embodiment provides a welding fixture module for welding electrical components 100.

[0067] Exemplarily, the electric appliance assembly 100 to be welded includes a housing plate 101, an electronic device 102 and a circuit board 103, the electronic device 102 is connected to the housing plate 101, and a first end and a second end of the electronic device 102 are respectively arranged on opposite sides of the housing plate 101, and the circuit board 103 is welded to the second end of the electronic device 102.

[0068] The welding tool fixture module includes a first tool 1, the first tool 1 includes a base 11, at least one first support part 12 and at least one second support part 13. The first support part 12 and the second support part 13 are both connected to the base 11, the first support part 12 has a first support surface 121, the second support part 13, the first support surface 121 and the base 11 are sequentially and spacedly arranged; the first support surface 121 is used for supporting the housing plate 101, the second support part 13 is used for supporting the circuit board 103, and the vertical distance between the first support surface 121 and the base 11 is greater than the protruding height of the first end of the electronic device 102 relative to the housing plate 101; the at least one first support part 12 and the at least one second support part 13 are diagonally arranged relative to the electric appliance assembly 100.

[0069] As shown in Figure 1 , the second support part 13 has a second support surface 131, and the second support surface 131 is used for supporting the circuit board 103.

[0070] Referring to the orientation in Figure 2 , the second support part 13 is arranged on both sides of the circuit board 103, and the first support part 12 is arranged on opposite sides of the housing plate 101, so that the housing plate 101 and the circuit board 103 can be stably supported.

[0071] In some embodiments, for each electric appliance assembly 100, only one first support part 12 and one second support part 13 can be arranged, and the one first support part 12 and the one second support part 13 are diagonally arranged relative to the electric appliance assembly 100 to be welded. Exemplarily, the second support part 13 is arranged at the upper left corner position in Figure 2 , and the first support part 12 is arranged at the lower right corner position; or the second support part 13 is arranged at the upper right corner position in Figure 2 , and the first support part 12 is arranged at the lower left corner position, which can also support the housing plate 101 and the circuit board 103.

[0072] In some embodiments, the first support part 12 and the second support part 13 are arranged on the same side of the electric appliance assembly 100 to be welded. Exemplarily, the first support part 12 and the second support part 13 are arranged on the same side of the electric appliance assembly 100 to be welded in Figure 2For example, the position in the shell plate 101 is taken as an example, the first support part 12 is arranged on both sides of the shell plate 101, but the second support part 13 is arranged on only one side of the circuit board 103, and the shell plate 101 and the circuit board 103 can be supported, and the welding of the electronic device 102 and the circuit board 103 is facilitated. Alternatively, the first support part 12 is arranged on only one side of the shell plate 101, but the second support part 13 is arranged on both sides of the circuit board 103, and the shell plate 101 and the circuit board 103 can be supported, and the welding of the electronic device 102 and the circuit board 103 is facilitated.

[0073] For example, the electronic component 100 to be welded is a time relay, and the electronic device 102 is a dial. Figure 1 and Figure 2 At this time, the electronic device 102 is a dial, the first end of the dial is a dial operation end 1021 which protrudes from the outer wall of the shell plate 101, and the second end is a welding end 1022 which is welded to the circuit board 103.

[0074] As shown in Figure 2 , a gap exists between the lowest point of the dial operation end 1021 and the upper surface of the base 11.

[0075] The welding tool clamp module provided by the embodiment of the present application forms a semi-finished product after the shell plate 101, the electronic device 102 and the circuit board 103 are preliminarily assembled, the semi-finished product is placed on the first tool 1, the first support surface 121 of the first support part 12 supports the shell plate 101, the second support part 13 supports the circuit board 103, and then the second end of the electronic device 102 and the circuit board 103 can be welded. Since the vertical distance between the first support surface 121 and the base 11 is greater than the protruding height of the first end of the electronic device 102 relative to the shell plate 101, when the shell plate 101 is placed on the first support surface 121, a space for avoiding the first end of the electronic device 102 is formed between the shell plate 101 and the base 11, and the first end of the electronic device 102 is prevented from interfering with the base 11, thereby effectively solving the problem that the shell plate 101 cannot be placed on a plane to weld the circuit board 103 and the electronic device 102, and the welding operation is facilitated. Moreover, since the second support part 13 supports the circuit board 103, when the circuit board 103 is welded, the welding force acts on the circuit board 103 and the second support part 13, and does not act on the electronic device 102 and the shell plate 101, thereby avoiding the problems of breakage and damage of the shell plate 101 and damage of the dial caused by the welding force, and reducing the scrap cost.

[0076] When the welded electronic component 100 is a time relay, after the shell plate 101 is placed on the first support surface 121, the space between the shell plate 101 and the base 11 can avoid the protruding dial operation end 1021, and the welding operation is more convenient.

[0077] It can be understood that the welding tooling fixture module provided by the embodiment is not limited to welding the above-mentioned electrical component, but can also be used for welding other electrical components with other structural forms, such as all electrical components containing circuit boards. When the circuit boards of the electrical components are welded, the welding tooling fixture module can be used.

[0078] As shown in Figure 1 and Figure 3 , the first tooling 1 further comprises a plurality of connection plates 15 arranged at intervals, the first end of the connection plate 15 is connected to the base 11, and the second end of at least one of the adjacent two connection plates 15 is provided with a second support part 13 facing the other. The adjacent connection plates 15 and the base 11 surround to form a sliding groove 10, the first support part 12 is arranged in the sliding groove 10, and the first end of the sliding groove 10 has a first opening 110 allowing the electrical component 100 to slide in, and the second end has a second opening 120 allowing the electrical component 100 to slide out.

[0079] By arranging a plurality of connection plates 15 arranged at intervals, the sliding groove 10 can be formed between the base 11 and the connection plate 15. The electrical component 100 (for example, a time relay) is slid into the sliding groove 10 from the first opening 110 of the sliding groove 10, and the housing plate 101 is placed on the first support part 12, and the circuit board 103 is placed on the second support part 13. Then the welding process of the circuit board 103 and the code dial can be carried out. After welding is completed, the first tooling 1 is inclined, so that the time relay slides out through the second opening 120 of the sliding groove 10.

[0080] For the sake of description, as shown in Figure 1 and Figure 3 , it is defined that the time relay slides into the sliding groove 10 along the X direction, and two first support parts 12 are arranged along the Y direction in the sliding groove 10, and the second support part 13, the first support surface 121 and the base 11 are arranged along the Z direction. Wherein, the X direction, the Y direction and the Z direction are perpendicular to each other.

[0081] Further, the two ends of the sliding groove 10 along the X direction have the above-mentioned first opening 110 and second opening 120. The first support part 12 and the second support part 13 both extend along the X direction. More specifically, a plurality of connection plates 15 are arranged along the Y direction on the base 11, a plurality of sliding grooves 10 are formed between the base 11 and the connection plate 15, and a plurality of sliding grooves 10 are arranged along the Y direction. Each sliding groove 10 can accommodate one or more time relays at the same time, so that the first tooling 1 can weld the circuit board 103 and the code dial of a plurality of time relays at a time. After welding is completed, the first tooling 1 is inclined, so that the plurality of time relays slide out of the first tooling 1 from the second opening 120.

[0082] In some optional embodiments, the first support portion 12 is height-adjustably disposed on the base 11 relative to the base 11. On the one hand, this allows the distance between the first support surface 121 and the second support surface 131 to match the distance between the time relay circuit board 103 and the housing plate 101. When the housing plate 101 is placed on the first support surface 121, the circuit board 103 is precisely placed on the second support surface 131. On the other hand, by adjusting the height of the first support portion 12, the first tooling 1 can be adapted to different models of time relays. In actual use, the height of the first support portion 12 is adjusted according to the specific model of the time relay to improve the versatility of the first tooling 1, making it adaptable to various time relays and reducing the production cost of the tooling.

[0083] In some alternative embodiments, the first support portion 12 and the base 11 can be integrally formed. In this case, the height of the first support portion 12 relative to the base 11 is not adjustable, which enables the first support portion 12 to have a stable position relative to the base 11. At the same time, it is more convenient to manufacture, does not require post-assembly, and can ensure the connection strength between the first support portion 12 and the base 11.

[0084] like Figure 2 , Figure 3 as well as Figure 4 As shown, exemplarily, to achieve height adjustment of the first support portion 12, the first tooling 1 further includes a height adjustment member 14. The first support portion 12 is provided with an internal threaded hole 122, and the height adjustment member 14 is screwed into the internal threaded hole 122 and abuts against the base 11. By screwing the height adjustment member 14, the first support portion 12 can be raised or lowered relative to the base 11, thereby achieving height adjustment of the first support surface 121 relative to the upper surface of the base 11.

[0085] For example, each first support portion 12 is threaded with a plurality of height adjustment members 14, which are spaced apart along the X direction to ensure consistent height adjustment of the first support portion 12.

[0086] like Figure 4 As shown, a countersunk groove 123 communicating with the internal threaded hole 122 is recessed on the first support surface 121. One end of the height adjustment member 14 is located in the countersunk groove 123, so that the height adjustment member 14 can be hidden in the countersunk groove 123 and will not protrude from the first support surface 121, thus preventing the outer shell plate 101 of the time relay from falling on the height adjustment member 14.

[0087] For example, see Figure 2 and Figure 4 The height adjustment component 14 is a screw, the screw part of which passes through the countersunk groove 123 and is screwed into the internal threaded hole 122, and its head is hidden in the countersunk groove 123.

[0088] Further, seeFigure 3 and Figure 5 The second support part 13 is provided with an operation hole 132 opposite to the inner threaded hole 122, and the operation hole 132 is configured to pass through a tool for screwing the height adjusting part 14, and the tool is used to pass through the operation hole 132 and engage with the height adjusting part 14, so as to screw the height adjusting part 14 to realize the height adjustment of the first support part 12 relative to the base 11.

[0089] Referring to Figure 3 The base 11 is concavely provided with a mounting groove 111, and the mounting groove 111 is engaged with the first support part 12 to position the installation of the first support part 12 on the base 11 and improve the stability after installation. At the same time, due to the limitation of the groove wall of the mounting groove 111, when the height of the first support part 12 is adjusted, the first support part 12 will not be out of the mounting groove 111.

[0090] In some other embodiments, one or more shims can be added in the mounting groove 111, and the first support part 12 is placed on the shims to realize the height adjustment of the first support part 12 relative to the base 11.

[0091] Alternatively, in some embodiments, the first support part 12 can be screwed on the base 11 by screws, and different heights of the first support part 12 can be replaced according to the specific model of the time relay.

[0092] As shown in Figure 6 and Figure 7 , the first support part 12 is fixed with the base 11 and the connecting plate 15, and the three are integrally formed to ensure the overall strength of the first tool 1. Two first support parts 12 are arranged in the sliding groove 10 at intervals, and are respectively used to support both ends of the shell plate 101. Both ends of the circuit board 103 are supported by a second support part 13.

[0093] As shown in Figure 8 and Figure 9 , the first support part 12 is fixed with the base 11 and the connecting plate 15, and the three are integrally formed to ensure the overall strength of the first tool 1. Moreover, two first support parts 12 are arranged in the sliding groove 10 at intervals, and are respectively used to support both ends of the shell plate 101. Only one end of the circuit board 103 is supported by the second support part 13.

[0094] Referring to Figure 8 and Figure 10At least one end of the first supporting part 12 is provided with a first guide surface 124, which is connected with the first supporting surface 121; in the direction away from the first supporting surface 121, the first guide surface 124 gradually extends in the direction away from the second supporting part 13, and the vertical distance between the first guide surface 124 and the base 11 gradually decreases. In this way, the housing plate 101 of the time relay can slide along the first guide surface 124 to the first supporting surface 121, so that the time relay can be more smoothly slid into the sliding groove 10.

[0095] Exemplarily, the first guide surface 124 comprises a guide arc surface 1241 and a guide inclined surface 1242, the guide inclined surface 1242 is connected with the first supporting surface 121 through the guide arc surface 1241, so that the connection between the guide inclined surface 1242 and the first supporting surface 121 is more smooth, avoiding the time relay from being stuck when sliding into the sliding groove 10.

[0096] As shown in Figure 6 , Figure 8 and Figure 10 , in some embodiments, the connecting plate 15 is provided with a second guide surface 151 at least at one end of the first opening 110, and the second guide surface 151 extends obliquely in the direction away from the first supporting part 12, so that the first opening 110 forms a flared structure, facilitating the time relay to enter the sliding groove 10.

[0097] Exemplarily, the first guide surface 124 is arranged at both ends of the first supporting part 12 along the X direction, and the second guide surface 151 is arranged at both ends of the connecting plate 15 along the X direction, so that the time relay can be slid into the sliding groove 10 from either end and slid out from the other end.

[0098] As shown in Figure 11 , the welding tool clamp module further comprises a second tool 2, and the second tool 2 is provided with a limiting clamping groove 21 which is clamped with the housing plate 101. In combination with Figure 12 , the outer surface of the housing plate 101 needs to be attached with a nameplate 104, when attaching, the housing plate 101 is clamped into the limiting clamping groove 21, and the outer surface of the housing plate 101 faces upward, so that the nameplate 104 can be attached on the housing plate 101, the operation of attaching the nameplate 104 is more convenient, and the force of pressing the nameplate 104 is applied to the bottom wall of the limiting clamping groove 21, which will not cause damage to the housing plate 101.

[0099] Referring to Figure 11 , the outer edge of the limiting clamping groove 21 is provided with an inner chamfer structure 211, so that the opening of the limiting clamping groove 21 is enlarged, thereby making the housing plate 101 more smoothly placed in the limiting clamping groove 21.

When the nameplate 104 is pasted on the outer surface of the shell plate 101, the bracket 1011 is inserted into the first avoiding groove 23, so that the shell plate 101 can be clamped with the limiting clamping groove 21, and the bracket 1011 is prevented from interfering with the bottom wall of the limiting clamping groove 21. Further, the inner wall of the shell plate 101 is provided with a plurality of brackets 1011, and the bottom wall of the limiting clamping groove 21 is provided with a plurality of first avoiding grooves 23 corresponding to the brackets 1011.

[0103] In the embodiment, as shown in Figure 13 and Figure 14 , the limiting clamping groove 21 on the second tool 2 can also be used to invert the shell plate 101, so as to realize the welding of the second end of the circuit board 103 and the electronic device 102. The bottom wall of the limiting clamping groove 21 is provided with the second avoiding groove 24 for avoiding the first end of the electronic device 102, so that the shell plate 101 can be inverted in the limiting clamping groove 21 after the electronic device 102 is installed, and the electronic device 102 is prevented from interfering with the bottom wall of the limiting clamping groove 21.

[0104] Specifically, taking the time relay as an example, after the dial is installed on the shell plate 101 and the circuit board 103 and the welding end 1022 of the dial are preliminarily fixed, the shell plate 101 is inverted and placed in the limiting clamping groove 21. Since the limiting clamping groove 21 is clamped with the shell plate 101, the semi-finished product of the time relay can be fixed on the second tool 2. When the circuit board 103 and the dial are welded, since the shell plate 101 contacts with the bottom wall of the limiting clamping groove 21, the shell plate 101 can maintain its form and will not be damaged due to the welding force. Referring to Figure 13 and Figure 14The dialing operation end 1021 of the dialer is located in the second avoiding groove 24, so that the shell plate 101 can be clamped with the limiting clamping groove 21 in a posture with the inner surface upward.
