[0028] Referring to Figures 1 to 5 As shown in the drawings, the application provides a mover module, which can be applied to a linear motor module. The mover module comprises a sliding seat 100 and a support plate 200. The sliding seat 100 comprises a first support arm 101 and a second support arm 102 located at the left and right ends. The sliding seat 100 further comprises a connecting portion 103 connecting the first support arm 101 and the second support arm 102. The first support arm 101, the second support arm 102 and the connecting portion 103 are only different parts on the sliding seat 100, which can be an integral structure or a structure formed by splicing and fixing multiple structures. The sliding seat 100 forms a gap 104 penetrating through the front and rear ends of the sliding seat 100 between the first support arm 101 and the second support arm 102. The sliding seat 100 is provided with a mover unit 105 in the gap 104. The mover unit 105 is fixedly connected with the connecting portion 103. The support plate 200 is connected with the first support arm 101 and the second support arm 102 on the sliding seat 100 respectively. The position of the support plate 200 corresponds to the position of the gap 104. In the application, the gap 104 for placing the mover unit 105 is formed between the first support arm 101 and the second support arm 102. In order to improve the stability of the structure of the mover module in the embodiment of the application, the support plate 200 is arranged on the sliding seat 100 in the gap 104. The support plate 200 is connected with the first support arm 101 and the second support arm 102. Through the arrangement of the support plate 200, the first support arm 101 and the second support arm 102 are not easily contracted, thereby improving the stability of the structure of the mover module.

[0029] It can be understood that, as shown in Figure 1 The bottom inner side of the first support arm 101 and the second support arm 102 is provided with a ball returning guide groove 106 for returning the ball. In an embodiment, the first support arm 101 and the second support arm 102 are symmetrically arranged at the left and right ends of the sliding seat 100. The ball returning guide grooves 106 on the first support arm 101 and the second support arm 102 are also symmetrically arranged at the bottom inner side of the corresponding first support arm 101 and the second support arm 102. As shown in Figure 2As shown, the embodiment of the present application also provides a linear motor module, the linear motor module comprising a stator module, wherein the stator module is arranged in cooperation with the mover module, the stator module comprising a base 300 and a stator unit 301 arranged on the base 300, and the base 300 is provided with a sliding groove 302 at both ends. It can be understood that in the embodiment of the present application, the sliding groove 302 is arranged at the horizontal left and right ends of the base 300 as an example, the sliding groove 302 corresponds to the position of the ball return guide groove 106, and the ball return guide groove 106 and the sliding groove 302 can accommodate the ball. After the ball moves in the channel formed by the ball return guide groove 106 and the sliding groove 302, the ball can be returned to the ball return guide groove 106 inside the sliding seat 100, so that the mover module can move on the linear motor module. The mover unit 105 corresponds to the position of the stator unit 301, and forms an acting force therebetween. The structure of the linear motor module is not limited in the present application, and other structures can also be included in the linear motor module under the premise of meeting the requirements of the embodiment of the present application.

[0030] It should be noted that due to the strong acting force between the mover unit 105 and the stator unit 301, the mover module will be attracted by the stator module below, so that sufficient support force is needed to support the mover module. Since the mover unit 105 is located in the middle of the sliding seat 100, the first support arm 101 and the second support arm 102 on both sides will be concave inwardly. Therefore, in the embodiment of the present application, the support plate 200 is arranged to connect the first support arm 101 and the second support arm 102, which greatly improves the stability of the structure of the mover module, so that the two support arms of the mover module can be fixed at a predetermined position.

[0031] In an embodiment, the support plate 200 is provided with two, and the two support plates 200 are respectively connected to the front and rear ends of the sliding seat 100. The support plate 200 corresponds to the position of the notch 104, specifically, in order to further improve the stability of the structure of the mover module, the support plate 200 is arranged at the notch 104 corresponding to the front and rear ends of the sliding seat 100, and the support plate 200 is respectively connected to the first support arm 101 and the second support arm 102 corresponding to the front and rear ends of the sliding seat 100.

[0032] Referring to Figure 1 and Figure 3As shown in the figure, in an embodiment, the size of the support plate 200 corresponds to the size of the notch 104, so that the support plate 200 covers the notch 104. It can be understood that the size of the notch 104 in the embodiment of the present application corresponds to the size of the mover unit 105, and the notch 104 is provided to place the appropriate mover unit 105 on the slide 100. The mover unit 105 is connected in the upper connecting part 103 during installation to achieve fixation. Therefore, in order to better improve the stability of the mover module structure, the size of the support plate 200 corresponds to the size of the notch 104. Specifically, the size of the support plate 200 should meet the size of covering the notch 104, so as to further improve the effect of supporting stability.

[0033] Referring to Figure 1 and Figure 5 As shown in the figure, in an embodiment, the bottom inner side of the first support arm 101 and the second support arm 102 is provided with a ball return guide groove 106 for placing the ball to realize the ball return. The ball return guide groove 106 can be divided into two parts. One part is located at the bottom inner side edge of the first support arm 101 and the second support arm 102, which is used to correspond to the sliding groove 302 on the stator module of the linear motor module to form a channel for ball movement. The other part is located inside the first support arm 101 and the second support arm 102 to form an internal channel. Referring to Figure 1 and Figure 4 As shown in the figure, the two channels are connected together through the return end cover 107 provided at the first support arm 101 and the second support arm 102. The slide 100 is provided with a return end cover 107 corresponding to the position of the ball return guide groove 106 at the first support arm 101 and the second support arm 102. The return end cover 107 is provided with a return groove 1071, which is communicated with the ball return guide groove 106 to realize the ball return. It can be understood that different numbers of return end covers 107 can be provided according to actual needs in the embodiment of the present application. For example, in an embodiment, four return end covers 107 are provided and located on the first support arm 101 and the second support arm 102 of the slide 100 at the front and rear ends. In another embodiment, the return end covers 107 can also be combined to form a large return end cover 107. For example, the return end covers 107 with the return grooves 1071 at the same end are combined into a whole. The return end cover 107 with the whole design at one end is located on the corresponding first support arm 101 and second support arm 102 at the front end or rear end of the slide 100. The present application does not make specific limitation on this.

[0034] It should be noted that the return groove 1071 is provided with a curved arc, so that the bottom return ball guide groove 106 returns the ball along the curved return groove 1071 to the part of the return ball guide groove 106 provided in the slide 100. The return groove 1071 is a guide groove with a certain curved arc. By setting a certain curved arc, the ball can move more smoothly, thereby improving the smoothness of the mover module movement.

[0035] It should be noted that the return groove 1071 is bent towards the middle of the slide 100, and the distance of the return groove 1071 bent towards the middle of the slide 100 is not large, which can meet the requirement of returning the ball and save space for the mover unit 105 to be provided in the slide 100.

[0036] Referring to Figure 4 It should be noted that the return groove 1071 is bent towards the middle of the slide 100, and the distance of the return groove 1071 bent towards the middle of the slide 100 is not large, which can meet the requirement of returning the ball and save space for the mover unit 105 to be provided in the slide 100.

[0037] Referring to Figure 4 It should be noted that the return groove 1071 is bent towards the middle of the slide 100, and the distance of the return groove 1071 bent towards the middle of the slide 100 is not large, which can meet the requirement of returning the ball and save space for the mover unit 105 to be provided in the slide 100.

[0038] Referring to Figure 4 It should be noted that the return groove 1071 is bent towards the middle of the slide 100, and the distance of the return groove 1071 bent towards the middle of the slide 100 is not large, which can meet the requirement of returning the ball and save space for the mover unit 105 to be provided in the slide 100.

[0039] Referring to Figure 1As shown in the figure, in an embodiment, a self-lubricating pipe 108 is arranged in the ball return guide groove 106, the self-lubricating pipe 108 is arranged along the ball return guide groove 106, and the self-lubricating pipe 108 contains lubricating liquid such as lubricating oil. By arranging the self-lubricating pipe 108, the balls can move more smoothly in the ball return guide groove 106.

[0040] In an embodiment, the support plate 200 is away from the bottom of the first support arm 101 and the second support arm 102 by a preset distance, and the preset distance is related to the height of the stator module of the linear motor module. For details, refer to Figure 4 and Figure 5 As shown in the figure, in an embodiment, the lower part of the support plate 200 does not exceed the height of the gap 104, so that the support plate 200 is away from the bottom of the first support arm 101 and the second support arm 102 by a preset distance. When the mover module is arranged on the linear motor module, the arrangement of the support plate 200 does not affect the operation of the linear motor module, and no additional structure needs to be designed to adapt to the arrangement of the support plate 200, thereby reducing the application cost.

[0041] For details, refer to Figure 1 and Figure 5 As shown in the figure, in an embodiment, the power outlet 109 is arranged on the side of the first support arm 101 or the second support arm 102 of the sliding seat 100, and the power outlet 109 is used to penetrate the first support arm 101 or the second support arm 102 and communicate with the gap 104. The mover module needs to be connected with the power supply to realize power-on control, and then control the movement of the mover module on the linear motor module. In the embodiment of the application, the power supply interface of the mover module is arranged on the side of the sliding seat 100, that is, on the side of the first support arm 101 or the second support arm 102. Arranging the opening on the side can avoid connecting the power line to the front and rear ends of the mover module, and avoid occupying the length of the linear motor module to meet the wiring. The power outlet 109 communicates with the gap 104, so that the power line can be connected to the mover unit 105 arranged in the gap 104 through the power outlet 109.

[0042] For details, refer to Figure 5As shown, in an embodiment, the mover unit 105 has a gap 110 with at least one of the first support arm 101 and the second support arm 102, so that the mover unit 105 is spaced apart from at least one of the first support arm 101 and the second support arm 102. The mover unit 105 generates heat in operation and produces a thermal effect. In order to avoid the influence of the thermal expansion of the mover unit 105 on the mover module, the embodiment of the present application reserves a certain space for the mover unit 105. The mover unit 105 has a gap 110 with one or both of the first support arm 101 and the second support arm 102 in the gap 104. In the heating process, the expansion of the mover unit 105 due to the existence of the gap 110 does not affect the operation of the first support arm 101 or the second support arm 102 beside it, thereby improving the stability of the structure.

[0043] It can be understood that the linear motor module in the embodiment of the present application can include the mover module described in any one of the above embodiments.

[0044] It should also be understood that the various embodiments provided by the embodiment of the present application can be combined arbitrarily to achieve different technical effects.
